36 knows that the desired service SV11 is multiplexed on the transport stream TS1 currently being received. That is, the CPU 36 advances the process from step S12 to S18.

In step S18, the acquired PA
Based on T, the packet ID of the PMT of the desired service SV11 is obtained. Here, “0x0011” is acquired (see FIG. 9). Next, the CPU 36 sets the packet ID “0x0011” of the PMT in the control data separation register of the TS decoder 26. According to this,
The PMT 1 of the service SV11 can be separated and its contents can be obtained in the memory 54 (step S19).

FIG. 10 shows the PMT1 of the service SV11. The CPU 36 selects a content included in the service SV11 based on the description of the PMT1 (Step S20).

FIG. 18 shows details of the content selection process. First, the CPU 36 acquires the area identification information 104 of the entire service from the description of the PMT 1 (FIG. 10).
Reference, step S201). Next, the nonvolatile memory 52
Then, the viewer area identification information is obtained (see FIG. 16, step S202). Further, based on the area identification information 104 and the viewer identification information, it is determined whether or not the viewer's area is a target area (step S203). This determination is made based on whether the bit of the area identification information 104 corresponding to the bit whose viewer identification information is “1” is “1” or “0”. If "1", it is determined that the area where the viewer lives is the target area, and if "0", the area is not the target area.

In the example shown in FIG. 10, since all regions are targeted, the process proceeds to step S204. Step S20
In step 4, the area identification information 102 of the first content is obtained from the description of the PMT1. In this example, the area identification information 102 of the video / audio data ES1101 (the weather forecast of the Hokkaido area) is acquired. Next, area identification information 1
Based on 02 and the viewer identification information, it is determined whether or not the content is a viewer's area as a target area (step S205). As described above, this determination is made based on whether the bit of the area identification information 104 corresponding to the bit whose viewer identification information is “1” is “1” or “0”.

If not, the area identification information 102 of the next content is obtained. In this example, the area identification information 102 of the video / audio data ES 1102 (weather forecast for the Tohoku area) is obtained. Then, it is determined whether or not the content is the viewer's area as the target area (step S205). Hereinafter, by repeating this process and finding the content that is the target area, step S2
Proceed to 08. In step S208, the packet ID of the content in the target area and the packet ID of the ECM
Recognize. In this example, the weather forecast for the Tohoku region is selected, and its packet IDs “0x0085” and “0x008”
6 ", and the ECM packet ID" 0x0082 "is obtained.

If the entire service is a broadcast limited to an area (see FIG. 13), it may be outside the target area in step S203. In this case, the CPU 3
6 controls the AV decoder 32 so as to display that the service is not suitable for viewing. Thereby, this display is made on the TV set 50. In this embodiment, only such display is performed, but the service content may be displayed together with such display.

As described above, the CPU 36 sets the packet ID “0x0085” “0x0” of the weather forecast for the Tohoku region.
086 "and the ECM packet ID" 0x0082 ". The CPU 36 sets the ECM packet ID “0x008
"2" is set in the control data separation register of the TS decoder 26 to acquire the ECM. Further, this ECM is given to the IC card 56 to obtain a restored scramble key. The scramble key thus obtained is set in the descrambler 58 (step S2 in FIG. 17).
1). Thereby, the video / audio data ES1101-ES1109 of all the contents of the service SV11.
Are in a descrambling state.

[0108] Further, the CPU 36 outputs the video data ES (V) 1102 and the audio data ES of the weather forecast in the Tohoku region.
(A) 1102 packet ID “0x0085” “0x”
0086 ”is set in an ES separation register (not shown) of the TS decoder 50 (step S22). Accordingly, the TS decoder 26 converts the separated video and audio data ES (V) 1102 and ES (A) 1102 into AV
Output to the decoder 32.

The AV decoder 32 having received this expands (decompresses) the compression and performs D / A conversion to generate a video composite signal. This signal is provided to the TV set 46 and output as video and audio. That is, the weather forecast for the Tohoku region is output.

As described above, it is possible to realize a broadcast for automatically selecting and outputting the contents suitable for the residence of the viewer.

In step S12, if the desired service is not multiplexed on the currently received transport stream, the process proceeds to step S13. In step S13, the NIT described in the PAT
Is obtained. Based on this, the NIT is acquired, and it is known which transport stream the desired service is multiplexed (steps S14 and S1).
5).

The CPU 36 switches the setting of the tuner 22 so as to receive the transport stream (step S16). Thereafter, the PAT of the transport stream is obtained (step S17). Thereafter, the above steps S18 and subsequent steps may be executed.

7. Other Embodiments 7.1. Display Method In the above embodiment, only contents in a suitable area are selected and output. However, in another embodiment, the content of the non-conforming area is temporally selected and automatically switched and displayed, so that the display time of the suitable area is increased and the display time of the other areas is shortened. Is also good. At this time, when another area is displayed, it may be displayed that another area is displayed.

In another embodiment, other regions may be displayed together on the same screen. In this case, as shown in FIG. 19, a suitable area may be displayed larger and other areas may be displayed smaller. In other areas,
Only character data, not images, may be displayed. Alternatively, the display of another area may be switched over time. In this way, the display of the other areas is not too small and is easy to see.

7.2. Setting method of area code In the above embodiment, the transmitting side sets the area code by setting bits corresponding to the prefecture as shown in FIG. Bits may be provided correspondingly.

When a zip code is used, FIG.
As shown in A, a bit may be provided corresponding to the first several digits (the first digit in the figure) of the postal code. Alternatively, as shown in FIG. 20B, the postal code of the target area may be sent as the area identification information.

In addition, other than the above, the country name, telephone number (country code,
Area number), latitude and longitude, and the like.

7.3. Other Service Examples In the above embodiment, the weather forecast has been described. In addition, the present invention can be applied to telephone shopping that introduces different products in different regions, news that distributes different information in different regions, advertisements with different contents in different regions, and broadcasting in different languages depending on countries.

The video and audio do not change depending on the region.
Only the subtitles may be changed. For example, the present invention can be applied to emergency bulletin subtitles (such as heavy rain warnings) that are only sent to the target area, and different subtitles for election bulletins.

C) Second Embodiment 8. Receiver FIG. 21 shows the overall configuration of a receiver 48 according to the second embodiment. In this embodiment, it is assumed that the receiving device 48 has a possibility that a viewing area of an in-vehicle television or the like may change in real time. GPS receiver 60 as position measuring means
Is supplied to the receiving device 48. The environment information conversion unit 35 of the restoration unit 49 receives the latitude / longitude signal and converts it into viewer area information in a format that can be compared with the area identification information from the transmission side. The reception control unit 36 selects a content based on the converted viewer area information. According to this embodiment, it is possible to automatically switch and display content contents suitable for the area where the user has moved.

FIG. 22 shows a hardware configuration when the receiving apparatus of FIG. 21 is realized using a CPU. A latitude / longitude signal from a GPS receiver 60 used in a car navigation system or the like is given to the CPU 36.
The CPU 36 receives the given latitude / longitude signal, determines which prefecture the latitude / longitude falls in, and converts it into viewer area information as shown in FIG. The CPU 36 stores the viewer area information obtained in real time in the memory 54 as described above.

The other processing is the same as in the first embodiment. That is, a suitable content is selected and output using the viewer area information.

In this embodiment, since the contents corresponding to the movement of a car or the like can be displayed, the present embodiment is suitable for broadcasting requiring strong locality and real time. For example, it is preferable to broadcast local traffic information for each area.

9. Other Embodiments 9.1. Area Identification Information In the above embodiment, the case where the area identification information is transmitted as an area code using bits for each prefecture has been described. However, if the area identification information is represented by latitude / longitude and transmitted, the receiving side can use the latitude / longitude information from the GPS as viewer area information without conversion.

9.2. Position Measuring Means In the above embodiment, the GPS receiving device was used as the position measuring means, but an output obtained by correcting the output of the GPS receiving device with gyro information may be used. Further, a PHS terminal device may be used as the position measuring means.

D) Third Embodiment A third embodiment is a case where the present invention is applied to a satellite broadcasting system having interactive properties.

10. Transmitting Apparatus FIG. 23 shows the configuration of the transmitting apparatus according to this embodiment.
In this embodiment, the navigation data management unit 17,
A navigation data generator 13 is provided. With these, navigation data for realizing interactivity is generated and multiplexed. Also,
In the above embodiment, the area identification information is added, but in this embodiment, the content identification information representing the content of the content is added by the content identification information management unit 19.

FIG. 24 shows the data structure of the transport stream generated by the above-mentioned transmitting apparatus. In the figure, the video ES (V) 11 of the service SV11,
Video ES (V) 12, Audio ES (A) 11, ES (A)
12 is shown, and the video and audio elementary streams of other services are omitted. Video and audio ES
11 is a TV shopping for furniture, and video / audio E
S12 is TV shopping for clothing. The two video / audio ESs can be interactively switched according to the operator on the receiving side based on the navigation data NVT1 and NVT2 that are interactive control data. Further, based on the navigation data NVT1 and NVT2, an additional display can be interactively changed according to the operation of the operator on the receiving side.

FIG. 25 shows the contents of PMT1 of service SV11. The control data PMT1 includes a packet I of each content (video, audio, navigation data).
D, a packet ID of ECM data for obtaining a key for descrambling the content is described. Further, in the first embodiment, the area identification information is described, but in this embodiment, the content identification information is described. In this method, the content is classified into a plurality of genres, and a bit is associated with each genre to form a content code. The creation format is the same as the area code in the first embodiment. In FIG. 25, the genre of the bit to which the content code “1” is added is displayed as the content identification information, but the content code is actually described. Video and audio ES, a TV shopping for furniture
11 is attached with content identification information of "interior", and the video / audio ES 12 which is TV shopping for clothing is attached with content identification information of "fashion".

Furthermore, since there are a plurality of contents for video, audio, and navigation data, the one to be output first is described as entry content. However, as described later, in this embodiment, the content that matches the viewer information is output with higher priority than the entry content. The packet ID of the control data PMT1 itself is “0x0011”.

FIG. 26 shows the contents of control data PAT. The control data PAT includes the services SV11 and SV multiplexed on the transport stream TS1.
12, PMT packet I for SV13 and SV14
D is described. Thereby, it is possible to know that the packet ID of the service SV11 is “0x0011”.

FIGS. 27 and 28 show the contents described in the navigation data NVT1 and NVT2. The set of navigation data NVT1 and NVT2 having the same contents is repeatedly transmitted. With the navigation data NVT1 and NVT2, it is possible to interactively change the service content as shown in FIGS. 29 to 32 according to the operation of the operator. The details will be described later.

11. Receiving Apparatus FIG. 33 is a block diagram showing a receiving apparatus according to the third embodiment. The CPU 36 controls each unit according to a program recorded in the memory 54. In the non-volatile memory 52, a genre in which the viewer is interested is stored by the viewer as viewer interest information. This viewer interest information can be coded and stored by the same method as the viewer area information in the first embodiment. Although only one area is selected as the viewer area information, a plurality of genres can be selected as the viewer interest information.

Here, it is assumed that a transport stream as shown in FIG. 24 has been transmitted. Also,
The service SV11 includes video data ES (V) 11, E
S (V) 12, audio data ES (A) 11, ES (A)
12, the video data ES (V) 11 and the audio data ES (A) 11 are the contents of television shopping related to furniture, the video data ES (V) 12, and the audio data ES.
(A) 12 shall be the content of television shopping regarding clothing.

The reception processing program recorded in the memory 54 is shown in the flowchart of FIG.

The operation in the case where the command to switch to the service SV11 of the transport stream TS1 is given to the CPU 58 on the assumption that the service SV13 of the transport stream TS1 is currently received will be described below. The instruction to the CPU 36 is given from an operation panel or an operation remote controller. The operation input unit 38 shown in FIG. 33 is a light receiving unit that receives a command from the operation panel or the operation remote controller.

First, the CPU 36 sets a PAT packet ID in a control data separation register (not shown) of the transport decoder (TS decoder) 26.
The packet ID of the PAT is fixedly set to “0x0000”. Thereby, the TS decoder 50 records the content of the separated PAT in the memory 60 (step S11). The PAT describes a list of services multiplexed on the currently received transport stream TS1 (see FIG. 26). Therefore, CP
U36 knows that the desired service SV11 is multiplexed on the currently received transport stream TS1. That is, the CPU 36 advances the process from step S12 to S18.

In step S18, the acquired PA
Based on T, the packet ID of the PMT of the desired service SV11 is obtained. Here, “0x0011” is acquired (see FIG. 26). Next, the CPU 36
The packet ID “0x0011” of the TS decoder 26
Is set in the control data separation register. As a result, the PMT 1 of the service SV11 can be separated and its contents can be obtained in the memory 54 (step S1).
9).

FIG. 25 shows the PMT1 of the service SV11. The CPU 36 determines whether or not the service SV11 includes the navigation data NVT based on the PMT1 (that is, whether or not the service SV11 is an interactive service) (step S191). If the NVT is not included, the same processing as in FIG. 17 is performed, and the content of the service is output from the TV set 50 (steps S20, S21, S22).

If the NVT is included as shown in FIG. 25, the CPU 36 performs a content selection process (step S192). FIG. 36 shows a detailed flowchart of the content selection process. First, in step S1921, viewer interest information is acquired from the nonvolatile memory 52. Here, it is assumed that the genre of “fashion” is “1” in the viewer interest information.

Next, the CPU 36 acquires the content identification information of the content described first from the PMT 1. Here, “interior” is acquired for the contents of the telephone shopping of furniture (see FIG. 25). further,
It is determined whether any of the genres described in the content identification information matches any of the genres of the viewer interest information (step S1923). Here, since they do not match, “fashion” is acquired as content identification information on telephone shopping of clothing, which is the next content (step S1925). Since the content identification information matches the viewer interest information, the process advances from step S1923 to step S1926.

In step S1926, the packet ID of the matching content (here, the clothing shop) and the packet ID of the ECM are recognized. Here, the packet ID “0x0097” of the video data ES (V) 12,
The packet ID “0x009” of the audio data ES (A) 11
9 ", the packet ID of the navigation data NVT2
It recognizes “0x0093” and the packet ID “0x0082” of these ECM data.

If none of the contents match the viewer interest information, the flow advances from step S1924 to step S1927. In this case, the packet ID of the entry content and the packet ID of the ECM described in the PMT 1 are obtained.

As described above, the content to be displayed first is selected based on the viewer interest information and the content identification information.

Next, the CPU 36 checks the ECM packet I
D “0x0082” is set in the control data separation register of the TS decoder 26 to acquire ECM data.
Further, this ECM data is given to the IC card 56,
The scramble key restored by the C card 56 is obtained. The scramble key obtained in this way is
Set to the scrambler 58 (step S19 in FIG. 35)
3). Thereby, the video data ES of the service SV11
(V) 11, ES (V) 12, audio data ES (A) 1
1, ES (A) 12, navigation data NVT1,
The NVT2 packet is in a descrambling state.

[0146] The CPU 36 also outputs the video and audio data ES (V) 1 selected in step S192.
2. Packet ID “0x0097” of ES (A) 12
“0x0099” is set in the ES separation register (not shown) of the TS decoder 26 (step S19)
4). Thus, the TS decoder 26 converts the separated video and audio data ES (V) 12 and ES (A) 12 into
Output to the AV decoder 32.

The AV decoder 32 having received this expands (decompresses) the compression and performs D / A conversion to generate a video composite signal. This signal is provided to the TV set 50 and output as video and audio. Thus, it is assumed that a moving image of television shopping of clothing as shown in FIG. 29 is displayed. Button B at the bottom right of the screen
0, B1, and B2 are displayed by the following navigation data, and include video and audio data ES.
(V) 12 and ES (A) 12.

In addition, the CPU 36 determines in step S19
In step 4, the packet ID “0x0093” of the navigation data NVT2 is set in a control data separation register (not shown) of the TS decoder 26. Thus, the navigation data NVT2 is temporarily recorded in the memory 54. Here, it is assumed that the navigation data NVT2 as shown in FIG.

Subsequently, the navigation data thus recorded is interpreted and executed (step S19).
5).

FIG. 37 shows a flowchart of a program for interpreting and executing the navigation data recorded in the memory 60.

First, the navigation data NV shown in FIG.
The object index number “0” is read from the object table of T2, and a button is displayed on the screen based on the information indicated here (step S10).
01). That is, the X coordinate “500” and the Y coordinate “200”
The bitmap data shown in the bitmap table is displayed at the position. For the object with the index number “0”, it is determined in advance that a bitmap in a focused state is displayed. Therefore, here, the control is performed so that the data of the bitmap index number “1” (highlighting of “application for Osaka Center”) is displayed.

Specifically, the CPU 36 supplies the data of the bitmap index number “1” (highlighted “Apply to Osaka Center”) to the video compositing unit 32 c of the AV decoder 32. Thereby, the video synthesizing unit 3
2c generates image data in which a highlight display of “APPLY TO OSAKA CENTER” is superimposed on the video data ES (V) 12. Therefore, button B0 is displayed on TV set 450 as shown in FIG.

Similarly, the button B1 in FIG. 29 is displayed based on the information of the index “1” in the object table of the navigation data NVT2 in FIG. However, the data of the bitmap index in the normal state is displayed for those other than the object index “0”. That is, here, the display processing of “application for the Tokyo center” that is not highlighted is performed (step S1002).

In the same manner, display processing of button B2 "go to furniture shop" (non-highlighted display) in FIG. 29 is performed based on the information of index "2" in the object table (step S1002).

As described above, as shown in FIG.
A display in which the buttons B0, B1, and B2 are superimposed on the moving image of the product description is obtained. As is apparent from the screen, the button B0 “Apply for Osaka Center” is displayed as being selected. Correspondingly, the CPU 36
Stores that the object index “0” is the currently selected object.

Next, when the key 82 for moving the cursor downward is pressed from the remote control 78 (or the operation panel of the main body) shown in FIG. 38, the operation input unit 38 receives this key, and
Notify CPU36. The CPU 36 determines what the operation input is (step S1003), and if it is a “key for moving the cursor down”, the process proceeds to step S1004.

In step S1004, the number of the currently selected object is incremented according to the object table of the navigation data NVT2, and the object index "1" is set to the selected state. That is, for the object index “1”, a bitmap shown in the column of the focus state is displayed, and the other object indexes “0” are displayed.
For “2”, a bitmap shown in the column of the normal state is displayed.

Accordingly, the screen of the TV set 50 changes as shown in FIG. That is, the button B1 “Apply for Tokyo Center” is selected.

Further, when the operator presses the key 82 for moving the cursor downward, the screen display shows a state in which the button B2 "Go to clothing shop" is selected, as shown in FIG. When the key 80 for moving the cursor upward from the state shown in FIG. 31 is pressed, the screen display returns to the state shown in FIG.

In the above embodiment, only the operations of the up and down cursor keys 80 and 82 are shown. However, if the object indexes are arranged in a two-dimensional array, the operations are performed in consideration of the left and right keys 86 and 88. be able to.

In the state of FIG. 31, when the enter button 84 of the remote controller 78 is pressed, the CPU 36 proceeds to step S
The process advances from step 1003 to step S1005. In step S1005, the CPU 36 determines whether the navigation data NVT2
To obtain the handler index described in the handler field of the currently selected object index. Here, since the object index “2” is selected, the handler index “2” of the handler column is acquired.

Further, referring to the handler definition table, the script corresponding to the handler index "2" is extracted and executed (step S1006). here,
Get "go to contents (index 0)". go to cont
ents () is an instruction to switch to a content having an index number in () shown in the hyperlink table.
Therefore, switching to the content (TV shopping for furniture) with the hyperlink index “0” indicated in the hyperlink table is performed.

In the hyperlink index “0” of the hyperlink table, the packet ID “0x009” of each of the video, audio, and navigation data as the link destination is set.
6 "," 0x0098 ", and" 0x0092 ". The CPU 36 stores the packet ID “0x0096” and “0x009” in the ES separation register of the TS decoder 26.
8 ", and the packet ID" 0x0092 "in the control data separation register.

Thus, the video data ES (V) 11 and the audio data ES (A) 11 are output from the TS decoder 26 to the AV decoder. Therefore, TV set 50
Displays a moving image of television shopping of furniture as shown in FIG. 32 and outputs the sound.

The navigation data NVT1 shown in FIG. 27 is separated by the TS decoder 26 and recorded in the memory 54 instead of the navigation data NVT2. About this navigation data NVT1,
The process shown in FIG. 37 is performed, and buttons B10, B11, and B12 are displayed as shown in FIG.

When the operator presses the decision button 84 (see FIG. 38) in a state where the button “Apply for Osaka Center” B10 is selected as shown in FIG. 32, the purchase application for the product displayed on the screen is made. It can be performed. Hereinafter, the processing will be described.

When the enter button 84 is pressed, the CPU 36
Proceeds from step S1003 to step S1005. In step S1005, the handler index is acquired from the handler column of the currently selected index according to the object table of the navigation data NVT1 (see FIG. 27).
Here, since the object index “0” is in the selected state, the handler index “0” is acquired.

Next, the CPU 36 executes a script corresponding to the handler index “0” in the handler definition table. That is, send_string (index0, index2) is executed. The send_string (A, B) is a command for calling the telephone number at the index “A” in the character string table and transmitting the character string at the index “B”. Therefore, here
The CPU 36 acquires “06-6368-XXXX” corresponding to the character string index “0” in the character string table, and
3 by controlling the line communication unit 62 shown in FIG.
-XXXX ". This telephone number is the telephone number of the Osaka reception center of this TV shopping. When the line is connected, the CPU 36 sets “Product code: A-3” corresponding to the character string index “2” in the character string table.
95 ". At this time, the CPU 36 acquires an ID for specifying the purchaser from the IC card 56 or the memory 54, and also transmits this.

As described above, it is possible to selectively receive the content whose content matches the interest of the viewer.
Although not described above, in this embodiment,
Products described in the video data change over time. Therefore, corresponding to this, navigation data having different contents (different product codes of the index “2” in the character string table) are transmitted. At this time, PMT1
, The content can be automatically switched to the content that matches the interest of the viewer.

12. Other Embodiments 12.1. Display at the Time of Switching Content In the above embodiment, at first, content whose content matches the interest of the viewer is automatically displayed, and then the content is changed by the viewer's operation. Can be changed.
In this case, it may be displayed that the content changed from the automatically selected content is output.

12.2. Viewer Information In the above embodiment, viewer information is used as environment information.
Although the genre in which the viewer is interested is used as the viewer information, the age, gender, and the like of the viewer may be used. in this case,
The content identification information on the transmitting side may also be content corresponding to these.

[0172] The content of the viewer's contract (which service is paid for the viewing fee) may be used as the viewer information. For example, when displaying electronic program information,
Based on the contents of the contract, it is possible to display only the program of the contracted service or to display the program of the contracted service in a large size.

Further, as the environmental information, the local information used in the first embodiment can be used. According to this, it is possible to automatically match the screen displayed first such as the weather forecast that can be interactively switched to the viewer's area.

12.3. Applicable Content In the above embodiment, telephone shopping was described. However, the present invention can be applied to all the contents described in the first and second embodiments (including those described as other embodiments). .

This is particularly effective when changing the background music (BGM) according to the viewer's interest, changing the genre of the music to be downloaded, or changing the quiz or questionnaire contents according to the viewer's age. is there.

12.4. Change of Default In the examples shown in FIGS. 27 to 32, “apply to Osaka Center” is selected as the default for both the viewers in Osaka and the viewers in Tokyo. However, in another embodiment, using the viewer area information, the "Apply to the Tokyo Center" is provided to the viewers in Tokyo so that "Apply to the Osaka Center" is the default for viewers in Osaka. May be the default.

The packet ID of the matching data is obtained by comparing with the security code described in the content identification information of T1. CPU
36 sets the packet ID in the control data register of the TS decoder 26. Thus, only the stock information held by the viewer is separated by the TS decoder 26 and stored in the memory 54. The CPU 36 reads the separated stock information from the memory 54 and outputs it to the personal computer 51 via the terminal P2.

Upon receiving the stock information, the personal computer 51 performs various processes in accordance with the stock processing program. For example, profit or loss can be displayed based on the current price included in the stock information and the purchase price and quantity stored in the hard disk. Further, it is also possible to display (output) advice on sale for each issue, taking into account past stock price movements included in the stock information.

15. Other Embodiments In the above embodiment, the stocks held by the viewer are used as the viewer information. However, the stocks which the viewer is interested in are used as the viewer information, and these stocks are used. Data may also be output to the personal computer 51. Thus, based on the desired purchase price set on the personal computer side and the current price of the acquired stock, advice on stock purchase is given to the personal computer 5.

F) Fifth Embodiment 16. Reception / Recording / Reproducing Apparatus This embodiment shows a receiving / recording / reproducing apparatus capable of recording and reproducing a received transport stream on a recording medium. Hereinafter, for convenience of explanation, the service SV of the transport stream TS1 according to the first embodiment will be described.
Although the case of receiving, recording, and reproducing 11 is described as an example, reception, recording, and reproduction can be similarly performed for each service of the transport stream according to the other embodiments described above.

FIG. 45 shows the overall configuration of a receiving, recording and reproducing apparatus according to this embodiment. The radio wave captured by the antenna 20 is demodulated by the receiving unit 22 as one transport stream. In the receiving mode, the transport stream from the receiving means 22 is provided to the restoring means 49. The restoration means 49 selects a packet related to a desired service from the transport stream, and restores and outputs a service content signal (for example, a composite signal such as NTSC) according to the content of the packet. Note that the restoration means 49
In the reception mode, using the environment (viewer area information in the first embodiment) stored in the environment storage unit 34 as the reception environment, the content is selected and the service content signal is output. That is, the reception environment is compared with the selection information (area identification information in the first embodiment) transmitted in association with the content, and the content having the matching selection information is selected as the service content signal. . The video / image output means 50 receives the service content signal and outputs a video and an image.

[0189] In the recording mode, the transport stream from the receiving means 22 is provided to the converting means 302. The recording data generating means 302 converts this transport stream into a packet multiplexed stream suitable for recording and outputs it as a converted stream.
The recording data generating means 302 selects a packet relating to a desired service from the transport stream, and selects only a packet necessary for reproduction from these packets to generate a converted stream. In this embodiment, when one service SV11 includes a plurality of video / audio data ES1101 to ES1109 as in the video / audio data ES11 of FIG. 11, all of them are recorded as converted streams.
The recording unit 304 stores the converted stream in the recording medium 30
Record in 8.

In the reproduction mode, the reading means 306 reads the converted stream from the recording medium 308. The read converted stream is provided to the restoration means 49. The restoration means 49 outputs a service content signal (for example, NTSC) according to the content of the converted stream.
Is restored and output. In the playback mode, the restoration unit 49 selects a content and outputs a service content signal using the environment (viewer area information in the first embodiment) stored in the environment storage unit 34 as a playback environment. I do. That is, the reproduction environment is compared with the selection information (area identification information in the first embodiment) recorded in association with the content, and the content having the matching selection information is selected as the service content signal. . The video / image output means 50 receives the service content signal and outputs a video and an image.

In this embodiment, a signal restored by the restoration means 49 is not recorded, but is recorded in a packet state. Therefore, it is possible to record including selection information such as area identification information.
Recording and reproduction can be performed without impairing the function of satellite broadcasting based on the selection information. Further, since both video and audio can be recorded in a digitally compressed state, the capacity of the recording medium can be effectively utilized.

Furthermore, since only packets relating to a desired service are selected from the transport stream and recorded, the capacity required for recording can be reduced. In addition, since the packets necessary only for reception are excluded from the packets and only the packets necessary for reproduction are selected and recorded, the capacity required for recording can be reduced.

16.1. Specific Configuration Example and Operation of Reception / Recording / Reproducing Apparatus FIG. 46 shows a receiving / recording / reproducing apparatus 300 shown in FIG.
FIG. 3 shows a block diagram in the case of realizing using U. The receiving / recording / reproducing apparatus 300 includes a receiving unit 310 and a recording / reproducing unit 31
2 is provided. The CPU 36 controls each unit according to a program recorded in the memory 54.

This device has three modes: a reception mode, a recording mode, and a reproduction mode. Hereinafter, the operation of each mode will be described.

(1) Reception mode The flowchart of the reception mode program recorded in the memory 54 is the same as that in FIG. 17 and the processing is the same, so that the description is omitted.

(2) Recording Mode FIG. 47 is a flowchart showing a recording mode program recorded in the memory 54. Steps S11 to S
22 is the same as the reception mode. Therefore, FIG.
In FIG. 7, only steps after step S23 are shown. When a recording command is given from the operation input unit 38, a recording mode is set. Hereinafter, a case where the video / audio data ES11 of the service SV11 of FIG. 11 is recorded will be described.

First, in step S23, the CPU 3
Reference numeral 6 denotes a video / audio data ES1101, ES1102,... ES110 of a desired service SV11 in a recording data separation register (not shown) of the TS decoder 26.
9, the packet ID of the NIT, the packet ID of the PAT, and the packet ID of the PMT1 of the desired service SV11 are set. Thereby, the TS decoder 26
Are video and audio data ES (V) 1101, 110
2 ... 1109, ES (A) 1101, 1102,.
Output 1109, PAT, PMT1, and NIT to the converted stream generation unit 314 of the recording / reproduction unit 312 in the packet state.

The CPU 36 determines whether the PM recorded in the memory 54
T1 is acquired, and only the information on the desired service SV11 is selected from the described information, and the converted PMT1 is selected.
Is generated (step S24). For example, among information included in the PMT1, the packet ID of the ECM is unnecessary because it is unnecessary at the time of reproduction. As a result, the converted PM from which the information not related to the recording and reproduction of the desired service SV11 is removed from the information included in the PMT1.
T1 is obtained.

Next, the CPU 36 generates control data SIT describing information of services and events (programs) contained in the converted stream to be recorded (step S).
25).

The CPU 36 supplies the converted PMT1 and SIT generated as described above to the MPU 316. MPU
316 gives this to the conversion stream generation unit 314,
Generate a conversion stream.

The converted stream generation unit 314 receives the PAT from the TS decoder 26 and receives the desired service SV1.
Generate a transformed PAT containing only information about
With the conversion PAT. At this time, the packet ID of the NIT included in the PAT is changed to the packet ID of the SIT. Also, the PMT from the TS decoder 26 is
Replace with the converted PMT received from U316. further,
The NIT from the TS decoder 26 is replaced with the SIT received from the MPU 316.

In this way, the ES of the desired service,
A packet-multiplexed conversion stream of SIT, conversion PAT, and conversion PMT is obtained.

[0203] The CPU 36 gives a recording command to the MPU 316 (step S27). In response, MPU31
6 controls the recording / reading unit 318 to
8, the converted stream is recorded. FIG. 48 schematically shows the recorded conversion stream.

When a recording stop command is given from the operation input unit 38, the CPU 36 gives this to the MPU 316 (steps S28 and S29). In response to this, the MPU 316 stops recording by the recording / reading unit 318.

In the conversion stream recorded on the magnetic tape 308, even if the control data has the same content, the data is multiplexed and recorded many times. Therefore, reproduction can be performed even from the middle of the magnetic tape.

If the selection of a service is changed during recording, the service changed halfway will be recorded. At this time, the conversion stream generation unit 314 detects that the information has become discontinuous (or
The control data DIT (Discontinuity Information Table) indicating the discontinuity of the information is generated based on the command from the H.36. Further, as shown in FIG. 49, this DIT is packet-multiplexed at the head of the changed service.
Similarly, when performing a new recording, this DIT
Is appended. DIT is also added when different programs in the same service are continuously recorded.

As described above, a service including a plurality of contents and describing the selection information in association with each content can be recorded on the magnetic tape 308 in a packet state. It should be noted that selection information is not described, and recording can be similarly performed for a service including a single content.

In the above description, the recording / reproducing apparatus 312 is provided with the conversion stream generating section 314, but the receiving apparatus 3
10 may be provided with this. In this case, the recording / reproducing device 312 records the converted stream output from the receiving device 310 as it is.

(3) Reproduction Mode FIG. 50 is a flowchart showing a reproduction mode program recorded in the memory 54. When a playback command is given from the operation input unit 38, the playback mode is set.

First, in step S31, CPU 536 gives a reproduction command to MPU 316. MPU31
6 receives this and controls the recording / reading unit 318 to read the converted stream from the magnetic tape 308. The read converted stream is provided to the TS decoder 26.

Next, the packet ID “0x00” of the converted PAT is stored in the control data separation register of the TS decoder 26.
Is set, the converted PAT is separated from the converted stream, and stored in the memory 54 (step S32). Based on the description of the converted PAT, the packet ID of the converted PMT
Is recognized (step S33).

Furthermore, the packet ID of the converted PMT is set in the control data separating register of the TS decoder 26, the converted PMT is separated from the converted stream, and stored in the memory 54 (step S34).

The contents of the converted PMT of the service SV11 are as follows:
This is the same as that shown in FIG. However, descriptions that are not necessary for reproduction of the ECM or the like are deleted. CPU36
Selects content included in the service SV11 based on the description of the converted PMT.

The content selection process is the same as the flowchart shown in FIG. As a result, content having an appropriate content according to the reproduction environment (here, the residence area of the viewer) is selected, and its packet ID is obtained. In the case where a service including a single content is reproduced without selection information being described, the content is automatically selected.

[0215] As described above, the CPU 36 obtains the packet ID of the selected content. The CPU 36
The packet ID of the selected video data ES (V) and audio data ES (A) is set in the ES separation register of the TS decoder 26, and these are separated from the converted stream. Separated video data ES (V) and audio data E
S (A) is output to the AV decoder 50.

[0216] Upon receiving this, the AV decoder expands (decompresses) the compression and performs D / A conversion to generate a video composite signal. This signal is provided to the TV set 50 and output as video and audio.

In this way, it is possible to automatically select and reproduce appropriate contents according to the region of the viewer.

If the CPU 36 finds the presence of DIT in the converted stream during reproduction, the CPU 36 returns to step S32 and performs the following processing of the converted PAT (step S3).
7). This is because DIT indicates a discontinuous point of recorded data.

When there is a reproduction stop command from the operation input unit 38, the CPU 36 gives this to the MPU 316 (steps S38 and S39). In response, MPU 316
Controls the recording / reading unit 318 so that the magnetic tape 308
Stop reading from.

In this embodiment, for a service including a plurality of contents, all contents are recorded. Therefore, at the time of reproduction, it is also possible to switch and display contents relating to other areas. Such content switching can be performed by, for example, a method as in the third embodiment.

16.2. Other Embodiments In the embodiment shown in FIG. 46, the TS decoder 26, the converted stream generator 314, and the CPU 36 (in particular, step S
24, S25), the recording data generating means 302
Has been realized. Further, the TS decoder 26 and the CPU
36 (especially, steps S32 to S36) implements the restoration means 49. Thus, the TS decoder 2
6 is shared by both the conversion means and the restoration means,
The configuration can be simplified.

In the embodiment of FIG. 46, the CPU 36 executes a part of the conversion stream generation (step S2).
4, S25), these processes may also be performed by the conversion stream generation unit 314. Further, although only the packet selected by the TS decoder 26 is provided to the converted stream generator 314, the transport stream from the descrambler 58 may be provided to the converted stream generator 314 as it is. In this case, the conversion stream generation unit 314 selects a necessary packet.

In FIG. 46, the receiving / recording / reproducing device 30
Although shown as 0, a receiving device including only the receiving unit 310 may be used. In this case, a recording data output terminal for extracting the output 26a of the TS decoder and a restoration data input terminal for receiving the converted stream 26b from the recording / reproducing unit 312 may be provided.

Further, a recording / reproducing apparatus including only the recording / reproducing section 312 may be used. Further, the recording / reproducing unit 312
Recording / reproducing unit 31 composed only of the reproducing function of
A recording device having only two recording functions may be used.

Further, in the above embodiment, descrambled data is recorded, but data in a scrambled state may be recorded.
In this case, the ECM data is also recorded. In this case, the ECM data may be recorded as it is,
It may be recorded as a part of the IT data.

In the above embodiment, all contents and selection information included in a desired service are recorded. However, as shown in FIG. 51, the recording data generation unit 302 may select a content at the time of recording based on the selection information and the environment information, and may record only information on the selected content. That is, in step S23 of FIG. 47, the PID of the selected content is set instead of the PID of all contents of the desired service. In this case, it is not necessary to include the selection information in the description of the converted PMT.

As described above, since only the information related to the selected content is recorded, the recording capacity of the recording medium 308 can be effectively used.

Further, as shown in FIG. 52, a selecting means 350 for switching between a full recording mode for recording all contents and a selective recording mode for selectively recording may be provided so that both modes can be switched. Selection means 350
Can be realized by the operation input unit 38 and the steps of a program that receives this input and determines whether to set the full recording mode or the selective recording mode.

In the above embodiments, a magnetic tape is used as a recording medium, but a recording medium such as a magnetic disk, a magneto-optical disk, and a semiconductor memory can be used.

G) Selection Information and Environment Information In each of the above embodiments, the selection information is described in the control data PMT, but may be described by providing separate and independent control data. 27 and 28 may be described in the navigation data. In any case, the selection information may be described anywhere as long as it is described in a state where the correspondence with the corresponding content is clearly defined.

As the selection information, the geographical position information and the information indicating the contents of the content have been exemplified, but the selection information may be time information. Accordingly, temporal information can be used as environmental information.

For example, selection information indicating that the content is suitable for viewing in the morning, selection information indicating that the content is suitable for viewing in the daytime, and information indicating that the content is suitable for viewing in the night are added. By doing so, it is possible to select the optimal content according to the environment of the receiving side. This is effective when broadcasting over a large range with a time difference. In addition, when recording and reproducing in the all recording mode by the receiving / recording / reproducing apparatus 300 in FIG. 46, it is possible to select appropriate contents according to the reproduction time.

When the selection information and the environmental information are not comparable, for example, when the selection information is a regional code of a prefecture and the environmental information is a postal code, one of them is made to be comparable. Or you need to convert both. For example, this can be realized by preparing a program for converting a postal code into a regional code.

H) Others The functions achieved by the program described above may be realized by the program alone.
Further, it may be realized in cooperation with an operating system such as TRON (trademark).

In each of the above embodiments, each processing program may be a program stored in the memory 54 in advance, or may be a program transmitted on a communication medium such as a communication line or a transport path. Is also good.

In each of the above embodiments, the CPU is used to achieve each function, but a part or all of the functions may be realized by hardware logic.
