Description

Personal data receiver and method

The present invention relates to a data service of a satellite broadcasting system. Particularly, in case of performing a data service to a subscriber using a data service channel in a satellite reception system, IDENTIFICATION is given to only a specific subscriber or a specific subscriber group. This is to enable reception.

In general, a conventional apparatus includes a transmitter (3) for compressing video and audio signals sent from a broadcasting station (1), combined with digital data sent by a data service provider (2), and transmitted to the satellite (4). When the user selects the video and audio channel by separating the data received from (4), it is composed of a receiver 5 which extracts and demodulates the video and audio signal and sends it to the TV (TELEVISION).

Such a conventional apparatus compresses video and audio from a transmitter and transmits the data to a satellite by combining it with data sent from a data service provider. When the user selects the desired video and audio channels, the video and audio signals are extracted and demodulated and sent to the TV. On the other hand, when the user selects a data channel, the received data is output through the data output terminal. The data is received by the data receiver so that the user can receive the desired data. This method is operated so that anyone can receive the STB (SET TOP BOX) and the data receiver.

However, the conventional apparatus as described above has a problem that private data service is impossible due to security problems because anyone can receive the STB and the data receiver.

An object of the present invention is to solve the above-mentioned conventional problems, in particular, by giving a personal ID and a group ID for each data receiver so that only the selected subscriber can receive, rather than anyone can receive the corresponding individual or It is an object of the present invention to provide a personal data receiving apparatus and method in which a protection function is added so that only a group can receive and process data.

In order to achieve the above object, the present invention provides a personal data receiving apparatus comprising: a reception data discriminating unit for receiving and determining data; A storage unit for storing the received data; A display unit for displaying data stored in the storage unit; The display unit and the microcomputer for controlling the reception data discrimination unit are characterized in that the technical configuration.

On the other hand, the individual data receiving method includes a first step of determining whether or not the start code from the input data; A second step of returning to an initialization state where data is input if the codes do not match in the first step, and confirming a receiver designation type if the codes match; A third step of immediately storing the received data if the recipient designation type is general in the second step; A fourth step of comparing and discriminating a receivable ID and a group ID of the received data when the receiver designation type is a group in the second step; If the IDs compared in step 4 do not coincide with each other, the process returns to the initial stage of receiving data, and if the IDs match with each other, the received data is stored. If it is not an individual, as in the fourth step, the receivable ID and the personal ID are compared with each other, and if the IDs match, the fifth step of storing the received data in the storage unit and the ID compared in the fifth step are If it does not match, it returns to the initial state of receiving data.

The personal data receiving apparatus and method of the present invention transmits data to the terminal when the server requests a data through the terminal to obtain the information data required by the user, and the data is received by the data receiver. By retrieving the ID of the data received from the data receiver and storing the data in the storage unit only when the ID is the same as the user ID and outputting the data to the display unit, the reception data can be maintained and the service application range can be expanded. In addition, there is an effect that enables the service of personal information or additional information charged a fee.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment according to the technical idea of the individual data receiving apparatus and method of the present invention in detail as follows.

EXAMPLE

As shown in FIG. 3, the signal input terminal of the reception data discrimination unit 101 receives a signal from a satellite via an STB, and the signal output terminal of the reception data discrimination unit 101 is connected to the signal input terminal of the storage unit 102. The signal output terminal of the storage unit 102 is connected to the signal input terminal of the display unit 103, and the signal output terminal of the microcomputer 104 is connected to the signal input terminal of the storage unit 102 and is mutually connected to the display unit 103. This embodiment is connected so as to enable signal exchange.

First, the data service provider serving the data transmits the data by adding a reception type (TYPE) and a reception ID to the beginning of the data as shown in FIG. 3-1.

Accordingly, the data transmitted from the transmitter is received by the data receiver 100 to find the START CODE, and then referred to the receiver designation type.

The data received by the data receiver 100 is determined by the reception data discrimination unit 101. If the receiver designation type is general, the microcomputer 104 immediately stores the received data in the storage unit 102, and the data receiver. If the specified type of the data received at 100 is not general and is a group, the microcomputer 104 compares the group ID with the received data ID. If the compared IDs are the same, the microcomputer 104 receives the received data. The data is stored in the storage unit 102, and the received data is not stored when the compared IDs are not the same.

On the other hand, if the specified type of data received by the data receiver 100 is not general and is individual, the ID of the data received by the microcomputer 104 and the microcomputer 104 are stored in the same manner as in the case of the group described above. When the IDs are the same and the IDs are the same, the microcomputer 104 stores the received data in the storage unit 102. If the IDs are not the same, the received data is not stored.

When the ID of the received data and the ID stored in the microcomputer 104 are the same and stored in the storage unit 102, the data stored under the control of the microcomputer 104 is output to the display unit 103 so that the user can view it. will be.

As described above, the device and method for receiving individual data according to the present invention, in particular, can secure the reception data, thereby expanding the service application range, and also enable the service of information for adding personal confidential information or royalties. It is effective.
