Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcasting tuner for receiving a digital broadcasting signal from a digital broadcasting and its adapter. In particular, the present invention relates to a digital broadcasting tuner and its adapter, which are characterized by a structure for outputting audio or video in a short time such as CM.

[0002]

2. Description of the Related Art In recent years, BS digital broadcasting and CS digital broadcasting have been put into practical use, and preparations for terrestrial digital broadcasting have been made. In addition, cable TVs are also considering switching to digital broadcasting. Digital broadcasting has excellent characteristics such as high image quality, multiple channels, high functionality, and high quality as compared with conventional analog broadcasting, and is expected as a mainstay of future broadcasting. In particular, satellite digital broadcasting (eg BS
In digital broadcasting and CS digital broadcasting, high-quality audio / video can be broadcast at a time over a wide area (for example, the entire Japanese archipelago) using a geostationary satellite.

At present, services of BS digital broadcasting and CS digital broadcasting have been started, but B
The spread of S digital broadcasting tuners and CS digital broadcasting tuners has not progressed as much as expected. One of the reasons may be that the price and the reception fee of the digital broadcasting tuner are high. It is possible that the advertiser bears the price and reception fee of this digital broadcasting tuner.

In Japanese Patent Laid-Open No. 5-284437, "A device in a television receiver for locally generating a commercial advertisement for display, which is for storing data indicating the commercial advertisement. Storage means; conversion means for converting the stored data into a video signal for display; control means coupled to the storage means for selectively supplying the data to the conversion means; And a switching means for switching the video signal to a display of the television receiver for a period of time, and the switching means is controlled by the control means ".

With the above-mentioned configuration, it is attempted to convey the commercial advertisement to the consumer at a very low cost for the advertiser.

On the other hand, as a business form of the digital broadcasting station, there are A type which collects a fixed reception fee from the viewer, and B type which inserts the audio / video for advertisement into the broadcast and collects the advertisement fee from the advertiser. There is a C type that collects a reception fee each time a viewer receives a broadcast. B type satellite digital broadcasting provides entertainment broadcasting to recipients,
The commercial image is interrupted at appropriate intervals between the entertainment broadcasts, and the advertisement fee is collected from the advertiser according to the time zone, the length of the commercial image, and the number of interruptions.

[0007]

When the commercial advertisement generating apparatus described above is used for the B type, the audio image for advertisement is interrupted to the audio image for broadcast regardless of the intention of the broadcasting station which uses the advertising revenue as a source. It will be displayed on the machine,
There is a possibility that the management of the broadcasting station will be extremely seriously damaged. Further, when used for the A type and the C type, it will be disappointing to the expectation of the viewer who pays a fee and wants to enjoy the broadcast video without interruption in the advertisement video. In addition, a method of broadcasting audio data for commercials along with entertainment broadcasting, which is performed by conventional analog terrestrial broadcasting, is adopted for satellite digital broadcasting in which a wide area (for example, the entire Japanese archipelago) is uniformly set as a broadcast receiving area. Then, the commercial image for the local market is broadcast to a wide area including an unrelated market.

[0008] By the way, in digital broadcasting, signals that have undergone advanced digital processing in order to realize multi-channel, high function, and high quality are transmitted. In the digital broadcast tuner, an internal digital signal processing chip performs predetermined digital processing (for example, MPEG processing) on the digital broadcast signal to generate an audio signal and a video signal. Normally, when audio and video is output to the receiver, the delay in the time required for this digital processing occurs uniformly, so that the user does not notice the time delay. However, when the user changes the channel, the digital signal processing chip is heavily loaded. In particular, since the digital broadcast signal is sent after being compressed, it takes time to generate the first one frame from the compressed data when the internal buffer memory is refreshed, and it currently takes 1 to 2 seconds. It takes time. Hereinafter, for convenience of explanation, this time is referred to as a blank time. The blank time can be shortened by the progress of electronic devices and the progress of digital processing, but it will not disappear. The same blank time occurs when the user turns on the power of the digital broadcasting tuner.

Based on the above knowledge, the applicant examined a CM broadcasting means different from the conventional one so that the advertiser can bear the price of the digital broadcasting tuner and the digital broadcasting reception fee.

The applicant has also considered a CM broadcasting means capable of broadcasting local CM audio / video for a specific area even in digital satellite broadcasting.

The present invention has been devised in view of the problems described above, and replaces a conventional digital broadcast tuner or its adapter (for example, a commercial advertisement generating device) with digital satellite broadcasting and digital terrestrial broadcasting. It aims to provide a digital broadcast tuner and its adapter that are well suited for operation and can insert audio and video data in a short time.

The output count record data output circuit 27 outputs the output record data recorded by the output count recording means 26 to the outside in response to an inquiry from the outside through the electronic communication network at a later date. Therefore, the outside (for example, an advertising company or a broadcasting company) can count how many people have watched the CM built in the digital broadcasting tuner from the digital broadcasting tuner in each house and what channel has been selected. Further, the outside can obtain reliable data without error such as so-called toilet time included in the conventional audience rating data.

The new audio / video data extraction circuit 24 extracts audio / video data contained in a specific band in the digital broadcast signal S2 and outputs it to the audio / video recording circuit 22. The audio / video recording circuit 22 determines that the audio-visual data should be recorded by comparing the area-specific information S19 output by the area-specific information storage circuit 25 with the area-specific information included in the audio-video data in a predetermined procedure. When judged, it is recorded in the storage means. Therefore, the audio / video recording circuit 22 determines that the audio / video data S1 unique to the area where the digital broadcasting tuner is located.

A certain CM audio / video is displayed on the receiver, and when a predetermined time elapses, the audio / video is displayed by a digital broadcast signal, so that the CM audio / video can be effectively shown to the viewer. Also, since the CM audio / video recorded in the audio / video recording circuit in advance during the blank time is displayed on the receiver, the viewer may have to wait an extra time to start watching the digital broadcast that he or she originally wants to watch. Less is. Further, the CM audio / video data can be recorded in the audio / video recording circuit by transmitting the CM audio / video data on a band allocated as an engineering slot in the BS digital broadcast signal S2 or a specific band of the CS wave. Therefore, the new CM audio / video can be shown to the viewer. In addition, the receivable area of the digital broadcast signal (for example, the whole area of the Japanese archipelago) is divided into a plurality of areas, the area code is recorded in the area specifying information storage circuit, and the audio / video recording circuit is selected according to the area code. Since the new audio / video data is recorded as audio / video data, it is possible to display the CM audio / video or the like for the viewer of a specific area to the receiver in the area to be shown to the viewer.
