Description

  The present invention relates to a time management system for data broadcasting, and in particular, a set time set by a user or information set by a user using TOT (Time Offset Table) and TDT (Time Date Table) provided in digital broadcasting. The present invention relates to a technique for displaying a remaining time up to a time derived from the information on a receiver or displaying information desired by a user.

  In recent years, terrestrial digital broadcasting has started, and a system called a transport stream is used for this broadcast wave, and a broadcast wave in which program (program) data is multiplexed is transmitted by a plurality of transport streams. The The broadcast wave includes various data in addition to program data, and includes a data group having a PID (packet Identefier) called TOT. This TOT includes data such as JST (Japan Standard Time) time, date (hereinafter collectively referred to as current time), and time offset value when daylight saving time is introduced.

  FIG. 14 is an overall configuration diagram of a conventional digital broadcast receiver 100. In FIG. 14, 100 is a digital broadcast receiver, 200 is a receiving unit that receives and separates broadcast waves, 300 is a time management unit that performs time management of the digital broadcast receiver, 400 is an internal clock provided in the receiver 100, Reference numeral 500 denotes a broadcasting station that transmits a broadcast wave.

  The digital broadcast receiver 100 has a function of extracting a TOT included in a broadcast wave and setting or correcting (hereinafter referred to as adjustment) the current time in the internal clock 400. The operation of this time adjustment function will be described below.

  When the power of the digital broadcast receiver 100 is turned on, the receiving unit 200 starts processing the received broadcast wave. The receiving unit 200 separates each program program data and other data into each data based on the multiplexed data included in the broadcast wave. The receiving unit 200 processes the separated data and transmits a signal including the TOT to the time management unit 300.

  The time management unit 300 processes a signal including TOT data received from the reception unit 200 and extracts each data included in the TOT. Further, among the data, for the current time data, a signal including the current time data is transmitted to the internal clock 400. The internal clock 400 adjusts the current time used for screen display, reservation, and the like based on a signal including current time data.

  The time management unit 300 stores and manages data included in the TOT other than the current time data. Here, when daylight saving time is introduced, a time offset value is also set in the TOT. In this case, the time management unit 300 also sets and cancels daylight saving time for the internal clock 400 based on the value.

  In this way, time is accurately controlled in digital broadcasting.

  In addition, a technique for providing a timer function in a television receiver and displaying the remaining time up to a predetermined time on a screen has been disclosed (for example, Patent Document 1).

Typical time information used for data broadcasting includes TOT (Time Offset Table) and TDT (Time Date Table). In the present invention, TOT (Time Offset Table) is used.
Table) or TDT (Time Date Table), or both.

  Specific examples will be described below.

  A first embodiment of the present invention will be described.

  FIG. 1 is a diagram illustrating a configuration of a time management system using data broadcasting according to the first embodiment. As shown in FIG. 1, this time management system includes a broadcasting station 1 that broadcasts data broadcasting and a receiver 2.

  The broadcast station 1 includes a storage unit 11 in which a control program necessary for time management is stored, a data broadcast unit 12 that transmits the control program and other data broadcast data, and data transmitted from the data broadcast unit 12. And a multiplexing unit 13 that multiplexes and broadcasts the main line side program / audio and TOT (Time Offset Table) that is time information.

TOT (Time
Instead of (Offset Table), TDT (Time Date Table) may be used, or both may be used.

  The control program necessary for time management stored in the storage unit 11 includes a data input program for inputting data necessary for time management on the receiver 2 side, data relating to the input time limit, and the current time. And a time management / display program for managing time.

  The data input program is a program that activates a data input screen on the receiver screen and stores the input data (date and time) in an NVRAM operator-exclusive area described later. The time management and display program calculates the remaining date and time by comparing the data (date and time) stored in the NVRAM operator-dedicated area with the time information TOT (Time Offset Table), and displays the receiver screen. This is the program to be displayed above. These data input program and time management / display program will be described later.

  The receiver 2 receives the digital broadcast, and separates and transmits the main line side video / audio, data broadcast, and other data, personal data and special information of the business operator. A first storage unit (NVRAM) 22 to be stored, a second storage unit 23 to store programs and the like, a time management / display unit 24 for managing and displaying time based on a control program, time and the like Is displayed, an input control unit 26 for controlling data input, and an input unit 27 for inputting data.

  The digital broadcast receiving unit 21 stores the data input program and the time management / display program in the storage unit 23 and transmits a TOT (Time Offset Table) to the time management / display unit 24.

  As shown in FIG. 2, the storage unit (NVRAM) 22 has a common area 221 and an operator-exclusive area 222. These areas are basically stored even if the channel is changed. This area is not erased.

  On the other hand, the storage unit 23 is a storage unit in which data and programs stored so far are deleted when a channel is changed. The data input program and the time management / display program received by the digital broadcast receiving unit 21 are stored in the storage unit 23, and basic data (date and time, etc.) input by the user described later is stored in the storage unit (NVRAM) 22 business. Stored in the person-only area 222.

  In this embodiment, the storage unit (NVRAM) 22 does not erase the stored data even if the channel is changed. However, a part of the storage unit (NVRAM) 22 is changed by the channel change. When the stored data and programs are erased, the data input program and the time management / display program may be stored in the area. Further, instead of NVRAM, a register such as a Greg that holds contents until the power is turned off may be used.

  The input control unit 26 displays an input screen based on the data input program stored in the storage unit 23, and the data input by the user through the input unit 24 is stored in the operator dedicated area 222 of the storage unit (NVRAM) 22. To store.

  The time management / display unit 24 is based on the time management / display program stored in the storage unit 23, and the time limit information of the user (viewer) stored in the operator exclusive area 222 of the storage unit (NVRAM) 22 The difference between (year, month, date and time) and the current time indicated by TOT (Time Offset Table) is calculated, and the remaining time until the user's deadline is calculated. Then, the remaining time is displayed on the display unit 25.

  An example of a control program for operating the time management / display unit 24 and the input control unit 26 is shown in FIGS.

  In the illustrated program, first, “function RemainTime ()”, which is a function for calculating and displaying the remaining time from the registration time recorded in the NVRAM and the current time, is defined. These processes are processes for reading registration time data from NVRAM, subtracting the current time from the registration time, and determining the display color of the remaining time.

  Furthermore, “if (remain_time <= a)”, which is a function for displaying the calculated remaining time (time), is defined a minute before the registration time.

  Also, a function “if (remain_time ≦ b)” is defined that changes the displayed character color of the remaining time to red when the remaining time is less than b minutes.

  In addition, when the remaining time is 0, for example, when the departure time is reached, the function “if (remain_time == 0)” is defined to change the background color to yellow, change the display to departure, and sound a warning sound. Has been.

  Further, “if (remain_time> = − 1 * c)” is defined, which is a function for displaying XX minutes over until the remaining time, for example, c minutes beyond the departure time.

  In addition, if the remaining time is greater than a minute and more than c minutes, “if (remain_time> a || remain_time <-1 * c)” is defined, which is a function to turn off the display of the remaining time. .

  The above is the time management / display program.

  On the other hand, in the data input program, “function memory ()”, which is a function for registering time in NVRAM described later, is defined.

  The time management / display unit 24 and the input control unit 26 operate according to such a control program.

  The input unit 27 is, for example, a remote controller or a button provided on the receiver.

  Next, the operation in the above configuration will be described.

  FIG. 5 is a flowchart showing the operation of the first embodiment.

  First, a viewer selects a data broadcast of a broadcasting station implementing the present invention (Step 100), and receives a control program by the digital broadcast receiving unit 21 (Step 101). And this control program is stored in the memory | storage part 23 (Step 102).

  Subsequently, the time management / display unit 24 that operates according to the time management / display program stored in the storage unit 23 stores data such as a name and a time limit (time) in the operator-specific area 222 of the storage unit (NVRAM) 22. It is determined whether it is stored (Step 103, Step 104).

  If there is no data, the input control unit 26 starts the data input process and displays the data input screen based on the data input program in the storage unit 23 in order to input data related to the viewer's time limit. (Step 105).

  The viewer inputs a name and a time limit (time) according to the input screen (Step 106). And the input control part 26 stores data, such as a name and time limit (time), in the provider exclusive area | region 222 of the memory | storage part (NVRAM) 22 based on a data input program (Step 107).

  Here, an example of data input will be described with reference to an input screen.

  When data input is selected, the input control unit 26 displays a data input screen as shown in FIG. Here, an example of an input screen that can input up to three deadlines is shown.

  Next, when the input 1 is selected, a name for identifying who the input 1 is for is selected. In FIG. 7, dad is selected from dad, mom, and me.

  Finally, by inputting and determining the registration time (time limit), the name and the time limit (time) are stored in the operator exclusive area 222 of the storage unit (NVRAM) 22. This display screen is shown in FIG.

  Next, the time management / display unit 24 that operates according to the time management / display program acquires the current time indicated by the TOT (Time Offset Table) (Step 108), and stores this current time in the operator exclusive area 222. The difference between the set deadline (time) and the current time indicated by the TOT (Time Offset Table) is calculated, and the remaining time until the deadline of the viewer is calculated (Step 109). And this remaining time is displayed on the display part 25 with a name (Step 110). An example of this is shown in FIG. Note that processing is performed as in the above-described program when the display color is changed according to the remaining time, a warning is issued, or the remaining time becomes negative.

  This is continued while watching the channel providing the service. On the other hand, when the channel is changed, the control program stored in the storage unit 23 is deleted, so that the time management by the time management / display unit 24 is stopped and the remaining time is not displayed (Step 111).

  This configuration provides viewers with a convenient service for displaying the remaining time, and changing the channel stops the calculation of the remaining time and prevents it from being displayed. Can also be planned.

  In the case of stream accumulation / reproduction, the time indicated by the digital receiver built-in clock that holds the absolute time calibrated by TOT or the like is compared and subtracted from each set deadline time.

  Further, as a modification example described above, in order to display the remaining time on the television program in a superimpose format, it is possible to transmit a data broadcast in which information other than the remaining time information is made transparent. An example of this display screen is shown in FIG.

  A second embodiment will be described.

  In the second embodiment, the function is changed to a function for setting a specific date such as a birthday instead of the deadline time. In this way, it becomes a countdown meter that displays how many days (or hours, minutes, or seconds) remain until that day. As an application that uses this function, in addition to counting down to a specific date, if you set the collection date of garbage and display only the current day, it will be a service that notifies you of the garbage day.

  A third embodiment will be described.

  In the third embodiment, the function is changed to a function for setting the required time instead of the deadline time. In this way, it becomes a timer service. In this case, the viewer is requested to take a timer start action on the data broadcast. When a start action (such as pressing a button) is received, a time obtained by adding the time set to the current time is set as a comparison time. Then, the time and the current time are subtracted and compared, and the result is displayed.

  FIG. 11 shows an operation flowchart in such a configuration.

  First, the time management / display unit 24 that operates according to the time management / display program acquires the current time indicated by the TOT (Time Offset Table) at the time of a start action (such as pressing a button) (Step 200) (Step 201). Then, the set required time (for example, one hour) is added to the current time (Step 202), and this is stored in the operator exclusive area 222 as the timer time (Step 203).

  Then, the current time indicated by TOT (Time Offset Table) is subtracted from the timer time (Step 204), and the result is displayed (Step 205).

  To use it, register the required time from the company or school to your home, and press the timer start button on the data broadcast when you return home. That way, while watching TV, you ’ll see an indication of how many minutes you ’ll be returning on that screen.

  Example 4 will be described.

  In Example 4, for example, timetable data of transportation such as trains, airplanes, and buses is taken into a receiver from a broadcasting station or an external server, and based on the timetable data, the remaining time until the departure, etc. An example of displaying is described. In the following description, a train timetable will be described as an example of timetable data.

  Example 6 will be described.

  Embodiment 6 is a time management system that obtains traffic route information from a departure place to an arrival place of a predetermined transportation facility from an external server, and displays the remaining time until the departure time of the departure place. In the sixth embodiment, a train is taken as an example of the transportation system, the traffic route from the departure station to the arrival station desired by the viewer is searched, and the remaining time until the departure time of the departure station is managed. An example of display will be described.

  FIG. 18 is a diagram illustrating a configuration of a time management display system using data broadcasting according to the sixth embodiment. As shown in FIG. 18, the time management display system includes a broadcasting station 600 that broadcasts data broadcasting, a receiver 700, and a server 800.

  The broadcast station 600 is transmitted from a storage unit 601 in which a control program necessary for time management and display is stored, a data broadcast unit 602 that transmits the control program and other data broadcast data, and a data broadcast unit 602. And a multiplexing unit 603 that multiplexes and broadcasts the main line side program / audio and TOT (Time Offset Table) that is time information. In place of TOT (Time Offset Table), TDT (Time Date Table) may be used, or both may be used.

  A control program necessary for time management / display stored in the storage unit 601 is a data input for inputting data necessary for searching a traffic route such as a departure station, an arrival station, and an arrival time on the receiver 700 side. The program includes a time management / display program that obtains a traffic route based on the input information, and compares the departure time with the current time to manage the time.

  The data input program is a program that activates the data input screen on the receiver screen and stores the input departure station, arrival station, arrival time, and the like in the NVRAM operator-dedicated area.

  The time management / display program transmits data (departure station, arrival station, arrival time, etc.) stored in the NVRAM operator-dedicated area to the server 800 to obtain information on the traffic route, and displays this traffic route. At the same time, it is a program that calculates the remaining time by comparing the departure time and TOT (Time Offset Table), which is time information, and displays it on the screen of the receiver. These data input program and time management / display program will be described later.

  The receiver 700 receives a digital broadcast, separates and transmits the main line side video / audio, data broadcast, and other data, and receives personal data and special information of the operator. A first storage unit (NVRAM) 702 to be stored, a second storage unit 703 to store a program and the like, a time management / display unit 704 for managing and displaying time based on a control program, a time and the like Is displayed, an input control unit 706 that controls data input, an input unit 707 for inputting data, and a transmission / reception unit 708 that transmits / receives data to / from the server 800.

  The digital broadcast receiving unit 701 stores a data input program and a time management / display program in the storage unit 703 and transmits a TOT (Time Offset Table) to the time management / display unit 704.

  As shown in FIG. 2 described above, the storage unit (NVRAM) 702 includes a common area 221 and a provider-exclusive area 222. These areas are basically stored even if the channel is changed. Data is an area that is not erased.

  On the other hand, the storage unit 703 is a storage unit in which data and programs stored so far are deleted when a channel is changed. The data input program and time management / display program received by the digital broadcast receiving unit 701 are stored in the storage unit 703, and basic data (departure station, arrival station, arrival time, etc.) input by the user is stored in the storage unit ( (NVRAM) 702 is stored in the operator exclusive area 222.

  In this embodiment, the storage unit (NVRAM) 702 does not erase the stored data even if the channel is changed. However, a part of the storage unit (NVRAM) 702 is changed by the channel change. When the stored data or program is erased, the data input program and the time management / display program may be stored in the area. Further, instead of NVRAM, a register such as a Greg that holds contents until the power is turned off may be used.

  The input control unit 706 displays an input screen based on the data input program stored in the storage unit 703, and the data input by the input unit 704 operated by the user is dedicated to the operator of the storage unit (NVRAM) 702. This is stored in the area 222.

  The time management / display unit 704 is based on the time management / display program stored in the storage unit 703 and information on viewers (departure station, NVRAM) 702 stored in the operator-dedicated area 222. By obtaining information on the traffic route from the server 800 according to the arrival station and arrival time, etc., displaying this traffic route, and comparing the departure time and time information with the TOT (Time Offset Table), the remaining time is obtained. calculate. Then, this remaining time is displayed on the display unit 705.

  Further, when there are a plurality of ranks in the traffic route obtained from the server 800, the rank of the traffic route selected by the viewer is stored in the operator exclusive area 222 of the storage unit (NVRAM) 702. Originally, if the storage unit (NVRAM) 702 has a large storage capacity, it is preferable to store all received data in the storage unit (NVRAM) 702. However, the capacity of the operator exclusive area 222 of the storage unit (NVRAM) 702 is very small, for example, only about 64 × 64 bytes, and it is impossible to store all received data.

  Therefore, in the operator exclusive area 222 of the storage unit (NVRAM) 702, information of the viewer (departure station, arrival station, arrival time, etc.) and the order of the traffic route selected by the viewer are stored to change the channel, etc. Thus, even if the time management / display program stored in the storage unit 703 or the obtained traffic route information is erased, the time management / display program is restored to the original channel again. When the operation is started after being stored in 703, the traffic route is re-established based on the viewer information (departure station, arrival station, arrival time, etc.) stored in the operator exclusive area 222 of the storage unit (NVRAM) 702. If the information is obtained and the information on the traffic route corresponding to the order stored in the operator exclusive area 222 of the storage unit (NVRAM) 702 is selected, the traffic route selected by the viewer is selected. It is possible.

  This is because if the information such as the departure station, arrival station, and arrival time is the same, the server 800 transmits a plurality of traffic routes with the same ranking as previously transmitted.

  The input unit 707 is, for example, a remote controller or a button provided on the receiver.

  Next, the operation in the above configuration will be described.

  FIG. 19 is a flowchart showing the operation of the sixth embodiment.

  First, the viewer selects a data broadcast of a broadcasting station implementing the present invention (Step 500), and receives a control program by the digital broadcast receiving unit 701 (Step 501). The control program is stored in the storage unit 703 (Step 502).

  Subsequently, the time management / display unit 704 that operates according to the time management / display program stored in the storage unit 703 stores the viewer's data (departure station, arrival station) in the business operator exclusive area 222 of the storage unit (NVRAM) 702. And arrival time etc.) are stored (Step 503, Step 504).

  If there is no data, the input control unit 706 starts data input processing based on the data input program in the storage unit 703 in order to input viewer data (departure station, arrival station, arrival time, etc.). Then, the data input screen is displayed on the display unit 705 (Step 505).

  The viewer inputs viewer data (departure station, arrival station, arrival time, etc.) according to the input screen (Step 506). Based on the data input program, the input control unit 706 stores viewer data (departure station, arrival station, arrival time, etc.) in the operator-specific area 222 of the storage unit (NVRAM) 702 (Step 507). ).

  Here, an example of data input will be described with reference to an input screen. FIG. 20 is a diagram showing an example of the data input screen.

  When the data input is selected, the input control unit 706 displays a data input screen as shown in FIG. 20 on the display unit 705. Here, an example of a screen for inputting a boarding station (departure station), a stop station (arrival station), and a desired arrival time is shown. Furthermore, it is also possible to input the required time from the viewer's departure place, for example, home to the boarding station. By inputting this required time, the remaining time until the departure time is calculated in consideration of the required time from the home to the boarding station.

  Finally, by inputting data and selecting search, the boarding station (departure station), the getting-off station (arrival station) and the desired arrival time, if entered, the required time from home to the boarding station (NVRAM) 702 is stored in the operator exclusive area 222.

  Next, the time management / display unit 24 that operates according to the time management / display program includes the boarding station (departure station), the getting-off station (arrival station), and the station (departure station) stored in the operator-specific area 222 of the storage unit (NVRAM) 702. Data of the desired arrival time is transmitted to the server 800 via the transmission / reception unit 708 (Step 508).

  In the server 800, a traffic route corresponding to the received boarding station (departure station), getting-off station (arrival station) and desired arrival time data is searched (Step 509), and the corresponding traffic route is transmitted to the receiver 700. (Step 510). In many cases, there are a plurality of traffic routes. In this case, the traffic routes are ranked and transmitted. Further, it is assumed that the departure time of the departure station and the arrival time of the arrival station are included in the traffic route. These techniques are the same as those used for searching for traffic routes performed on the Internet or the like.

In the receiver 700, the traffic route information is received by the transmission / reception unit 708 (Step 511), and the traffic route information is stored in the storage unit 703 (Step 512).
Subsequently, the time management / display unit 24 that operates in accordance with the time management / display program determines whether the storage unit (NVRAM) 702 stores data related to the order of the traffic route selected by the viewer from a plurality of traffic routes. (Step 513).

  When the data related to the order of the traffic route is not stored (stored) in the storage unit (NVRAM) 702, the time management / display unit 24 displays the information on the traffic route stored in the storage unit 703 based on the information on the traffic route. A traffic route is displayed in 705 with ranking (Step 514).

  FIG. 21 is an example of a display of traffic routes from route 1 to route 10. However, the viewer can see the route 1. Thus, the traffic routes ranked in the server 800 are displayed as they are.

  Next, the viewer selects a desired traffic route from a plurality of traffic routes (Step 515), and the time management / display unit 24 stores the order of the selected traffic route in the storage unit (NVRAM) 702. The information is stored in the provider exclusive area 222 (Step 516).

Then, the traffic route selected by the viewer is displayed (Step 517). In Step 513, when the data regarding the order of the traffic route is stored (stored) in the storage unit (NVRAM) 702, the information of the traffic route having the order corresponding to the information of the order is received and stored. The traffic route is selected from a plurality of traffic routes stored in the unit 703, and this traffic route is displayed (Step 517).
Next, the time management / display unit 704 that operates according to the time management / display program acquires the current time indicated by the TOT (Time Offset Table) (Step 518), and stores the current time and the storage unit (NVRAM) 702. The difference with the departure time of the traffic route specified by the rank of the traffic route stored in the operator exclusive area 222 is calculated, and the remaining time until the departure time of the viewer is calculated (Step 519). At this time, if the required time from the home to the boarding station is input, this required time is further subtracted from the remaining time, and this time is taken as the remaining time. Then, the remaining time is displayed on the display unit 705 (Step 520). An example of this is shown in FIG. The display color can be changed or a warning can be issued depending on the remaining time. When the remaining time becomes negative, the display may not be displayed after a predetermined time has elapsed, or the same processing as in the first embodiment may be performed.

Then, the processing from Step 518 to Step 520 is continued while viewing the channel providing the service. On the other hand, when the channel is changed (Step 521), the control program stored in the storage unit 703 is deleted, so that the time management by the time management / display unit 704 is stopped and the remaining time is not displayed.
In addition to the channel change, if the same channel is changed to another service, for example, if this service is changed to the data broadcasting weather or news of the same channel, the screen display changes. Since the program is not erased from the storage unit 703, when returning to the service again, the processing from Step 503 is started.

  This configuration provides viewers with a convenient service for displaying the remaining time, and changing the channel stops the calculation of the remaining time and prevents it from being displayed. Can also be planned.

  Even if the channel is changed once, the control program is stored in the storage unit 703 again by selecting the channel to the broadcasting station that provides the service, and the time management / display unit 704 operates to store the channel. Based on the information stored in the unit (NVRAM) 702, traffic route information is obtained again from the server 800. Then, the traffic route selected by the viewer is selected by selecting the traffic route information of the corresponding order from the obtained information of the plurality of traffic routes according to the order of the stored traffic route (the order selected by the viewer). The remaining time until the departure time can be calculated and displayed.
