When a match signal is given from the buffer 173, a channel voltage is generated according to the channel information given from the buffer 173, and outputted to the O1 to channel circuits 13 in FIG.

Next, the operation of the above practical example will be explained. Prior to the television program search operation, for example, one month's worth of television program information is read out from the Videotex information center using telesoft as shown in flowchart 1- of FIG. 16 to be memorized. That is, the user first performs J as shown in step A1 in FIG.
: Specify the videotex mode by key operation on the sea urchin keyboard 2. Then, the information center of Videotex is called up using the telephone 5, and as shown in step A2, TV program information for one month, for example, including TV program information including broadcasting station data, broadcasting time data, and program type data, is sent via the telesoft as shown in step A2. Receive information. In the videotex mode, the display switching circuit 15 is switched to the display memory 2G side, and the received videotex image stored in the display memory 26 is displayed on the CR7 display section 3. However,
When the videotex control device 25 receives television program information from the information center as a telesoft 1-, it stores the television program information in the program memory 16 in step A3. After that, the Deotex control device 25
A command is sent to the search circuit 17 to execute the initial process detailed in FIG. 6 in step A4, and the program information reception process is completed.

Next, details of the initial processing in step △4 will be explained with reference to FIG. The search circuit 11 first
As shown in step A11 in the figure, the designated address N of the program memory 16 is set to "1" (first address), and the contents of the designated address are read from the program memory 16 in step A2. Then, as shown in step A13, the date of the program read from the program memory 16 is compared with the current (today's) date clocked by the clock circuit 19, and if the current date is greater, that is, the broadcast date If it is before yesterday and has already finished broadcasting, the process proceeds to step A14 to set flag F2, and then proceeds to step A16. If the current date and the program date match, the process advances from step AI3 to step A15, where it is determined whether the current time measured by one clock circuit has passed the end time of the program. , if the current time has passed the end time of the program, the program proceeds to step A14 and sets the flag F2. However, if the current time has not passed the end time of the program, the process advances from step A15 to step A16. If it is determined in step AI3 that the current date is smaller than the date of the program, that is, the program has not been broadcast yet, the process directly proceeds to step A16. In this step A16, it is determined whether the specified address N of the program memory 16 has reached the final address. If it has not reached the final address, the specified address N is incremented by r+1J in step A, and then the process returns to step A12. Thereafter, the same process is repeated, program information is sequentially read out from the program memory 16, it is determined whether or not the broadcast of the program has ended, and a flag F2 is set for the program whose broadcast has ended. Then, when the specified address N of the program memory 1G reaches the final address, that state is detected in step A16, and the initial processing is ended. Here, the final address N may be fixed, but the initial processing may be ended when an end code is read from the program memory 16.

After storing the TV program information in the program memory 16 as described above and completing the initial processing, the keyboard 2
You can specify any type of program by key operation and have it search automatically.

When searching for a television program, the user operates the keys on the keyboard 2 to switch to the TV mode, as shown in step B1 in FIG. 7, and operates the program key.

When switched to TV mode, Videotex system mt
The device 25 constantly checks whether or not the program key is operated, as shown in step B2, and if the program key is not operated, the device 25 enters a state where it has input for other keys and returns to the normal TV reception state. The video signal output from the TV circuit 14 is displayed on the CR7 display section 3. However, when the program key is operated, the videotex control device 25 proceeds from step B2 to step B3 and displays the program menu on the CR7 display section 3-. In other words, as shown in Figure 8, "News", "Weather Forecast", "Baseball", "Sports", "Movies", "Culture", "Drama",
Program menus such as ``Uta'', ``Manga'', ``Quiz'', ``Wide'' (Wide number 1), and ``Conte J'' are displayed on the CR7 display section 3 along with corresponding numbers.

The user selects the CR7 display section 3 as shown in step B4.
The user specifies the corresponding number of the desired program from the program menu displayed on the keyboard 2 by operating keys on the keyboard 2. When the program designation number is input, the Videotex control device 25 outputs the designated program type code and search command to the search circuit 17 as shown in step B5, and then continues in the same state in step B6 until the search is completed. Hold. When the search operation of the search circuit 17 is completed and the designated station is selected, the Videotex control device 25 enters the state of waiting for other key human power and enters the normal TV reception state, and the search circuit 17 The program of the selected station is displayed as an image on the CRT display unit 3.

Next is the search time above! The detailed operations of g17 and flag control circuit 18 will be explained. In FIG. 1, the program memory 1G, the search circuit 17, the flag control circuit 18, and the clock circuit 19 are constantly supplied with an operating voltage regardless of whether the power is turned on or off. The clock circuit 19 constantly measures the current time and date, and supplies current time information and current date information to the search circuit 17 and the flag iJJ III circuit 18. Based on the time information from the clock circuit 19, the flag control circuit 18
Flag F1 of number vA information stored in program memory 16
, F2 are rewritten. FIG. 9 shows a flowchart of the m change processing of the flags Fl and F2, and the operation will be explained below according to this flowchart. The flag control circuit 18, as shown in step C1 in FIG. Read date data from. Then, the flag control circuit 18 generates a start address X and an end address XEND for the corresponding date area of the program memory 16 in accordance with the date data read from the clock circuit 19, as shown in step C3.

Then, the flag control circuit 18 sets the designated address N for the program memory 16 to the leading address X, as shown in step C4, and reads out the stored contents of the program memory 16 in step C5. Then, in step C6, it is determined whether the flag F2 is set. If the flag E2 is not set, the process proceeds to step C7, where it is determined whether the current time has passed the broadcast start time. If the current time exceeds the broadcast end time, the process proceeds to step c8, where it is determined whether the current time has reached the broadcast end time, and if the current time has not reached the broadcast end time, that is, the current If it is being broadcast, the flag F is set in step c9.
Set to 1. However, if the current time has reached the broadcast end time, the process advances from step C8 to step CIO;
The flag F2 is set and the flag F1 is reset. Then, when the process of step C9 or step C10 is finished, or when it is determined that the flag F2 is set (end of broadcast) in step C6, the current time reaches the broadcast start time in step C7. If it is determined that the specified memory address N has not reached the end address, the process proceeds to step C11, and it is determined whether or not the specified memory address N has reached the end address.If the specified memory address N has not reached the end address yet, the specified memory address N is
Go to "+1" and return to step C5. From here on, the same operation is repeated, and if the program is currently being broadcast, flag F1 is set, and if the program has finished broadcasting, flag F is set.
Set 2. When the processing for the date area of the current day in the program memory 16 is completed, the judgment result in step C11 becomes YES and the process returns to step C1, where the benefit is continued until the next one-minute pulse is sent from the clock circuit 19.

As described above, each time the clock circuit 19 outputs a 61-minute pulse, the flags Fl and F2 are switched.

As described above, the flags Fl and F2 in the program memory 16 are constantly being rewritten by the flag control circuit 18, but as described above, the type of program is designated by the key operation on the keyboard 2, and the step shown in FIG. At B5, when the type code and the search command are output from the videotex control device 25 to the search circuit 17, the search circuit 77 starts searching for a program. In other words, the above-mentioned Videotex system ii! The type code sent from the l device 25 to the search circuit 17 is set in the type code register 178, and the search command is input to the address generation circuit 177.

When the address generation circuit 171 receives the search command, it generates the start address x of the date area of the set of memories 16 in accordance with the date information from the clock circuit 19, and sets it in the address register 172.

The data set in the address register 172 specifies the start address X of the date area of the program memory 16, and information for one program at the specified address is read from the program memory 16 into the buffer 173. This buff? When the phase information is read out at 173, first, the flag F1 is sent to the flag discrimination circuit 176, and its contents are judged. If the program read into the buffer 173 is not being broadcast, the flag F1 is "0°", so in this case, the flag F1 is "+" from the flag discrimination circuit 176 via the OR circuit 177.
1'' signal is output, and the contents of the address register 172 are incremented by 14. This designates the next address in the program memory 16, and the program information stored at that address is read out to the buffer 173. The contents of the flag F1 are determined by the flag discriminating circuit 17G in the same manner as in the case of .If the flag F1 is "O", the same operation as described in F is repeated, but if the flag F1 is °1" ° ,
That is, if the program is being broadcast, a "1" signal is sent from the search circuit 17 to the type code comparison circuit 175. This type code comparison circuit 175 is connected to a flag discrimination circuit 176.
When a “1” signal is given from the buffer 173, the buffer 173
Type code and type code register 17 held in
8, and if they do not match, that is, if the program read into the buffer 173 is not the program specified by the keyboard 2, a mismatch signal is sent to the address register 172 via the OR circuit 177. Output. As a result, the contents of the address register 112 become “+
11, the next address in the program memory 16 is designated, and its contents are read into the buffer 173. This buffer 1
When new program information is set in 13, the flag F1 and type code are checked as described above. When the type code held in the buffer 173 and the type code held in the type code register 178 match, a match signal is sent from the type code comparison circuit 175 to the channel voltage generation circuit 174. That is,
If, for example, "News" is specified as the program type using the keyboard 2, a match signal is output from the type code comparison circuit 175 when the "News" program currently being broadcast is read from the program memory 16 to the buffer 173. and sent to the channel voltage generation circuit 174. When this channel voltage generation circuit 174 is given the type code match signal, it generates a voltage according to the channel code held in the buffer 173 and outputs it to the auto channel circuit 13. This auto channel circuit 13
When the channel voltage generation circuit 174 supplies the channel voltage, the receiver controls the receiving frequency of the tuner 12 in accordance with the channel voltage, and selects a station on the designated channel. When the type of program is specified using the keyboard 2 as described above, the channel on which the program is being broadcast is selected and displayed as an image on the CR7 display section 3. If no station is playing the specified type of program, such as "news," the station selected at that time will continue to be received. Furthermore, when two or more stations are playing the specified type of program at the same time, the station with the lowest order will be received.

Next, the program guide stored in the program memory 16 is displayed on the CR7 display section 3.
We will explain the operation when displaying on .

7, the program information stored in the work memory 27 is edited into an easy-to-read format. Thereafter, as shown in step H8, the edited program information is written from the work memory 21 to the display memory 26, and further from this display memory 26 to CR7.
It is sent to the display section 3 and displayed. That is, the program guide for the designated day of the week is displayed on the CR7 display section 3.

On the other hand, if it is determined in step H1 that the current day of the week and the specified day of the week are different, the process proceeds to step H9 to calculate the date of the nearest corresponding day, and step H10
Then, the start address X' corresponding to that date is generated as the designated address N of the program memory 16. After that,
Step l-1 performs the same process as steps H3 to H, etc.
11 to 814 are repeated. Then, in step 813, the designated address is the final address X'END.
If it is determined that the value has been reached, the process proceeds to step H7, where the editing process is performed, and the data is output to the display memory 2G and displayed on the CR7 display section 3, as shown in step H8.

Next, perform the key operation r of j during the broadcast in the above ■.
Regarding the operation when displaying the program guide currently being broadcast, Part 1
This will be explained with reference to Figure 6. The Videotex control device 25 is
When key operation I for the above ■ is performed on the keyboard 2, first, as shown in step 11 of FIG.
The start address X for the current date of the date area is generated as the designated address N of the program memory 16, and step I
2, the contents of the program memory 1G are read. Next, as shown in step I3, if the flag F1 is "1" or OI
! In other words, it is determined whether the program is being broadcast, and if the program is being broadcast, the program information is output to the work memory 27 as shown in step [4, and then the process proceeds to step I5. . If it is determined in step 13 that the program is not being broadcast, the process immediately proceeds to step I5 without performing the process in step I4. In step I5, it is determined whether the specified address N of the program memory 16 has reached the final address. If it has not reached the final address, the specified address N is updated in step 6, and the process returns to step I2. Thereafter, the same processing operation is repeated, and from among the program information stored in the program memory 16,
Only the program information currently being broadcast is selected and the work memory 27
written to. When it is determined in step I5 that the specified address in the program memory 16 has reached the final address in the current day's date area, the program proceeds to step I7 and the program information stored in the work memory 27 is edited in an easy-to-read format.

Thereafter, as shown in step I8, the edited program information is written from the work memory 27 to the display memory 26,
Further, the data is sent from this display memory 26 to the CR7 display unit 3 and displayed. In other words, a list of programs currently being broadcast is displayed on the CR7 display section 3.

In the above embodiment, if the program guide cannot be displayed on one screen, it may be scrolled or displayed for one day or one channel, and then moved to the next page by pressing a specific key such as the return key. do it.

Further, in the above embodiment, if the program information stored in the program memory 16 includes a large amount of performer information, it is possible to display a list of programs with specified performers.
