If you play the virtual title, you will not have to see any wasted video. Furthermore, the series program can be edited only once.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of the configuration of a recording / reproducing apparatus according to an embodiment of the present invention. First, each element constituting the recording / reproducing apparatus shown in FIG. 1 will be described.

  The digital interface (I / F) 1 is suitable for inputting / outputting digital data such as video and audio, such as IEEE 1394, PCI (Peripheral Component Interconnect), IDE (Integrated Device Electronics), SCSI (Small Computer System Interface), PCMCIA (Personal Computer Memory Card International Association) bus, USB (Universal Serial Bus) and other interfaces.

  The digital tuner unit 2 receives digital broadcast waves such as satellite digital broadcast and terrestrial digital broadcast by a receiving antenna (not shown), performs processing such as amplification, digital demodulation and error correction on the received signal, and demodulates the stream. . This stream includes video and audio information, and is a transport stream defined in, for example, MPEG-2 (Moving Picture Experts Group-2) Systems (ISO / IEC13818-1). Hereinafter, a stream including video and audio information is simply referred to as a stream.

  A stream input via the digital interface 1 or a stream demodulated by the digital tuner unit 2 is input to the MUX / DMX 3.

  MUX / DMX3 is a multiplexer and a demultiplexer. The multiplexer multiplexes the compression-encoded video signal, the compression-encoded audio signal, and the system data to generate a stream. The demultiplexer separates the compression-coded video signal, the compression-coded audio signal, and the system data from the stream.

  The stream generated by the multiplexer is input to the storage device 4 via the digital interface 1 or the stream control device 5. The video signal and audio signal separated by the demultiplexer are input to the digital video decoder 14 and the digital audio decoder 15, respectively.

  The storage device 4 is a device such as a hard disk drive, a DVD drive, or a BD drive suitable for recording and reproducing a stream on a recording medium. The stream control device 5 includes an interface such as IDE and controls the storage device 4. The stream control device 5 controls the storage device 4 to write the input stream at the time of recording, and controls the storage device 4 to read the recorded stream at the time of reproduction.

  The terrestrial tuner unit 6 receives an analog broadcast wave such as terrestrial analog television broadcast by a receiving antenna (not shown), performs amplification processing on the received signal, and analog television such as NTSC (National Television System Committee) system. A signal is acquired, an audio signal is separated from the acquired analog television signal, and an analog video signal and an analog audio signal are acquired. The analog television signal may be other than the NTSC system such as PAL (Phase Alternation by Line) and SECAM (Sequential Couleur a Memoire).

  The video signal and the audio signal acquired by the terrestrial tuner unit 2 are input to the analog video decoder 8 and the audio A / D converter 9 via the input switching circuit 7, respectively. The input switching circuit 7 switches between the output of the terrestrial tuner 6 and an external input via an external analog input terminal (not shown).

  The analog video decoder 8 decodes the composite color video signal input from the input switching circuit 7, separates the analog video signal, digitizes the separated video signal, and generates a digital video signal. The audio A / D converter 9 digitizes the analog audio signal input from the input switching circuit 7 and generates a digital audio signal. The digital video signal generated by the analog video decoder 8 is input to the video comparator 10.

  The video comparator 10 detects an editing point by comparing the digital video signal input from the analog video decoder 8 or the digital video decoder 14 with the video feature point data input from the RAM 20 or ROM 21. The voice comparator 11 detects an editing point by comparing the digital voice signal input from the voice A / D converter 9 or the digital audio decoder 15 with the voice feature point data input from the RAM 20 or ROM 21. . Information on the edit points detected by the video comparator 10 and the audio comparator 11 is stored in the RAM 20 via the bus 18.

  The digital video signal processed by the video comparator 10 is input to the digital video encoder 12 or the analog video encoder 16. During the recording operation, the input digital video signal is input to the digital video encoder 12 as it is. In the reproduction operation, if the edited digital video signal is not reproduced, the input digital video signal is directly input to the analog video encoder 16 or the digital video encoder 12, and if the edited digital video signal is reproduced, the edited digital video signal is converted to the analog video encoder 16. Alternatively, it is input to the digital video encoder 12.

  The digital audio signal processed by the audio comparator 11 is input to the digital audio encoder 13 or the audio D / A converter 17. During the recording operation, the input digital audio signal is input to the digital audio encoder 13 as it is. At the time of reproduction operation, when editing and not reproducing, the input digital audio signal is directly input to the audio D / A converter 17 or the digital audio encoder 16, and when edited and reproduced, the edited digital audio signal is audio. The signal is input to the D / A converter 17 or the digital audio encoder 13.

  The digital video encoder 12 subjects the digital video signal input from the video comparator 10 to compression coding processing such as MPEG-2. The digital audio encoder 13 subjects the digital audio signal input from the audio comparator 11 to compression encoding processing such as MPEG-2 AAC (Advanced Audio Coding). The video signal and audio signal compressed and encoded by the digital video encoder 12 and the digital audio encoder 13 are input to a multiplexer of MUX / DMX3.

  The digital video decoder 14 decodes a video signal compressed and encoded by MPEG-2 or the like input from a MUX / DMX3 demultiplexer. The digital audio decoder 15 decodes an audio signal that has been compression-encoded by MPEG-2 AAC or the like input from the MUX / DMX3 demultiplexer. At this time, the digital video decoder 14 and the digital audio decoder 15 supply time information of the stream being processed to the CPU 19 via the bus 18. The digital video signal and digital audio signal decoded by the digital video decoder 14 and the digital audio decoder 15 are input to the video comparator 10 and the audio comparator 11, respectively.

  The analog video encoder 16 converts the digital video signal input from the video comparator 10 into an analog video signal. The audio D / A converter 17 converts the digital audio signal input from the audio comparator 11 into an analog signal and generates an analog audio signal. The analog video signal converted by the analog video encoder 16 is output to the outside of the recording / reproducing apparatus via a video output terminal (not shown). The analog audio signal converted by the audio D / A converter 17 is output to the outside of the recording / reproducing apparatus via an audio output terminal (not shown).

  The bus 18 is a memory bus that connects the CPU 19 and memories such as the RAM 20 and the ROM 21. The bus 18 is further connected to a video comparator 10, an audio comparator 11, a digital video decoder 14, a digital audio decoder 15, and the like.

  The CPU 19 controls input / output of data to / from memories such as the RAM 20 and the ROM 21 and controls each element constituting the recording / reproducing apparatus. For example, the CPU 19 manages time information such as PTS (Presentation Time Stamp), and performs processing timing control in each element. Further, the CPU 19 executes a program stored in a memory such as the RAM 20 or the ROM 21.

  The RAM 20 is a writable semiconductor element that stores temporary data, and is, for example, an SDRAM (Synchronous Dynamic Random Access Memory). The ROM 21 is a read-only semiconductor element that stores various programs and data that do not need to be rewritten and are used in the recording / reproducing apparatus.

  This recording / playback apparatus can be edited by using a user interface such as a remote commander attached to the recording / playback apparatus while confirming the playback content when the program is played back by the program stored in the ROM 21. Furthermore, the program data of the scene set at the editing point (IN point OUT point) obtained by the editing can be acquired as feature point data and stored in the RAM 20.

  As the feature point data, video feature point data and audio feature point data are used. The video feature point data is video data of a program that can be identified as a match or a mismatch by comparing the digital video signal input to the video comparator 10 with the video feature point data. The video feature point data is composed of digital image data in units of frames, for example. The video feature point data may be partial image data within one frame. The video feature point data may be image data of a plurality of frames. Furthermore, the video feature point data may be image data such as a specific telop or caption. The video feature point data includes video data, identification information, and additional information such as time information indicating the position, and is managed so that the program and the position in the program can be identified.

  The audio feature point data is audio data of a program that can be compared with the digital audio signal input to the audio comparator 11 and the audio feature point data, and can identify a match or mismatch. The audio feature point data is, for example, digital audio data for a predetermined time that can identify audio. The audio feature point data includes audio data and additional information such as identification information and position information, and is managed so that the program and the position in the program can be identified.

  In the configuration shown in FIG. 1, two video feature point data and audio feature point data are used, but only video feature point data may be used. In the detailed description to be described later, the comparison using video feature point data will be mainly described.

  The method for acquiring the feature point data is not particularly limited, and a program having a fixed pattern can be acquired from outside the recording / reproducing apparatus and stored in the RAM 20 in advance. A fixed pattern is a video / audio pattern that is regularly broadcast at the start or end of the same program, immediately before a commercial, or the like. If rewriting is not necessary, the feature point data may be stored in the ROM 21 in advance.

  For example, the feature point data is connected to a server on the network via a network interface (not shown), acquired by downloading from the connected server, or from a removable recording medium such as a memory card connected to the digital interface 1. Or you can get it. Furthermore, the feature point data can be included in the broadcast wave together with the electronic program guide data, and the feature point data can be extracted from the broadcast wave received by the recording / reproducing apparatus.

  Here, operations during recording and reproduction by the recording / reproducing apparatus will be described. When a stream input to the digital tuner 2 or the digital interface 1 is recorded, the stream demodulated by the digital tuner 2 or the stream input via the digital interface 1 is supplied to the demultiplexer of the MUX / DMX 3 and separated. .

  The video signal separated by the demultiplexer of MUX / DMX3 is supplied to the multiplexer of MUX / DMX3 via the digital video decoder 14, the video comparator 10, and the digital video encoder 12. The audio signal separated by the MUX / DMX 3 demultiplexer is supplied to the MUX / DMX 3 multiplexer via the digital audio decoder 15, the audio comparator 11, and the digital audio encoder 13. The multiplexer of MUX / DMX3 generates a stream by multiplexing. The generated stream is recorded in the storage device 4 via the stream control device 5.

  When the comparison processing by the video comparator 10 and the audio comparator 11 is not performed, the stream demodulated by the digital tuner 2 is recorded as it is in the storage device 4 via the MUX / DMX 3 and the stream control device 5. Is done.

  When recording an analog television signal input from the terrestrial tuner 6 or an external input to the input switching circuit 7, the video signal is transmitted through the analog video decoder 8, the video comparator 10, and the digital video encoder 12 to the MUX / DMX 3. The audio signal is supplied to the multiplexer of MUX / DMX 3 via the audio A / D converter 9, the audio comparator 11, and the digital audio encoder 13. The multiplexer of MUX / DMX3 generates a stream by multiplexing. The generated stream is recorded in the storage device 4 via the stream control device 5.

  When the stream recorded in the storage device 4 is reproduced, the stream recorded in the storage device 4 is supplied to the demultiplexer of the MUX / DMX 3 via the stream control device 5 and separated.

  The video signal separated by the MUX / DMX 3 demultiplexer is output to the outside of the recording / reproducing apparatus via the digital video decoder 14, the video comparator 10, and the analog video encoder 16. The audio signal separated by the MUX / DMX3 demultiplexer is output to the outside of the recording / reproducing apparatus via the digital audio decoder 15, the audio comparator 11, and the audio A / D converter 17.

  When a playback signal is output from the digital interface 1, the video signal separated by the MUX / DMX 3 demultiplexer is passed through the digital video decoder 14, the video comparator 10, and the digital video encoder 12, and then the MUX / DMX 3. To the multiplexer. The audio signal separated by the MUX / DMX 3 demultiplexer is supplied to the MUX / DMX 3 multiplexer via the digital audio decoder 15, the audio comparator 11, and the digital audio encoder 13. The multiplexer of MUX / DMX3 generates a stream by multiplexing. The generated stream is output to the outside of the recording / reproducing apparatus via the digital interface 1.

  When the comparison processing in the video comparator 10 and the audio comparator 11 is not performed, the stream recorded in the storage device 4 is output as it is via the stream control device 5, the MUX / DMX 3, and the digital interface 1. The

  In this recording / reproducing apparatus, a title to be recorded or reproduced can be automatically edited based on information of editing points detected by the video comparator 10 and the audio comparator 11 by a program stored in the ROM 21. it can. The title is a unit indicating a stream in editing. For example, when the title of the stream A and the title of the stream B are combined by editing, a new title C is created. In order to automatically edit, feature point data corresponding to a program being recorded or reproduced needs to be stored in the RAM 20 or ROM 21 in advance. Whether or not the editing is automatically performed can be set as desired by the user. Hereinafter, editing of a title by the recording / reproducing apparatus will be described in detail.

  This recording / reproducing apparatus creates a virtual title from edit points detected by the video comparator 10 and / or the audio comparator 11 without directly editing the real title being recorded or reproduced. A real title refers to a title that has a one-to-one time correspondence with a main stream, and a virtual title refers to a title with only time information indicating the position of the main stream. The recording / reproducing apparatus supplies the created video signal and audio signal based on the virtual title from the video comparator 10 to the analog video encoder 16 and from the audio comparator 11 to the audio D / A converter 17, respectively. The audio signal can be reproduced.

  Here, creation of a virtual title will be described. Most programs such as news and dramas often have a fixed pattern at the beginning and end of the program. First, on the assumption that the video data of these fixed patterns is stored in the RAM 20 in advance, the creation of a virtual title in which the part before the start position of the program and the part after the end position are deleted will be described with reference to FIG. I will explain.

  FIG. 2A shows a title being recorded or reproduced (real title), and FIG. 2B shows a virtual title created by editing. Reference numerals 31 and 32 indicate fixed patterns of video at the start and end positions of the program, respectively. Reference numerals 33 to 36 are patterns of video feature point data as comparison sources stored in the RAM 20 described above. Note that the video feature point data 33 and 35 are stored in advance in the RAM 20 as the program head, and the video feature point data 34 and 36 are stored in the RAM 20 in advance as the program end.

  The video comparator 10 compares the video signal being recorded or reproduced with the video feature point data. That is, the digital video signal supplied from the analog video decoder 8 or the digital video decoder 14 is compared with the video feature point data supplied from the RAM 20.

  In the example shown in FIG. 2, video feature point data is stored for each program category such as “news program”, “drama”, and the category of the title being recorded or reproduced by electronic program guide data or the like is “news program”. When it is determined that the digital video signal is determined, the digital video signal and the video feature point data are compared. For example, it is possible to determine whether or not the digital video signal matches the video feature point data by comparing each other's image data in pixel units or by comparing each other's telop position information.

  When the video signal being recorded or reproduced matches the video feature point data by comparison, the video comparator 10 uses the matched portion as an editing point and adds additional information such as time information attached to the video feature point data. Based on this, edit the virtual title. In the example shown in FIG. 2, the video feature point data 33 and the video feature point data 34 coincide with the video signal being recorded or reproduced.

  If the editing point is at the beginning of the program due to time information or the like, the virtual title before the editing point is deleted. In the example illustrated in FIG. 2, for example, a portion before the time of the video feature point data 33 is deleted. If the edit point is at the end of the program due to time information or the like, the virtual title in the portion after the edit point is deleted. In the example illustrated in FIG. 2, for example, a portion before the time of the video feature point data 34 is deleted. As a result, a virtual title composed only of the entire news program is created, with the extra portions before and after being deleted. The deleted part is not limited to before and after the program, but may be in the middle of the program such as a commercial part.

  Next, a case where the next and subsequent titles are automatically edited using the first editing information in the series program will be described with reference to FIG. Reference numerals 41 to 45 denote images of program image data. Reference numerals 46 to 50 are video feature point data as comparison sources stored in the RAM 20.

  FIG. 3A shows a series program title (hereinafter referred to as a series title) recorded for the first time. It should be noted that the portion marked “deletion” is a portion to be deleted such as before and after the program or commercial. The user edits the title shown in FIG. 3A and creates a series title shown in FIG. 3B from which the part to be deleted is removed. At this time, a feature point of a part of the extracted title (hereinafter referred to as an item) is determined, and feature point data at the feature point is stored in the RAM 20.

  As the feature point of item # 1, the image data 41 at the head of the item is registered. At the end of the item, the feature time data is not registered, but the item time α is registered. As the feature point of item # 3, the top image data 43 and the end image data 44 of the item are registered as feature point data. Item # 2 registers the image data 42 at the head of the item as feature point data, and the item time β is registered at the end of the item. Item # 4 registers the image data 45 at the head of the item as feature point data, and the end of the item registers the item time γ.

  In this way, not only feature point data but also feature point data and time information are combined to determine the beginning and end of an item, so even if there is no clear feature point, the edit point can be identified it can. In this example, item time α determines the end of item # 1, item time β determines the end of item # 2, and item time γ determines the end of item # 4.

  The image data 41 to 45 and the item times α, β, and γ as the feature point data are stored in the RAM 20. The image data 41 to 45 are registered on the RAM 20 as feature point data 46 to 50, respectively.

  FIG. 3C shows a real title being recorded or reproduced after the second series. During the recording of the real title for the second and subsequent times in the series, the video data being recorded and the video feature point data stored in the RAM 20 are compared by the video comparator 10, and if they match, the editing point is determined. As detected, detection information such as coincidence information and time information is supplied from the video comparator 10 to the RAM 20. The virtual title is edited based on the detection information stored in the RAM 20 and the additional information of the feature point data stored in the RAM 20.

  In the example shown in FIG. 3, when the video data being recorded or reproduced matches the head image data (feature point data 46) of item # 1 stored in the RAM 20, the matching point is edited as a virtual title. Points. Since information attached to the feature point data 46 includes the item time α, the point advanced by the item time α from the editing point is set as the editing point at the end of the item # 1. A cutout between these two edit points from the virtual title shown in FIG. 3C is referred to as item # 1.

  Similarly, item # 2 to item # 4 are created, and the four created items # 1 to # 4 are combined. Thereby, the virtual title shown in FIG. 3D is created. Thus, in this recording / reproducing apparatus, the virtual titles of the second and subsequent series programs can be automatically created by the editing method in accordance with the first rule.

  By using a virtual title, it is possible to reproduce the automatically edited content while leaving the real title. In series programs, if feature point data and its additional information are registered in the first editing, a virtual title is automatically created based on the information from the next time. The virtual title may be further edited when there is a non-optimal part after the next time.

  When the title being recorded or reproduced is edited to create a virtual title and playback is performed using the created virtual title, the CPU 19 outputs the video title from the video comparator 10 and the audio comparator 11 according to the time information of the virtual title. Control digital video signals and digital audio signals. This control may be performed on the digital video decoder 14 and the digital audio decoder 15, the stream control device 5, or the storage device 4.

  As described above, according to the recording / reproducing apparatus of this embodiment, video feature point data of a program is acquired and stored in a memory such as the RAM 20, and the stored video feature point data and the program being recorded or reproduced are recorded. By comparing the video data with the video comparator 10 and using the point where the two match as a result of the comparison as an edit point, and creating a virtual title from the information of the edit point, even if there is a change in the broadcast time, etc. Can be recorded without omission, and unnecessary portions before, after and during the program to be recorded can be deleted by the virtual title. By storing in advance a feature point data of a scene desired to be an edit point in a memory such as the RAM 20, a desired edit can be automatically performed.

  Also, the audio feature point data of the program is acquired and stored in a memory such as the RAM 20, and the stored audio feature point data and the audio data of the program being recorded or reproduced are compared by the audio comparator 11, and both are compared. By making a matching point as an editing point and creating a virtual title from the editing point information, the program to be recorded can be recorded without omission even if there is a change in the broadcast time, etc., and the program to be recorded by the virtual title Unnecessary parts before and after or in the middle can be deleted. By storing in advance a feature point data of a scene desired to be an edit point in a memory such as the RAM 20, a desired edit can be automatically performed.

  Since the virtual title is used without directly editing the real title, even if the editing point is erroneously detected by the video comparator 10 or the audio comparator 11, the original state can be restored. That is, editing can be performed safely.

  The present invention is not limited to the above-described embodiments of the present invention, and various modifications and applications are possible without departing from the spirit of the present invention. For example, the configuration of the video and audio data input / output unit of the recording / reproducing apparatus described above is not particularly limited. For example, in the case of a recording / reproducing apparatus built in a television receiver, the video signal and the audio signal May be directly output to an output device such as a display.

  In the recording / reproducing apparatus according to the above-described embodiment, editing is performed using a program stored in the ROM 21. However, the editing program is recorded on a removable recording medium such as a DVD or a memory card. The installed version may be installed and stored in the RAM 20 or the hard disk. The editing program may be downloaded from a predetermined server via a network and stored in the RAM 20 or a hard disk. The processing performed by the editing program may be realized by hardware.

It is a block diagram which shows an example of a structure of the recording / reproducing apparatus by one Embodiment of this invention. It is a figure for demonstrating creation of a virtual title. It is a figure for demonstrating edit of a series title.
