2. Description of the Related Art For next-generation digital broadcasting, 20
BS digital broadcasting is scheduled to start in 2000, and terrestrial digital broadcasting will start in around 2003. When current analog broadcasting becomes next-generation digital broadcasting, HDTV
(High Definition TeleVision) Two channels of HDTV can be transmitted using radio waves transmitted by one channel.
In addition, using the radio wave transmitted one HDTV channel
It can also transmit SDTV (Standard Definition TeleVision) three channels. The broadcasting station can select which of the HDTV and the SDTV to broadcast, and a program with a greater degree of freedom can be provided.

Further, an electronic program guide or the like is transmitted as additional information. The electronic program guide transmits what kind of program is to be broadcasted at which time, and transmits TV guide information by radio waves in the gap between the video / audio information. Recording can be reserved on the electronic program guide. In addition, some recording devices have advantages such as the ability to automatically postpone the scheduled recording start time, such as when the baseball broadcast is extended and the start time of the program reserved for recording is extended. Digital broadcasting-related devices are expected to be very popular in the future, together with the functions described above.

[0004]

However, in the prior art, when broadcast data in which a plurality of channels are multiplexed is recorded on an optical disk device or a hard disk device,
That is, data of a plurality of channels is 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
1) → 2 channel data (102) → 3 channel data (103) →...). For this reason, 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 data is to be reproduced and viewed, it is necessary to make frequent jumps at the time of reproduction. There is a problem that it is difficult to realize the normal playback function and the advanced trick playback function.

On the other hand, if the number of channels that can be broadcasted increases, it is expected that the content of the broadcasted program will also be diversified.
There is a demand for a recording / reproducing system that can flexibly cope with such a high degree of freedom in broadcasting. Specifically, for example, in a quiz program or the like, a quiz and several steps of hints are transmitted, and the viewer does not want to see hints / view low-level hints / view medium-level hints depending on the viewer's preference. Even if one wants to select / view high-level hints, it is not possible with conventional techniques.

In a foreign language conversation program or the like, the user wants to change the speed at which the other party speaks according to his or her conversation level, wants to speak between himself and another between phrases, and sets his own time to open. Even if one wishes to do so, it cannot be handled by the conventional technology.

[0007] Further, viewers who have not paid the viewing fee or who have paid a low viewing fee have the CM viewed, and those who have paid the viewing fee or paid the high viewing fee. However, conventional technology is not able to respond to the problem of cutting commercials that are sandwiched between contents for viewing.

The present invention has been made in view of such a problem, and an object of the present invention is to enable stable normal reproduction, advanced trick reproduction, and the like. It is an object of the present invention to provide a broadcast recording method and a broadcast reproducing method, a broadcast recording apparatus, a broadcast recording and reproducing apparatus, and a recording medium that can flexibly cope with a high broadcast.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a digital broadcasting system will be briefly described before describing a recording method and a reproducing method according 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 one HDTV channel to three SDTV channels. Video / audio signal is MPEG-2
(MovingPicture E digital broadcast recording / playback pert Grou
p), and transmitted by TS (Transport Stream). In the case of SDTV 3 channel simultaneous broadcasting, the data of each channel is arranged in a separate TS respectively,
Which channel data is included in each TS is identified by data called PID (Program ID) of the TS header. For example, when the PID is 1001H (H: hexadecimal notation), the data of channel 1 is used. When the PID is 1002H, the data of channel 2 is used.
By determining the PID and the channel number in advance, such as the channel 3 data in the case of 003H, it is possible to determine how many channels of data are being received by the PID.

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

FIG. 1 is a conceptual diagram showing a first recording method and a reproducing method according to a broadcast recording / reproducing apparatus according to the present invention. The first recording method shown in FIG. 1 records a predetermined one of three channel contents broadcasted in a time-division manner. Specifically, when recording a broadcast stream in which channels 1 (11), 2 (12), and 3 (13) are continuously transmitted for each TS on a disc, the recording is performed while detecting the PID. For example, PID = 1001
H, that is, only the data of channel 1 is recorded in 14.
In addition, normal continuous reproduction is performed on the data 14 of channel 1 during reproduction of the disk recorded in this manner. That is, in broadcast, PID = 11001H, 1002H, and 1003H are sent, but at the time of recording, only the data of 1001H is recorded.

Incidentally, regarding the above-mentioned first recording method,
Only the data of PID = 1002H may be recorded.
Only the data of 1003H may be recorded. One program selected by the user is selected and recorded. Also, the user may select a genre. For example, if you select “News”, the time when the news is automatically broadcasted even if news is performed on channel 1 from 7:00 to 7:30 and from 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 a reproducing method according to the broadcast recording / reproducing apparatus according to the present invention. In the second recording method shown in FIG. 2, the data (21) of PID = 1001H is recorded in the area 1 (24) on the disc while the PID is detected, and the data (22) of PID = 1002H is recorded on the optical disc. And the data (23) of PID = 1003H is recorded in the area 3 (26) on the disc. That is, at the time of recording, for example, for each TS (region 1 (2
4) → Area 2 (25) → Area 3 (26) → Area 1 (2
4) → area 2 (25) → area 3 (26) →.

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

Although not shown, a part of a plurality of programs of all data, for example, data having a PID of 1001H is recorded in an area 1 on the disk, and data of 1003H is recorded in an area 2 on the optical disk. 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 record while jumping (→...), At the time of reproduction, only area 1 should be reproduced when reproducing channel 1 data, and only area 2 should be reproduced when reproducing channel 3 data. . This is because the number of jumps during playback is reduced as in the case described above,
Depending on the conditions, stable normal playback and retry can be performed, and special playback such as fast forward, which is a function unique to playback, and non-linear playback, which seamlessly connects streams at distant positions on the disc, can be easily performed. Become.

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

The transmission method may be such that the main content is not transmitted by the program 1, the additional content 1 is the program 2, the additional content 2 is not transmitted by the program 3, and the additional content 3 is not transmitted. The program 1 and the additional content 2 may be 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.

Hereinafter, the quiz program of the main content is program 1, the low level hint of the additional content 1 is program 2, the middle level hint of the additional content 2 is program 3, and the high level hint of the additional content 3 is program 3.
Inside private data.

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

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 input. It is displayed in the lower left half of the TV screen. From the remote control
When the hint "2" is input, the program 3 is played and the middle level hint is displayed at the center 1 in 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 a high-level hint is displayed on the lower right half of the TV screen. In this way, the viewer can enjoy the quiz program according to the knowledge level by selecting and displaying the favorite hint.

In the above-described third recording method and reproducing method, it is not always necessary to record all of the quiz program, the low-level hint, the medium-level hint, and the high-level hint.

Hereinafter, although not shown, a case where the quiz program of the main content is program 1 and the low-level hint of the additional content 1 is program 2 will be described. Upon receiving the broadcast, the quiz program is recorded as program 1 and the low-level hint is recorded as program 2. At the time of playback, 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 program is displayed in the upper half of the TV screen. When "1" is input from the remote control,
Program 2 is played and a low level hint is displayed, for example, in the lower half of the television screen. As described above, the viewer can enjoy the quiz program according to the knowledge level by selecting and displaying the hint.

Here, the control data for recognizing the contents of the broadcast as described above and for defining the recording / reproducing procedure will be described. Fig. 8 shows TS (Transport Packet)
FIG. 3 is a conceptual diagram showing the configuration of FIG. As shown in FIG.
sport Packet) is composed of header and payload.
The payload is a PSI packet composed of a PES packet in which video / audio data and the like are arranged, and other data.
It consists of one of the sections. The PSI section is
Data called PAT, CAT, PMT, etc., or Private s
section. The Private Section allows you to send freely available data.

In the above-described third recording method and reproducing method, various kinds of information are previously allocated to the Private section configured as described above. Specifically, Privat
In the upper two bits of the e section data, information indicating a program display mode is arranged, and (00: program display 01: program /
CM display). In the case of the program display (00), the information indicating the genre of the broadcast is arranged in the next 4 bits, and is set to (0000: quiz program 0001: foreign language conversation ...). In the case of a quiz program, information indicating the contents of the main stream of channels 1, 2, and 3 is arranged in the next 2 bits × 3. (00: quiz program 01: low-level hint 1)
0: medium level hint 11: high level hint). The next 2 bits × 3 include channel 1,
Information indicating the contents of the contents in a few private streams is shown, and is set to (00: quiz program 01: low-level hint 10: medium-level hint 11: high-level hint. The present invention is not limited to the specific example described above, and other contents may be used as long as the contents of the channel are known.

FIG. 4 is a conceptual diagram showing a fourth recording method and a reproducing method according 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 in accordance with the conversation ability level of the user. In digital broadcasting, for example, an English conversation program of the main content is transmitted as a program 1 (41), and a speed magnification of level 1 at which the user speaks a little slowly is set as a program 2 (42).
Is transmitted as additional information, and the level 2 speed magnification of speaking very slowly
It shall be transmitted as additional information in 3).

Specifically, in the program 2 (42),
In the program 1 (42), a speed magnification, for example, a value such as 0.9 is transmitted only while the English teacher is speaking. Note that a value such as 10 is transmitted by the program 2 (42) because it is not thrown in Japanese commentary other than English and commercials. In the program 3 (43), a speed magnification, for example, a value such as 0.7 is transmitted only while the English teacher is speaking. In the case of Japanese commentary other than English, commercials, etc., a value such as 10 is used for program 3 (4
Sent in 3).

When a broadcast is received, recording is performed in the fourth recording method in the same manner as in the above-described second and third recording methods. That is, an English conversation program is recorded as program 1 in the area 1 (44) on the disk, the speed magnification of level 1 is recorded as program 2 in area 2 (45), and the speed magnification of level 2 is recorded as program 3 in area 3 (44). 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 magnification is program 2, and the level 2 speed magnification is recorded as program 3. I 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 reproduced at normal speed.

Then, "speed", "
When "1" is input, program 2 is reproduced and the speed magnification of the English conversation program is analyzed. If the magnification is 0.9, the reproduction speed is reduced to 0.9 times only that part, and if the magnification is 10, the reproduction speed of that part is reduced. When the "speed" and "2" are input from the remote controller, the playback speed is returned to 10. The program 3 is played and the speed ratio of the English conversation program is analyzed. The speed drops to 0.7 times, and if the magnification is 10, the speed of that part returns to 10 times.

As described above, the viewer can freely select the conversation speed according to the English ability and carry out the language learning only by operating the remote controller. Note that there is also a method of inputting the speed magnification information itself from the remote controller using the ten keys. In this case, a numerical value other than 10 is temporarily replaced with the input numerical value among the recorded speed magnifications. Since the speed magnification information has a very small information amount, it is generally transmitted not as a program but as private data in a gap in the program 1. In such a case, it is also 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. Further, the level of the speed magnification is not limited to the two types of 1 and 2 as described above, but may be a plurality of levels.

Here, 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 information is allocated in advance to the Private section. Specifically, the top 2 of Private Section data
In the bits, information indicating the program display mode is arranged, and (0)
0: 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. (0000: quiz program 0001: foreign language conversation 0002:...)
It has been. In the case of a foreign language program, information indicating the language is arranged in the next 4 bits.
0001: German 0002: French ...
・ ・).

As described above, in the next two bits in which the predetermined information is allocated, information indicating the contents of the subsequent 8 bits for channel 1 is allocated, and (00: foreign language program 0)
1: Speed magnification 10: Interval time
...). When the previous two bits are 00 for channel 1, the next 8 bits are 00
In the case of H, 01 to 10, information indicating a speed magnification or an interval time is arranged.

As described above, information indicating the contents of the subsequent 8 bits is allocated to the next 2 bits in which the predetermined information is allocated. For channel 2, (00: foreign language program 01: speed magnification) 10: Interval time ・
・ ・ ・ ・ ・) Then, in the next 8 bits, for channel 2, when the previous 2 bits are 00,
At 00H, 01 to 10, information indicating a speed magnification or an interval time is arranged.

Further, as described above, in the next 2 bits where the predetermined information is allocated, information indicating the contents of the subsequent 8 bits for channel 3 is allocated. (00: foreign language program 01: speed magnification) 10: Interval time
...). Then, for the next 8 bits, for channel 3, when the previous 2 bits are 00,
At 00H, 01 to 10, information indicating a speed magnification or an interval time is arranged. Note that the correspondence relationship of this information is not limited to the specific example described above, but may be any other information as long as the contents of 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 a reproducing method according to the broadcast recording / reproducing apparatus according to the present invention. In this case, in a foreign language conversation program or the like, the other party can speak after the other party speaks, and the interval length can be changed according to the conversation level of the user. In digital broadcasting, for example, level 1 in which an English conversation program of the main content is transmitted as a program 1 (51) and takes an interval of a normal length.
Is transmitted as additional information in the program 2 (52), and the level 2 interval time, which is a longer interval, is obtained in the program 3 (5).
It is assumed that the information is transmitted as additional information in 3).

Specifically, in the program 2, when the English teacher has finished speaking, an interval time having a normal length, for example, a value such as 3 indicating 3 seconds is transmitted.
Nothing else is transmitted. In the program 3, when the English teacher has finished speaking, a longer interval time, for example, a value such as 6 indicating 6 seconds is transmitted. Nothing else is transmitted.

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

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

When "interval time" and "1" are inputted 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 for 3 seconds is reproduced. An outage is performed. When "interval time" and "2" are input from the remote controller, the program 3
Is reproduced and the interval time of the English conversation program is analyzed, and if the interval time is 6, the reproduction stop for 6 seconds is executed in that part.

As described above, the viewer can perform language learning by freely selecting the interval time for himself / herself to speak based on his / her English ability only by selecting with the remote control.

It is also possible to broadcast German conversation and interval time information with the program 3, and French conversation and interval time information with the program 3. In addition, the level of the interval time is not limited to the two types 1 and 2 as described above, and may be a plurality of levels.

FIG. 6 is a conceptual diagram showing a sixth recording method and a reproducing method according to the broadcast recording / reproducing apparatus according to the present invention. In this case, in paid programs, etc., viewers who have not paid the viewing fee or have paid a low viewing fee have the CM recorded / reproduced and paid the viewing fee, or For viewers who pay a high viewing fee, it is possible to cut / record / reproduce commercials sandwiched between contents. Also, in digital broadcasting, for example, a program and a CM
1), and the CM timing information is transmitted as additional information in the program 2 (62). In FIG. 6, in the portion indicated by 63,
Another program is sent.

Specifically, in the program 1 (61),
A normal program is broadcast. CMs are also included in them, and as a recent tendency, there is an overlapping program portion of several seconds to several tens of seconds immediately before and after the CM. In the program 2 (62), as the control data, a CM portion and a flag indicating an immediately preceding portion or a portion immediately after the overlapping program portion of several seconds to several tens seconds immediately before and after the CM are transmitted. However, the program 2 may be scrambled. In this case, the data is data that can be decrypted only by a subscriber or a viewer who pays a viewing fee or pays a large viewing fee.

When a broadcast is received, in the sixth recording method, recording is performed without being divided for each channel, as in the first recording method described above. First, the broadcast recording / reproducing apparatus recognizes from the control data that a normal program is recorded as the program 1 (61), and one side of the CM and the program overlapping part is recorded as the program 2 (62). Normally, a non-subscriber, a viewer who has not paid the viewing fee, or a viewer who has paid a low viewing fee cannot record the program 2, and therefore, records the program 1 as it is in the area 64, and discards the information of the program 2. I do. On the other hand, the contractor or the viewer who pays the viewing fee or pays a high viewing fee can decode the program 2 and understand the flag indicating the portion of the CM and the program overlapping portion on one side. be able to. As a result, of the program 1, the CM and the program overlapping portion are automatically cut and recorded in the recording device. Since the information of the program 2 is unnecessary thereafter, it is discarded without recording.

Therefore, at the time of reproduction, a program and a CM are reproduced for a non-subscriber, a viewer who has not paid a viewing fee, or a viewer who has paid a small viewing fee. In addition, only the program is reproduced for a subscriber or a viewer who has paid a viewing fee or has paid a large viewing fee.

As described above, a subscriber or a viewer who has paid a viewing fee or has paid a large viewing fee is
It is not necessary to watch the CM and the program overlapping part, and the program part can be viewed. It should be noted that since the flag indicating the part on one side of the CM and the program overlapping part has a very small amount of information, it is general that the flag is transmitted not as a program but as private data in a gap in the program 1. In such a case, it is possible to broadcast another program by the program 1, the program 2, and the program 3.

Here, control data for recognizing the contents of the broadcast and for defining the recording / reproducing procedure will be described. In the above-described sixth recording method and reproducing method, various information is allocated in advance to the Private section. Specifically, the top 2 of Private Section data
In the bits, information indicating the program display mode is arranged, and (0)
0: program display 01: program / CM display). In the case of program / CM display (01), the next two bits include
A program / CM flag is arranged, and (00: program 01: CM ...
...). Note that the correspondence relationship of this information is not limited to the specific example described above, and may be other information as long as a distinction is made between a program and a CM.

FIG. 7 is a conceptual diagram showing a seventh recording method and a reproducing method according to the broadcast recording / reproducing apparatus according to the present invention. In this case, in paid programs, etc., viewers who have not paid the viewing fee or have paid a low viewing fee have the CM recorded / reproduced and paid the viewing fee, or A viewer who pays a high viewing fee can cut a CM sandwiched between contents and record / reproduce it. In digital broadcasting, for example, a program and a commercial
It is assumed that the CM 2 is transmitted in (71) and the CM timing information is transmitted as additional information in the program 2 (72).

Specifically, in the program 1 (71),
A normal program is broadcast. CMs are also included in them, and as a recent tendency, there is an overlapping program portion of several seconds to several tens of seconds immediately before and after the CM. Program 2 (7
In 2), a flag indicating a portion immediately before or immediately after the CM portion and a program portion overlapping several seconds to several tens of seconds immediately before and after the CM is transmitted. However, the program 2 may be scrambled, and has data that can be decrypted only by a subscriber or a viewer who pays a viewing fee or pays a large viewing fee.

When a broadcast is received, recording is performed in the seventh recording method in the same manner as in the above-described second to fifth recording methods. That is, a normal program including a commercial is program 1
Is recorded in the area 1 (74) on the disc, and a flag indicating one side of the CM and the program overlapping part is recorded in the area 2 (75) as the program 2.

At the time of reproduction, first, the broadcast recording / reproducing apparatus reads a normal program from the control data,
And that one of the program overlapping portions is recorded as program 2. Next, the program 1 is reproduced, and a normal program including the CM is displayed on the television screen. In addition, usually, non-subscribers, have not paid the viewing fee,
Or for viewers who pay a small fee,
Because program 2 cannot be decoded,
CM is played. On the other hand, for subscribers or viewers who pay the viewing fee or pay a large viewing fee, the program 2 is played and the flag indicating one side of the overlapping portion of the CM and the program is decoded. Is done. As a result, the CM and the program overlapping part are automatically skipped and are not reproduced.

As described above, a subscriber or a viewer who has paid a viewing fee or has paid a large viewing fee is
It is not necessary to watch the CM and the program overlapping part, and the program part can be viewed. It should be noted that since the flag indicating the part on one side of the CM and the program overlapping part has a very small amount of information, it is general that the flag is transmitted not as a program but as private data in a gap in the program 1. In such a case, it is possible to broadcast another program by the program 1, the program 2, and the program 3.
