Description

  The present invention relates to a digital broadcast receiving apparatus and a digital broadcast receiving method for selecting and receiving a digital broadcast program by inputting a three-digit number.

Conventionally, as a channel selection method in a digital broadcast receiver, there are up / down channel selection for selecting a service before and after a viewing service, and one-touch button channel selection for selecting a service assigned in advance to a remote control button. As a method for selecting one unspecified service from such a large number of services, there has been a three-digit number input channel selection in which a three-digit number of a service is input to select a channel. In this apparatus, when inputting a three-digit number, a channel selection target is presented to the user as a candidate while the three-digit number is being input, and is selected by a user operation (see, for example, Patent Document 1).
JP 2002-94889 A

  By the way, even in the conventional three-digit number input channel selection, it is possible to directly select a desired service from all the services provided, but it is necessary to input all three-digit numbers. Therefore, there is a problem that the user has to perform many operations compared to other channel selection methods.

  Accordingly, an object of the present invention is to provide a digital broadcast receiving apparatus and a digital broadcast receiving method capable of simplifying the channel selection based on the three-digit number of a digital broadcast program as much as possible.

  In order to achieve the above object, the digital broadcast receiving apparatus of the present invention is a digital broadcast receiving apparatus that selects and receives a digital broadcast program by inputting a three-digit number, and inputs the three-digit number of the digital broadcast program. And a channel selection unit that selects the digital broadcast program with reference to program sharing information between the digital broadcast programs when a three-digit number is input by the input unit.

  Here, for example, the program sharing information is event sharing information of EIT (Event Information Table) information included in SI (Service Information) information broadcast together with the digital broadcast program.

  The digital broadcast receiving method of the present invention is a digital broadcast receiving method for selecting and receiving a digital broadcast program by inputting a three-digit number, the step of inputting the three-digit number of the digital broadcast program; Selecting a digital broadcast program with reference to program sharing information between the digital broadcast programs when a three-digit number is input by the input means.

  According to the digital broadcast receiving apparatus and the digital broadcast receiving method of the present invention, when a three-digit number of a digital broadcast program is input, the digital broadcast program is referred to by referring to the program sharing information between the digital broadcast programs included in the program guide data. Since the channel selection is performed, it is possible to identify one service to be selected even while the three-digit number is being input, and it is possible to complete the channel selection with fewer operations than the conventional three-digit number input channel selection.

Embodiment 1 FIG.
Next, Embodiment 1 of the present invention will be described.

  FIG. 1 is a block diagram showing a configuration of a digital broadcast receiving apparatus according to Embodiment 1 of the present invention.

  In FIG. 1, the digital broadcast receiving apparatus includes a receiving unit 11 that receives program data and program guide data of a digital broadcast program, a channel selection unit 12 that selects a digital broadcast program, and three users. An input receiving unit 13 for receiving various operation commands such as a channel channel selection command and a volume adjustment command by setting a digit number input channel selection mode, and a digital broadcast received by the reception unit 11 are transmitted. SI information storage unit 14 that stores SI (Service Information) information such as EIT (Event Information Table) as program guide data, and a user or the like by setting a three-digit number input channel selection mode or by selecting a three-digit number input channel A remote controller 15 is provided as input means for transmitting various operation commands such as a channel selection command and a volume adjustment command.

  FIG. 2 shows an example of SI (Service Information) information received by the digital broadcast receiving apparatus.

  SI (Service Information) information 21 is inserted into a digital broadcast program in the form of a section separately from video and audio within a broadcast radio wave. The SI information 21 is extracted through the reception unit 11 and the channel selection unit 12 and input to the SI information storage unit 14 and stored as digital data. The SI information 21 includes an EIT (Event Information Table) that is the basis of an electronic program guide table for each program. The EIT (Event Information Table) includes an event name (program name) and event content (program content). Information on events (programs) is described. The EIT also includes event sharing information, which is program sharing information for designating a service for broadcasting a program having the same content as other services (channels), and is described in event_group_descriptor.

  In event_group_descriptor, information other than event sharing information is also described, but is distinguished by group_type. That is, when 1 is written in group_type, it can be determined as event sharing information. When group_type is 1, the event sharing destination service_id and the event sharing destination event_id are described together.

  Next, the operation of the first embodiment will be described.

  FIG. 3 is a flowchart showing a program tuning procedure based on a three-digit number in the digital broadcast receiving apparatus according to the first embodiment.

  First, the channel selection unit 12 receives a channel selection command from the user from the remote controller 15 via the input reception unit 13. When the channel selection command is received from the remote control 15, the channel selection command is provided on the remote control 15. It is determined whether or not the command is for a three-digit number input channel selection mode by pressing a three-digit number input channel selection mode selection key or the like (S310 “YES”). Here, if it is not the three-digit number input channel selection mode (S310 “NO”), the channel selection is performed in another channel selection mode, for example, the channel channel (service) number direct input mode (S315). Then, the tuning process is terminated.

  On the other hand, in the three-digit number input channel selection mode (S310 “YES”), the channel selection unit 12 inputs the three-digit number key (0-9) from the remote controller or the like by a user operation. After that, the input of the numeric key is accepted one by one through the input receiving unit 13 (S320).

  When there is an input of one digit of the numeric key, the channel selection unit 12 searches for a service (channel) to be selected based on the number input for each digit (S330), and selects the service to be selected. Whether or not is detected is determined (S340). Here, in the process of step 330 for searching for a service to be selected, the channel selection unit 12 accumulates the input numbers and recognizes them as the third digit, the second digit, and the first digit in order. Search for services to be selected based on the information. The service (channel) for inputting a three-digit number may exceptionally have four or more digits, but basically, since it can be uniquely identified by three digits, it is basically not repeated three or more times.

  FIG. 4 is a diagram illustrating an example of a state in which a matching service is searched from the service list.

  In FIG. 4, reference numeral 410 denotes a list of all services with a three-digit number input. For example, there are programs “111, 112, 121, 122, 123, 201, 211, 333,. Shall.

  Here, when “2” is input as the first digit by the user, a search is performed for a service whose third digit starts with “2”, and the tuning unit 12 selects “201” and “211” as the search results. Get a station capable service 420.

  If "2" is entered in the third digit and "1" is entered in the second digit, a search for services starting with "2" in the third digit and "1" in the second digit is performed. As a result of the search, the selectable service 430 “211” is obtained. If there is no service to be selected in the middle of input, it is possible to notify the user that there is no service to be selected by displaying a message or the like.

  Returning to FIG. 3, when the channel selection target service is not detected (S340 “NO”), the channel selection unit 12 returns to the process of step S320 and accepts the input of the next numeric key by the user operation.

  On the other hand, when the channel selection target service is detected (S340 “YES”), the channel selection unit 12 refers to the event sharing information described in the EIT information in the SI information stored in the SI information storage unit 15. Then, it is determined whether there are a plurality of tuning target services sharing the same event among the detected tuning target services (S350).

  When there are a plurality of channel selection target services sharing the same event (S350 “YES”), the channel selection unit 12 performs a process of combining the channel selection target services having the same event sharing information into one (S360). For example, as shown in FIG. 4, when the user inputs up to “12”, the channel selection unit 12 uses “121” as the channel selection target service sharing the same event. When there are three, “122” and “123”, for example, they are grouped into “121” having the smallest number. Needless to say, it may be arranged in “122” or a new service “129” that does not overlap.

  When there are not a plurality of channel selection target services sharing the same event (S350 “NO”), the channel selection unit 12 does not perform the process of combining the channel selection target services having the same event sharing information in S360 into one. .

  Next, the process of step 360 for collecting the channel selection target services having the same event sharing information into one will be described.

  FIG. 5 is a diagram illustrating an example of a service and a broadcast event when an event is shared.

  In FIG. 5, the three digit numbers 111 and 112 (channels) correspond to broadcast events A and B, respectively. The three digit numbers 121, 122, and 123 services (channels) are The event C of the broadcast event is shared, that is, it corresponds to the same broadcast program, and a common event is shared by the event sharing information.

  In FIG. 5, the selectable service 510 is in a state in which “1” is input in the third digit, and five services are selected as a result of the search for services starting with “1” in the third digit. It is targeted for the station.

  However, since the services 121, 122, and 123 broadcast the same event by sharing the event using the EIT information of the SI information, there are actually only three types of events (programs) A, B, and C.

  For this reason, in this embodiment, as shown in FIG. 2, based on the event sharing information of group_type, service_id, and event_id in the event_group_descriptor described in EIT that is one of SI information, A process of detecting sharing and removing duplication of services broadcasting the same event (program) is performed.

  As a result, according to the present embodiment, the services to be selected can be grouped into three services like the selectable service 520. It should be noted that a method of selecting one service from a plurality of services sharing the same broadcast event may be given priority to the event sharing destination, or to the service with a smaller service number.

  Then, the channel selection unit 12 determines whether or not the channel selection target service can be specified as one (S370), and when the channel selection target service is not specified as one broadcast event (S370 “NO”), the process proceeds to step S320. Returning to the process, the process returns to accepting the input of numbers by the user operation. On the other hand, when the channel selection target service is specified as one broadcast event (S370 “YES”), the channel selection target service specified as one of those is selected. (S380).

  As a result, for example, when the user inputs up to “12”, as shown in the selectable service 510 in FIG. 5, “121”, “122” are selected as the channel selection target services that share the same event by the channel selection unit 12. ”And“ 123 ”, even if there are three,“ 123 ”having the smallest number as shown in the selectable service 520 in FIG. Once input, the broadcast event C can be selected by the service (channel) “121”.

  As described above, according to the first embodiment, when a user tries to select one service from a number of unspecified services, even if the three-digit number is being entered, it is described in the EIT information. By referencing the shared event information, multiple services to be selected with the same event (program) are combined into one, so it is possible to select with fewer operations than the conventional three-digit number input channel selection. You can complete the station.

  In the above embodiment, by referring to the event sharing information described in the EIT information at the time of event (program) channel selection, a plurality of channel selection target services having the same event (program) are combined into one. In the present invention, the present invention is not limited to this, but the user selects a specific service from a plurality of services as in the case of presenting each program guide service information such as EPG (electronic program guide). Of course, by referring to the event sharing information, a plurality of channel selection services having the same event (program) may be combined into one.

  In the above embodiment, as shown in FIG. 3, when the channel selection target service is detected in the determination in step 340 (S340 “YES”), the SI information storage unit 15 is referred to in step S350. Thus, it has been described that it is determined whether there are a plurality of channel selection target services that share the same event among the detected channel selection target services. However, the present invention is not limited to this, for example, FIG. When a channel selection target service is detected in the determination of step 340 (S340 “YES”), it is subsequently determined whether or not one channel selection target service has been identified (S345). If the station target service is not specified as one broadcast event (S345 “NO”), the SI information storage unit 15 is referred to in step S350, and the same event is detected among the detected channel selection target services. If there is a plurality of channel selection target services that share the channel, and if the channel selection target service is specified as one broadcast event (S345 “YES”), the processing of steps 350 to 370 is skipped. Of course, the process of selecting the channel selection target service specified in one of the steps S380 may be performed.

  In this embodiment, as an example of the program sharing information, the event sharing information of the EIT (Event Information Table) information included in the SI (Service Information) information broadcast together with the digital broadcast program has been described. Of course, the program sharing information may be supplied via the Internet or the like.
