Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video data recording / reproducing method and apparatus for recording a program stream obtained by encoding program data including video data and audio data on a recording medium.

[0002]

2. Description of the Related Art Since video information has an enormous amount of information, its handling has conventionally been very difficult. However, recent developments in image coding and compression technology have made it possible to reduce the amount of information while ensuring image quality comparable to the original image, thereby making it relatively easy to handle image signals. It has become possible. As a typical image compression encoding method, MPEG2 for a wide range of materials from a resolution of about a standard television picture to a resolution of about a high definition television (HDTV) picture is widely known. MPEG2 has become the mainstream of recent moving picture coding systems because of its high versatility.

On the other hand, recent advances in recording medium technology have been remarkable, such as the appearance of small-sized and large-capacity optical disks such as DVDs. By combining this DVD with the above-mentioned MPEG2 and other image compression / encoding technologies, the conventional C
Even though it is the same size as D, it is possible to store a whole high-quality movie on one optical disc, and the handling is greatly improved.

Until now, the mainstream was to sell or rent a read-only DVD that recorded a movie or broadcast video. However, in recent years, write-once D
Recordable DVDs such as VD-Rs and rewritable DVD-RAMs have appeared. Against this background, an environment has been set up so that ordinary users can easily record video information on an optical disk by using a home video data recording / reproducing device instead of a conventional VTR.

[0005]

The kind of content of the video information as a program actually distributed to the viewer is various, even if it is simply called video information. For example, a film for a theater film may be replaced with a form to be broadcast on a television, or may be a video film taken from the beginning. They can also be dramas, news videos, music programs, and animations. These various types of video information are often converted into an encoded stream by setting appropriate encoding parameters for each type. For example, encoding with an emphasis on image quality is performed by securing a sufficient encoding rate, or encoding is performed at a reduced encoding rate from the standpoint that it is sufficient if the contents can be grasped. The same applies to the accompanying audio information, including monaural audio,
In the case of a two-channel sound or a movie, for example, surround sound of more channels is used to express a sense of reality. In addition, the coding rate of voice coding is changed according to the usage, or digitized raw voice information that does not reduce the amount of information is recorded from the standpoint of sound quality. As described above, regarding encoding, it is widely performed to select an appropriate encoding parameter according to the type of content of target video information.

[0006] On the other hand, when reproducing and displaying a recorded program, it is necessary to change the settings of the reproducing apparatus and peripheral devices according to the type of the content of the program. For example, when a movie is played back and displayed, post-filter processing for removing noise is performed on the decoder output signal of the playback device as a unique process outside the coding standard, or the television monitor as the display device is switched to the cinema mode. And make it easier to see. In addition, the sound output is set to a surround mode, or the sound level of only the center channel is increased to make it easier to hear the dialogue. In the case of the reproduction of a news video, the TV monitor may be set to a normal video video display mode, or the audio output may be monaural so that unnecessary surround speakers are cut off to save power.

[0007] Changing the settings of the reproducing apparatus and the peripheral devices according to the type of the content of the program is a very complicated operation for many ordinary users. Therefore, when a different type of program is reproduced, it is desirable to have a mechanism for automatically changing the settings of the reproducing device and the peripheral devices according to the type of the content.

Are connected and used. Although the external processing units 111 are illustrated as functional blocks in FIG. 1 separately from the video display unit 112 and the audio output unit 113, the actual processing device is a video display unit. The same device may be configured in combination with at least one of the video output unit 112 and the audio output unit 113, or may exist as a separate device from the video display unit 112 and the audio output unit 113. Also,
Various built-in processing units 110 and various external processing units 111
Need not necessarily have both as shown in FIG. 1 and may have only one of them if they have similar functions. The video display unit 112 and the audio output unit 113 are provided by the control unit 101 to the various processing units 11.
The same device may be configured by combining with a video information recording / reproducing device configured with each block up to 0, and in that case, it may be integrated with the various processing units 110.

FIG. 2 is a flowchart showing a flow of processing of the video data recording / reproducing apparatus according to the embodiment of the present invention. First, an operation until the program data input to the video data recording / reproducing device in the present embodiment is recorded on a recording medium will be described.

The distributed program data 201 is input to the video data recording / reproducing apparatus of this embodiment (step 20).
1). At this time, if the program data 201 is data that has not been compression-encoded (Y in step 203), the switching unit 102 outputs the uncompressed program data 204 to the encoding unit 103 (step 205). ). If the program data 201 is a compression-encoded program stream (N in step 203), the switching unit 102
Converts the compressed program stream 205 into extended data /
Output to the user data extraction unit 104 (step 207).

Here, the distributed program data 201 is data that has not been compression-encoded (processing A), and the distributed program data 201 is an encoded stream that has been compression-encoded (processing B).
Is processed as follows.

When the distributed program data is data that has not been compression-encoded (process A), the data 204 is input to the encoding unit 103 by the switching operation of the switching unit 102 as described above. The encoding unit 103 performs an encoding process on various types of material information such as video, audio, and subpictures of the program data 204 that has not been compressed and encoded (step 209). Specific encoding processing, such as selection of various encoding parameters, is performed under the control of the control unit 101, and exchanges control signals from the control unit 101 and monitor information from the encoding unit 103 via a signal line 206. If the uncompressed program data 204 is analog data, A (not shown)
The data is converted into digital data by a / D converter and subjected to an encoding process. However, audio and sub-pictures having a small amount of information may only be digitized and not encoded, depending on the type of program data content and user settings. Encoded video / audio /
The coded stream 208 such as a sub-picture is output to the switching unit 105 (Step 211). The streams of the video, audio, sub-picture and the like may be multiplexed using a multiplexing unit (not shown) built in the encoding unit 103 and then output to the multiplexer 106, After being output to the multiplexer 106, the multiplexing of the video / audio / sub-picture may be performed at the same time as the setting information of the reproducing device and the peripheral device is multiplexed in the multiplexer 106 as will be described later.

In the case where the distributed program data is a compression-encoded stream (process B), the encoded stream 205 is switched to the switching unit 1 as described above.
02, the extended data / user data extraction unit 1
04 is input. The extended data / user data extraction unit 104 adds the encoded program stream 205 to the
It is determined whether or not additional data that can be used for generating setting information of the playback device and the peripheral device, for example, extension data or user data in the MPEG2 standard is attached, and if attached (Y in step 213), Is extracted and the control unit 10 is
1 (step 215). If it is not attached (N in step 213), the process returns to the beginning of process B. Also, the program stream 209 subjected to this extraction processing is
Output to the switching unit 105 (step 217). The operation of the extension data / user data extraction unit 104 is controlled by the control unit 1
01, and exchanges necessary information via the signal line 207.

The switching unit 105 cooperates with the switching unit 102 to change the program stream 2 input from the encoding unit 103.
08 and the program stream 209 input from the extension data / user data extraction unit 104, and
The signal is output to the multiplexer 106 through the step 11 (step 219).

Next, the control signal 202 by the operator may be input to the control unit 101. This control signal 202
Is a control signal in which the operator has set individual parameters of the setting information of the recording / reproducing device and the peripheral device, or a plurality of setting information prepared as a template in which various parameters are set in advance according to the type of the program. Or a selection signal that selects an appropriate one from the above.

Information 203 such as an electronic program guide input from outside may be input to the control unit 101. The control unit 101 receives these various control signals, that is, a control signal 202 by an operator, information 203 such as an electronic program guide input from the outside, an expansion data input from the expansion data / user data extraction unit 104, or Analyze user data (Step 22
1) Based on the result of the analysis, the setting information for the reproducing device and the peripheral device associated with each program stream to be recorded on the recording medium is generated (step 22).
3). The generated setting information 212 for the playback device and the peripheral device is output to the multiplexer (step 225).

The multiplexer 106 controls the program stream 211 input via the switching unit 105 and the control unit 10.
The setting information 212 for the reproducing device and the peripheral device associated with the individual program streams input from 1 is multiplexed (step 227), and the multiplexed data 213 can be detached from the video data recording / reproducing device of this embodiment. For example, the data is output and recorded on the recording medium 107 such as a DVD-RAM (step 229). It should be noted that, as described earlier in the description of the operation of the encoding unit 103, this multiplexer 10
At the time of multiplexing the setting information of the reproducing device and the peripheral device in 6, the multiplexing of the video / audio / sub-picture may be performed at the same time.

According to the above-described procedure, the program data distributed to the video data recording / reproducing apparatus in the present embodiment and the setting information for the reproducing apparatus and the peripheral device associated with each program data are stored in the DVD-ROM. It is recorded on a removable recording medium such as a RAM.

FIG. 3 is a flow chart showing a flow of processing for reproducing program data recorded on a removable recording medium such as a DVD-RAM. The recording medium 107 such as the DVD-RAM is mounted on the video data recording / reproducing apparatus according to the present embodiment. This video data recording / reproducing device does not need to be the same as the device used when recording the program data on the recording medium 107, as long as it has a function as shown in the block diagram of FIG. It may be a completely different device.

The demultiplexer 108 reads a stream 214 of program data to be reproduced and displayed from the recording medium 107 (step 301). As described above, the setting information for the playback device and the peripheral device associated with each program stream is multiplexed on this stream by the multiplexer 106 as described above. The demultiplexer 108 separates the multiplexed setting information for the reproducing device and the peripheral device from the program stream, and outputs the separated setting information 215 to the control unit 101 (step 303). The program stream 216 separated from the setting information is output to the decoding unit 109. In the demultiplexer 108, when the setting information for the playback device and the peripheral device is separated, the program stream may be separated into video, audio, and sub-picture streams at the same time and output to the decoding unit. The data may be output to the decoding unit in a format that is not separated into video, audio, and sub-picture.

In the decoding section 109, the demultiplexer 10
8 is decoded and converted into video / audio / sub-picture (step 307). Here, when a program stream is input from the demultiplexer 108 in a format in which video / audio / sub-pictures are multiplexed, the video / audio / sub-pictures are Separate into each stream. The specific decoding process is performed under the control of the control unit 101, and the control unit 101
And a monitor signal from the decoding unit 109 and the like. The decoded video / audio / sub-picture data 218 is output to the various processing units 110 built in the video data recording / reproducing apparatus of the present embodiment or to various external processing units 111 (step 309). ).

The control unit 101 analyzes the setting information of the reproducing device and the peripheral device, which have been separated and input from the program stream by the demultiplexer 108, and actually controls the reproducing device and the peripheral device based on the setting. (Step 311). Here, as the control information for actually controlling the peripheral device, for example, a remote control code corresponding to control of a television / video made by a plurality of manufacturers may be mentioned as an example, but it is not necessarily limited to this. It goes without saying that various types of control information may be used as long as they conform to the gist of the present invention. The control unit 101 converts the actual control signal 221 converted from the setting information of the reproducing device and the peripheral device into various processing units 110 built in the video data recording / reproducing device of the present embodiment or various external processing units 111 (Step 31)
3).

The various processing units 110 and the various external processing units 111 incorporated in the video data recording / reproducing apparatus according to the present embodiment correspond to the reproducing apparatus input from the control unit 101 and associated with the program data to be reproduced and displayed. And the video / audio / sub-picture data 21 input from the decoding unit 109 based on the control signal 221 for the peripheral device.
8 are subjected to various processes (step 315). Specific examples of these processes are as illustrated in FIG. 4, as will be described later. For example, there is a process of applying an outline emphasis filter to a video signal. Video data / sub-picture data 2 processed based on control information associated with such individual program data 2
19, 222 and audio data 220, 223 are output to the video display unit 112 and the audio output unit 113, respectively (step 317).

According to the procedure described above, for example, a DVD-R
Program data recorded on a removable recording medium such as an AM is reproduced and displayed. The outline of the operation of the video data recording / reproducing apparatus according to the embodiment of the present invention has been described above with reference to FIG. 1. However, the present invention is not limited to the embodiment of FIG. 1, and does not depart from the gist of the present invention. It goes without saying that various forms can be taken. For example, in the example of FIG. 1, a function of generating setting information for the playback device and the peripheral device and a function of converting the information into control information of the playback device and the peripheral device take a form in which the control unit 101 is built. However, at least one of these is
It may exist as an independent processing block separate from the one. Also, the extension data / user data extraction unit 104
Is described as an independent block as a functional block on the schematic configuration diagram, but this may be a function in the decoding unit 109 or the control unit 101, for example. The various processing units describe both the one built in the video data recording / reproducing apparatus of this embodiment numbered 110 and the external one numbered 111, but the functions are integrated. It may be either built-in or external.

In this embodiment, the operation of recording the setting information of the reproducing device and the peripheral device on the recording medium 107 in association with the individual program data is as described above.
This is not only performed when recording the distributed program data on a recording medium. The recording of the setting information of the reproducing device and the peripheral device performed at the time of recording the distributed program data can be regarded as a kind of initial setting. However, the recording of the setting information is not limited to only the initial setting. After the recording on the recording medium 107 is completed, the operator can make another setting change. In this case, the changed setting information of the reproducing device and the peripheral device should be recorded on the recording medium in association with the program data. It goes without saying that you can do it. Further, depending on the type of setting information for the reproducing device and the peripheral device, update information may be automatically recorded on the recording medium 107 in association with the reproducing operation of the program data. For example, as a setting for the control of the playback device, a “continuation playback” function for stopping playback in the middle and displaying the continuation again at a later date, and a “synopsis playback” function for playing back a digest of the portion that has been viewed before that together O
In the case of setting to N, since information on “how far has been played” is required in connection with this,
In the case of N, when the reproduction display of the program is stopped halfway, the operation of updating the information of “how far has been reproduced” and recording it on the recording medium 107 is automatically performed.

It should be noted that the setting information for the playback device and the peripheral device is not limited to being multiplexed in a narrow sense in the program stream, but is associated with the individual program data and managed on the recording medium 107. It may be recorded in the information area. For example, in the case of a DVD-RAM, the optional Manufacture's Information
A configuration may be adopted in which such setting information is recorded in the migration table, or pointer information to an area where the setting information is recorded is recorded.

When program data is distributed as a compression-encoded program stream, extended data and user data used for generating setting information of a reproducing apparatus and peripheral apparatuses are composed of video, audio, and sub-pictures. Video, audio, and sub-picture materials such as extension data and user data inserted into video data compressed and encoded by MPEG2, for example. It may be inserted into the encoded stream of data.

FIG. 4 shows an example of the setting information for the reproducing device and the peripheral device. However, these are merely examples, and it goes without saying that various other types of setting information can be obtained without departing from the gist of the present invention. These setting information is used by an operator manually setting parameters of each setting information.

FIG. 5 shows an example of the setting information of the recording / reproducing apparatus and the peripheral device as a template in which various parameters are set in advance according to the type of the program. However, this is merely an example, and it goes without saying that various other types of setting information can be obtained without departing from the gist of the present invention. In the example of FIG. 5, the settings are such that the following control is performed on the playback device and the peripheral devices.

For example, in the case of recording a normal TV drama, even if the reproduction is stopped in the middle for some reason, the "synopsis reproduction" function and the "continuous reproduction""It is set to use the function. In addition, the display which is a peripheral device is set to be switched to a display mode for displaying a normal television image.

When a movie is recorded, the "synopsis playback" function and the "continuous playback" function are set for the playback device as in the case of the previous TV drama, but the peripheral device is used. The display is set to switch to a mode suitable for displaying a movie screen shot with film. In addition to this, let the playback device set the sound surround output to output a powerful sound effect, and increase the volume of the center channel of the surround speaker when the actor is speaking in order to make it easier to hear the dialogue The settings are as follows. Further, in order to remove noise superimposed on the film image, the setting is such that a noise reduction function of the image is used. The functional blocks for performing the noise reduction of the video correspond to various processing units numbered 110 or 111 in the video data recording / reproducing apparatus in the example of FIG.

When a music program is recorded, the audio is set to stereo output, and the audio noise reduction function built in the reproducing apparatus or the external audio amplifier is used. Also, turn on / off the power supply to the speaker to the external audio amplifier device.
If the function to perform F is provided, the power to the surround speakers not used in the reproduction of the music program can be turned off to save power. The functional blocks for performing the audio noise reduction correspond to various processing units numbered as the video data recording / reproducing devices 110 or 111 in the example of FIG.

When recording news, the function of generating a headline screen by extracting the beginning of the news content at the time of reproduction is turned on for the reproducing apparatus, and a plurality of headline screens are displayed in parallel. It is set to turn on the multi-screen display function. Furthermore, the setting is such that the speech speed conversion reproduction function is turned on so that the voice can be reproduced at the normal speed while performing the fast forward reproduction so that the contents can be grasped in a short time.

As described above, the setting information of the recording / reproducing device and the peripheral device as a template in which various parameters are set according to the type of the program data is selected by an operator's selecting operation or externally. It is selected based on the input information such as the electronic program guide and is recorded on the recording medium in association with the individual program data. In addition,
It goes without saying that the individual parameters contained in these templates can be individually tuned by the operator. Also, depending on the preference of the operator,
Of course, it is also possible to create and use a template of the original setting information.

As described above, in the video data recording / reproducing apparatus of the present invention, when the operator sets individual parameters of the setting information of the recording / reproducing apparatus and the peripheral device, various parameters are set in advance according to the type of the program. A plurality of setting information as a template is prepared, and when selecting appropriate setting information by an operator's selection operation, a plurality of setting information as a template in which various parameters are set in advance according to the type of program are prepared, and from outside, When selecting appropriate setting information based on information such as the input electronic program guide, the contents of the extended data and user data inserted in the input program stream are analyzed, and based on the analyzed contents, When setting information for the recording / reproducing device and the peripheral device is set, all the settings are supported.
