METHOD FOR TRANSMITTING/RECEIVING INTERACTIVE SATELLITE EDUCATION PROGRAM INFORMATION USING DESCRIPTOR

摘要

1. the art that the invention defined in the claims; The invention, will on the interactive satellite distance education program information transmission / reception method using the descriptor.; 2. The invention attempts to solve the technical challenges; The present invention, after defining the information needed for interactive satellite distance learning services by transmitting by inserting a descriptor form the cyclic (Event Information Table) EIT transmitted, additional interactive satellite distance education service information generator, the periodic transfer unit, and that aims to provide an interactive satellite distance education program information transmission / reception method using, descriptors to reduce the processing content according to a receiver.; 3. Resolution of the subject matter of the invention,; The invention, of teaching lessons screen, Lecture of multicast data, the program showing a channel information-specific information / service information (PSI / SI) tables and Steel add data to an interactive satellite using, descriptor for transmission via satellite a remote education program information transmitting method, interactive comprising: a first step of generating a descriptor indicating that the satellite distance learning services; A second step of inserting the generated descriptor in the program specific information / service information (PSI / SI) tables; And including a third step of transmitting the program specific information / service information (PSI / SI) tables inserted to the receiving terminal via a satellite descriptor.; 4. An important use of the invention,; The present invention used to fight like interactive satellite distance education system.
