Abstract

본 발명은 위성방송이나 케이블방송과 같은 멀티 채널시스템에서 각 채널의 방송내용을 통합하여 가이드해줄 수 있는 서비스 프로그램 가이드 시스템에 관한 것으로, 본 발명은 종래PIP를 이용한 서비스프로그램 검색시 동일기능을 행하는 블럭이 2개씩 필요하므로 시스템이 복잡해지고 코스트가 상승하며, 각각의 서비스 프로그램을 각각의 채널로 방송하므로 만약 시청자가 채널검색을 통해 시청하고자 하는 방송을 검색하기 위해선 반드시 모든 서비스 프로그램을 검색하여야 하는 번거로움이 있었던 점을 감안하여 각 방송국에서 보내는 서비스 프로그램을 받아 이를 한 화면내에서 각각의 서브화면으로 재구성한 후 이를 다시 코딩하여 서비스 프로그램 가이드(SPG)채널로 전송함으로써 시청자가 SPG채널에 의해 각 채널의 서비스 프로그램 정보를 쉽게 알 수 있도록 한 것이다.The present invention relates to a service program guide system capable of integrating and guiding broadcast contents of each channel in a multi-channel system such as satellite broadcasting or cable broadcasting. The present invention provides a block for performing the same function when searching for a service program using a conventional PIP. Since these two are required, the system is complicated, the cost is increased, and each service program is broadcasted to each channel, so if a viewer wants to search for a broadcast that they want to watch through channel search, it is necessary to search all the service programs. In consideration of the fact that there was a service program received from each broadcasting station, it is reconstructed into each sub-screen in one screen, and then recoded and transmitted to the service program guide (SPG) channel. Service program information I would have let you know.

Claims

A plurality of decoders for receiving and decoding service programs of each broadcasting station transmitted through a satellite, a plurality of decimators for dimning the output of the decoder into sub-screens, and synchronizing programs of each broadcasting station through the decimator A channel synchronization adjusting unit configured to convert the sub-screens through the channel synchronization adjusting unit into one screen and output information on each sub-screen, and encode a signal for sub-screen configuration among the outputs of the sub-screen integration unit. And an encoder, a demultiplexer for integrating the output of the encoder and information on each subscreen from the sub-screen integrator, and a modulator for modulating the output of the de-multiplexer.

The service program guide system of claim 1, wherein the sub-screen integrator inserts and outputs an automatic channel change descriptor for matching PID values of each sub-screen into an EIT service stream.
