Nowadays, televisions which are capable of receiving video / audio playback of a corresponding broadcast program by receiving a television broadcast signal wirelessly transmitted from a plurality of television stations through a reception antenna and tuning a desired channel are generally used. Cable TV (CATV) has been adopted to allow subscribers to watch broadcast programs in advance, and to make non-contractors scramble (Scramble) so that they cannot watch the broadcast.

According to such cable television broadcasting, up to 64 channels of broadcasting programs such as movies, music, sports, news, educational programs, etc., from wired cable television broadcasts transmitted through wired cables and communication satellites (CS) through satellite parabolic antennas are provided. It is classified as satellite broadcast that is received by being descrambled by a decoder installed on the television side. Since the broadcast channel assigned to such a broadcast program is transmitted in a broadcast signal of GHz, dozens of broadcast channels are allocated. When the channel number (for example, 120 channel number of 120) allocated for the cable broadcasting program is set by the user's key operation and the predetermined channel is selected and the predetermined channel is selected, the corresponding channel is tuned through the signal processing system. Signal processing allows video / audio playback.

On the other hand, satellite broadcasting televisions receiving such satellite broadcasting can select channels for up to 64 satellite broadcasting channels, so that it is not possible to easily determine whether a broadcast program of a desired broadcasting channel is broadcast. There is a disadvantage in that it takes time to find a broadcast channel having a time zone in which a broadcast program is organized, as the channel switching operation must be repeatedly performed on a channel that has not yet been made.

Accordingly, the present invention has been made in view of the above circumstances, and it is determined whether a broadcast channel is tuned to a tuned channel based on program programming data received through KBPS data for a plurality of satellite broadcast channels, respectively. An object of the present invention is to provide a broadcasting channel line international language method for satellite broadcasting television, which can skip channels for which no broadcasting is performed.

And a second step of determining whether a program of a corresponding broadcast channel is currently broadcasted through program programming data of the selected broadcast channel when selecting a channel for a predetermined satellite broadcasting channel, and selected through the program programming data. Skips a channel to another adjacent channel if it is determined that a broadcast program of the broadcast channel is not currently broadcast; and selects and reproduces the corresponding satellite broadcast channel if it is determined that the skipped broadcast channel is broadcast through the program configuration data. The international language method of the broadcasting channel of the three-stage satellite broadcasting television The ball.

According to the present invention configured as described above, when a predetermined channel is selected by a key operation of a viewer in a satellite broadcasting television that selectively tunes and reproduces a plurality of satellite broadcasting channels, a program extracted from the KBPS data of the plurality of channels, respectively. If the selected broadcast channel is broadcasted based on the organized data, and if the broadcast time has elapsed and no broadcast is made, the channel is skipped to an adjacent broadcast channel so that channel selection and playback can be performed only for the broadcast channel. .
