Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast receiving apparatus suitable for implementation as, for example, a teletext receiving apparatus.

[0002]

2. Description of the Related Art As is known as teletext, a broadcasting system has been implemented in which text data to be an independent program is superimposed and transmitted in a video signal of television broadcasting. In this teletext, one program is composed of character data for several pages, and the teletext receiving device extracts the text data from the received video signal of the television broadcast to extract the text for each page. A video signal to be a broadcast screen is generated and supplied to a monitor device for display.

In this teletext, the page transmission interval of the program, that is, the interval at which the receiving device can receive the information of each page is about 20 seconds. Therefore, if a program consists of, for example, 10 pages, it takes about 200 to receive the program.
This will take seconds. Therefore, when watching a teletext, if the user selects a program and then tries to receive and display the information of the selected program, the user has to wait considerably from the program selection operation to the actual display output. It will often be done.

For this reason, in the conventional teletext receivers,
A function called reservation registration is provided. This is because when a user selects a program to watch in advance and makes a reservation registration, the receiving device stores the program content in a memory in response to the reception of the program. When the user selects the program for actual viewing, the content of the program is read from the memory so that it can be immediately displayed on the monitor.

For example, a case where the program is a weather forecast will be taken as an example. It is assumed that the content of this program is updated three times a day in the morning, noon, and evening, and that it is composed of about 10 pages. If the user reserves and registers this weather forecast program, the receiving device stores the program contents for 10 pages in the memory every time the weather forecast program that is repeatedly broadcast is received. As a result, even if the content is updated, the latest program content is always held in the memory as the weather forecast. Then, when the user selects a weather forecast program for viewing, the program content held in the memory is immediately displayed. For example, even if the user wants to see the contents of the fifth page, it can be displayed immediately by pulling it out from the memory.

[0006]

By the way, a character broadcast is a program that is repeatedly broadcast while information is updated at a predetermined time. For example, as for road traffic information, the latest information is repeatedly transmitted from about 10 minutes and 40 minutes every hour, for example, information updated at 0 minutes and 30 minutes every hour in a predetermined time zone of the day. Therefore, when the broadcast program of the road traffic information is reserved and registered, the program contents received around 10 and 40 minutes every hour are stored as the contents just updated. However, for example, when programs such as other weather forecasts and stock information are also reserved, the latest contents cannot always be stored as a program of road traffic information in order to receive these programs. In other words, looking at one program when multiple programs are reserved and registered, it is not always possible to receive that program, so it is possible that the user can always obtain the latest information from the text broadcast. There is a problem that it is not limited.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and includes receiving means for receiving a broadcast, storage means for storing the content of the received broadcast program, and predetermined broadcast. Based on the reception time information stored in the priority reservation storage means, the priority reservation storage means capable of storing the specification information of the program and its periodic reception time information, and the broadcast program indicated by the corresponding specification information. The broadcast receiving apparatus is configured to include control means capable of receiving and controlling to store in the storage means.

According to the present invention, it is possible to set a channel, a channel number, and periodical reception time information which is a timing immediately after updating as a priority reserved program for a certain program. Therefore, by always registering a broadcast program in which the user desires the latest contents as a priority reserved program, the latest information can be surely obtained for the program.

BEST MODE FOR CARRYING OUT THE INVENTION A teletext receiving apparatus as an embodiment of the present invention will be described below. FIG. 1 is a block diagram of a teletext receiver. The television broadcast radio wave received by the antenna 1 is selected by the television tuner 2, demodulated, and a video signal broadcast on that channel is output.

The video signal output from the television tuner 2 is supplied to the T terminal of the switch 3. The output of the switch 3 is supplied from the terminal 4 to the monitor device. Therefore, when the switch 3 is connected to the T terminal, the monitor apparatus is supplied with a video signal as a normal television broadcast, and the television broadcast is displayed. There are various conceivable modes of connection between the teletext receiver and the monitor device (for example, a television receiver). For example, the video signal may be connected in the RF signal form, or the composite video signal form or the Y / C video signal form. Further, the RGB signal form is also conceivable. The configuration of the output circuit system in the preceding stage of the terminal 4 is different due to the difference in these signal forms, but this point will not be described in detail. It is also conceivable that the teletext receiver is built in a television receiver.

The code extraction unit 5 extracts data as a character broadcast superimposed on a predetermined line in the vertical blanking period in the received / demodulated video signal. The extracted data is once supplied to the controller 6. The controller 6 is composed of a microcomputer as a control unit. Then, the operation of each part is controlled by the control signal SG.

The controller 6 can directly supply the extracted teletext data to the screen synthesizing section 8 to synthesize a video signal as a teletext program. Further, the controller 6 temporarily stores the extracted teletext data in the program memory 7
It is also possible to store it in a, read it out when the user views it, and supply it to the screen synthesizing unit 8 to synthesize a video signal as a teletext program. The output of the screen synthesis section 8 is supplied to the M terminal of the switch 3. When viewing the teletext, the controller 6 connects the switch 3 to the M terminal, whereby the monitor apparatus outputs the video as the teletext synthesized by the screen synthesis unit 8.

The operation unit 9 is provided with an operation key for the user to select a teletext program and an operation key for making a reservation registration. For example, the front panel of this teletext receiver is formed as shown in FIG. 4, and the ten keys 21 and "#" keys "0" to "9" for selecting the program number, the reservation mode key 23, and the reservation set are set. A key 24, a channel up / down key 25, etc. are provided. Further, in the present invention, a priority reservation key 26 for storing the designated program with priority is provided.
By using the ten-key pad 21, the “#” key 22, etc., to register the program and the cyclic time as a reservation, which will be described later, it is possible to always hold the latest contents of the program as a priority reservation. be able to. Although not shown, a remote commander for the teletext receiver is prepared, and operations such as channel and program number selection can be performed using the remote commander.

Regarding program selection, the user operates a channel up / down key 25 or the like to select a certain broadcasting station channel, and further selects a program number. To select the program number, for example, the ten keys 21 of "0" to "9" and the "#" key 22 are used. For example, if the user operates "1""2""3""#", the program number "1"
23 # ”has been designated.

The user can also perform an operation for reservation registration from the operation unit 9. For example, if the user operates the reservation mode key 23, then operates the channel "1", the program numbers "1""5""6""#", and further operates the reservation set key 24, the controller 6
Recognizing that the program with the program number “156 #” on channel 1 has undergone the reservation registration operation, the channel 1 / program number 1
The data "56 #" is stored in the reservation registration memory 7b as reservation registration data.

To make a priority reservation, the priority reservation key 26 is first operated, and then, for example, the channel "1" and the program numbers "1""5""6""#" are operated as described above. Further, if the hourly reception time of the reserved program is, for example, "10" minutes and "40" minutes, for example, the time immediately after that, such as "12" minutes and "42" minutes, is input with the ten keys. The user may input the reception time by referring to the program guide or the like. As a result, data indicating that the program of "channel 1 / program number 156 #" is stored, for example, for "12" minutes and "42" minutes per hour is stored in the priority reservation registration memory 7c as priority reservation data. Note that, for example, setting the priority reservation registration time to "12" minutes and "42" minutes per hour, which is slightly later than the reception time, is for some reason not to receive and store the data before update. Is. In other words, this is for surely receiving the broadcast program that has been registered for priority reservation.

The reservation registration memory 7b stores normal reservation registration data set according to a user's operation. For example, channels and program numbers of various programs are stored as reservation registration data as shown in FIG. Then, for the program registered in the reservation registration memory 7b, the controller 6 stores the program content extracted by the code extraction unit 5 in the program memory 7a every time the program is received.

The priority reservation registration memory 7c stores registration data of priority reservations registered by the priority reservation key 26. Then, for example, as shown in FIG. 5, the program channel, the program number, and the reserved reception time (periodic reception time information) as the priority program every hour are stored. The reception reservation time of the priority program is, for example, “Channel 4
/ Program number 42 # ”, once every 18 minutes, or like“ Channel 8 / Program number 125 # ”, every 5 minutes, 25 minutes, 45 minutes It may be three times, for example, it may be adapted to a program that is frequently updated.

In any case, if the data is only "minutes", it will be a periodic reception time every hour, and if the data is "hours and minutes", it will be a periodic reception time every day. Although the reservation registration memory 7b and the priority reservation registration memory 7c are shown separately for the sake of explanation, it is only necessary that the reservation registration memory 7b and the priority reservation registration memory 7c are set by dividing the area in the same memory unit. In this case, the normal reserved program and the priority reserved program may be identified by providing an identification flag or the like.

The storage capacity of the program memory 7a is set so that a relatively large amount of teletext contents, such as 300 pages, can be stored. Then, by holding the program registered for reservation and the program registered for priority reservation in the program memory 7a, when the user wants to watch the program and performs the operation of designating the channel and the program number as described above. The controller 6 can immediately read the content of the program from the program memory 7a and output the video of the program on the monitor device. For example, in the program memory 7a, the contents of the program are stored together with the channel number and the program number in response to the reception of a certain reserved and registered program as shown in FIG. The amount of data as the content of the program depends on how many pages of the program the image is composed of, and has a different data size for each program.

The clock unit 10 counts, for example, year, month, day, hour, minute and second as current date and time information, and is configured to be able to supply the current date and time information to the controller 6. The controller 6 detects the time information from the clock unit 10 and performs control such that the priority reserved program is stored when the priority reservation time set in the priority reservation registration memory 7c has come.

When the user performs an operation of designating a program that is not registered for reservation, the controller 6 causes the television tuner 2 to receive the channel, and causes the code extraction unit 5 to receive the channel according to the program number. The operation of extracting character data as the program is executed. Then, the screen synthesizing unit 8 is caused to generate a screen as a broadcast program from the extracted character data and is displayed on the monitor device.

The operation relating to the reception modes of the reservation registration and the priority reservation registration realized in such a teletext receiver will be described below. FIG. 6 is a diagram schematically showing the reception status of reservation registration and priority reservation registration. here,
For example, as shown in FIG. 5, "channel 1 / program number 001
This shows the case where priority reservation registration is performed so that “#” is received prior to “12” minutes and “42” minutes every hour, and other programs are also normally reserved, and time elapses in the vertical axis direction. Is shown.

For example, if the reservation time of another program that is normally reserved and registered is about 14:00 and the information amount of the program is large, it takes a considerable time to store the information. In this case, "Channel 1 / Program number 0
There was a case that it could not be stored because it overlapped with the update time of the program of "01 #", but by registering priority reservation, if the priority reservation time is reached even while recording a program, for example, another program. Priority reserved programs are received and stored with priority.

That is, as shown in FIG. 6, when another program is being received, every time the hour, for example, "12" or "42" set as the priority reservation arrives, another program is received. The reception of the program is temporarily stopped, and the reception is switched to the reception of the priority reserved program. Then, when the reception and storage of the priority reserved program are completed, the operation is switched again to the reception and storage operation of another normal priority reserved program. By repeating such a receiving operation every hour, the program for which priority reservation registration is performed can be surely received immediately after being updated, so that the user can always see the latest information. Further, the method of priority reservation registration is simple because it is sufficient to input numbers such as "12" and "42" in minute units in addition to setting channels and programs.

Next, a learning function for automatically setting the reception time of the priority reserved program will be described. In the case of teletext,
A flag called an update flag is set in the header of the data of the program content to be transmitted, and this is determined as data for inverting "1" and "0" when the broadcast station side updates the program content. . By detecting the interval at which the update flag is inverted, it is possible to set a cycle for updating the program content and rewrite the program content stored in the memory.

First, the flow of processing for detecting the update period of the teletext according to the flowchart shown in FIG. 7 will be described. When the priority reservation program is reserved and registered by operating the priority reservation key 26 or the like as described above (S001), the reception standby state is set in this state, and it is determined whether or not the priority reserved program is received until it is received. (S002). When the priority reserved program is received, the program contents are stored in the program memory 7a, and the reception time and the update flag are stored in the priority reserved memory 7c (S003). Then, it is determined whether or not the update flag is the same as the one stored last time (S004), but since the update flag is not yet stored for the first time, the process directly returns to step S002 and waits for reception. Then, the process proceeds to S004 again in a predetermined cycle.

If the update flag has been updated, the update cycle of the broadcast program for which priority reservation registration has been performed is calculated from the current time and the previously received time (S005). Then, the update cycle calculated here is stored in the priority reservation registration memory 7c as the reception cycle of the priority reservation program.

The outline of the flow chart shown in FIG. 7 will be described with reference to the list of reception times and update flags shown in FIG. It is assumed that the reception time in step S003 is "1:00", for example. And the update flag is not yet stored for the first time, so step S003 remains as it is.
Return to If the detection interval at this time is, for example, every 10 minutes as shown in FIG. 8, the process proceeds to step S004 again at "1:10". Since the update flag is "1" even at the time of "1:10", further step S0
After going from 02 to S004 and proceeding to step S004 at "1:20",
Since the update flag is updated to "0" here,
It is assumed that the program content has been updated when 20 minutes have passed since "1:00".

Further, for example, "1:20" to "2: 0".
For "0", by detecting the update flag in the same manner, it is possible to determine that the program has been updated when 20 minutes have elapsed. Then, it becomes possible to judge that the update has been performed three times in one hour of “1:00”, “1:20”, and “1:40” from the first reception time. By detecting the update cycle of the update flag in this manner, it is possible to detect how many minutes each hour the priority reserved program is updated. Therefore, when the controller 6 performs such an operation and detects the periodic time information, the controller 6 stores it in the priority reservation registration memory 7c so that the user can input the periodic reception time information at the time of the priority reservation. It is not necessary to do it and the operation can be simplified.

[0031]

As described above, the broadcast receiving apparatus of the present invention can register a program particularly desired by the user as a priority reserved program with a reserved time specified, and the program can be registered at a predetermined time every hour, for example. When it comes to, it is possible to receive and store it with priority. As a result, even when a plurality of programs are reserved and registered, the latest information can be surely stored for the priority program, and the user can always watch the latest broadcast content. Further, with respect to the priority program, periodic reception time information is set, and reservation can be made by a simple operation such as inputting in minutes. Further, by determining the update time and automatically setting the periodical reception time information, the reservation operation by the user is further simplified.
