Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The digital broadcasting system according to the present invention includes a television broadcasting transmission system 1, a data broadcasting transmission system 2, a CM video material 3, a MUX (Multiplexer) 4, a transmitter 5, CM server 6 is provided. The receiver includes server-type receivers 7A, 7B, and 7C and BB (Broadband) connection receivers 8B and 8C that are provided in the respective areas.

  The television broadcast transmission system 1 is a digital broadcast transmission system that transmits terrestrial digital broadcasts. The data broadcast transmission system 2 is a broadcast transmission system that provides a storage type data broadcast service. Based on BML (Broadcast Markup Language) provided in real time by the broadcast wave of the TV broadcast transmission system 1, characters and moving images of the storage type data are displayed in association with the TV screen. . The CM video material 3 stores material videos of a plurality of regional CMs and regional common CMs having regional identification information. The MUX 4 multiplexes transmission data from the television broadcast transmission system 1 and the data broadcast transmission system 2, and the multiplexed data is transmitted and encoded via the transmitter 5 and then transmitted as a broadcast wave.

  On the other hand, the server-type receivers 7A, 7B, and 7C are digital broadcast receivers having a storage-type data broadcast reception function including a storage device such as a hard disk. The regional CM server 6 is a server device that is provided by, for example, an ISP (Internet Service Provider) and transmits regional commercials in response to a request from a receiver. The regional CM server 6 forms a plurality of mirror sites so that accesses are concentrated in a short time. The BB connection receivers 8B and 8C are digital broadcast receivers connected to the regional CM server 6 via a broadband line.

Next, the operation of the digital broadcasting system configured as described above will be described. FIG. 2 is a sequence diagram showing the procedure and contents of CM broadcasting by region in the digital broadcasting system.
First, in step S2a, the data broadcasting transmission system 2 determines the CM for each region (for example, CM-a, CM-b, CM-c: A area) during a pre-allocated period (for example, a free time of broadcasting such as midnight). , CM material corresponding to B district and C district). At this time, CM-a, b, and c are sent together with area identification information (for example, a zip code) corresponding to each area. When the server-type receivers 7A, 7B, and 7C receive CM-a, b, and c in step S2b, the server-type receivers 7A, 7B, and 7C collate with area identification information set in advance in each receiver to detect CMs corresponding to the areas. In step S2c, only the detected regional CMs are stored in the storage device. That is, the server type receiver 7A existing in the A area has CM-a, the server type receiver 7B existing in the B area has CM-b, and the server type receiver 7C in the C area has CM-c. Each is accumulated.

  In this state, when the television broadcast transmission system 1 detects a predetermined time before the start time of the broadcast frame of the regional CM in step S2d, in step S2e, the television broadcast transmission system 1 generates a trigger signal for instructing the selective display of the regional CM. The inserted BML is transmitted on a broadcast wave. When the receiver detects the trigger signal from the BML included in the received broadcast wave, in step S2f, the receiver determines whether the regional CM is accumulated in the storage device. If it is determined that the regional CMs are accumulated, the process proceeds to step S2j, and the accumulated regional CMs are read and displayed based on the instruction by the detected trigger signal. Thereby, in the server type receivers 7A, 7B, and 7C, CM-a, CM-b, and CM-c, which are CMs for each region, are displayed at the start time of the broadcast frame for each region.

  On the other hand, if it is determined in step S2f that the regional CM is not accumulated, the process proceeds to step S2g to determine whether or not the regional commercial server 6 is connected via the broadband line. In this determination, if the receiver is connected to the regional CM server 6, the process proceeds to step S2h, and a regional CM acquisition request is transmitted to the regional CM server 6 together with the regional identification information. In step S2i, the regional CM server 6 transmits the corresponding regional CM based on the region identification information in response to the acquisition request. In this way, in the BB connection receivers 8B and 8C, CM-b and CM-c, which are regional CMs corresponding to the respective regions, are acquired from the regional CM server 6, and based on the trigger signal in step S2j. Thus, the acquired CM-b and CM-c are displayed in the broadcast frame of the CM for each region.

  In step S2k, the television broadcast transmission system 1 incorporates the regional common CM into the regional CM broadcast frame and transmits it on the broadcast wave. In the receiver determined that the regional CM is not accumulated and is not connected to the regional CM server 6 via the broadband line by the determination in step S2f and step S2g, the process proceeds to step S2l. The above-mentioned regional common CM to be transmitted is displayed in a broadcast frame of another CM.

  As described above, in the present invention, the data broadcast transmission system 2 transmits a plurality of regional CMs (CM-a, CM-b, CM-c) on a broadcast wave using a period allocated in advance. Then, the CM for each area is detected and accumulated on the receiver side based on the area identification information. Then, the television broadcast transmission system 1 transmits a trigger signal on a broadcast wave a predetermined time before the broadcast frame of the regional CM, and the receiver accumulates the above-mentioned in the broadcast frame of the regional CM based on this trigger signal. Displays regional CMs. Also, the television broadcast transmission system 1 transmits the regional common CM to the regional CM broadcast frame, and the receiver not storing the regional CM displays the regional common CM in the regional CM broadcast frame. I have to.

  Therefore, according to the above-described embodiment, it is possible to realize the provision of CM by a small area unit such as a municipality by a server push type targeting an unspecified large number. For example, commercials by region at the postal code level are possible, and television broadcasting can be used for advertisements and regional communication of small and medium-sized retail stores that have municipalities as commercial areas. For this reason, the number of people who use TV advertisements increases and the use of detailed broadcast media by region makes it possible to revitalize the region.

  In addition, even if the regional CM is not stored in the receiver, the receiver connected to the regional CM server 6 via the broadband line can receive the regional CM from the regional CM server 6 via the broadband line in advance. Try to get into. In this way, since the CM for each region can be acquired in a short time even when the trigger signal is received by using the broadband line, the CM for each region can be provided more reliably.

  The present invention is not limited to the above embodiment. For example, as a material for each region, it is possible to provide not only a CM but also an information program related to a specific region by replacing it with a common program. The configuration and operation procedure of the digital broadcasting system and the contents thereof can be variously modified and implemented without departing from the present invention.

  In short, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
