This flowchart shows the operation of the receiving apparatus 1 when the viewer selects a broadcast program search mode prepared in advance by operating the operation key unit 13 or the remote controller unit 17.

The receiver 1 starts its operation when the broadcast program search mode is selected, and the tuner 3 receives the broadcast radio wave of the leading frequency of the plurality of frequencies stored in advance (step SA1). Next, by analyzing the TS (transport stream) signal extracted from the received signal, program sequence information including information such as service ID (channel number), service name (channel name), and program name included in each service is obtained. It is received (step SA2). The program arrangement information corresponds to the identification information in the present invention. Subsequently, after starting reception of the first program (first channel program) based on the service ID (step SA3), the type of the relevant program (service) based on the service list descriptor added to the program element signal of the first program. Check (Broadcast system).

If the program type is "television type" (YES in step SA4), the program is SDTV (standard definition television) based on the component descriptor added to the program element signal. It is confirmed whether or not the data is (step SA5). At this time S
If it is DTV data (YES in step SA5),
Upon receiving the program element signal (step SA6), the broadcast station name and still image data generated from a part of the program data (moving image information) are accumulated in the auxiliary storage device 12 as the program information of the SDTV category (step S6). SA7), S
If it is HDTV data instead of DTV (step S
(NO in A5), the program element signal is received (step S
A8), the broadcast station name, and still image data generated from a part of the program data (moving image information) is stored in the auxiliary storage device 12 as program information of the HDTV category (step SA
9). In the present embodiment, the above service I
D, the service list descriptor, and the component descriptor are the identification information in the present invention.

On the other hand, if the program type is "television type" instead of "television type" (NO at step SA4, YES at step SA10), the program element signal is received (step SA11), and the broadcasting station name is set. The program information of the audio category is stored in the auxiliary storage device 12 (step SA1
2) If the program type is "data type" (steps SA4 and SA10 are NO, step SA13 is YE)
S), and receives the program element signal (step SA1
4) The still image data generated from the broadcasting station name and part of the program data is stored in the auxiliary storage device 12 as program information of the data category (step SA15). Here, when accumulating each program information described above, data necessary for receiving the program such as a reception frequency (broadcast frequency) and a service ID at that time are stored in the auxiliary storage device 12 in association with the program information. .

Subsequently, when the accumulation of the above-mentioned program information for the first program is completed, the program (channel) is changed (NO in step SA16, step SA17), the process returns to step SA4, and the same processing is performed for the other programs. repeat. Further, when the program information of the last program provided on the same frequency (the program being broadcast on the last channel) has been stored (YES in step SA16).
S), this time after changing the reception frequency (step SA1
If NO in step S8, step SA19), the process returns to step SA2 to acquire new program arrangement information, and the processes up to step SA17 are repeated. Then, when the accumulation of the program information is completed for all the programs (programs of all channels) that can be received at the last frequency (YES in step SA18),
The program information accumulated in the auxiliary storage device 12 is displayed as a list on the screen of the display device 9 in the form of the program list screen 100 shown in FIG. 3 (step SA20).

That is, in the present embodiment, the broadcasting system (“HDTV” to “audio broadcasting” in the figure) is displayed at the left end of the screen.
Are displayed side by side in the vertical direction, and on the right side, a small screen (still image 1, still image 2, still image 3, ...) that is a reduced still image of each program with the same broadcasting system (broadcast mode) is displayed horizontally. Each program (small screen) is displayed by displaying it side by side and displaying the name of the broadcasting station (broadcasting station 1, broadcasting station 2, broadcasting station 3, ...) under each small screen. The list is displayed in association with the type (category) of. However, regarding the display of the program of "audio broadcasting" in which the program information accumulated in the auxiliary storage device 12 does not include the still image data, the broadcast station name is displayed in a square frame instead of the small screen.

Thus, in the present embodiment, the viewer immediately confirms which program is provided by which broadcasting station when confirming the program currently being broadcast (viewable program). I can know. At the same time, it is possible to know what kind of broadcasting system those programs are based on. As a result, for example, when the terrestrial wave and the satellite are exactly the same, it is possible to select the program with the better image quality by checking the broadcasting system. That is, when the same program is performed on the HDTV and the SDTV, it is possible to determine the difference in image quality between the programs even if the programs are displayed on the program list screen 100 in a small screen. As a result, although the broadcast of good image quality is being performed, the broadcast of bad image quality (SDT
V) will not be selected and received.

In the present embodiment, the program,
Although the list is displayed so that the relationship between the broadcasting station and the broadcasting system can be understood, the broadcasting station may be omitted and displayed. In addition to the character string, a mark prepared in advance may be displayed as the broadcasting station name and the broadcasting system, and the broadcasting station logo mark or the channel number may be used as the broadcasting station name. FIG. 4 shows another program list screen 110 showing a display form in which the above-mentioned broadcasting station name is omitted, and as shown in FIG.
Display a small screen of each program in order of reception or channel,
You may make it display by making each small screen correspond to a broadcasting system. In the illustrated example, the program name is acquired and stored as the program information described above, and the program name is displayed instead of the small screen for the program having no image data. Here, if it is distinguished from other programs which are "audio broadcasting", arbitrary characters or marks may be displayed instead of the program name.

Further, the program information or the like stored in the auxiliary storage device 12 for each category cannot be ensured to be consistent with the actual broadcast after a certain amount of time has passed, and need not be stored. Therefore, after the program list is displayed, the program information or the like may be automatically deleted at the time when a predetermined time has elapsed. Further, the viewer may be allowed to freely set the predetermined time.

Further, in the present embodiment, the receiving unit 4
Since only one (tuner 3) is installed, it has been unavoidable to simultaneously display a plurality of still images obtained by serially switching and receiving a plurality of programs. By installing 3), a plurality of programs can be received in parallel, and a plurality of moving images can be displayed simultaneously.

Next, the operation of the receiving apparatus 1 according to the present invention when the viewer selects a program after displaying the program list in the broadcast program search mode described above will be described with reference to the flowchart of FIG.

In the receiving device 1, after the program list screen 100 is displayed by the procedure described above (step SB1), when the viewer operates the cursor key of the remote control unit 17 (or the touch panel of the main body of the device). (YES in step SB2), and accordingly, the cursor (not shown) previously displayed on the program list screen 100 is moved to a predetermined small screen (step SB3). Then, the auxiliary storage device 1 stores the small screen of the moving destination, that is, the broadcast frequency, the service ID, etc. regarding the TV program designated by the user.
Then, the tuner 3 starts receiving the program, and the still image of the small screen is switched to the moving image of the current broadcast content and displayed as a moving image while the small image is read (step SB4). When the program to which the cursor is moved is an audio broadcast, the audio information received with the screen displayed is decoded by the audio decoder 8 and output from the audio output device 10. And either TV
When the viewer operates the enter key while the program is in the selected state (NO in step SB2, YE in SB5).
S), the small-screen moving image is switched to full-screen display (original size), and the program is displayed in the normal program viewing state (step SB6). Then, after this, the program is continuously displayed until the return key for reselecting the program is operated by the viewer, and when the return key is operated (step SB7), the program list is displayed again ( Step SB1) and the above-described operation is repeated.

As a result, when a viewer selects a program, the still image of the selected program is automatically switched to a moving image if he / she selects an arbitrary program without performing an operation of enlarging and displaying the program. The specific program contents can be confirmed by. Therefore, it is not necessary to re-display the program list screen 100 (screen for selection) each time when selecting a program to watch or reselecting another program. This also improves the operability when selecting a program.

In the present embodiment, when the viewer moves the cursor, reception of the program of the moving destination is immediately started, and the still image on the small screen is switched to the moving image display of the current broadcast content. Although the configuration is adopted, such a moving image display may be started by waiting for a predetermined key operation by the viewer, or the cursor may be moved for a fixed time (for example, 1 or 2 seconds).
You may confirm that it will not be moved and then try again. In that case, it is possible to eliminate useless reception operation of the program.

When the program list screen 100 is displayed again, for example, if a predetermined time has not passed since the previous display, the program list screen 100 is redisplayed using the program information stored in the auxiliary storage device 12. When the predetermined time has passed, if the program information is newly stored and redisplayed based on it, the program list screen 100 can be displayed by eliminating the unnecessary storage operation of the program information. Can be shortened in time. Also, in that case, for example, between the previous display and the current display, "1:00", "2:00"
When it is possible to judge that there is a high possibility that the program content has switched, such as when the hour arrives every time, new program information is always stored even if the predetermined time has not elapsed. If so, the program list screen 10
It is possible to reliably maintain the consistency between 0 and the actual broadcast. Further, for example, in step SA2 of the program search operation described with reference to FIG. 2, when the TS signal is analyzed and the program arrangement information is received, the information on the broadcast date and time of the program at each broadcasting station (channel) is also received and stored. Well,
Based on the information, if there is a program switched from the previous display to the current display, a new program information accumulation operation is performed for that program, which also causes the program list screen 100 and the actual broadcast to be displayed. Consistency can be reliably maintained.

(Second Embodiment) Next, the second embodiment of the present invention will be described.
An embodiment will be described. The present embodiment is the same as the first embodiment in the receiving device 1 having the same configuration as that shown in FIG.
The control program for performing the operation in another broadcast program search mode different from that of the embodiment is stored in the main storage device 11.

That is, FIG. 6 is a flow chart showing the operation of the receiving apparatus 1 in the present embodiment in the broadcast program search mode, in which the receiving apparatus 1 has a predetermined operation key portion 13 or remote control unit 17 by the viewer. The operation is started in accordance with the operation, and first, the category selection screen 120 for selecting the broadcasting system as shown in FIG. 7 is displayed on the screen of the display device 9 to allow the viewer to select the type.
The selected category is stored (step SC1).
Next, similarly to steps SA1 to SA3 of the first embodiment, after receiving the broadcast radio wave of the leading frequency and analyzing the TS signal extracted from the received signal to receive the program arrangement information, Start reception (step SC2)
~ SC4).

Then, it is determined whether or not the type of the program indicated by the service list descriptor added to the received program element signal of the first program matches the category of the category selected in step SC1 ( Step SC
5). If the categories match here (step S
If the selected category is not the TV type (“HDTV” or “SDTV”), that is, if the selected category is “data broadcasting” or “audio broadcasting” (NO in step SC6), the corresponding The program element signal of the program is received, and if the broadcasting station name and the image data are included, the still image data is stored in the auxiliary storage device 12 as the program information (step SC7). On the other hand, when the selected category is the TV type (Y in step SC6
ES), and further determines whether or not the type of television broadcast indicated by the component descriptor added to the received program element signal matches the selected category (step SC8). Then, for example, the received program is “SDTV” and the selected category is “HDT”.
If the type of TV broadcast does not match the selected category (NO in step SC8), as in the case of "V", the process proceeds to step SC10 without doing anything, for example, both are "HDTV". If they match (YES in step SC8), the program element signal of the program is received, and the broadcast station name and program data (video information)
Still image data generated from a part of the above is stored in the auxiliary storage device 12 as program information (step SC9).

Subsequently, when the above process for the first program is completed, the program (channel) is changed (step SC
If NO in step 10, step SC11), the process returns to step SC5 to repeat the above process for other programs. When the above process is completed for the last program provided on the same frequency (the program being broadcast on the last channel) (YES in step SC10), this time the reception frequency is changed (NO in step SC12). , Step SC13),
Return to step SC3 to acquire new program arrangement information,
The processing up to step SC10 is repeated. Then, when the processing for all programs (programs of all channels) receivable on the last frequency is completed (YES in step SC12), the program information accumulated in the auxiliary storage device 12, that is, the broadcast selected by the viewer. Information about programs that are in the category and are being broadcast at that time is displayed as a list on the screen of the display device 9 in the form of the program list screen 120 for each broadcast category shown in FIG. 8 (step SC1
4).

FIG. 8 is a program list screen 120 for each category when the category selected by the viewer is "HDTV", which is a small screen obtained by reducing the selected category and the still image extracted from each program data. (Still image 1, still image 2, still image 3, ...), and the broadcast station name (broadcast station 1, broadcast station 2,
Broadcast station 3, ...) is displayed. If the category selected by the viewer is “audio broadcasting” or the like and there is no still image data, instead of the small screen as shown in FIG. 3 in the first embodiment. Displays the broadcasting station name in a square frame.

As a result, in the present embodiment, the viewer performs a program search to find only the program currently being broadcast (viewable program) and the program of the specific broadcasting system selected by himself / herself. You can know immediately. Therefore, when the viewer wants to watch only a program that is broadcast in good image quality, he / she can immediately select and watch such a program.

Also in this embodiment, when the viewer operates the cursor to select one of the programs while the category-based program list screen 120 is displayed in the broadcast program search mode described above. The same operation as that described in the flowchart of FIG. 5 in the first embodiment is performed. Therefore, as in the first embodiment, the operability when selecting a program is improved. Since the details of this operation are exactly the same as those in the first embodiment, further description will be omitted.

In the present embodiment, when the operation is started in the broadcast program search mode, the viewer is allowed to select the desired broadcast system first, and then the program information of the corresponding program is stored. However, you may do as follows. That is, first, by the same operation as the operation in the broadcast program search mode described in the first embodiment, after the program information regarding all the programs being broadcast at that time is accumulated in the auxiliary storage device 12, the viewer Let the user select the desired category. Then, only the program information of the selected category may be read and displayed as the category-based program list screen 120. In that case, the program reception time at the beginning of the operation will be longer, but when the category of the program is changed by the viewer,
In particular, even when it is continuously performed, it is possible to instantaneously deal with it.

In the present embodiment, the receiving unit 4
Since only one (tuner 3) is installed, it has been unavoidable to simultaneously display a plurality of still images obtained by serially switching and receiving a plurality of programs. By installing 3), a plurality of programs can be received in parallel, and a plurality of moving images can be displayed simultaneously.

(Third Embodiment) Next, the third embodiment of the present invention will be described.
