Description

  The present invention relates to a digital broadcast recording / reproducing apparatus that receives a broadcast wave and records a program.

  For example, in a digital broadcast receiving system using a satellite, a video / audio signal is compressed using a digital signal compression technique, and a stream (transport stream) in which video / audio digital signals of a plurality of programs are time-division multiplexed is used as a transponder. Broadcasts via (satellite repeater). On the other hand, a broadcast receiving apparatus that receives such a digital broadcast selects one of a plurality of digital broadcast transponders received through an antenna by a tuner and selects one of a plurality of channels included in the one transponder. Is selected by a demultiplexing process, and a video / audio signal is output by decoding the digital signal of the selected channel.

By the way, conventionally, when a reserved program is started, a reserved channel is automatically set to record the received program. In the broadcast receiving apparatus that receives the digital broadcast described above, the program information superimposed on the digital broadcast wave is compared with the keyword input in advance by the user, and the program including the keyword in the program information is automatically selected. However, automatic recording is possible (see Patent Document 1).

Such a digital broadcast recording / reproducing apparatus may be configured to reproduce a recorded program when an operation for indicating reproduction permission is performed on the display of the message by the user.

  According to the present invention, even when the number of recorded programs (recorded programs) increases, it becomes easy to determine which program should be viewed preferentially. There is no worry that friends and acquaintances are out of sync with topics related to broadcast programs. There are various effects such as eliminating the worry of inadvertently missing a broadcast program that should be viewed in real time only by watching a recorded program (recorded program).

  A digital broadcast recording / reproducing apparatus according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 4. Here, a case where a BS (Broadcasting Satellite) digital broadcast is viewed will be described as an example.

  The antenna 1 is disposed outdoors in a predetermined direction, and receives a digital broadcast wave transmitted from the BS. The antenna 1 generally includes a frequency converter, and supplies a received / frequency converted signal to the tuner 2.

  The tuner 2 extracts a signal having a specific frequency from the received high frequency digital modulation signal. That is, a process of selecting one from a plurality of transponders of digital broadcasting is performed. Further, the tuner 2 includes a demodulation circuit, a deinterleave circuit, an error correction circuit, and the like, thereby demodulating the selected digital modulation signal and outputting a transport stream.

  The switch 5 selects and outputs either the transport stream output from the tuner 2 or the transport stream output from the stream recording / reproducing unit 4 according to a command from the system controller 17.

  The stream recording / playback unit 4 records the transport stream output from the tuner 2 on an HDD (hard disk drive) recorder 6 based on a command from the system controller 17. Further, the stream recording / reproducing unit 4 reads out the transport stream of the program instructed to be reproduced from the system controller 17 and supplies it to the switch 5.

  The demultiplexer (DEMUX) 3 separates the transport stream obtained via the switch 5 into a moving picture experts group 2 (MPEG2) video stream, an audio stream, and a program specific information / service information (PSI / SI). The stream and the audio stream are supplied to the AV decoder 7, and the PSI / SI is supplied to the system controller 17. Note that a plurality of channels are multiplexed in the transport stream, and the process for selecting an arbitrary channel from among the channels is performed by selecting which packet ID (PID) in the transport stream from the PSI / SI. ) Can be obtained by taking out data such as whether it has been multiplexed. Further, the selection of a transport stream (selection of a transbonder) can be performed based on PSI / SI information. Further, the SI includes program information (program content, program start time, program duration, genre code, etc.).

  The AV decoder 7 includes a video decoder that decodes a video stream and an audio decoder that decodes an audio stream. The video decoder decodes the input variable length code to obtain a quantization coefficient and a motion vector, and performs inverse DCT transform, motion compensation control based on the motion vector, and the like. The audio decoder decodes the input encoded signal to generate audio data.

  The video processing circuit 8 receives video data from the AV decoder 7 and performs D / A conversion, for example, to convert it into a composite signal in the NTSC format. The audio signal processing circuit 9 receives the audio data output from the AV decoder 7 and performs D / A conversion to generate, for example, a right (R) sound analog signal and a left (L) sound analog signal.

  The video output circuit 10 and the audio output circuit 11 include an output resistor, an amplifier, and the like. The AV output terminal 12 is provided with an output unit (a set of left and right audio output terminals and a video output terminal), and a monitor 14 having a display and a speaker is connected to the output unit by a video / audio code 13. .

  The OSD (on-screen display) circuit 19 outputs bitmap data based on character information and color information instructed to be output from the system controller 17 to the adder 20. The adder 20 performs processing for incorporating a video based on the bitmap data into the received video. The OSD circuit 19 implements EPG (Electronic Program Guide) screen display, menu screen display, list display regarding recording processing, and the like based on SI received by the system controller 17.

  The remote control transmitter 15 is a transmitter for sending a command to the broadcast receiving apparatus 30. When a key provided on the remote control transmitter 15 is operated, signal light (remote control signal) indicating a command corresponding to the key is transmitted from a light emitting unit (not shown). The remote control light receiver 16 receives the signal light output when the key of the remote control transmitter 15 is operated, converts it into an electric signal, and gives it to the system controller 17.

  A memory (eg, RAM, ROM, flash memory, EEPROM, etc.) 18 has program information (program content, program start time, program duration, genre information, etc.), recording reservation information, keywords, etc. Keyword priorities and the like are stored by processing of the system controller 17.

  The card IF (interface) 21 reads information from the loaded external card 22 based on an instruction from the system controller 17, and gives this information to the system controller 17. The system controller 17 stores the information in the memory 18 when the information is a keyword and a priority for the keyword. Further, the card IF (interface) 21 writes the keyword read from the memory 18 and the priority thereof in the external card 22 loaded based on an instruction from the system controller 17.

  Next, program recording control and related control by the system controller 17 will be described.

  When registering the keyword, the user uses the remote control transmitter 15 to instruct display of a menu screen, for example. When the system controller 17 receives a menu screen display instruction, the system controller 17 displays the menu screen using the OSD function. For example, an item such as “keyword registration” is provided on the menu screen. When this item is selected and determined by operating the remote control transmitter 15, the system controller 17 receives the determination and uses the OSD function to register the keyword. The keyword registration screen (for example, keyword list) is displayed.

  The user operates the arrow key (cross key) of the remote control transmitter 15 to move the cursor to a desired keyword location on the registration screen, and presses the enter key. The system controller 17 registers the keyword where the determination key is pressed in the memory 18.

  The system controller 17 searches for program information stored in the memory 18 and periodically searches for programs related to the registered keyword (for example, programs including the keyword in the program name or program content), and the program is detected. If it is, the broadcast start time and the like are written in the memory 18 as reserved program information. Further, the system controller 17 performs processing for sequentially reading reserved program information to be executed next written in the memory 18 and monitors the time. When determining that the broadcast start time of the reserved program has arrived, the system controller 17 gives tuning information to the tuner 2 and instructs the stream recording / playback unit 4 to record the transport stream. The stream recording / reproducing unit 4 outputs an HDD control signal to the HDD recorder 6 to record the received stream.

  As described above, programs related to a plurality of keywords registered by the user are automatically searched and recorded. Furthermore, the system controller 17 executes the following processing.

  (1) When inputting or changing the priority of a registered keyword, the user uses the remote control transmitter 15 to instruct display of a menu screen, for example. When the system controller 17 receives a menu screen display instruction, the system controller 17 displays the menu screen using the OSD function. For example, an item “list of registered keywords” is provided on the menu screen. When this item is selected and determined by operating the remote control transmitter 15, the system controller 17 reads the registered keyword from the memory 18 in response to the determination. The list screen is displayed using the OSD function. On this screen, a priority display frame is provided at the display location of each keyword. The user operates the arrow key (cross key) of the remote control transmitter 15 to move the cursor to the desired priority display frame on the screen, and for example, 0 to 100 (the larger the numerical value, the higher the priority). Enter a value up to a high degree) and press the Enter key. The system controller 17 registers the numerical value where the determination key is pressed in the memory 18 as the priority of the corresponding keyword. In addition, a rearrangement button is displayed on the screen, and when the system controller 17 detects that this button is pressed, the system controller 17 performs a process of rearranging the keywords in descending order of the priority values. Of course, the keywords may be arranged in descending order of priority in the registered keyword list regardless of the presence or absence of the rearrangement button or its operation.

  (2) When the system controller 17 detects the depression of the data output key provided on the remote control transmitter 15 or the receiver main body or the operation of the data output button on the menu screen, as described above, the system controller 17 performs the user registration. The read keyword and its priority (hereinafter referred to as a first information group) are read from the memory 18 and written to the external card 22. Further, when the system controller 17 detects that the data input key provided on the remote control transmitter 15 or the receiver body is pressed or the operation of the data input button on the menu screen is detected, the system controller 17 detects the external card 22 as described above. The external registration keyword and the priority (hereinafter referred to as the second information group) stored therein are read out and written into the memory 18. The external card 22 is a card deposited from a friend, for example, and the friend registers the registered keyword set in his / her receiver and the priority thereof in the external card 22. Therefore, in this case, the second information group can be said to be a friend-set keyword and its priority.

  (3) The user stores each of the first information group and the second information group in the memory 18 independently, or integrates and organizes the first information group and the second information group to give a new keyword and priority for it. It is possible to select whether to register the degree. For example, after writing the second information in the memory 18, the system controller 17 displays a message screen asking whether to perform individual registration or integrated registration using the OSD function. The user selects one using the remote control transmitter 15 or the like. When the individual registration is selected, the system controller 17 asks which one of the first information group and the second information group is selected, and always adopts the selected one thereafter. Alternatively, the system controller 17 asks which one of the first information group and the second information group is selected every time processing such as program reservation by a keyword, and adopts the selected one at that time.

  The integrated organization process includes a process in which overlapping keywords are combined into one. In this case, when the priorities are different, there is a process of adopting the priority of the user registered. Alternatively, when the priority on the second information group side is high, a process of adding a predetermined value (for example, 5 etc.) or a half value of the difference to the priority of the user registered (i.e., for setting a friend) It is also possible to perform processing that makes it somewhat close.

  (4) The rearrangement of (1) described above was performed when the registered keyword list was displayed. However, when displaying the list of recorded programs after recording (recorded program list), the order of program presentation is changed. You may make it determine based on the said priority. The recorded program list may include accompanying information such as program name, broadcast date and time, and broadcast station name. In addition, when displaying the recorded program list, in response to a program that has already been viewed by the user, a specific marking may be applied and a part of the accompanying information may be deleted and displayed. .

  (5) When a program playback by the HDD recorder 6 is requested by a user's operation, the recorded program list is normally displayed on the OSD and the program selected by the user is played back. When playback without designation is selected by the user, the system controller 17 selects and plays back the program with the highest priority value. If there are programs with the same priority, the program with the earlier broadcast date may be preferentially reproduced.

  (6) In the process (2) described above, information including priority is output / input, but in this embodiment, information without priority can also be output / input. That is, the system controller 17 performs a process for reading out only the external registration keyword stored in the external card 22 and writing it in the memory 18. Further, the system controller 17 performs processing for reading out only the keyword registered by the user from the memory 18 and writing it in the external card 22.

  (7) In this embodiment, when the program selected by the user is reproduced or when the program automatically selected by the system controller 17 is reproduced, the system controller 17 uses the accompanying information of the program to be reproduced. The program duration is acquired, and the playback completion time is calculated. Further, whether or not a program related to the keyword is broadcast between the current time and the playback completion time is determined based on, for example, acquired program information, recording reservation information, or the like. When it is determined that there is a broadcast program, as shown in FIG. 2, a message indicating that the program related to the keyword is broadcast within the playback time of the recorded program is displayed in OSD. The recorded program may be played back when the “Yes” button among the “Yes” and “No” buttons displayed on this screen is operated. Also, as shown in FIG. 3, a “program information display” button is displayed on this message screen, and when this button is operated, as shown in FIG. 4, it is broadcast during the playback time. Display program information.
