[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcasting receiver system and a viewer living area setting information providing system.

[0002]

2. Description of the Related Art A digital broadcasting receiving apparatus for receiving digital broadcasting using satellites or terrestrial waves selects an arbitrary broadcasting wave from a plurality of broadcasting waves received through a dedicated antenna or a terrestrial antenna by a tuner. , Select any channel from the multiple channels included in the selected broadcast wave by demultiplexing, extract the digital signal of this selected channel, and decode it to output video / audio signals. .

By the way, in the digital broadcasting system,
Viewer's residential area (that is, the place where the broadcast receiver is installed)
It has been attempted to provide a service according to. In order to realize this service, the user needs to set viewer living area setting information (prefecture area code, area code, zip code, etc.) in the broadcast receiving apparatus. The prefectural area code in the viewer living area setting information is a code corresponding to the target area descriptor and is used to provide services such as weather forecast and election bulletin according to the area where the viewer lives in the data broadcasting service. . The area code is an area code corresponding to the emergency information signal, and is used in emergency warning broadcasting (EWS). The area code may be set by the user, or may be automatically set based on the prefecture code. The postal code is also used in the data broadcasting service to provide the service as described above according to the residential area of the viewer, and also in the interactive service to specify the nearest access point in the residential area. used.

[0004]

However, in the above conventional method, the user has to set the viewer living area setting information using the menu screen of the digital broadcast receiving apparatus, which is inconvenient. In particular, when the broadcast receiving device is configured as a portable type or an on-vehicle type and is to be moved, the user must reset the viewer living area setting information each time the user moves.

In view of the above circumstances, the present invention provides a digital broadcast receiving apparatus system and a viewer living area setting which can automatically set the viewer living area setting information in the digital broadcast receiving apparatus without any user operation. The purpose is to provide an information providing system.

[0006]

In order to solve the above-mentioned problems, a digital broadcast receiving apparatus system of the present invention connects an information communication terminal and a digital broadcast receiving apparatus so that data can be transmitted and received between them. The information communication terminal receives the viewer residence area setting information corresponding to the current position of the information communication terminal from the information providing center and supplies the viewer living area setting information to the receiving device, and the receiving device receives the viewer living area setting information. It is characterized by being configured to be stored in a memory.

Further, the digital broadcast receiving apparatus system of the present invention is configured such that the information communication terminal and the digital broadcast receiving apparatus are connected to each other so that data can be transmitted and received between them. It is configured to receive current position information of the information communication terminal and supply it to the receiving device, and the receiving device is configured to convert the current position information into viewer living area setting information and store it in a memory. To do.

With these configurations, since the viewer living area setting information or the current position information for obtaining the information is acquired through the information communication terminal, the viewer living area setting information can be obtained without the user operation. Can be automatically set in the digital broadcast receiver.

The receiving device is preferably configured to update the viewer living area setting information stored in the memory. For example, even if the installation area of the receiving device changes due to the user's move or the receiving device moves as a portable type or an in-vehicle type, the viewer living area setting information currently obtained is stored in the memory. If it is different from the setting information, the viewer living area setting information obtained at this time will be updated and recorded in the memory, and even if such movement occurs, it does not depend on the user operation. Viewer living area setting information is automatically set.

Further, the viewer living area setting information providing system of the present invention acquires information regarding the current position of the information communication terminal, and based on the information regarding the current position, the viewing necessary for receiving the regional service in digital broadcasting. It is characterized in that the person living area setting information is generated and the viewer living area setting information is transmitted to the information communication terminal.

Program information (program name, program name,
The program start time, program duration time, etc.) are supplied to the CPU 13. It should be noted that a plurality of channels are multiplexed in the transport stream, and the process for selecting an arbitrary channel from these is performed by selecting which packet ID in the transport stream the arbitrary channel is from PSI / SI. It is possible by taking out the data such as whether or not it is multiplexed with. Also, the selection of the transport stream can be performed based on the PSI / SI information.

The AV decoder 4 includes a video decoder for decoding a video stream and an audio decoder for decoding an audio stream. The video decoder decodes the input variable length code to obtain a quantized coefficient and a motion vector, and performs inverse DCT conversion and motion compensation control based on the motion vector. The audio decoder decodes the input coded signal to generate audio data. The video data generated by decoding is output to the video processing circuit 5, and the audio data is output to the audio processing circuit 6.

The video processing circuit 5 receives the video data from the AV decoder 4 and performs D / A conversion to generate a video signal, which is supplied to the display 17. The audio processing circuit 6 receives the audio data output from the AV decoder 4 and performs D / A conversion to generate, for example, a right (R) sound analog signal and a left (L) sound analog signal, and outputs the analog signal to a speaker.
