2. Description of the Related Art Regarding next-generation digital broadcasting, 20
BS digital broadcasting will be started from 2000, and terrestrial digital broadcasting will be started from around 2003. When the current analog broadcasting becomes the next-generation digital broadcasting, the current HDTV
(High Definition TeleVision) 2 channels of HDTV can be transmitted using the radio waves of 1 channel.
In addition, using the radio wave that transmits HDTV 1 channel
SDTV (Standard Definition TeleVision) 3 channels can also be transmitted. It is possible for the broadcasting station to select which of HDTV / SDTV is to be broadcasted, and it becomes possible to provide programs with a greater degree of freedom.

Also, an electronic program guide or the like is transmitted as additional information. The electronic program guide transmits the TV guide information by radio waves at what time and what program is to be broadcast, and recording reservations can be made on the electronic program guide. Also, some recording devices have the advantage that the reserved recording start time can also be automatically postponed, such as when the baseball broadcast is extended and the start time of the program reserved for recording after that is extended. In addition to the above functions, digital broadcasting-related equipment is highly expected in the future.

[0004]

However, in the prior art, when broadcast data in which a plurality of channels are multiplexed is recorded in an optical disk device or a hard disk device,
Data of a plurality of channels will be continuously recorded, that is, as shown in FIG. 10, (1 channel data (101) → 2 channel data (102) → 3 channel data (103) → ... 1 channel Data (1
01) → 2 channel data (102) → 3 channel data (103) → ... 1 channel data (10
It is recorded in the form of 1) → 2 channel data (102) → 3 channel data (103) → ... Therefore, as shown by the recording area 104 in FIG. 10, different channel data are continuous on the disc, and even if one channel of the channel data is reproduced and viewed, it is necessary to frequently jump at the time of reproduction, which is stable. There is a problem that it is difficult to realize the normal playback and advanced trick playback functions.

On the other hand, as the number of channels that can be broadcast increases, it is expected that the contents of programs to be broadcast will also diversify,
There is a demand for a recording / reproducing system capable of flexibly coping with such highly flexible broadcasting. Specifically, for example, in a quiz program, a quiz and hints of several stages are transmitted, and the receiving side does not want to see the hints / see the low level hints / see the intermediate level hints depending on the viewer's preference. Even if one wants to select / see a high-level hint, etc., the conventional technology cannot handle it.

Also, in a foreign language conversation program, etc., you want to change the speed at which the other person speaks according to your conversation level, want to talk between phrases with yourself in between, and set the open time yourself. Even if the user wants to do so, the conventional technology cannot handle it.

[0007] Further, a viewer who has not paid the viewing fee or has paid a low amount of the viewing fee is asked to watch the CM, and is paying the viewing fee or a viewer who has paid the high amount of the viewing fee. Even if you think that you want to cut and watch commercials that are sandwiched between contents, it is not possible with conventional technology.

The present invention has been made in view of such problems, and an object of the present invention is to enable stable normal reproduction, advanced trick reproduction, and the like, and yet to have various degrees of freedom. Another object is to provide a broadcast recording method, a broadcast reproducing method, a broadcast recording device, a broadcast recording / reproducing device, and a recording medium thereof that can flexibly cope with high broadcasting.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a digital broadcasting system will be briefly described before describing a recording method and a reproducing method relating to a broadcast recording / reproducing apparatus according to the present invention. For example, in the case of BS digital broadcasting, one broadcasting station can simultaneously broadcast HDTV 1 channel to SDTV 3 channel. Video / audio signals are MPEG-2
(MovingPicture E Digital broadcast recording / playback pert Grou
It is compressed by p) and is transmitted by TS (Transport Stream). In the case of SDTV 3 channel simultaneous broadcasting, the data of each channel is placed in different TS,
Which channel contains data in each TS is identified by data called PID (Program ID) in the TS header. For example, if the PID is 1001H (H: hexadecimal display), the channel 1 data, if 1002H, the channel 2 data, 1
By predetermining the PID and the channel number, such as the data of channel 3 when 003H, it is possible to determine how many channels of data are being received by the PID.

A recording method and a reproducing method relating to the broadcast recording / reproducing apparatus according to the present invention will be described in detail below with reference to FIGS. As the recording medium, for example,
A disc-shaped recording medium such as an optical disc or a magnetic disc (hereinafter, simply referred to as a disc) is used. In the following description, the case where the present invention is applied to BS digital broadcasting in which one HDTV channel to three SDTV channels are simultaneously broadcast per broadcasting station will be described. Also,
The additional information in the following description includes the PID and indicates all information related to the decoding / reproducing process other than the contents of the broadcast.

FIG. 1 is a conceptual diagram showing a first recording method and reproducing method relating to a broadcast recording / reproducing apparatus according to the present invention. The first recording method shown in FIG. 1 records a predetermined one of the contents of three channels broadcast in time division. Specifically, when recording a broadcast stream in which channel 1 (11), channel 2 (12), and channel 3 (13) are continuously transmitted for each TS on a disc, recording is performed while detecting the PID. For example, PID = 1001
Only H, that is, the data of channel 1 is recorded in 14.
In addition, on the disc recorded in this way, the normal continuous reproduction is performed on the data 14 of the channel 1 when reproducing. That is, PID = 1001H, 1002H, 1003H is sent in broadcasting, but only 1001H data is recorded when recording.

Regarding the above-mentioned first recording method,
You may record only the data of PID = 1002H.
Only the data of 1003H may be recorded. Select and record one program selected by the user. The user may also select a genre. For example, if you select "News", the time when the news is automatically broadcast is set even when the news is performed on channel 1 from 7:00 to 7:30 and on channel 3 from 9:00 to 9:15. Select a channel and only that program will be recorded. In that case, the selection is made by the electronic program guide.

FIG. 2 is a conceptual diagram showing a second recording method and reproducing method relating to the broadcast recording / reproducing apparatus according to the present invention. In the second recording method shown in FIG. 2, while detecting the PID, the data (21) with PID = 1001H is recorded in the area 1 (24) in the disc, and the data (22) with PID = 1002H is recorded in the optical disc. Area 2 (25), and the data (23) with PID = 1003H is recorded in area 3 (26) in the disc. That is, when recording, for example, for each TS (area 1 (2
4) → area 2 (25) → area 3 (26) → area 1 (2
4) → area 2 (25) → area 3 (26) → ...) while jumping and recording.

When reproducing channel 1 data (21) on a disc recorded in this way, only area 1 (24) and channel 2 data (2) are reproduced.
When reproducing 2), only area 2 (25) is reproduced, and when reproducing channel 3 data (23), only area 3 (26) is reproduced. For this reason, the number of jumps during reproduction is reduced, and stable normal reproduction and retry can be performed depending on the conditions. In addition, special playback such as fast-forward, which is a function peculiar to playback, and non-linear playback in which streams at distant positions on the disc are connected without interruption can be easily performed.

Although not shown in the drawing, a part of a plurality of programs, for example, data having a PID of 1001H is recorded in the area 1 of the disc, and data of 1003H is recorded in the area 2 of the optical disc. May be. In this case, at the time of recording, for example, for each TS (area 1 → area 2 → area 1 → area 2
Although it is necessary to jump to and record the data, only the area 1 should be reproduced when reproducing the channel 1 data, and only the area 2 should be reproduced when reproducing the channel 3 data. . This is because the number of jumps during playback is reduced, as in the case described above.
Stable normal playback and retries are possible depending on the conditions, and special playback such as fast-forward, which is a unique function during playback, and non-linear playback that connects streams at distant positions on the disk without interruption, are easily possible. Become.

FIG. 3 is a conceptual diagram showing a third recording method and reproducing method relating to the broadcast recording / reproducing apparatus according to the present invention. In the digital broadcasting in this case, a quiz program (31) is transmitted as the main content, a low-level or insignificant hint (32) for the quiz is transmitted as the additional content 1, and an additional content 2 is transmitted for the quiz. It is assumed that a medium level hint (33) is sent and a high level or very important hint (34) for the quiz is sent as additional content 3.

As a transmission method, it is not necessary to transmit the main content as the program 1, the additional content 1 as the program 2, the additional content 2 as the program 3, and the additional content 3 as the main content as the program 3 and the additional content 1. The program 1 and the additional content 2 may be the private data in the program 2, and the additional content 3 may be the program 2. There are various other combinations, and any of them may be adopted.

In the following, the main content quiz program is program 1, the low level hint of additional content 1 is program 2, the middle level hint of additional content 2 is program 3, and the high level hint of additional content 3 is program 3
The private data inside.

When the broadcast is received, the third recording method also records in the same manner as the second recording method described above. That is, the quiz program is recorded as the program 1 in the area 1 (35) in the disc, the low level hint is recorded as the program 2 in the area 2 (36), and the medium level hint is recorded as the program 3 in the area 3 (37). At the same time, the high level hint is recorded in the area 3 (37) as private data. At the time of reproduction, it is recognized that the quiz program is recorded as program 1, the low level hint is program 2, the middle level hint is program 3, and the high level hint is recorded as private data based on the control data separated from the broadcast. Next, the program 1 is reproduced and the quiz program is displayed on the upper half of the television screen, for example.

When a "hint" or "1" is input from an external control unit (hereinafter, simply referred to as a remote controller) as an input means of the broadcast recording / reproducing apparatus, the program 2 is reproduced and a low level hint is given. It is displayed in the left third of the lower half of the TV screen. From the remote
When hints "2" are input, program 3 is played and the middle level hint is displayed at the center 1 of the lower half of the TV screen.
/ 3 is displayed. When "Hint" or "3" is input from the remote controller, the private data is reproduced and the high level hint is displayed in the right third of the lower half of the TV screen. As described above, the viewer can enjoy the quiz program according to the knowledge level by selecting and displaying the favorite hint.

In the third recording method and reproducing method described above, it is not always necessary to record all quiz programs, low level hints, middle level hints, and high level hints.

Although not shown, for example, a case where the quiz program of the main content is the program 1 and the low-level hint of the additional content 1 is the program 2 will be described below. When the broadcast is received, the quiz program is recorded as program 1 and the low level hint is recorded as program 2. Then, at the time of reproduction, the system first recognizes from the control data that the quiz program is recorded as program 1 and the low level hint is recorded as program 2. Next, program 1
Is played and the quiz show is displayed in the upper half of the TV screen. And when "1" is input from the remote controller,
Program 2 is played and low level hints are displayed, for example, in the lower half of the television screen. Thus, the viewer can enjoy the quiz program according to the knowledge level by selecting and displaying the hint.

Now, the control data for recognizing the contents of the broadcast and for defining the recording / reproducing procedure as described above will be described. Figure 8 shows TS (Transport Packet)
It is a conceptual diagram which shows the structure of. As shown in FIG. 8, TS (Tran
sport Packet) consists of header and payload.
The payload is a PSI consisting of PES packet in which video / audio data is placed and other data.
Consists of one of the sections. PSI section
Data called PAT, CAT, PMT, etc., or Private s
Composed of ection. In the Private Section, you can send freely usable data.

In the above-mentioned third recording method and reproducing method, various kinds of information are arranged in advance for the private section thus configured. Specifically, Privat
Information indicating the program display mode is arranged in the upper 2 bits of the e section data, and (00: program display 01: program /
CM display). When the program is displayed (00), information indicating the genre of the broadcast is arranged in the next 4 bits, which is (0000: Quiz program 0001: Foreign language conversation ...). Further, in the case of a quiz program, information indicating the contents of contents in the main streams of channels 1, 2, and 3 is arranged in the next 2 bits × 3, and (00: quiz program 01: low level hint 1
0: Medium level hint 11: High level hint). In addition, for the next 2 bits × 3, channel 1,
Information indicating the content of the contents in a few private streams is shown, and (00: Quiz program 01: Low level hint 10: Medium level hint 11: High level hint. The correspondence relationship of this information is as follows: The content is not limited to the above-mentioned specific example, and other content may be used as long as the content of the channel is known.

FIG. 4 is a conceptual diagram showing a fourth recording method and reproducing method relating to the broadcast recording / reproducing apparatus according to the present invention. In this case, in a foreign language conversation program or the like, the speed at which the other party speaks can be changed according to his or her conversation ability level. In digital broadcasting, for example, an English conversation program of the main content is transmitted as program 1 (41), and a level 1 speed multiplication factor of speaking a little slowly is given as program 2 (42).
In the program 3 (4
It shall be transmitted as additional information in 3).

Specifically, in the program 2 (42),
In Program 1 (42), the speed multiplier, for example, a value of 0.9 is transmitted only while the English teacher is speaking. It should be noted that a value of 10 is transmitted by the program 2 (42) because it is not slowed down in commentary in Japanese other than English, commercials, and the like. Further, in the program 3 (43), the speed multiplier, for example, a value of 0.7 is transmitted only while the English teacher is speaking. Values such as 10 are not used for explanations in Japanese other than English, commercials, etc.
It is transmitted in 3).

When the broadcast is received, recording is performed in the fourth recording method as in the second and third recording methods described above. That is, the English conversation program is recorded as the program 1 in the area 1 (44) of the disc, the level 1 speed multiplication factor is recorded as the program 2 in the area 2 (45), and the level 2 speed multiplication factor is recorded as the program 3 in the area 3 ( 46).

At the time of reproduction, the broadcast recording / reproducing apparatus first recognizes from the control data that the English conversation program is recorded as program 1, the level 1 speed multiplication factor is program 2, and the level 2 speed multiplication factor is program 3. To do. Next, the program 1 is reproduced and the English conversation program is displayed on the television screen. Normally, when nothing is input with the remote controller, the recorded English conversation program is played back at normal speed.

Then, from the remote control, "speed", "
When "1" is input, the program 2 is played and the speed magnification of the English conversation program is analyzed. If the magnification is 0.9, the playback speed is reduced to 0.9 times, and if the magnification is 10, that portion The playback speed is returned to 10. Also, when "speed" or "2" is input from the remote control, program 3 is played back and the speed magnification of the English conversation program is analyzed. If the speed drops to 0.7 times and the magnification is 10, the speed of that part will return to 10 times.

As described above, the viewer can freely learn the language by simply selecting the conversation speed according to the English ability by operating the remote controller. There is also a method of inputting the speed multiplication information itself from the remote controller with a ten-key pad. In that case, a numerical value other than 10 out of the recorded speed multiplication is temporarily replaced with the input numerical value and executed. Since the speed multiplication information has a very small amount of information, it is generally transmitted not as a program but as private data in the gap in the program 1. In such a case, it is possible to broadcast English conversation and speed magnification information in program 1, German conversation and speed magnification information in program 2, and French conversation and speed magnification information in program 3. Furthermore, the level of the speed multiplying factor is not limited to the two types of 1 and 2 as described above, and may be more than one.

Here, the control data for recognizing the contents of the broadcast and for defining the recording / reproducing procedure will be described. In the above-described fourth recording method and reproducing method, various kinds of information are arranged in advance in the Private section. Specifically, the top two Private Section data
Information indicating the program display mode is arranged in the bit, and (0
0: Program display 01: Program / CM display). Further, when the program is displayed (00), information indicating the genre of the broadcast is arranged in the next 4 bits (0000: quiz program 0001: foreign language conversation 0002: ...)
It is said that. In the case of a foreign language program, the next 4 bits carry information indicating what language it is (0000: English
0001: German 0002: French ・ ・ ・ ・
・ ・)

As described above, in the next 2 bits in which the predetermined information is arranged, information indicating the contents of the subsequent 8 bits for channel 1 is arranged, and (00: foreign language program 0
1: Speed multiplication factor 10: Interval time ...
...). Then, for the next 8 bits, for channel 1, when the previous 2 bits are 00, 00
When H, 01 to 10, information indicating the speed multiplying factor or the interval time is arranged.

Further, as described above, in the next 2 bits in which the predetermined information is arranged, information indicating the contents of the subsequent 8 bits for the channel 2 is arranged, and (00: foreign language program 01: speed multiplication factor) 10: Interval time
...). And for the next 8 bits, for channel 2, when the previous 2 bits are 00,
When 00H and 01 to 10, information indicating a speed multiplication factor or an interval time is arranged.

Further, as described above, in the next 2 bits in which the predetermined information is arranged, information indicating the contents of the subsequent 8 bits for the channel 3 is arranged, and (00: foreign language program 01: speed multiplication factor) 10: Interval time
.........). And for the next 8 bits, for channel 3, when the previous 2 bits are 00,
When 00H and 01 to 10, information indicating a speed multiplication factor or an interval time is arranged. Note that the correspondence relationship of this information is not limited to the above-described specific example, and may be another one as long as the content content in the channel, the speed magnification, the interval time, and the like are known.

FIG. 5 is a conceptual diagram showing a fifth recording method and reproducing method relating to the broadcast recording / reproducing apparatus according to the present invention. In this case, in a foreign language conversation program or the like, it is possible to speak after the other party speaks and change the interval length according to the conversation level of the person. In digital broadcasting, for example, an English conversation program of the main content is transmitted as a program 1 (51), and an interval of a normal length is taken as a level 1 level.
The interval time of 2 is transmitted as additional information in the program 2 (52), and the interval time of level 2 in which a longer interval is taken is the program 3 (5).
It is assumed that it is transmitted as additional information in 3).

Specifically, in the program 2, when the English teacher finishes speaking, an interval time of a normal length, for example, a value of 3 indicating 3 seconds is transmitted.
Nothing is transmitted in other parts. Further, in the program 3, when the English teacher finishes speaking, a longer interval time, for example, a value of 6 indicating 6 seconds is transmitted. Nothing is transmitted in other parts.

When the broadcast is received, the recording is performed in the fifth recording method as in the second to fourth recording methods described above. That is, the English conversation program is recorded as the program 1 in the area 1 (54) of the disc, the level 1 interval time is recorded as the program 2 in the area 2 (55), and the level 2 interval time is recorded as the program 3 in the area 3 ( 56).

At the time of reproduction, first, the broadcast recording / reproducing apparatus uses program 1 for the English conversation program, program 2 for the interval time of level 1, and level 2 from the control data.
It is recognized that the interval time of is recorded as the program 3. Next, program 1 is played,
The English conversation program is displayed on the TV screen. Note that normally, when nothing is input, the recorded English conversation program is reproduced at normal speed. Here, there is no interval time after the teacher talks, and the teacher's talk continues.

When "interval time" and "1" are input from the remote controller, the program 2 is reproduced and the interval time of the English conversation program is analyzed. If the interval time is 3, the part is reproduced for 3 seconds. Shutdown will be implemented. Also, when "Interval time" and "2" are input from the remote control, the program 3
Is reproduced and the interval time of the English conversation program is analyzed. If the interval time is 6, the reproduction is stopped for 6 seconds at that part.
