Description

  The present invention relates to a digital broadcast receiving apparatus for receiving a digital broadcast wave, and in particular, a storage-type broadcast reception function that enables data processing when divided data included in a broadcast wave satisfies a predetermined condition and is stored. It is related with the digital broadcast receiver for mobile bodies provided with.

  In recent years, the spread of digital broadcasting has been promoted. For example, in Japan, except for some areas, terrestrial analog broadcasting was terminated in 2011, and transition to terrestrial digital broadcasting was performed. Along with this, digital broadcasting receivers for mobile bodies mounted on car navigation systems, mobile phones and the like have been widely developed.

  In digital broadcasting, in addition to real-time broadcasting (for example, terrestrial digital broadcasting) that can be received and processed immediately, such as viewing and displaying subtitles and data broadcasting, it receives segmented data sent by broadcast waves There is a storage-type broadcast that can be recorded once (hereinafter referred to as “storage”) and data processing such as reproduction can be performed when the divided data has been stored after satisfying a predetermined condition.

  As digital broadcasting including storage type broadcasting, for example, there are V-High multimedia broadcasting and V-Low multimedia broadcasting which are being realized mainly by the Ministry of Internal Affairs and Communications in Japan. In the storage type broadcasting, it is considered to transmit a TS (transport stream) file or the like as divided data.

  In digital broadcasting, a plurality of services (service_id) can be defined for one broadcasting station, and only one program (event_id) can be broadcast simultaneously for one service. In other words, a plurality of programs can be broadcast at the same time as the number of services.

  For example, in terrestrial digital broadcasting, there are many cases where two to five services are used for one broadcasting station. However, since the same program is often broadcast by a plurality of services, in many cases, only one program or only two programs are broadcast per broadcasting station.

  For this reason, in the scheduled recording of digital terrestrial broadcasting, when the recording date / time comes, the receiver selects and records the program to be recorded (= content), and the user views the same program as the recorded program. is there. If the user wants to view a program different from the recorded program, for example, two or more tuners are installed in the receiver, and the role is divided between a tuner that operates for recording and a tuner that operates for viewing.

  In relation to the above, in Patent Document 1, it is determined whether or not the recorded program matches the viewing program, and the recording is stopped when the user starts viewing the recorded program while recording the recorded program. An automatic recording apparatus is disclosed.

JP 2008-228085 A

  On the other hand, in multimedia broadcasting, a plurality of software providers are mixed and broadcast in one frequency band. That is, it is assumed that an operation in which a plurality of programs can be viewed in one frequency band is generally used. For this reason, an operation mode in which real-time broadcasting and storage broadcasting are mixed in one frequency band is assumed.

  In such a case, even if a plurality of tuners are not provided, the user can simultaneously store (record data including recording) and view a plurality of programs in one frequency band. However, when they are mixed, the bandwidth that can be used for transmission of stored data is limited compared to the case where they are not mixed.

  For example, in V-Low multimedia broadcasting, an operation for transmitting a video of a VGA (Video Graphics Array) as a storage-type broadcast in one segment is being studied. However, when large-capacity content such as moving image information is transmitted in a limited band, it is assumed that it takes a long time to complete the accumulation.

  For this reason, a receiver for storage-type broadcasting is equipped with a function of reserving storage from a list screen for content storage reservation such as a TV latte field and starting storage when the storage date and time comes. Presumed. If the execution of storage from the storage reservation is applied to the prior art, the reserved program is selected and the storage is started when the storage date / time comes.

  However, even in this case, since it takes several minutes to several hours from the start of accumulation to the completion of accumulation, it is difficult to perform accumulation and reproduction of accumulation type data in parallel. Even if it can be done, the stored data can only be reproduced repeatedly. For this reason, there is a problem that a waiting time of the user occurs during the accumulation process.

In addition, storage-type data, which is data that is split and transmitted and recorded on the recording medium on the receiving side and then combined and generated, is generated by recording and combining data included in the broadcast wave and recorded in the recording unit An accumulation processing unit. In addition, when the generation of storage type data is started, the reproduction is performed by extracting the image / sound data excluding the storage type data from the broadcast wave in the same frequency band as the broadcast wave used for the generation of the storage type data and playing it back. In order to achieve the above object, the reproduction control unit includes the image / audio data that can be extracted from a broadcast wave in the same frequency band as the broadcast wave used for generating the storage type data. The image / sound data satisfying a pre-accepted condition is extracted and reproduced.

As shown in the block diagram of FIG. 1, the in-vehicle receiving device 100 of the present invention can connect a diversity antenna 1 as an external device.

  The on-vehicle receiving device 100 includes at least a tuner 11 (= broadcast receiving unit), a demodulating unit 12 (= broadcast receiving unit), an HDD 13 (= recording unit), a CPU 14, a RAM 15, a ROM 16, an audio filter 17, an audio decoder 18, and a video. A filter 19, a video decoder 20, a data filter 21, a data decoder 22, an output unit 23, and an operation input unit 24 are provided.

  However, since the present invention does not mention the reproduction function of the stored content, an embodiment in which the reproduction function is provided in another receiver may be used. In this case, an audio filter, an audio decode, a video filter, a video decoder, or the like is not required for a receiver that stores content.

  The tuner 11 receives a terrestrial digital broadcast signal from the diversity antenna 1 and selects a channel on a desired physical channel (= frequency band). Further, the tuner 11 monitors whether or not broadcast waves can be received on the selected physical channel. Specifically, for example, when a vehicle equipped with the in-vehicle receiving device 100 straddles a reception area or the like and the electric field intensity of the broadcast wave received so far falls below a predetermined threshold, it is considered that reception is impossible. .

  The demodulator 12 demodulates and error-corrects the selected signal input from the tuner 11 and outputs each TS of one segment and 12 segments. The TS demodulated by the demodulator 12 is given to an audio filter 17, a video filter 19, and a data filter 21 described later.

  The CPU 14 is an arithmetic processing device that performs various calculations, processes, and controls. The CPU 14 organically controls the driving of each member of the in-vehicle receiving device 100 and performs overall control of broadcast reception processing and the like.

  The RAM 15 is a readable / writable recording medium used for a work memory of the CPU 14.

  The ROM 16 is a read-only recording medium that stores a control program executed by the CPU 14.

  The audio filter 17 extracts only audio data from the TS output from the demodulator 12. The audio decoder 18 decodes the extracted audio data to generate a digital audio signal, and provides it to the output unit 23 described later.

  The video filter 19 extracts only video data from the TS output from the demodulator 12. The video decoder 20 decodes the extracted video data to generate a digital image signal, and provides it to the output unit 23 described later.

  The data filter 21 extracts data such as transmission parameters, NIT (Network Information Table), program information, and the like from the TS output from the demodulator 12. The data decoder 22 decodes the extracted data. The decrypted data is recorded in the HDD 13, RAM 15 or the like.

<2. About the configuration of the function section>
Here, the relationship among the functional units for performing the storage process and the reproduction control process according to the embodiment of the present invention will be described with reference to the functional block diagram of FIG. In FIG. 2, the functional blocks illustrated inside the CPU 14 represent functional units realized by the CPU 14 executing a predetermined program.

  As shown in FIG. 2, the accumulation process and the reproduction control process of the present embodiment are performed by a search unit 14a (= reception control unit), an accumulation processing unit 14b, and a reproduction control unit 14c.

  The search unit 14a performs a search process for trying to receive a predetermined broadcast wave. The search unit 14a analyzes a receivable physical channel and uses a channel selection candidate table (= related information) (not shown) to distribute information by a software provider (for example, a broadcasting station) instructed by the user. Attempt to receive the broadcast wave band.

  The channel selection candidate table is a table in which frequency bands to be searched for each software provider are associated with each other. This frequency band is obtained from the NIT of the broadcast wave. There may be a plurality of frequency bands corresponding to one software provider.

  When reception is successful, reception of this broadcast wave is started. If reception fails, the search unit 14a attempts to receive a broadcast wave using an unchecked frequency band included in the channel selection candidate table.

  In the following, regarding the term “channel selection”, the operation of changing a viewing program without changing the frequency band in a broadcasting form in which a plurality of programs are broadcast in one frequency band is also referred to as “channel selection”. To do.

  The storage processing unit 14b extracts the storage-type data transmitted by the storage-type broadcast from the broadcast data extracted by the data filter 21 after being searched by the search unit 14a. For example, it is recorded in the HDD 13. In addition, the storage processing unit 14b has a function of combining the storage-type data that have been divided and transmitted so that the data format can be processed.

  The accumulation processing unit 14b accepts an accumulation reservation from the user, and records information specifying a program (service) in the accumulation reservation information management table (FIG. 3). The storage reservation is made by displaying a screen like a latte field for stored content and accepting a user operation.

  FIG. 3 is a table showing an example of the storage reservation information management table generated by the storage processing unit 14b. As shown in FIG. 3, it is assumed that a software provider and a program can be uniquely specified by service_id (software provider identification ID) and event_id (program identification ID).

  In addition to the broadcast date and time of the stored program, the storage reservation information management table records the frequency band in which the broadcast is performed. In the example of FIG. 3, it is shown that a reservation for accumulation of a program broadcast in the frequency band 92.00 MHz is performed at 14:15 to 16:00 on 2011/06/06.

  FIG. 4 is a schematic diagram showing an image of the accumulation status of content (= accumulation type data) generated by the accumulation processing unit 14b. The event_id in FIG. 4 is an ID for identifying a program. The event_id is acquired from an EIT (Event Information Table) included in the received broadcast wave. Also, the squares in FIG. 4 represent processing units for the accumulation process. In the example of FIG. 4, accumulated data is filled in gray.

  For example, when attention is paid to the content 1 with event_id = 0x2000, the content is completed when all the seven squares are gray. In FIG. 4, contents 1 to 3 are defined for one program (event_id). However, it is assumed that the number of contents is determined from broadcast wave information.

  For example, in V-Low multimedia broadcasting, contents 1 to 3 can be detected from event_id, ex_event_id, and the like. The contents 1 to 3 are stored independently. Therefore, for example, even if the accumulation of the content 1 is not completed, the content 2 can be reproduced if the accumulation of the content 2 is completed.

  When the accumulation by the accumulation processing unit 14b is started, the reproduction control unit 14c searches for a real-time broadcast from the channel being selected. When a real-time broadcast is detected, each unit is controlled so that audio / image data of the corresponding broadcast is output from the output unit 23.

  The reproduction control unit 14c searches and manages real-time broadcasting by generating a viewing program information management table shown in FIG. 5, for example. Note that the generation / update timing of the viewing program information management table may be constantly updated, or may be updated when accumulation is started.

  As shown in FIG. 5, the viewing program information management table is configured to include a service_id of real-time broadcasting, a frequency band, a current program, and a next program. The event_id included in the columns of the current program and the next program is an ID for identifying the program. Whether or not the broadcast is real-time is determined based on, for example, a service ID value or information obtained from EIT or the like.

  In other words, all the programs shown in FIG. 5 are not programs using storage-type data distributed in storage-type broadcasting, but are viewed in real time without requiring storage processing, such as television broadcasting and radio broadcasting. Indicates that this is a possible program.

In addition, when the frequency shown in FIG. 5 is not determined for each program but is a broadcasting format determined for each software provider, the viewing program information management table may not include the frequency band. In this case, the channel selection candidate table (not shown) is used to determine the frequency band of the software provider of the program for which storage reservation has been made, and reception is attempted.
<3. About storage processing>
Here, the processing flow of the accumulation processing performed by the in-vehicle receiving device 100 according to the embodiment of the present invention will be described with reference to the flowchart of FIG.

  The processing flow of the present embodiment can be started at an arbitrary timing when the table shown in FIG. 3 has already been created by the receiver and the in-vehicle receiving device 100 is in the energized state.

  After the start of this processing, in step S110, the storage processing unit 14b refers to the storage reservation information management table and determines the storage reservation that needs to be executed most recently. For example, if the current date and time is 16:00 on June 06, 2011, event_id = 0x2000 in FIG. 3 is the corresponding storage reservation.

  Next, in step S120, the accumulation processing unit 14b proceeds to step S130 when the accumulation execution date / time indicated by the accumulation reservation determined in step S110 is reached. If the accumulation execution date / time has not been reached, monitoring continues.

  The accumulation execution date and time may be different from the broadcast start time of the rebroadcast to be accumulated. Specifically, for example, when the search process is performed before the broadcast start time and accumulation starts at the same time as the broadcast start time, the search process start time is set as the accumulation execution date and time.

  In this processing flow, if the accumulation execution date / time is not reached, it is continuously monitored whether the accumulation execution date / time is reached again. However, a process in place of step S120 is performed using a timer according to the accumulation execution date / time. But you can.

  Next, in step S130, the accumulation processing unit 14b refers to the broadcast station information table and searches for an unsearched search frequency. In the initial search, the search may be executed using the first search frequency described in the channel selection candidate table.

  If there is an unsearched search frequency, the process proceeds to step S140. If there is no unsearched search frequency, this process is terminated. Or the form which transfers to step S130 again may be sufficient. This is because the reception state may be temporarily deteriorated in mobile reception or the like, and the search may be successful by repeating the search loop.

  Next, in step S140, the accumulation processing unit 14b determines a search frequency and executes a search.

Next, in step S150, the accumulation processing unit 14b determines whether the search has been successful and the program to be accumulated has been received. If it can be received, the accumulation process is started and the process proceeds to the process flow of FIG. If the program to be stored cannot be received due to a poor radio wave condition or the like, the process proceeds to step S130 again.
<4. About playback control processing>
Here, a processing flow of the reproduction control process performed by the in-vehicle receiving device 100 according to the embodiment of the present invention will be described with reference to the flowchart of FIG.

  The processing flow of the present embodiment is started when a program to be accumulated can be received in step S150 of FIG.

  This process is performed in parallel with the accumulation process started in step S150 of FIG. That is, in parallel with the execution of storage, a real-time broadcast that matches the viewing conditions is searched, and when a matching program is found, the user can view it. The accumulation process is terminated when the accumulated content is completed or when the program end date / time is reached.

  After the start of this processing, in step S210, the playback control unit 14c determines whether or not the programs included in the viewing program information management table shown in FIG. It is determined whether there is a program to be executed.

  If there is no undetermined program, this process is terminated. If there is an undetermined program, the playback control unit 14c compares the frequency band being selected used for the accumulation process with the frequency band of the undetermined program determined in step S210 in step S220. , It is determined whether or not they match.

  If they do not match, the process proceeds to step S210 again. If they match, in step S230, the playback control unit 14c determines whether or not the program determined in step S210 satisfies preset viewing conditions (program genre and the like). For example, if the genre of sports is set in advance as a viewing condition by the user and the program determined in step S210 is baseball, it is considered that the condition is satisfied.

  Alternatively, the viewing condition may be automatically determined by the receiver. For example, in a broadcasting mode in which a typical service (primary service) exists for each broadcasting station, such as terrestrial digital broadcasting, the condition setting is made so that the primary service is detected by the receiver and the primary service is preferentially selected. The form to perform may be sufficient.

  When the condition is not satisfied, the process proceeds to step S210 again. If the condition is satisfied, the playback control unit 14c controls each unit (demodulation unit 12 and the like) to perform demodulation and output from the output unit 23 so that the user can view the determined real-time broadcast program in step S240. To do.

  According to the present embodiment described above, in parallel with the execution of storage, a real-time broadcast program different from the storage broadcast is played back so that the user can view it. However, if a different frequency band is selected by one tuner, the storage is interrupted, so the program is limited to the same frequency band. As a result, the user can view an immediately-viewed program while continuing to store the storage-type broadcast that cannot be immediately viewed.

Further, according to the present embodiment, when determining a program that is immediately viewed, the priority program is determined based on a preset condition. For this reason, it is possible to preferentially reproduce programs presumed to be highly interested by the user. This is particularly effective in a broadcasting mode in which there is a high possibility that the contents of a program broadcast in the same frequency band at the time of storage reservation are not known, such as V-Low multimedia broadcasting.
