The video encoder 125 converts the selected digital broadcast video signal provided by the MPEG decoder 120 to an NTSC or PAL analog video signal and then provides the image synthesizer 150.

Meanwhile, the modem 130 transmits data between the service provider and the mutual data through the switching line. For example, when a user watches a pay program, the microcomputer 110 receives user information registered in the smart card 135. The billing processing for the corresponding program is performed by transmitting to the service provider, and when the message transmission to the other satellite broadcasting receiver according to the present invention is required, the user-selected message is transmitted to the other satellite broadcasting receiver by using a switching line. Done.

The memory unit 140 includes various menu screen information for controlling the overall operation of the satellite broadcasting receiver, various message data for message transmission of the satellite broadcasting receiver according to the present invention, ID information for a plurality of users, and IDs for each user. A corresponding telephone number is received from a user and stored in a predetermined area.

The OSD unit 145 restores the encoded various OSD data provided from the above-described tuner and demodulator 115 to the original signal before encoding, and configures it as an OSD screen to provide the image synthesizer 150, in particular, a memory. Various menu screen information and message data stored in the unit 140 are received from the microcomputer 110 to be configured as a menu screen of a predetermined form, and then provided to the image synthesizer 150.

Accordingly, the image synthesizing unit 150 transfers the analog satellite broadcasting signal output from the video encoder 125 to the display side, not shown, or omits the screen mixed with various menu screen data displayed through the OSD unit 145. To the display side.

In the satellite broadcasting receiver configured as described above, when the user operates the key input unit 105 to input a message transmission key signal to transmit a predetermined type of message to another satellite broadcasting receiver user, the microcomputer 110 may store the memory unit ( Menu screen information and message data stored in 140 are read and provided to the OSD unit 145.

In addition, the OSD unit 145 configures the input menu screen information and the message data as a message transmission menu screen as shown in FIG. 2, and displays the menu screen information and the message data on the monitor not shown through the image synthesizing unit 150.

Accordingly, the user first inputs a receiver ID for receiving a message and then selects one message among a plurality of preset types of messages by referring to the message transmission menu screen shown in FIG. 2. 110 detects whether the input receiver ID is included in a plurality of other satellite broadcast receiver user information previously stored in the memory unit 140.

That is, the predetermined area of the memory unit 140 stores the ID and phone number of another satellite broadcasting receiver user input by the user, and the microcomputer 110 determines whether the receiver ID entered by the user is an error based on this. Will be checked.

If the receiver ID input by the user is not included in the receiver information pre-stored in the memory unit 140, the microcomputer 110 displays a predetermined guide message indicating that the corresponding ID does not exist through the OSD unit 145. (For example, the 'ID entered does not exist').

On the contrary, if the ID input by the user exists in the memory unit 140, the phone number for the corresponding ID is read and connected to the counterpart receiver through the modem 130 to transmit the message selected by the user.

Eventually, the message transmission method allows the user to send a predetermined message to another satellite broadcast receiver user. Examples of such a message include a birthday message, a specific channel recommendation, and a call request. Will be.

3 is a flowchart illustrating a message transmission process of a satellite broadcast receiver according to a preferred embodiment of the present invention. A series of processes described above with reference to the accompanying drawings will be described in detail as follows.

During operation of the satellite broadcasting receiver during the normal viewing mode for receiving and displaying the broadcast signal of the specific channel selected by the user or during the standby mode for performing any command input through the key input unit 105 (step 301). When a key signal is input (step 303), the microcomputer 110 drives the OSD unit 145 to display a message transmission menu screen as shown in FIG. 2 (step 305).

If the message transmission menu screen is displayed through such a process, if a key signal for canceling message transmission is input or a receiver ID and a message to be transmitted are not selected for a predetermined time (step 309), the microcomputer 110 Blocks the operation of the OSD unit 145 to automatically turn off the message transmission menu screen displayed on the current screen (step 327).

On the contrary, when the user selects the receiver ID and the message to be transmitted through the key input unit 105 while the message transmission menu screen is displayed through the above-described step 305 (step 307), the microcomputer 110 stores the memory unit. A plurality of receiver information stored in a predetermined area of 140, i.e., information about a plurality of other satellite broadcast receiver users are read (step 311) to detect whether there is a receiver ID input in step 307 described above (step 313).

In this case, when the user ID of the user input does not exist in the memory unit 140, a guide message indicating that the input ID does not exist (for example, 'the input ID does not exist') is displayed for a predetermined time. After that (step 315), the message transmission menu screen is displayed again.

If the receiver ID input by the user exists as a result of the detection in step 313 described above, the microcomputer 110 drives the modem (step 317) and dials the telephone number corresponding to the receiver ID to receive the corresponding user (receiver). Attempt to connect to the satellite broadcast receiver of ID) (step 319), in which case the modem connection is not established when the modem of the other receiver is not in use or the connection is not made due to the power off of the other receiver. After displaying the guidance message (for example, 'unable to connect with the other party') for a predetermined time, the operation of the modem 130 is stopped (step 325).

Then, the message transmission menu screen displayed on the current screen is turned off, and the overall operation of the satellite broadcasting receiver is switched to the normal viewing mode such as the initial stage 327 described above (step 327).

On the contrary, if a connection is made with the other party's satellite broadcast receiver through the modem 130 in step 319, the microcomputer 110 may select the message and the smart card 135 selected by the user in step 307. The user information (caller ID) registered in S is transmitted to the satellite broadcast receiver of the other party through the telephone line (step 323).

When the message transmission is completed, the modem 130 and the OSD unit 145 are disconnected to release the connection with the other party's satellite broadcast receiver (step 325), and then the menu screen is turned off, thereby the satellite broadcast receiver may be turned off. The overall operation is switched to the normal viewing mode of the initial step 301 described above (step 327).

In addition, the satellite broadcast receiver of the other party receiving the message transmitted through the above process displays and displays the transmitted message and the caller information on an OSD screen, thereby transmitting the messages between the receivers.

As described above, according to the present invention, by using a modem mounted inside the satellite broadcasting receiver, direct message transmission between each use is possible, and thus, there is an effect of satisfying the needs of various users.
