Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to video and audio data used for recording program data including video data and audio data on a recording medium, reading the recorded program data from the recording medium, and reproducing and displaying the data. The present invention relates to a video / audio data recording management method in a recording / reproducing apparatus.

2. Description of the Related Art In the past, it was very difficult to handle video information having an enormous amount of information, but with the development of image coding and compression technology in recent years, while realizing image quality comparable to the original image, The amount of information can be greatly reduced, which makes it possible to handle video information relatively easily. MPEG2, a typical image coding and compression method, is used for a wide range of materials from the resolution of standard TV video to the resolution of high-definition TV (HDTV) video, and has been widely used in recent years due to its high versatility .

On the other hand, recording medium technology has been remarkably advanced in recent years, such as the development of a small-sized and large-capacity optical disk such as a DVD.

By combining this DVD with the above-mentioned MPEG2 and other image compression coding techniques, it is possible to record a whole high-quality movie on a small optical disk of the same size as an existing CD. And the ease of handling has greatly improved.

Conventionally, movie companies and broadcasting stations use large and expensive MPEG2 encoders to encode owned movies and broadcast programs and sell or rent those that are recorded on a read-only DVD. The shape was mainstream. However, in recent years, an MPEG2 encoder LSI realized with one chip has been developed, and it has become possible to reduce the size and cost of an encoding device. In addition to recordable DVDs, recordable DVDs such as DVD-RAMs have recently appeared. Against this background, an environment in which home video data recording / reproducing devices using optical disks, which replace conventional VTRs, are provided to general users is being prepared.

[0006]

As an example of usage of a home video data recording / reproducing apparatus by a general user, recording of video data supplied from the outside such as a broadcast program can be considered. Among the broadcast programs, there are not only programs that are broadcast only once but also continuous programs with some relevance. For example, the content of each broadcast is a continuous drama that completes the story with several to several tens of broadcasts, and the content of each broadcast is a single episode but common background and settings For example, a series program that is produced under the Internet. These series programs are often broadcast with a certain regularity over a certain period of time, such as being broadcast on the same day of the week on the same day, or on the same time every weekday. . For this reason, many proposals have been made regarding the realization of a simple scheduled recording operation utilizing the regularity of the broadcast date regarding the scheduled recording operation of these programs.

[0007] However, in reproducing and displaying a recorded program, it cannot be said that an approach taking into account that the program is a continuous program has been sufficiently performed.

[0008] For example, there is a portion that does not need to be reproduced and displayed every time. When viewing a recorded serial program, there is of course a form in which it is played back and displayed immediately each time it is recorded, for example.However, taking into account the continuity and relevance of the broadcast content of each time, several times are summarized. A form of watching is also conceivable. Here, when viewing a continuous program in the latter form, if the recorded program is simply reproduced and displayed sequentially, the opening roll, the ending roll, or the next trailer will be reproduced and displayed without the necessity of every time.

[0009] Another example is the display of a digest video. If a small and large-capacity optical disc such as a DVD-RAM is used as a recording medium, several programs can be generally recorded on one disc, depending on the length of the program. For such discs, it is convenient to have a mechanism that can play back and display a short digest video in order to check the recorded content. From the digest video, the corresponding main video can be easily operated. It is convenient to have a mechanism that can be called, but digest videos with appropriate contents,
It is difficult to prepare a mechanism for calling the main video from here each time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and realizes a playback / display method utilizing the properties of a recorded continuous program to improve the convenience of the user. The purpose is to provide a record management method.

[0021]

Embodiments of the present invention will be described below with reference to the drawings.

First, a small block in the present invention is assumed to be a data block describing a pointer to a part of video data. When a part of the video data is handled independently, a part of the video data may be actually cut directly, but since the amount of information of the video data is extremely large and the processing load of the circuit is large, a pointer is actually used. The virtual data block describing the information is handled by associating a part of the video data with the virtual data block. In order to access actual video data, pointer information described in a data block is traced.

In the following embodiment, the absolute time at which each part of the video data is recorded is used as the pointer information, but it goes without saying that the pointer information is not necessarily limited to this. For example, it may be a logical address or a physical address on a recording medium, or a time code. Regardless of address information or time information such as time or time code, they may be absolute values, or may be defined as a base point and be a relative value from the base point. Is also good. Alternatively, both may be used in combination. In short, it is such that a portion of the video data recorded as pointer information can correspond to a small block which is a virtual data block,
Furthermore, various information can be used as the pointer information as long as it is in accordance with the gist of the present invention.

The small block reproduction order rule is such that necessary small blocks to be reproduced and displayed are selected and registered in the display order.

Both the rule for associating each part of the video data with each small block and the reproduction order rule for registering a plurality of such small blocks may be held independently, but in practice, they are integrated. Such a configuration is presumed in the following embodiments, since it is considered that the configuration is often retained. Of course, they may exist independently for the purpose of the present invention.

When a DVD is used as a recording medium, a small block in the present invention corresponds to a cell in the DVD, and a reproduction order rule of the small block corresponds to a playlist.

FIG. 1 is a block diagram showing an example of a video / audio data recording / reproducing apparatus for realizing the video / audio data recording management method of the present invention. It is assumed that the apparatus exemplified here has a configuration including the following processing units.

The control unit 101 performs general control of the entire video / audio data recording / reproducing apparatus.
A process for setting and holding rules for associating partial portions of recorded video data with a plurality of separate small blocks, a process for setting and holding a reproduction order rule for a plurality of small blocks, and between small blocks recorded at different dates and times. In addition, various processes according to the present invention, such as a process of setting and holding an association rule, are performed.

The storage unit 102 stores a program for causing the control unit 101 to perform various processes according to the present invention. Although it is considered that a semiconductor memory is often used as the storage unit 102, a storage device such as a hard disk drive (HDD) may be used. Further, a combination of a semiconductor memory having a high access speed and an HDD having a large recording capacity may be used.

The recording medium 103 is, for example, a DVD-RAM
And a recordable medium such as an optical disk and a magneto-optical disk.

The user operation unit 104 sets a rule for associating a portion of the recorded video data with a plurality of small blocks, sets a reproduction order rule for the plurality of small blocks, and sets a rule between small blocks recorded at different dates and times. It is used by a user to set various rules according to his or her intention when manually setting an association rule or the like in the first round of a serial program. This is also a controller for performing general operations other than the operations related to the contents of the present invention in the video / audio data recording / reproducing apparatus. The user operation unit 104 is, for example, a remote control or a group of operation switches on a front panel of the video / audio data recording / reproducing apparatus.

The CM detecting section 105 is for checking the appearance time of the CM in the received program. As an example, when a current analog broadcast is received, an existing CM detection unit such as a detection unit for switching between stereo sound and monaural sound can be used as the CM detection unit 105.

[0033] Encoding section 106 receives the video of the received program.
The compression encoding process is performed on audio and sub-pictures.

The decoding section 107 expands the compressed coded stream to obtain signals such as video, audio, and sub-pictures.

For example, when receiving the current analog broadcast, the receiving device 108 corresponds to a television tuner or the like.

The display device 109 indicates a monitor screen for displaying video and sub-pictures, a speaker for outputting audio, and the like.

In the video / audio data recording / reproducing apparatus having the above-described configuration, the following operation is performed.

First, an operation for recording a received program on a recording medium will be described.

For example, the receiving device 108 such as a television tuner in the current analog broadcasting is connected to the signal line 133.
Based on a control signal sent from the control unit 101 via
The user selects and receives a program to be recorded from the program data 121 that can be input to the video / audio data recording / reproducing apparatus,
The target program data 122 is output to the encoding unit 106. The control unit 101 obtains, from the receiving device 108, information necessary for performing control via the signal line 133.

The encoding unit 106 controls the video / video of the program data 122 input from the receiving device 108 based on a control signal exchanged with the control unit 101 via a signal line 134.
A compression encoding process is performed on each of the audio and the sub-picture.
The encoded stream 123 that has been subjected to the compression encoding process
Is output to the recording medium 103 and recorded. At this time, recording is performed based on the rules of the recording format determined for each recording medium according to the type of the recording medium 103. Whether each of the encoded streams of video, audio, and sub-pictures is multiplexed and recorded or recorded without multiplexing also depends on rules determined by the type of the recording medium 103. Note that the control unit 101
Obtains information necessary for performing control via the signal line 134 from the encoding unit 106.

The control unit 101 is connected to the signal line 134.
Based on information obtained from the encoding unit 106 via the standard setting rule for associating each part of the video data with a plurality of separate small blocks, and a standard reproduction order rule of the plurality of small blocks, If necessary, rules for associating standard settings with small blocks recorded at different dates and times can be set. The program for performing the standard setting is stored in the storage unit 102, and the control unit 101 creates various rules of the standard setting based on the program read from the storage unit 102 via the signal line 124. The rules for these standard settings include:
For example, there is an example in which all the program data recorded on the recording medium 103 are displayed in the recording order without any editing processing. The various rules of these standard settings are defined and managed separately from the playback order rules and the like set by the user, which will be described later, so that the recorded contents can be reproduced and displayed as they are without performing any editing processing as necessary. Good. Alternatively, the information may be edited and processed as a hitting table when creating a reproduction order rule by a user described later. The various rules of the standard setting may or may not be set according to the standard determined by the type of the recording medium.

When various rules of the standard setting are set, the control section 101 records and holds this information. The recording location may be, for example, a management information area (not shown) on the recording medium 103 or a recordable area on the recording medium 103 other than the management information area. Further, for example, when a semiconductor memory or the like is mounted on a disk cartridge storing an optical disk or a magneto-optical disk as a recording medium, the information may be recorded there. In these cases, the various rules of the standard setting are recorded via the signal line 125 and held. Also, as a place for recording the various rules of the standard setting,
A recording unit provided on the video / audio data recording / reproducing device may be used. In this case, even if the data is recorded in a recording unit provided for storing a rule for associating a portion of video data with a plurality of small blocks, a reproduction order rule, and a rule for associating small blocks, which are not shown in FIG. Alternatively, the information may be recorded in the storage unit 102 of FIG. 1 via the signal line 126. Further, all of these various rules may be recorded in the same place, or at least one rule or all the rules may be recorded in different places. For example, the association rule for the small blocks and the reproduction order rule are collectively recorded in the management information area on the recording medium 103, and the association rules between the small blocks recorded at different dates and times are other areas,
In other words, the recording may be performed in a recordable area other than the management information area on the recording medium 103, in a semiconductor memory mounted on a disk cartridge, or in a recording unit on the apparatus main body.

In addition, the various rules of the standard setting described above are recorded with the same contents in a plurality of different locations as described above, and are used as backups in case of any failure in the main recording location. Is also possible.

In the case of recording on the recording medium 103 as described above, or in the case of recording on a semiconductor memory mounted on a disk cartridge for storing the recording medium, for example, the recording reservation information of the continuous program is also recorded on the recording medium. By recording together with 103 or a semiconductor memory mounted on a disk cartridge, a specific recording medium can be
It can be dedicated to recording a particular series. Of course, such a function may not be used if it is not necessary. In the case of recording in a recording unit (not shown) provided on the apparatus main body or the storage unit 102 in FIG. 1, a specific recording medium does not need to be dedicated to recording of a specific continuous program,
Alternatively, by using a means for individually recognizing each recording medium, the various rules of the standard setting held on the main body are associated with the specific recording medium, and the specific recording medium is dedicated to recording a specific continuous program. Can also.

Secondly, when recording the first episode of the continuous program, the rules for associating with the small blocks, the rules for the reproduction order, and the rules for associating between the small blocks are manually set by the user. The operation when the result is held will be described.

When setting the reproduction order rule and the like, it is generally considered that the recorded program is monitored and the setting operation is performed. Therefore, the user operates the user operation unit 104 to select a recorded program to be displayed on the monitor, or to select a normal forward / forward direction for the program.
Various playback display operations such as reverse playback, fast-forward / fast-reverse playback, and slow-forward / slow-reverse playback are executed as necessary, and these operation signals are transmitted to the control unit 1 via the signal line 130.
Enter 01.

The control unit 101 controls reproduction and display based on an operation signal input from the user operation unit 104 via the signal line 130. Specifically, the compressed encoded stream 128 recorded on the recording medium 103 is read and input to the decoding unit 107, and a control signal for reproduction display is output to the decoding unit 107 via the signal line 135. .
Note that the control unit 101 obtains, from the decoding unit 107, information necessary for performing control via the signal line 135.

The decoder 107 decodes the compressed coded stream 128 read from the recording medium 103 based on a control signal input from the controller 101 via a signal line 135.
Is extended. Also, based on the control signal, expanded video, audio, sub-picture, etc., so that the user can reproduce and display in a desired state such as normal speed forward / reverse playback, fast forward / fast reverse playback, slow forward / slow reverse playback, and the like. Is output to the display device 109.

The display device 109 displays the input image
A signal 129 such as audio / sub-picture is output to a monitor screen for video and sub-picture, and audio is output to an audio output device such as a speaker.

The control unit 101 can display various information for improving the user's convenience on a monitor screen or output the information from a speaker as necessary. For example, the time code of the screen, the type of picture (the type of I #, P #, B # picture in MPEG2) and the like can be displayed on the monitor screen. In addition, a warning message when an inappropriate operation is performed can be displayed on a monitor screen or output as a sound from a speaker.
In such a case, the information is directly sent from the control unit 101 to the display device 109 via a signal line not shown in FIG. 1 or output via the signal line 135 to appropriately bypass the inside of the decoding unit 107. Later, the data may be output to the display device 109 via the signal line 129. This portion can be freely configured as long as it is in accordance with the gist of the present invention.

By monitoring the recorded program reproduced and displayed according to the above-described procedure, the user operates the user operation unit 104 to associate an arbitrary portion of the video data with each of the small blocks. An operation of setting a reproduction order rule of a plurality of small blocks and an operation of setting an association between small blocks recorded at different dates and times are executed. An operation signal reflecting these operation contents is output to the control unit 101 via the signal line 130.

Based on the operation signal input from the user operation unit 104 via the signal line 130, the control unit 101 determines a rule for associating a portion of the video data with a plurality of separate small blocks, and a plurality of rules. The reproduction order rules of the small blocks and the association rules between the small blocks recorded at different dates and times are set. At this time, if necessary, an appropriate program is stored in the storage unit 1 via the signal line 124.
02 may be read. The setting of these various rules is described separately using a conceptual diagram, and will not be described in detail here.

The rules for associating with the small blocks, the reproduction order rules, and the associating rules set by the user are stored in the recording medium 103 in the same procedure as the various rules of the standard setting described in the first operation description. Recorded in a management information area or other recordable area, a semiconductor memory mounted on a disk cartridge, or a recording unit (not shown) provided in the main unit of the video / audio data recording / reproducing apparatus or the storage unit 102 in FIG. Will be maintained. Regarding the holding operation and the point that the specific recording medium related to the specific recording medium is dedicated to the recording of the specific continuous program, the content of the description of the various rules of the standard setting described above can be applied as it is, so it will not be described in detail here. I will.

Third, the association rule, the reproduction order rule, and the association rule set and held previously are read out, and the reproduction order rule and the small block interval for the next and subsequent times of the newly recorded continuous program are read out. The operation in the case of creating and holding the association rule of the above will be described.

First, the program data of the next and subsequent times of the target continuous program input to the video / audio data recording / reproducing apparatus is recorded. Here, it is generally assumed that an existing continuous program reservation recording method or the like is used. With respect to the recording operation of the input program, the processing in the receiving device 108 and the encoding unit 106 described above in the first operation description is performed, and the compressed encoded stream of the program is recorded on the recording medium 103. You. The operation up to the recording on the recording medium 103 is the same as that of the first operation described above, and will not be described in detail here.

Next, for example, by using the existing program reservation recording method or by setting by the user, "what day, what time, what time, what time, what minute, what channel are being broadcast, what time, etc. The identification of an individual serial program as to whether it is a "program" has been made. Therefore,
For a certain serial program, a rule for associating a portion of the video data, which is set and held in advance based on the number of broadcasts in the past, with each of a plurality of small blocks, and the plurality of small blocks. The rules for playing the blocks and the rules for associating the small blocks recorded at different dates and times can be easily specified. These various rules are based on the management information area on the recording medium 103 and other recordable areas, the semiconductor memory mounted on the disk cartridge, or the video / audio It is held by being recorded in a recording unit (not shown) provided in the main body of the data recording / reproducing apparatus or the storage unit 102 in FIG. Therefore, when reading these stored rules from the semiconductor memory mounted on the recording medium 103 or the disk cartridge, the signal line 127 is used, and when reading from the storage unit 102, the signal line 127 is used.
When reading 24 from a recording unit (not shown) provided on the apparatus, the control unit 101 reads 24 from the recording unit via an appropriate signal line.

The control unit 101 applies the various rules read out to newly recorded times of the continuous program, and associates the newly recorded times with small blocks, rules of reproduction order, and rules between small blocks. Create association rules for
At this time, if necessary, an appropriate program is
May be read from the storage unit 102 via the. Specific examples of the creation of these new rules have been described using a separate conceptual diagram, and will not be described here. The created new rule is recorded and held in the same manner as the various rules set by the user described in the second operation description. Regarding this holding operation and the point that the specific recording medium related to it is dedicated to recording a specific continuous program, etc.,
Since the contents of the above-mentioned description of the various rules of the standard setting can be applied as they are, they will not be described in detail here.

Fourth, based on the held association rules, reproduction order rules, and association rules between small blocks,
An operation for reproducing and displaying a program recorded on a recording medium will be described.

For example, when the recording medium 103 is attached to the video / audio data recording / reproducing apparatus, or when the user performs an operation for confirming the recorded contents of the recording medium 103, the recording is performed on the recording medium 103. A list of programs being displayed is displayed on a monitor screen of the display device 109, a small display screen provided on the front panel of the video / audio data recording / reproducing device, or a small display screen provided on a remote controller. After confirming the recorded program by these, the user operates the user operation unit 104 to select a desired program from the recorded programs and perform a reproduction display operation. An operation signal reflecting these operation contents is output to the control unit 101 via the signal line 130.

The control unit 101 reads out a rule for associating with a small block corresponding to the program selected by the user and a reproduction order rule based on an operation signal input via the signal line 130. The association rule and the reproduction order rule are based on the above-described second and third operation descriptions.
3, a recording area other than the above, a semiconductor memory mounted on a disk cartridge, or a recording unit (not shown) provided in the main unit of the video / audio data recording / reproducing apparatus, a storage unit 102 in FIG. Is held by being recorded. When reading out the association rules and reproduction order rules corresponding to the program selected by the user from the semiconductor memory mounted on the recording medium 103 or the disk cartridge, the signal line 127 is stored in the storage unit 102. From the recording unit (not shown) provided on the apparatus, and the control unit 10 via an appropriate signal line.
Read to 1. The control unit 101 generates a control signal for reproduction display based on the read reproduction order rule,
This is output to the decoding unit 107 via the signal line 135.

The control unit 101 reads out the association rules between the small blocks recorded at different dates and times corresponding to the program selected by the user, and performs the reproduction display based on the rules. The rules for associating the small blocks are held by being recorded in the same recording location as the rules for associating with the small blocks and the reproduction order rule according to the second and third description of the operation described above. . However, as described above, the association rules for small blocks, the reproduction order rules, and the association rules between small blocks may all be recorded in the same recording location, or at least one or all May be recorded in different recording locations. The procedure for reading the held association rule is the same as the procedure for reading the association rule for small blocks and the reproduction order rule described above, and thus a description thereof will be omitted. The control unit 101 generates a control signal for reproduction display based on the association rules between the read small blocks, and outputs the control signal to the decoding unit 107 via the signal line 135.

Further, the control unit 101 reads out the compressed and coded stream 128 of the program selected by the user from the recording medium 103 on the basis of the operation signal input from the user operation unit 104 via the signal line 130, and decodes it. 1
07.

The decoding section 107 expands the compressed and coded stream 128 of the program selected by the user, which is read from the recording medium 103. Further, the decoding unit 107 controls the control unit 10 based on the reproduction order rule and the association rule between small blocks read by the control unit 101.
A signal 129 such as an expanded video / audio / sub-picture is output to the display device 109 so as to perform reproduction and display based on the control signal input from 1 through the signal line 135.
Specific examples of the playback display based on the playback order rule include selecting and playing back only the main part or trailer from multiple times of a continuous program recorded at different dates and times, or opening from the time recorded at a certain date and time. And an ending roll, or a trailer or a CM portion is removed and reproduced and displayed.

As a specific example of the reproduction display based on the association rules between the small blocks, for example, the following can be considered. When a plurality of times of a continuous program are recorded on the recording medium 103, it is assumed that the user performs an operation of selecting a favorite time and displaying a digest video. Here, the “next trailer” recorded at a date and time earlier than the time selected by the user (for example, in the same time zone one week before the broadcast date of the main program) is the digest video of the time selected by the user Is called and displayed. If the user is not interested in seeing the displayed digest video and does not want to see the main part of this time, the user does not perform any operation and the main part is not reproduced and displayed. On the other hand, if the user who is interested in watching the digest video wants to see the main part, the user operates the switch provided in the user operation unit 104 to display the digest video. For the “next trailer”, the “main part” of a program recorded at a future date and time (for example, in the same time zone one week after the broadcast date of the trailer) is called up and reproduced.
Such an operation includes a small block corresponding to the main part of the recorded serial program, and a small block corresponding to the next trailer recorded at a date and time in the past (one week before in the example described here) before the main part. This is made possible by setting an association rule between, and recording and holding this association rule.

Further, it is possible to use the association rule between the small blocks and the above-described reproduction order position rule together. For example, a reproduction order rule is created such that only the trailer is extracted from a plurality of times of the continuous program recorded on the recording medium 103 and reproduced and displayed, and the role of the digest video displayed one after another is based on this. When a user who is watching a trailer that is carrying a digest video that is interested in the content is displayed, the user operating unit 10
By operating one of the switches provided in the main program 4, the main video linked from the switch based on the association rule can be reproduced and displayed. Since the reproduction order rules and the association rules between the small blocks are described in detail using a separate conceptual diagram, further detailed description is omitted here.

Finally, fifthly, based on the CM appearance time detected by the CM detecting means, the association rule for the small block previously set and held is modified, and this modified association rule is modified. The following describes the operation in the case where the playback order rule and the association rule between the small blocks, each of which has the small block defined by the above as a constituent element, are applied to the newly recorded next and subsequent times of the continuous program.

In accordance with the above-described third operation description, the program data of the next and subsequent times of the target continuous program input to the video / audio data recording / reproducing apparatus is recorded. that time,
Based on the control signal sent from the control unit 101 via the signal line 136, the CM detection unit 105
, And outputs information 132 such as the appearance time of the CM at the time of the current recording of the target continuous program to the control unit 101 via the signal line 132. Note that the control unit 101 is configured to control the signal line 1
Information necessary for performing control via the CM 32
Obtained from 05.

The control unit 101 controls the video data stored and set in advance based on the number of times a certain continuous program was broadcast in the past based on the procedure described in the third operation description. Are read out, the rules for associating each of the parts with a plurality of small blocks, the rules for reproducing the plurality of small blocks, and the rules for associating the small blocks recorded at different dates and times are read.

Here, the control unit 101 is based on the information 132 such as the appearance time of the CM at the time of the current recording of the target continuous program, which is input from the CM detection unit 105 via the signal line 132. Among the various rules that have been read out, the rules for associating the portions of the video data with a plurality of different small blocks are modified. The corrections made to the association rules are automatically reflected in the reproduction order rules and the association rules between the small blocks, each of which includes the corresponding small block. That is,
This is equivalent to the modification of the reproduction order rule and the association rule. The process of modifying the rules for associating with the small blocks has been described using a separate conceptual diagram, and will not be described here.

The control unit 101 applies various rules modified based on the information from the CM detection unit 105 to newly recorded times of this continuous program, and based on these, small blocks for newly recorded times. Create a rule for associating with, a reproduction order rule, and an association rule between small blocks. At that time, an appropriate program may be read from the storage unit 102 via the signal line 124 as necessary. Specific examples of the creation of these new rules have been described separately using a conceptual diagram, and will not be described here. The created new rule is processed by the same procedure as the standard rules described in the first operation description, similarly to the various rules set by the user described in the second operation description. A management information area on the recording medium 103, other recordable areas, a semiconductor memory mounted on a disk cartridge, or the like, or a recording unit (not shown) provided in the main unit of the video / audio data recording / reproducing apparatus or the storage unit of FIG. It is held by being recorded in 102 or the like. Regarding the holding operation and the point that the specific recording medium related thereto is dedicated to the recording of the specific continuous program, the contents of the description about the various rules of the standard setting described above can be applied as it is.

The operation of the video / audio data recording / reproducing apparatus for realizing the video / audio data recording management method of the present invention has been described with reference to the block diagram. The entire apparatus and the configuration of each processing unit are shown here. It is needless to say that the present invention is not limited to those described above, and can take various forms without departing from the gist of the present invention.

For example, the control unit 101 may be constituted by one LSI, or may be constituted by a plurality of LSIs.
May be a unit composed of In the former case,
For example, a case in which various processes according to the present invention and control of the entire video / audio data recording / reproducing apparatus are intensively processed by one high-performance microcomputer or a high-performance dedicated LSI is exemplified. In the latter case, for example, a case where an LSI for performing various processes according to the present invention is separately provided and placed under the control of an LSI for controlling the entire video / audio data recording / reproducing apparatus is exemplified. In any case, the internal configuration of the control unit 101 can be freely set as long as it is in line with the gist of the present invention.

For example, FIG. 1 shows an example in which the control unit 101 reads out a control program described in the storage unit 102 and performs various processes according to the present invention. However, it is not a unit constituted by one LSI or a plurality of LSIs having such a programmable mechanism, but a non-programmable LSI or LS developed exclusively for performing the processing according to the present invention.
It may be an I unit. In that case, the storage unit 102 for storing the program for performing the processing according to the present invention in FIG. 1 is not required. In any case, the configuration of the control unit 101 is free as long as it conforms to the gist of the present invention.

For example, the storage unit 102 is
It may be in a form built in. Further, in the case of having a function of storing a program for performing processing according to the present invention, a function of rewriting the stored program for a reason such as version upgrade for performance improvement,
It is not necessary to have it, or it may be.
When a program rewriting function is provided, rewriting may be performed via a signal line for program rewriting not shown in FIG. 1 or a route similar to program data may be followed (FIG. 1). The program may be rewritten by writing the downloaded program to the storage unit 102 (by passing a processing unit unrelated to the processing unit 1 by a bypass line not shown). Alternatively, the storage unit 102 may be detached from the video / audio data recording / reproducing device, and a new storage unit 102 in which a new program is written may be attached to the device. In such a case, a part-replaceable image for replacing the LSI on the board or the built-in HDD can be used, or the storage unit 102 is, for example, a semiconductor memory card or a card-type HDD and can be inserted and removed through a dedicated slot A structure for updating the program by taking a simple structure may be adopted. In any case, whether the program stored in the storage unit 102 is rewritable or not,
Regardless of whether the 02 is interchangeable or not, it can take any form as long as it is in accordance with the gist of the present invention.

As described above, a configuration is also conceivable in which the rules for associating the portion of the video data with the small blocks, the reproduction order rules, and the rules for associating the small blocks with each other are not recorded on the recording medium 103. In such a case, these rules may be recorded and held on the video / audio data recording / reproducing apparatus. In this case, the various rules created by the present invention are recorded in a dedicated recording unit (for example, a semiconductor memory or an HDD, not shown in FIG. 1) for the rules provided on the apparatus. Alternatively, the recording unit for the various rules may be shared with a semiconductor memory or HDD which is the storage unit 102 in FIG.
In the latter case, for example, the rule is recorded in the storage unit 102 using the signal line 126 in FIG. In any case, any form can be adopted as long as it is in accordance with the gist of the present invention.

The user operation unit 104 may be, for example, an external editing controller in addition to the above-described remote control and the operation switches on the front panel of the video / audio data recording / reproducing apparatus. A computer may be connected to control the video / audio data recording / reproducing device. In any case, the form of the user operation unit 104 is free as long as it is in accordance with the gist of the present invention.

Further, in the above description, the rules for associating the portions of the video data with the respective small blocks are described. However, this may be literally limited to only the video data, or may be related to the video data. The same processing may be performed on the audio data, the sub-picture data, and the like. Whether to limit to video only or to include audio and sub-pictures is a matter of what kind of variation the application has, so it can take any form as long as it is in line with the gist of the present invention. .

FIGS. 2 to 8 show a process for associating a part of a recorded video with a plurality of different small blocks, and a process for automatically applying the reproduction order rules of those small blocks to the next video of the same continuous program. FIG.

FIG. 2 shows an example of a breakdown of video data of a certain continuous program.

For example, at 19: 0 on February 14, 2000,
It is assumed that the breakdown of the program recorded between 0 and 19:30 has such a configuration when the CM is included in addition to the main part and the trailer.

For this program, as shown in FIG.
Marking is performed at times (A) to (J). The marking may be set manually by a user, for example, or may be automatically applied using any suitable means.

The part of the video data sandwiched between the times of marking is associated with small blocks [B1] to [B9] as shown in FIG.

As shown in FIG. 5, it is assumed that reproduction display of the CM is not performed, and small blocks corresponding to the CM portion are excluded, and [B1], [B2], [B4], [B6],
A playback order rule "Play Rule #m" in which the small blocks of [B7] and [B8] are registered is set. This "Play Rule #
For example, “m” is held in the management information area of the recording medium 103 and is used when reproducing and displaying the video recorded on February 14. In the subsequent recording of this continuous program described below, Set it to be applied automatically.

Now, as shown in FIG.
On February 21, 2000, from 19:00 to 19:30
It is assumed that the next episode of this serial program is broadcasted and recorded.

Here, as shown in FIG.
Reads the "Play Rule #m" that is automatically applied to this series, and reads it on February 21, 2000.
Apply to the next video recorded on the day. As will be described later with reference to FIG. 9, at this time, the control unit 101 reads the “Play R
ule #m "is copied, and a reproduction order rule in which the recording date information of the registered small block is rewritten is created, and is associated with the next edition of the newly recorded serial program.

As a result, as shown in FIG. 8, the part of the next compilation video of the continuous program newly recorded on February 21 could be associated with the small block. This "Play
The new reproduction order rule obtained by copying the rule #m "and rewriting the information on the recording date of the small block is held by the control unit 101, for example, in the management information area of the recording medium 103, and newly recorded on February 21. It is used when reproducing and displaying the next edited video of the continuous program.

FIG. 9 is an example of a table describing the reproduction order rules of the small blocks used in the description with reference to FIGS.

In the “Play Rule #m”, as described in the table of FIG. 9B, at least for each registered small block, at least the recording date and the start / end time of the small block are described. Have been.

Here, when this "Play Rule #m" is automatically applied to newly recorded video data at a later date (for example, February 21, 2000 in the example described with reference to FIGS. 6 to 8), Is "Play Rule #m" as shown in FIG.
"Play Rule #" in which the recording date is rewritten to a new date (February 21, 2000 in FIGS. 6 to 8).
Create and hold m '".

FIG. 10 is a flowchart showing a process for setting a reproduction order rule of a small block associated with a part of video data for a recorded continuous program.

The user uses the user operation unit 104, for example, a remote controller, to instruct recording of a certain time of a continuous program, and based on this instruction, the control unit 101 controls the recording medium 103.
(Step S301). The control unit 101 determines that the playback order rule applied to the recorded
3 is checked (step S302). Note that the above-mentioned reproduction order rule is determined by the recording medium 10 as described above.
3 is stored in a management information area, other recordable areas, a semiconductor memory mounted on a disk cartridge, or the like.

If there is no reproduction order rule to be applied as in the case of recording the first time of a continuous program (N in step S302), the user operates the user operation unit 1
From 04, a process of associating the recorded video portions with the small blocks is performed (step S303). This corresponds to FIGS. 3 and 4 described above. At this time, for each small block, the recording date of the video data associated with the small block and the recording time of the video data portion serving as the start point / end point of the small block are set. The setting need not be performed manually by the user. Control unit 101
Sets a reproduction order rule for the small block associated with the user (step S304). This constitutes the one shown in FIG. And the control unit 1
No. 01 stores in the recording medium 103 the rules for associating the recorded video portion with the small blocks and the rules for reproducing the small blocks (step S305). These may be held independently as described above, but here it is assumed that they are integrally held as shown in FIG.

In step S302, for example, when the next or subsequent time of the continuous program in which the reproduction order rule is held is recorded, that is, when there is a reproduction order rule to be applied (Y in step S302), the control unit 101 Then, the reproduction order rule and the rule for associating with the small block held for the continuous program are read from the recording medium 103 (step S306). In this embodiment, since the reproduction order rule and the association rule for the small block are held integrally, they are read out together. The read reproduction order rule is made to correspond to the next and subsequent times of the newly recorded continuous program (step S307). Specifically, the following are mentioned. For example, as described with reference to FIGS. 2 to 8, after reading the reproduction order rule, this is copied, the recording date is rewritten, and the newly recorded serial program is used for the next and subsequent times. . In addition, for example, a process of additionally registering a description of the next and subsequent times of a newly recorded continuous program in one playback order rule. An example of the latter process will be described later. In this way, the control unit 101 holds the reproduction order rule corresponding to the newly recorded continuous program in the next and subsequent times on the recording medium 103 (step S30).
8).

The above-described steps S302 to S305
Or the processing from steps S306 to S308, the reproduction order rule for the recorded continuous program is set and held.

Thereafter, the user determines whether or not to continue recording the continuous program. If the recording is to be continued (Y in step S309), the processing from step S301 is applied to another date and time. If the recording of the continuous program is not to be continued any more (N in step S309), for example, when the recording of the continuous program is interrupted or when the last recording is completed, the processing is terminated.

FIG. 11 is a flow chart showing an example of a case where the recorded video data is reproduced and displayed based on the reproduction order rule set in the procedure described above with reference to FIG.

First, the user checks the recorded program on the monitor screen of the display device or the like, and then checks the user operation unit 10
4 is operated to select a desired program from the recorded programs and perform a reproduction display operation. Based on the operation signal, the control unit 101 selects a small block playback order rule #m to be used for playback and display of the continuous program selected by the user, and starts playback and display (steps S401 and S40).
2). Further, the control unit 101 reads the recording date and the times of the start point and the end point of the small block #n registered in the reproduction order rule #m from the recording medium 103 (step S40).
3). The video data specified by the read recording date is specified as the video to be played back and displayed (step S40).
4). For example, when only the main part of a drama is extracted and reproduced and displayed, a plurality of video data having different recording dates may be reproduced and displayed. The video data of the portion between the start point and end point times read out in step S403 earlier in the designated reproduction display target video is reproduced and displayed (step S40).
5). Subsequently, the control unit 101 checks whether or not the reproduction and display of the video corresponding to all the small blocks registered in the reproduction order rule #m have been completed, and if not completed (N in step S406), the next After switching to the small block of
The video data corresponding to the small block is reproduced and displayed according to the processing from steps S403 to S405 (step S407). When completed (Y in step S406), the reproduction and display of the video data based on the reproduction order rule #m is ended.

FIGS. 12 to 15 show examples of the reproduction order rules used to extract and reproduce and display only the main video.

In this example, the first recording is performed on January 31, 2000, the next and subsequent programs broadcast every week at the same time are recorded, and only the main video is extracted from the recorded programs. And play back and display. In this case, each time a new video is recorded, a small block of the main part in the video is additionally registered in one playback order rule “Play Rule #mm”.

Further, only the small block [B2] of the opening only for the first broadcast is reproduced and displayed. Further, only the newest video currently recorded is reproduced and displayed in the small block [B7] of the ending roll. In this case, when registering the small block associated with the new video, the small block of the ending roll corresponding to the video that is one time older than the latest video is registered in the playback order rule “Play Rule #m
m ”.

FIG. 16 is an example of a table describing the reproduction order rules of the small blocks used in the description with reference to FIGS.

As described above, small blocks corresponding to the main part of the newly recorded video are additionally registered in “Play Rule #mm”. In the table of FIG. 16, a shaded portion is a newly additionally registered portion.

FIGS. 17 to 20 show examples of the reproduction order rules used to extract and reproduce and display only the next trailer video.

As described above with reference to FIGS. 12 to 15, one playback order rule “Play Rule #mmm”
Each time a new video is recorded, a small block of the next trailer in the video is additionally registered. By using such a reproduction order rule, it can be used as a digest video for grasping an outline of a plurality of videos recorded on a recording medium such as a DVD-RAM.

FIG. 21 is an example of a table describing the reproduction order rules of the small blocks used in the description with reference to FIGS.

As described above, small blocks corresponding to the next trailer of newly recorded video are additionally registered in “Play Rule #mmm”. In the figure, the shaded portion is a newly additionally registered portion.

FIGS. 22 to 25 show examples of a reproduction order rule used for removing and displaying a CM portion from a recorded video image for reproduction and display. This is different from the reproduction order rules of FIGS. 12 to 15 and FIGS. 17 to 20 which are used earlier, and no additional registration of small blocks is performed.

In the example of FIGS. 22 to 25, January 3, 2000
After holding the playback order rule “Play Rule #n” set based on the video recorded on one day, when recording the video of the same continuous program that is broadcast every other week, "Play Rule #n '", "Play Rule"
The process of automatically applying e # n "" and "Play Rule #n"'"to the video recorded respectively on February 7, 14, and 21 in the example of FIGS. Is going.

FIG. 26 is an example of a table describing the reproduction order rules of the small blocks used in the description with reference to FIGS.

As shown in this table, “Play Rule #
n '”,“ Play Rule #n''”and“ PlayRule #n''' ”are“ Pl
It is based on a copy of ay Rule #n ”. The configuration of registered small blocks and the start and end times of each small block are the same, but the recording date of the small block in the shaded portion is rewritten. Have been.

Up to this point, the reproduction order rules of a plurality of small blocks corresponding to the partial portions of the recorded video data have been described. Now, the association between the small blocks recorded at different dates and times will be described.

It is convenient for the user to have a digest video that can give an overview of the content of the video recorded on a recording medium such as a DVD-RAM in a short time. However, a screen that is mechanically extracted from a recorded program at regular time intervals or a screen that extracts only scene changes is a digest of a recorded program as a simple screen. Is weak as a meaningful image expressed in
It is hard to say that it is appropriate as a digest of a recorded program.

By the way, the next trailer is almost always attached at the end of the serial program. This trailer is created by the program creator in a deliberate manner so as to appropriately show the contents of the next program within a limited short time. Therefore, when recording a continuous program, it is very useful to use the next trailer as a digest video.

First, by forming a reproduction order rule in which only the small blocks corresponding to the next trailer portion are registered, it is possible to grasp the outline of the video recorded on the recording medium such as the DVD-RAM in a short time. It was explained that it can be used as a digest video that can be used.

The small block playback order rule described above describes the procedure of playback and display by dividing recorded video data into partial parts. Are all reproduced and displayed in the registered order. Therefore, a mechanism for reproducing and displaying only the main part or only the trailer, or for reproducing and displaying the trailer and the main part continuously can be easily configured. However, as a result of grasping the outline in the trailer, whether or not the main part video is reproduced and displayed depending on whether or not the interest is raised cannot be constituted by the reproduction order rule of the small blocks described above. If the trailer and the main part are registered in the same reproduction order rule, both parts are always reproduced and displayed. Also, if you registered each with a separate play order rule,
After watching the trailer, it is necessary to search for the reproduction order rule in which the main part is registered, which is complicated.

In order to realize such a function, the association between the small blocks recorded at different dates and times, which is defined separately from the reproduction order rule of the small blocks, becomes effective. Basically, only one of the small blocks to which this association has been made is reproduced and displayed. However, for example, when the user performs an operation such as pressing one switch of the remote control,
It is possible to reproduce and display the other small block with which the association has been made. The video corresponding to the small block to which the association is made may be reproduced and displayed after the reproduction of the video corresponding to the small block that is first reproduced and displayed, or may correspond to the first small block. The reproduction of the video may be interrupted and the reproduction of the video corresponding to the other small block may be performed.

FIG. 27 is a flowchart of a process for setting an association between small blocks recorded at different dates and times. In this flowchart, the association between the small blocks is referred to as a link.

First, the user instructs, via the user operation unit 104, to read a list of small blocks that can be registered in a link. Display. Users can refer to this displayed list,
Set association between small blocks (step S60)
1). Then, the link # 1 is set (step S602). Further, the user selects a small block #y to be associated, that is, to be linked (step S603). Also, the selected small block #
The recording date of y is selected (step S604).

The control unit 101 registers the small block #y to the link #l by the selection operation of the small block #y and the recording date of the small block #y, and the recording medium 10
No. 3 (step S605). Subsequently, the user determines whether or not to end the selection of the small block to be registered in the link # 1, and if the user continues to select the small block to be registered (N in step S606), the previous step S60.
The processes from 3 to S605 are repeated. When ending the selection of the small block to be registered (Y in step S606),
The link #l for which the registration of the small block has been completed is recorded.

Next, the user determines whether or not to set the link # l + 1, which is a new association, and if the setting is to be made (Y in step S608), step S6 described above is performed.
02 to S607). When the setting is not performed (N in step S608), the setting of the association between the small blocks recorded at the different date and time is ended.

FIG. 28 is a conceptual diagram of a process of setting an association between small blocks recorded at different dates and times.

In the example of FIG. 28, January 31, 2000
The small block [B8] corresponding to the trailer in the video recorded on the day and the small block [B] corresponding to the main video in the next video recorded on February 7, 2000 one week later
1], [B2], [B4], [B6], and [B7]. Thus, a user interested in watching the trailer recorded on January 31 can be operated by a simple operation such as pressing a switch on a remote controller, for example.
The associated main video recorded on February 7 can be reproduced and displayed.

As will be described later with reference to FIG. 29, it is needless to say that the association is made between each small block and that the small block [B
A plurality of small groups, such as [1], [B2], [B4], [B6], [B7], which can be treated as a group for continuous playback and display of the main video, are summarized. It is possible to associate a group as a pseudo small block.

The association between the small blocks and the above-described small block reproduction order rule have different definitions, and therefore can be used together. For example, by registering a plurality of small blocks of the trailer video associated with the small blocks corresponding to the main video in the playback order rule, for example, while the trailer video is continuously reproduced and displayed, It is also possible to reproduce and display the main video with a single switch operation from the reproduction and display of the trailer video of the content.

FIG. 29 is an example of a table describing rules for associating small blocks recorded at different dates and times. For simplicity, this table describes the association between two small blocks, but it is also possible to describe the association between three or more small blocks depending on the application.

The association rule “Link # 1” described in the table of FIG. 29 corresponds to the example described above with reference to FIG. 28, and includes the trailer recorded on January 31 and The content is associated with the main part recorded on February 7. As mentioned earlier, February 7
The small blocks [B1], [B2],
[B4], [B6], and [B7] are a group of groups for reproducing and displaying the main video. Therefore, in the main table (A) describing the association, the small block [B
8] is the content associated with “Group 1”. For “Group 1”, “Gro” is used to indicate that a plurality of small blocks are grouped.
"YES" appears in the "uped?" section. Subtable (B)
In addition, "Group 1" is a small block [B
1], [B2], [B4], [B6], and [B7] are described as a lump.

Since the contents of the table shown in FIG. 29 are held on the recording medium 103, for example, the table contents are stored in the newly recorded video data in the same manner as the reproduction order rule of the small group. It is needless to say that the association between the small blocks described in (1) can be automatically applied.

FIGS. 30 to 37 show the case where the stored reproduction order rule between small blocks is not directly applied to newly recorded video data, but the starting point / small point of the small block registered in the reproduction order rule. FIG. 14 is a conceptual diagram of an example in which an end point time is corrected and applied.

The start and end times of the part of the continuous program are as follows:
It may change slightly each time due to the circumstances of the program producer. In a method according to the present invention in which a part of video data is made to correspond to a small block having pointer information, the recorded video data remains as it is unless the data is intentionally erased. ing. Therefore, even if the start and end times of the main part deviate from the description of the stored small block, rewriting the start and end times of each of the small blocks corresponding to the newly recorded video data will cause a problem. Does not occur. This may be manually rewritten by the user later, but can be automatically rewritten to some extent.

For example, even if the broadcast time of the CM is shifted, the length of the CM frame itself hardly changes due to the sponsor contract of the program. FIGS. 30 to 37 show an example of rewriting the start and end times of the small block based on the appearance times of the CM portion where the broadcast time length does not change. In this example, for simplicity of explanation, the opening time, the ending roll, and the broadcast time length of the next trailer are not changed.

FIGS. 30 to 33 correspond to FIGS.
8 shows a process according to FIG. In FIG. 34, the start and end times of the CM portion are checked by using the existing CM detection means such as detecting the switching portion of stereo / monaural sound while recording the newly broadcasted next video. I have. As a result, it can be seen that such a time lag has occurred in comparison with the start and end times of the individual small blocks already held.

In FIG. 35, based on the result of FIG. 34,
Playback rule for small blocks already held "Play Rule #
m ". The start and end times of the small blocks registered in" m "are corrected.
ule #m (modified) ”.

In FIG. 36, the reproduction order rule “Play Rule #m” with this correction applied to newly recorded video data
(modified) ”is applied.

As a result, in FIG. 37, correspondence with the corrected small block is made.

Since it is not clear when and how long the broadcast time shift of such a portion occurs as a time shift, the original “Play Rule #m” is maintained and corrected every time. It is considered that the technique is fundamental. However, all modified “Play Rule #m (modified)” will be retained and the appropriate “Play Rule #m (modi
fied) ”.

The embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to the embodiment, and the gist of the present invention is not limited to that shown here. It goes without saying that various forms can be taken without departing from the scope.

Further, the following can also be realized in connection with the embodiment of the present invention.

For example, when the time frame is enlarged and broadcast at the first time or the last time, a warning is displayed so that exception processing is performed. For the first broadcast, a digest video created by another suitable means is used as a substitute for the trailer. In addition, if the trailer and the main part to be associated become separate disks because the disk is full, a warning is displayed to the user, and the same as the next main part using the HDD or large-capacity memory built into the device. The device may be provided with a mechanism for performing operations such as copying a trailer video onto a disc.

[0139]

As described above, according to the present invention, by utilizing the regularity of a recorded continuous program,
Rules such as the playback display of only the main part or the trailer, or the playback display with the CM removed are automatically applied to the sequel of the newly recorded continuous program, thereby improving the user's convenience. .
