Description

  The present invention relates to a digital broadcast receiving apparatus and a digital broadcast receiving method capable of simultaneously receiving and recording a digital broadcast signal including a plurality of hierarchies transmitted in a hierarchy in a receiving apparatus body.

Japan's terrestrial digital broadcasting system is called integrated terrestrial broadcasting (abbreviated as ISDB-T) and has several characteristics. One of the characteristics is one channel. In order to enable services for fixed reception and mobile / mobile reception, there is hierarchical transmission in which the carrier modulation method and error correction strength can be changed for each segment.
In terrestrial digital broadcasting, the channel bandwidth is 6 MHz, and 6 MHz is divided into 14 parts, and 13 of them (about 5.6 MHz width) are used for broadcasting. Each of the 13 frequency blocks (about 429 kHz width) is called a segment.

Regarding the fixed reception service and mobile / mobile reception service, specifically, a broadcast program includes 12 segments for fixed reception (hereinafter abbreviated as 12 segments) and one segment for mobile (hereinafter referred to as 12 segments) in the broadcast channel. Are abbreviated as 1 segment).
For the time being, it is expected that simulcasting that provides the same program in 12 segments and 1 segment will be implemented. The 12-segment broadcasting can be a high-definition broadcast (HDTV) that provides high-definition video and audio in a wide band, but is also called a weak-layer broadcast that is easily affected by noise. 1-segment broadcasting enables mobile broadcasting that is modulated in a narrow band and is resistant to fluctuations in radio waves, and is also called high-level broadcasting that is less susceptible to noise.

  By the way, in recent years, with regard to copy control of broadcast programs, when recording once in the receiver unit and copying it to removable media, consideration has been given to reducing the number of times for copy one generation (COG) operations. And N times (N is 2 or more, for example, 9 times) will be allowed to be copied. In this case, the number of copies of the COG program must be managed in the receiving apparatus body.

  In the recording of 12-segment broadcasting, it is possible to record using EPG information for 8 days including the day of broadcasting using program guide (EPG) information, but in the recording of 1-segment broadcasting, 8 programs are recorded. Only the previous EPG information can be used, and the recording reservation for the next day is often impossible, and the recording reservation for the next day cannot be reserved at all.

On the other hand, as an apparatus for receiving and recording / reproducing digital broadcast, 12-segment content and 1-segment content included in the digital broadcast channel are simultaneously recorded, and 1-segment content and management information thereof can be moved to a mobile terminal. A recording / reproducing apparatus is disclosed (see Patent Document 1).
JP 2007-251803 A

  However, in Patent Document 1, 12 segments and 1 segment can be recorded at the same time, but one of 12 segments and 1 segment is not recorded and recording is not performed. It was impossible to make a recording reservation for 8 days, similar to the 12-segment EPG recording. Furthermore, it has not been considered at all how to manage the number of times of copying accompanying relaxation of the number of times limit.

  Therefore, in view of the above problems, the present invention can specify one of 12 segments and one segment and record it on the receiving apparatus main body, and the recording reservation similar to 12 segment EPG recording can be performed for one segment recording. It is an object of the present invention to provide a digital broadcast receiving apparatus and a digital broadcast receiving method that can be performed, and that can manage the number of copies that accompanies relaxation of the number of times.

A digital broadcast receiving apparatus according to the present invention includes a receiving means for receiving a digital broadcast signal including a 12-segment broadcast signal and a 1-segment broadcast signal, a recording medium provided in the main body of the receiving apparatus, on which a program is recorded, A separating means for separating the first program transmitted in the 12 segments from the digital broadcast signal received by the receiving means and the second program transmitted in the one segment; and the 12 segments from the digital broadcast signal. Means for acquiring program guide information of the first program to be transmitted, and reservation of recording using the program guide information of the first program, and reservation of the first program sorted by the sorting means At the time, only one of the first programs out of the second programs without program guide information is recorded on the recording medium, or at the time of the first program and the reservation time Means for selectively displaying whether or not both of the second programs having no program guide information are recorded on the recording medium.

With this configuration, when recording the second layer (for example, 1-segment broadcasting), the recording reservation can be made using the program guide information of the first layer (for example, 12-segment broadcasting). For example, it is possible to make a reservation for one week ahead, and the reservation information is detailed.
The 12-segment broadcast and the 1-segment broadcast are usually simultaneous broadcasts, and the same program is broadcast in the same time zone. Therefore, by determining (detecting) that each broadcast channel is simultaneous broadcast, Even when recording a broadcast, it is possible to display in advance that the 12-segment EPG information of the same program content can be used and that 1-segment recording is possible, and this can be used effectively. .

In addition to recording the first program transmitted in 12 segments, the screen displays whether to record the second program transmitted in 1 segment as well as recording the first program transmitted in 12 segments. Therefore, when the restriction on the number of times of copying is relaxed, the first or the second is selected according to the increase or decrease in the recordable capacity of the recording medium in the main body of the receiving apparatus or the image quality required for viewing. This program can be arbitrarily designated.
A digital broadcast receiving apparatus according to the present invention includes a receiving means for receiving a digital broadcast signal transmitted hierarchically with a plurality of hierarchies, a recording medium provided in the receiving apparatus main body for recording a program, and received by the receiving means. A classification means for separating the first program transmitted from the digital broadcast signal in the first hierarchy and the second program transmitted in the second hierarchy different from the first hierarchy; and from the digital broadcast signal The first program and the second program using the program guide information of the first program in the first hierarchy and the program guide information of the first program and the second program included in the digital broadcast signal. The simulcast determination means for determining whether or not the same program is broadcast in the same time zone, and the determination result of the simulcast determination means is the simulcast, and the determination means 1 and 2 Control to record both sets on the recording medium at the same time, control the first and second programs to be recorded in separate files, and also record the management information for associating both programs in the storage means Means.

  With this configuration, the first program transmitted on the first layer and the second program transmitted on the second layer can be identified by layer information or PID (packet identification). Can be recorded as separate files on the same recording medium. When recording in a separate file in this way, when the restriction on the number of copies is relaxed, the selection when selecting the program of the first hierarchy or the second hierarchy with different information amount and image quality is selected. The operation can be easily performed. If the first and second programs have the same contents and broadcast in the same time zone, the correspondence between the two programs (specifically, data indicating the same contents) is recorded as management information. Thus, when copying or moving to an external recording medium after recording, it becomes useful information for selecting from two programs having the same contents but different hierarchies.

Furthermore, the digital broadcast receiving apparatus according to the present invention is preferably configured to copy or move either the first program or the second program to the removable medium with respect to the interface unit to which the removable medium can be attached and the program recorded on the recording medium. And means for designating whether to do.
With this configuration, for the recorded program recorded on the receiving apparatus main body, either the first layer program or the second layer program can be designated, and the content can be copied and moved to the removable medium.

  Furthermore, the digital broadcast receiving apparatus of the present invention is preferably provided in the apparatus main body, and management information for copy control including the number of times of copying to an external recording medium including the removable medium connectable to the apparatus main body, Management information storage means for managing each of the first and second programs as separate files is further provided. The management information storage means may be a partial area of the recording medium in the receiving apparatus main body.

Furthermore, the digital broadcast receiving apparatus of the present invention preferably further comprises display means for performing screen display of selection items necessary in the process of recording at least one of the first and second programs.
With this configuration, EPG information for recording reservation, recorded program list, copy history, and the like can be displayed on the display means.

  A digital broadcast receiving method according to the present invention includes a receiving step for receiving a digital broadcast signal that is hierarchically transmitted in a plurality of layers, and a first program transmitted on a first layer from the digital broadcast signal received in the receiving step. And a step of separating a second program transmitted in a second layer different from the first layer, and a step of obtaining program guide information of the first program in the first layer from the digital broadcast signal Whether the first program and the second program are broadcasting the same program in the same time zone using the program schedule information of the first program and the second program included in the digital broadcast signal And when the recording reservation is made using the program guide information of the first program when the determination result of the simulcast determination step is simulcast. A step of displaying a screen for designating which one of the separated first and second programs is recorded on a recording medium in the receiving apparatus main body or both programs are recorded. It is.

  By this method, when recording the second layer (for example, 1 segment broadcasting), the recording reservation can be made using the program guide information of the first layer (for example, 12 segment broadcasting), so even if it is 1 segment broadcasting. For example, it is possible to make a reservation for one week ahead, and the reservation information is detailed. In addition to recording the first program transmitted in 12 segments, the screen displays whether to record the second program transmitted in 1 segment as well as recording the first program transmitted in 12 segments. Therefore, when the restriction on the number of times of copying is relaxed, the first or the second is selected according to the increase or decrease in the recordable capacity of the recording medium in the main body of the receiving apparatus or the image quality required for viewing. This program can be arbitrarily designated.

  According to the present invention, one of 12 segments and 1 segment can be designated and recorded on the receiving device body, and recording reservation similar to 12 segment EPG recording can be performed for 1 segment recording. In addition, it is possible to provide a digital broadcast receiving apparatus and a digital broadcast receiving method capable of managing the number of copies associated with the restriction on the number of times.

Embodiments of the invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a block diagram of a digital broadcast receiving apparatus according to a first embodiment of the present invention. Here, a digital broadcast receiver for fixed reception will be described, but the present invention can also be applied to a digital broadcast receiver for portable / mobile reception.

  In FIG. 1, a digital broadcast receiving apparatus 100 includes an antenna 101 that receives a digital broadcast signal, a tuner unit 102 that is a receiving unit, a decryption unit 103, an encryption unit 104, and a hard disk (HD) as a recording medium. Hard disk drive section (abbreviated as HDD) 105, TS separation section 106, video decoder 107, audio decoder 108, video output section 109, audio output section 110, management information storage section 111, and IC card Interface unit (abbreviated as IC card I / F unit) 112, removable media interface unit (abbreviated as removable media I / F unit) 113, control unit 114, IC card 115, and memory card 116 as a removable medium , Display device 117, speaker 118, bassra And down 119, a remote-control interface unit (the remote control I / F unit hereinafter) 120, a remote controller 121, a.

The antenna 101 is a UHF antenna and receives digital broadcast radio waves including digital broadcast signals. The digital broadcast signal is hierarchically transmitted including a plurality of layers (for example, a weak layer as the first layer and a strong layer as the second layer) in one channel. The weak hierarchy and the strong hierarchy are usually broadcast simultaneously.
The tuner unit 102 includes a channel selection unit that selects a carrier frequency (broadcast channel) for each broadcast station, and a demodulator that performs digital demodulation, and outputs it as an MPEG2 transport stream (hereinafter abbreviated as MPEG2-TS). At that time, the tuner unit 102 receives all 13 segments of the selected broadcast channel, and outputs 12-segment TS packets and 1-segment TS packets as one stream data in an alternately arranged state. . Then, one stream data of the MPEG2-TS is input to the control unit 114, and the control unit 114 converts the TS packet of the 12-segment program corresponding to the weak layer and the TS packet of the 1-segment program corresponding to the strong layer. Layer information that can identify each layer is added (that is, a 12-segment program and a 1-segment program are separated), and a stream data with 12-segment TS packets and 1-segment TS packets mixed together. Is output and supplied to the decoding unit 103.

The decryption unit 103 releases (descrambles) the scramble applied to the program at the broadcast station using the encryption key from the management information storage unit 111.
The encryption unit 104 is for encrypting a program with an individual encryption key for each receiving device (referred to as local encryption) when recording the program on the HDD 105 of each receiving device. This is to protect the copyright, and to prevent the recorded program from being illegally moved and duplicated by an action such as removing the HDD 105 and attaching it to another device.
The HDD 105 is a recording medium provided in the receiving apparatus main body for storing (recording) the received and demodulated program data. The descrambled and locally encrypted 12-segment TS packet and 1-segment TS packet The 12-segment program and the 1-segment program are simultaneously recorded in separate files on the recording medium of the HDD 105.

  The TS separation unit 106 separates video data, audio data, data broadcast data, program guide (EPG) information (including program information), and control information from the descrambled MPEG2-TS.

The video decoder 107 performs MPEG decoding on the separated video data. Also, the audio decoder 108 performs MPEG decoding on the separated audio data.
The video output unit 109 converts the decoded video signal into a display signal and supplies it to the subsequent display device 117. Also, the audio output unit 110 converts the decoded video signal for audio output and supplies it to the subsequent speaker 118. A liquid crystal display or the like is used for the display device 117, an image is displayed, and sound is output from the speaker 118.

  The management information storage unit 111 is composed of, for example, a non-volatile memory and stores recording management information. As described later, the management information storage unit 111 associates both programs when a 12-segment program and a 1-segment program are recorded simultaneously. Management data to be performed (for example, data indicating that 12-segment and 1-segment programs are the same program when simultaneous broadcasting is being performed), the number of times the program has been copied from the HDD 105 in the receiving apparatus to an external recording medium, etc. Stores management data related to copy control.

The IC card I / F unit 112 is an interface for connecting an IC card 115 such as a B-CAS card to the bus line 119.
The removable media I / F unit 113 is an interface for connecting a memory card 116 as a removable media such as an SD ^TM card to the bus line 119.

The remote control I / F unit 120 is configured by a light receiving unit that receives, for example, an infrared signal from a remote control 121 as an operation unit and performs photoelectric conversion.
The control unit 114 controls each of the above-described receiving devices connected on the bus line 119. For example, channel selection control, selection control of 12-segment programs and 1-segment programs in the selected channel, and recording control In addition, control regarding determination of whether or not simulcasting is performed, restriction on the number of copies, and adjustment control of video and audio based on remote control operations are performed. The control unit 114 also has a clock function.

  Further, the control unit 114 separates a program transmitted in 12 segments from a digital broadcast signal received by the tuner unit 102 and a program transmitted in 1 segment, and EPG information of a 12 segment program from the digital broadcast signal. And a simulcast determination function for determining whether or not the same program is broadcast in the same time zone for a 12-segment program and a 1-segment program using EPG information included in the digital broadcast signal; When the determination result is simultaneous broadcasting, when making a recording reservation using the program guide information of the first program, either the sorted first or second program is recorded in the HDD 105 which is an internal recording medium. Or a function of displaying a screen for designating whether to record both the first program and the second program. A display device 117 is used for screen display.

  The 12-segment EPG information includes program information (H-EIT) for 8 days including the current day for use in recording reservations in addition to the program information of the program currently being broadcast. The EPG information includes program information (L-EIT) up to eight programs ahead. These pieces of program information (EIT) are transmitted from the broadcasting station side in a cycle within a predetermined fixed time interval in a section format defined in MPEG2 Systems as in data broadcasting.

  In the embodiment of the present invention, it is assumed that a digital broadcast receiving apparatus for fixed reception first receives a program transmitted in 12 segments, and when recording, if 12 segments and 1 segment are simultaneous broadcasts, It is possible to specify whether to record a program transmitted in one segment in addition to recording a program transmitted in 12 segments on the HDD 105 in the receiving apparatus main body by using the program table (EPG) information of the segment. I am doing so.

  At present, simultaneous broadcasting for broadcasting the same program in the same time zone is performed for the program transmitted in 12 segments and the program transmitted in 1 segment. As for EPG, as described above, program information for 8 days is transmitted in broadcasting by 12 segments, and program information for only 8 programs ahead is transmitted in broadcasting by 1 segment. If the Seg program is the same program and broadcasted in the same time zone (ie, simulcast), the 12-segment EPG can be used to specify a program ahead of the 1-segment EPG. When using SEG EPG, 12-segment H-EIT has more information (information types and items) than 1-segment L-EIT, making recording reservations using EPG very convenient . However, 12-segment H-EIT and 1-segment L-EIT have at least program name information.

  Also, in order to determine whether the 12-segment broadcast and the 1-segment broadcast are simultaneous broadcasts, the H-EIT program name and the L-EIT program name are compared. It is possible to determine. The determination by comparing the H-EIT program name and the L-EIT program name can be performed by the control unit 114.

Hereinafter, an example of the recording EPG and an example of the one-segment recording designation will be described with reference to FIG. FIG. 2 (a) shows a screen display example of the recorded EPG, and FIG. 2 (b) shows a screen display example of 1 segment recording designation.
Display of the recorded EPG for recording designation is performed using EPG information of 12 segments. As shown in FIG. 2 (a), the broadcasting station name is taken in the horizontal direction and the time is taken in the vertical direction, and the program names are displayed in time order for each broadcasting station. The bold line frame is a cursor display. By operating the cursor key of the remote controller 121, for example, the program B3 from station 8am to 9am is selected. When the Enter key is operated in this state, a dialog (dialog format) for confirmation of recording as shown in Fig. 2 (b) appears on the screen, confirming the broadcast station name, program name, and recording time, as well as one segment. Recording can be specified at the same time. In the present embodiment, a check box for specifying whether or not to perform 1-segment recording is also provided to specify 1-segment recording. The check mark can be input by, for example, pressing a one-segment key provided on the remote controller 121.

  In the dialog shown in FIG. 2B, when the cursor (thick line frame) is placed at the position of the OK button and the enter key on the remote controller 121 is pressed, the recording is designated. Cancel can be selected and executed by moving the cursor to the cancel button with the cursor key of the remote controller 121 and pressing the enter key. Actual recording is executed on the HDD 105 in the receiving apparatus main body together with designation of 12 segments and 1 segment at the reserved time.

  In FIG. 2, one segment recording can be specified at the same time as 12 segment recording. However, it is also possible to specify only one segment recording by software. Therefore, in the present invention, it is possible to designate recording of either 12 segments or 1 segment, or designation of recording of both 12 segments and 1 segment.

According to the first embodiment of the present invention, it is possible to specify not only recording of a program transmitted in 12 segments but also recording of a program transmitted in 1 segment using EPG of 12 segments. The convenience of specifying recording can be increased.
Since 12-segment broadcasting and 1-segment broadcasting are ordinary simulcasts and the same program is broadcast in the same time zone, it is determined (detected) that it is simulcast, and 1-segment broadcasting is recorded. Even in this case, the 12-segment EPG can be used, and the user can be notified by displaying on the screen that 1-segment recording with the same content as the 12-segment is possible. In addition, since the number of programs and the amount of program information that can be specified is larger in 12 segments than in 1 segment, the convenience of 1-segment recording reservation is increased by using 12-segment EPG.

When recording a 1-segment broadcast that is a strong hierarchy, a recording reservation can be made using EPG information of a 12-segment broadcast that is a weak hierarchy. For example, a reservation for one week ahead is possible, and the reservation information is detailed. Have the advantage of being. In addition, regarding the recording on the recording medium in the receiving apparatus main body, in addition to the recording of the program transmitted in 12 segments, it is possible to specify whether to record the program transmitted in 1 segment, so the restriction on the number of copying is relaxed When the program is executed, the recording designation of the 12-segment or 1-segment program or both programs according to the increase / decrease of the recordable capacity of the recording medium in the apparatus main body or the required image quality is specified. Is possible.
[Second Embodiment]
The configuration of the digital broadcast receiving apparatus according to the second embodiment of the present invention is the same as that shown in FIG.
In the second embodiment, the control unit 114 performs both of the function of separating the 12-segment program and the 1-segment program from the digital broadcast signal received by the tuner unit 102 and the separated 12-segment and 1-segment programs. A function for controlling recording to the HDD 105 at the same time, recording 12-segment and 1-segment programs in separate files, and recording management information for associating both programs in the management information storage unit 111, At least.

  As in the first embodiment, the control unit 114 uses the function of acquiring EPG information of a 12-segment program from the digital broadcast signal and the EPG information included in the digital broadcast signal, and the 12-segment program and the 1-segment program. A simulcast determination function for determining whether or not the same program is broadcast in the same time zone, and when this determination result is simulcast, at least one segment of EPG information of 12 segment programs is used. A function for displaying a screen for confirming whether or not to record a program and either the above-described sorted 12-segment or 1-segment program are recorded in the HDD 105, or both the 12-segment and 1-segment programs are recorded. And a function of displaying a screen for specifying whether to record.

  As a result, when a program transmitted in 12 segments and a program transmitted in 1 segment are recorded simultaneously on the HDD 105 in the receiving apparatus main body, the programs are recorded as separate files, and both programs are the same program. Management data to be associated is also recorded so as to show that

  Depending on the management data that associates a 12-segment program with a 1-segment program, either 1-segment or 12-segment recording of the target program during recording / playback, copying to a removable medium, or moving, or You can also indicate to the user whether both recordings are taking place.

  According to the second embodiment of the present invention, a program transmitted in 12 segments and a program transmitted in 1 segment can be identified by hierarchical information or PID (packet identification). It is possible to record in a separate file on the recording medium. By recording in a separate file in this way, if the restriction on the number of copies is relaxed, the selection operation when selecting a 12-segment or 1-segment program with different data amount or image quality is facilitated. It is possible to make it happen. Also, if the 12-segment and 1-segment programs are broadcast in the same content and in the same time zone, if the correspondence is recorded as management data, it is possible to copy or move to an external recording medium after recording. This is useful information when selecting a segment program or a one-segment program in consideration of the level of image quality and the amount of recordable capacity.

[Third Embodiment]
The configuration of the digital broadcast receiving apparatus according to the third embodiment of the present invention is the same as that shown in FIG.
In the third embodiment, for the program recorded in the HDD 105, the control unit 114 is a screen for designating whether a 12-segment program or a 1-segment program is to be copied or moved to the memory card 116, which is a removable medium. At least a display function is provided. Furthermore, the control unit 114 may have the functions described in the first and second embodiments.

Hereinafter, an example of a recorded program list list and an example of a dialog for displaying a history copied from 12-segment and 1-segment recording will be described with reference to FIG. FIGS. 3A to 3D show examples of screen display.
Since the list of recorded program lists shown in FIG. 3 (a) is a receiving device for fixed reception, a list of recorded programs of 12-segment programs and a state in which a 1-segment program is simultaneously recorded as necessary are displayed. Is. The bold line frame is a cursor display. By operating the cursor key of the remote controller 121, for example, the program B3 of station B is selected. The display of “1SG” along with the program display on the screen is an icon indicating that the 1-segment program B3 is recorded in addition to the 12-segment program B3. When the enter key is operated in the state of FIG. 3A, the selected recorded program B3 is reproduced, and high-definition video and audio of the program B3 recorded in 12 segments are output to the display device 117 and the speaker 118. .

  On the other hand, when the quick button or the submenu button is pressed in the state shown in FIG. 3A, a submenu as shown in FIG. 3B is additionally displayed on the screen in a pull-down format, for example. In this submenu, buttons such as copy history, copy, move, and delete are arranged. By operating the cursor keys on the remote controller 121, selecting “Copy History” with the cursor in the thick line frame and pressing the Enter key on the remote controller 121 displays a copy history dialog as shown in FIG. The In the dialog of FIG. 3 (c), for example, it is displayed that a high-quality program of 12 segments can be copied eight more times and a program of one segment can be copied four more times for program B3. The display of the number of times of copying is performed by using the technique of recording in separate files at the time of simultaneous recording of 12 seg and 1 seg as described in the second embodiment. This can be more easily realized by separately counting the number of times the recorded program B3 is copied from the file. Here, a check box for designating whether or not to copy only a program recorded in one segment is provided, so that only one segment can be designated for copying. The check mark can be input by, for example, pressing a one-segment key provided on the remote controller 121. When no check mark is input, a copy of only a 12-segment recorded program is designated.

  From the display state of the remaining number of times in FIG. 3 (c), the user confirms that copying of each of 12 segments and 1 segment is possible, and when selecting a copy of 1 segment program, after checking, When the enter key or the like is pressed, the dialog shown in FIG. 3C disappears, and the process returns to the display of the recorded program list list with the submenu display shown in FIG. Here, by operating the cursor key of the remote controller 121 to move the cursor in the thick line frame of the submenu display downward, selecting “copy” and pressing the enter key, the output destination (as shown in FIG. Move to the copy destination) specification screen.

  As an output destination, removable media connected to the digital broadcast receiving apparatus via the removable media medium I / F unit 113 and connected to the main body of the receiving apparatus, or the digital broadcast receiving apparatus via a network (for example, IEEE 1394). By selecting the copy destination from the externally connected HDD recorder or D-VHS recorder with the cursor key of the remote controller 121 and pressing the enter key, the desired program can be selected in the desired hierarchy (12-segment or 1-segment hierarchy). ) Can be copied to an external recording medium. However, the 12-segment or 1-segment layer can be selected because the 12-segment program and the 1-segment program are recorded in the receiver main body in advance as shown in FIGS. 3 (a) and 3 (b). It must be recorded on the medium.

Further, management information for copy control such as the number of times of copying from a recording medium in the receiving apparatus main body to an external recording medium including removable media connectable to the receiving apparatus main body is separated for each 12-segment program and 1-segment program. The number of times is managed by storing the file in the management information storage unit 111 as a file.
As a result, the copy control management data such as the number of times of copying is managed in a separate file for 12 seg and 1 seg in the digital broadcast receiving apparatus main body. The number of copies per segment can be easily managed.

According to the third embodiment of the present invention, for a recorded program recorded on a recording medium in the receiving apparatus body, either a 12-segment program or a 1-segment program is designated, and the program is designated as a removable medium. Can be copied or moved.
If the same program is recorded in the receiving device main body in both 12-segment and 1-segment, if the recordable capacity of the removable media selected as the copy destination is sufficient, the information volume is large and the high-quality 12-segment program If the recordable capacity is small, a 1-segment program with a small amount of information can be designated and copied or moved. In addition, by managing the number of copies separately for 12 segments and 1 segment, it is possible to count whether the number of copies is within the limit count or not and display it to the user separately for 12 segments and 1 segment.

  In the configuration of FIG. 1 according to the embodiment of the present invention described above, hierarchical transmission is performed in the tuner unit 102 instead of the receiving unit configured in the tuner unit 102 and the sorting unit configured in the control unit 114. A first tuner unit that receives a 12-segment program transmitted on a weak layer from a digital broadcast signal including a plurality of layers, and a second tuner unit that receives a 1-segment program transmitted on a strong layer from the digital broadcast signal. The 12-segment program and the 1-segment program are output separately from the first and second tuner sections, respectively, so that the 12-segment program and the 1-segment program are output separately. Good.

  In the embodiments described above, the digital broadcast receiving apparatus for fixed reception has been described. However, the present invention can be applied to a digital broadcast receiving apparatus for mobile / mobile reception.
