(Background of Obtaining One Form of the Present Disclosure)
2. Description of the Related Art In recent years, due to the spread of high-speed network lines such as FTTH (Fiber To The Home)/HFC (Hybrid Fiber Coaxial), pay broadcast service providers are providing IP (Internet Protocol) broadcasting services using high-speed network lines. .. On the other hand, a cable television broadcasting company that provides cable television broadcasting is performing broadcasting (also referred to as RF (Radio Frequency) broadcasting) via existing broadcasting waves, and suddenly ends RF broadcasting and switches to IP broadcasting. It is difficult to switch. Therefore, it is conceivable that a cable television broadcaster may continue RF broadcasting for cable television, carry out IP broadcasting in parallel, and gradually increase the number of IP broadcasting channels while reducing the number of RF broadcasting channels. Alternatively, it is conceivable that, for example, RF broadcasting for terrestrial broadcasting is left and other pay multi-channel broadcasting (for example, BS broadcasting, advanced BS broadcasting, cable television broadcasting) is transferred to IP broadcasting. From the above, it is assumed that RF broadcast and IP broadcast are operated in parallel, and a broadcast receiving device that receives a broadcast signal is also required to have a reception function corresponding to both broadcast signals (broadcast mode). Be done.

Further, when RF broadcasting and IP broadcasting are operated in parallel, there is a demand for a shared receiver capable of receiving both the RF broadcasting signal (RF broadcasting signal) and the IP broadcasting signal (IP broadcasting signal). To be done. In the shared receiver, it is desirable that the program content (also simply referred to as “program”) broadcast by the RF broadcast signal and the IP broadcast signal can be viewed without distinguishing which broadcast signal the program is. In this case, it is desirable that the program management information for managing the program of the RF broadcast signal and the program management information for managing the program of the IP broadcast signal can be handled without distinction. The program management information may have different formats depending on each broadcast signal. Even in this case, it is desirable that the shared receiver can easily manage the program of each broadcast signal.

In the following embodiment, a broadcast receiving apparatus and a broadcast receiving method that can easily manage the program management information by integrating it even if the formats of the program management information for a plurality of broadcast signals are different will be described.

The receiver 100 collects and acquires the program guide information I0 of the RF broadcast (S101). The receiver 100 collects and acquires the IP broadcast program guide information I0 (S102). The program guide information I0 for RF broadcast and IP broadcast may be program guide information based on EIT.

FIG. 8 is a flowchart showing an operation example at the time of collecting program guides of RF broadcasting. Here, an example is shown in which a TS format stream is received as an RF broadcast, but the same applies to the case of the TLV format.

The tuner 104 receives a stream of RF broadcast signals. The program guide management unit 126 acquires SI/PSI data from the stream and acquires (for example, extracts) NIT (Network Information Table) from the SI/PSI data via the demultiplexer 108 and the multimedia processing unit 110 (S201). ). The NIT describes the physical position and information of the channel such as frequency and modulation method. The NIT includes a service information list and includes information indicating what kind of channel is included. The NIT may include a service ID, a stream ID, and the like. Further, the program guide management unit 126 may acquire information (for example, stream type information, original network ID, contract information, etc.) included in the SI/PSI data and necessary for generating channel management information.

The program guide management unit 126 repeats or repeats the processing of S203 to S209 for the service information list, that is, one or more service IDs included in the NIT (S202). When the iterative process is completed for all the service IDs, the program guide management unit 126 ends the process of FIG.

When the corresponding service ID is not registered in the channel management information I1, that is, it is not registered, the program guide management unit 126 adds this service ID to the channel management information I1, that is, registers it (S203). In this case, the program guide management unit 126 also adds and registers other acquired information (for example, stream type information, original network ID, stream ID, contract information) to the channel management information I1.

The tuner 104 receives the stream including the TS packet corresponding to the service ID according to the instruction from the program guide management unit 126 (S204). The stream includes a stream in packet units (for example, TS packets). The demultiplexer 108 divides the stream and acquires TS packets.

The program guide management unit 126 acquires an EIT-sch (Actual) (hereinafter, also referred to as a unit “EIT”) as EIT information, which is information of its own service, from the TS packet acquired from the demultiplexer 108 (S205). The EIT may include the event ID and other information regarding the program content. The EIT includes, for example, information on program contents for 8 days. The information about other program contents may be information necessary for generating the program information management table I2, and may include, for example, start time information, duration information, program name information, short format description information, reservation information, and the like.

The program guide management unit 126 repeats the processes of S207 to S209 for the event information list, that is, one or more event IDs included in the EIT, or causes the processes to be repeated (S206). When the iterative process is completed for all event IDs, the program guide management unit 126 proceeds to S202.

The program guide management unit 126 determines whether or not the corresponding event ID is described in the program information management table I2, that is, whether or not this event ID has been managed (S207).

When the event ID is already managed, the program guide management unit 126 inherits the reservation information corresponding to this event ID from the program information management table I2, and manages the content of the received EIT for RF broadcasting in the program information management. The event ID column of Table I2 is overwritten and registered (S208). As a result, the information corresponding to the corresponding event ID is updated on the program information management table I2. It progresses to S206 after S208.

If the event ID has not been managed, the program guide management unit 126 additionally registers the content of the received EIT for RF broadcasting in the program information management table I2 as information corresponding to the new event ID (S209). It progresses to S206 after S209.

Since the EIT information includes, for example, information on programs for eight days, when the EIT information is acquired every day, the last day's information is not included in the EIT information on the previous day. Therefore, basically, the information for the last day may be added to the program information management table I2. It should be noted that the 7-day information that has not been changed and has been acquired the previous day may be overwritten in the program information management table I2 or may be omitted from registration, but if the reservation information is registered by the previous day. The registered reservation information is left as it is (inherited) without overwriting the reservation information. Further, when the receiver 100 performs the overwrite registration, even if there is a changed portion in the EIT, the receiver 100 can reflect the change and generate the program information management table I2. The same applies to the collection of program guides for IP broadcasting.

According to such an operation example at the time of collecting the program guide of the RF broadcast, the receiver 100, based on the program guide information I0 unique to the RF broadcast, has integrated program management information (channel management information I1) corresponding to a plurality of broadcast signals. , Program information management table I2, etc.) can be generated.

FIG. 9 is a flowchart showing an operation example at the time of collecting a program guide of IP broadcasting. Here, an example in which a TS format stream is received as the IP broadcast is illustrated, but the same applies to the case of the TLV format.

According to the instruction from the control unit 102, the IP communication unit 106 transmits a join message (eg, IGMP (Internet Group Management Protocol) join message) so as to participate in the multicast of the SI dedicated stream (S301). As a result, the receiver 100 participates in the multicast of the SI dedicated stream. The SI-dedicated stream includes SI/PSI data and does not include video data or the like included in normal program content.

The IP communication unit 106 receives a stream of IP broadcast signals. The program guide management unit 126 acquires SI/PSI data from the stream and acquires (for example, extracts) NIT (Network Information Table) from the SI/PSI data via the demultiplexer 108 and the multimedia processing unit 110. (S302). The NIT describes the physical position and information of the channel such as frequency and modulation method. The NIT includes a service information list and includes information indicating what kind of channel is included. The NIT may include a service ID, a stream ID, IP multicast information, and the like. Further, the IP multicast information corresponding to the service ID may be acquired from a server (not shown) as tuning control information in which a pair of the service ID and the IP multicast address to which the corresponding service is distributed is described. Further, the program guide management unit 126 may acquire information (for example, stream type information, contract information, original network ID, etc.) included in the SI/PSI data and necessary for generating channel management information.

The program guide management unit 126 repeats the processes of S304 to S310 or causes the service information lists, that is, one or more service IDs included in the NIT to be repeatedly executed (S303). When the iterative process is completed for all the service IDs, the program guide management unit 126 ends the process in FIG.

When the corresponding service ID is not registered in the channel management information I1, that is, it is not registered, the program guide management unit 126 adds this service ID to the channel management information I1, that is, registers it (S304). In this case, the program guide management unit 126 also adds and registers other acquired information (for example, stream type information, original network ID, stream ID, contract information) to the channel management information I1. The program guide management unit 126 also adds and registers the IP multicast information to the channel management information I1 (S305).

The program guide management unit 126 acquires the EIT from the SI dedicated stream corresponding to the corresponding service ID via the multimedia processing unit 110 (S306). The EIT may include the event ID and other information regarding the program content. The EIT includes, for example, information on program contents for 8 days. The information about other program contents may be information necessary for generating the program information management table I2, and may include, for example, start time information, duration information, program name information, short format description information, reservation information, and the like.

The program guide management unit 126 repeats the processes of S308 to S310 for the event information list, that is, one or more event IDs included in the EIT, or causes the processes to be repeated (S307). When the iterative process has been completed for all event IDs, the program guide management unit 126 proceeds to S303.

The program guide management unit 126 determines whether or not the corresponding event ID is described in the program information management table I2, that is, whether or not this event ID is already managed (S308).

When the event ID is already managed, the program guide management unit 126 inherits the reservation information corresponding to this event ID from the program information management table I2, and manages the contents of the received EIT for IP broadcasting in the program information management. The event ID column of Table I2 is overwritten and registered (S309). As a result, the information corresponding to the corresponding event ID is updated on the program information management table I2. It progresses to S307 after S309.

If the event ID has not been managed, the program guide management unit 126 additionally registers the content of the received EIT for IP broadcast in the program information management table I2 as information corresponding to the new event ID (S310). It progresses to S307 after S310.

According to the operation example at the time of collecting the program guide of the IP broadcast, the receiver 100, based on the program guide information I0 unique to the IP broadcast, has integrated program management information (channel management information I1) corresponding to a plurality of broadcast signals. , Program information management table I2, etc.) can be generated.

Therefore, the receiver 100 integrates the program management information between the RF broadcast and the IP broadcast by the operation at the time of collecting the program guide of the RF broadcast and the operation at the time of collecting the program guide of the IP broadcast, and can be commonly used for integration. Integrated program management information such as the electronic program guide G1 can be generated. By using the integrated program management information, the viewer can easily use the integrated program management information without paying special attention to a plurality of broadcast signals (for example, RF broadcast signal and IP broadcast signal).

Further, the receiver 100 participates in the multicast of the SI-dedicated stream in order to acquire the program management information for IP broadcasting, and thereby repeatedly communicates the Join message and the leave message of the multicast to receive a plurality of streams. Can be suppressed, and the processing load and network load can be reduced.

Further, even when the display format and management format of the program management information such as the RF broadcast program guide and the IP broadcast program guide are different, one channel management information I1 and the program information management table I2 are integrated. Can be aggregated into program management information. In this case, the format of at least one of the program management information of F broadcast and the program management information of IP broadcast may be converted to unify the formats and the integrated program management information may be generated.

Further, the program guide management unit 126 may generate the integrated electronic program guide G1 based on the program information management table I2. In this case, the program guide management unit 126 may display the information included in the program guide for IP broadcasting by integrating it with the information included in the program guide for RF signals. , An example of integrated program management information. As a result, the viewer can instruct the viewing and the like of the program by using the integrated electronic program guide G1 in the familiar EPG format, that is, by using the integrated program management information having the unified format.

FIG. 10 is a flowchart showing an operation example of resource management at the time of reservation by the receiver 100.

In FIG. 10, it is assumed that the program guide control unit 128 causes the integrated electronic program guide G1 shown in FIG. 6 to be displayed on the display unit and that the viewer receives a display instruction of the detailed screen G2 from the remote controller as the operation unit 122. To do. Then, it is assumed that the viewer confirms the display of the detailed screen G2 and performs the reservation operation using the remote controller. At the time of the operation in FIG. 10, the program management information (integrated program management information) shared by the RF broadcast and the IP broadcast has been generated.

The operation unit 122 (for example, a remote controller) receives a display instruction of the integrated electronic program guide G1 from the viewer, and the control unit 102 causes the display unit to display the integrated electronic program guide G1. The operation unit 122 receives an operation of selecting a predetermined program content displayed in the integrated electronic program guide G1, that is, a display instruction of the detailed screen G2 from the viewer, and the control unit 102 displays the detailed screen G2. To display. The viewer looks at the display unit and confirms the recording reservation, the viewing reservation, or the remote viewing reservation on the detailed screen G2. The operation unit 122 receives a reservation request input by the user (S401). The program guide control unit 128 acquires the reservation request information from the operation unit 122 (S402). The reservation request may be, for example, a recording reservation request, a viewing reservation request, or a remote viewing reservation request.

The program guide control unit 128 displays the information of the service ID, event ID, broadcast start time, and duration displayed on the detailed screen G2, that is, the program content selected on the integrated electronic program guide G1, in the channel management information I1, It is acquired from the integrated program management information such as the program information management table I2 (S403). The program guide controller 128 refers to the acquired reservation request and determines the type of reservation request (S404).

When the type of the reservation request is a recording reservation or a remote viewing reservation request, the program guide control unit 128 refers to the resource management information I4, and at the time of the broadcast start time and the broadcast end time of the corresponding program content, It is determined whether the resources of DTR1 or DTR2 are available (S405, S406). The broadcast end time may be derived, for example, by the program guide controller 128 by adding the broadcast start time and the duration.

When the resources of DTR1 or DTR2 are available (YES in S406), the program guide control unit 128 reserves a resource for recording reservation or remote viewing reservation of the program content corresponding to DTR1 or DTR2 (S407). In this case, the program guide control unit 128 registers the resource reservation information related to the resource reservation for this recording or remote viewing in the resource management information I4. In this case, the program guide control unit 128 instructs the program guide management unit 126 to set “2” (recording reservation) or “3” (remote viewing reservation) to the reservation information of the corresponding program content of the program information management table I2. It is registered and the corresponding time zone of DTR1 or DTR2 of the resource management information I4 is set to the reserved state.

The program guide control unit 128 causes the display unit to display, through the rendering unit 120, the reservation success information indicating that the resource reservation for recording or remote viewing has succeeded (S408).

On the other hand, when the resources of DTR1 and DTR2 are not available (NO in S406), the program guide control unit 128 transmits reservation failure information indicating that resource reservation for recording or remote viewing has failed via the rendering unit 120. And is displayed on the display unit (S409).

When the type of the reservation request is the request for viewing reservation in S404, the program guide control unit 128 refers to the resource management information I4, and determines the DECODE by the time between the broadcast start time and the broadcast end time of the corresponding program content. It is determined whether or not there is an available resource (S410, S411).

If the DECODE resource is available (YES in S411), the program guide control unit 128 reserves a resource for viewing reservation of the program content corresponding to DECODE (S412). In this case, the program guide control unit 128 registers the resource reservation information related to the resource reservation for this viewing in the resource management information I4. In this case, the program guide control unit 128 registers "1" (viewing reservation) in the reservation information of the corresponding program content of the program information management table I2, and sets the corresponding time zone of DECODE of the resource management information I4 to the reserved state. To

The program guide control unit 128 displays the reservation success information indicating that the resource reservation for viewing has succeeded on the display unit via the rendering unit 120 (S408).

On the other hand, when there is no free DECODE resource (NO in S411), the program guide control unit 128 displays reservation failure information indicating that resource reservation for viewing has failed on the display unit via the rendering unit 120. (S413).

According to such an operation example of resource management at the time of reservation, the receiver 100 uses the integrated program management information such as the generated integrated electronic program guide, so that the receiver 100 can generate a plurality of broadcast signals (for example, RF broadcast signal, IP It is possible to easily perform program content reservation, viewing, recording, remote viewing, etc. without paying special attention to (broadcast signal).

It is possible to provide viewers with a feeling of use with no functional difference. Then, the viewer can view the broadcast service by checking the integrated electronic program guide G1 without being aware of the broadcast source (for example, RF broadcast or IP broadcast). Further, the receiver 100 can separately acquire the program guide information I0 of the RF broadcast and the program guide information I0 of the IP broadcast, and manage them with one channel management information I1 and the program information management table TB1 in the receiver 100. Further, the receiver 100 uses the integrated program management information to share the resources (for example, the stream reception capability, the decoding capability, the program content display capability, and the recording capability) in the receiver 100 between the RF broadcast and the IP broadcast. it can. When the viewer makes a viewing reservation or a recording reservation using the integrated electronic program guide G1, the viewer can use the resources of the receiver 100 to the maximum without any conflict between the IP broadcasting and the RF broadcasting.

Further, the receiver 100 may operate the RF broadcast and the IP broadcast on the same application. Therefore, the receiver 100 confirms the program guides for both broadcast signals, as compared with the case where it takes time to view the program guides of the IP broadcasts because RF broadcast and IP broadcast are started by different applications. This can reduce the labor for Further, the receiver 100 can realize the operation of the program guide similar to the RF broadcast in the IP broadcast by using the integrated electronic program guide G1, and whether the channel selected for the viewer is the RF broadcast. Programs can be switched seamlessly without having to be aware of IP broadcasting.
