                Digital TV Q&A

                Q£ºHow come one Set Top Box (STB) can provide so many programs?

                A:In digital TV signals, one stream can transmit multiple programs through multiplexing. Once a certain program is chosen, the program package will be drawn from the stream, then decoded and played.

                The STB is like a company¡¯s dormitory. Each program is like an employee in the dorm. To find one employee, you have to first find the archive that records the dorm information, then find out the employee¡¯s dorm number according to the employee¡¯s personal information, then go to that dorm to find him/her.

                Q:How does the STB differentiate each program?

                A:The STB can differentiate programs by their PSI/SI information. PSI describes the information each stream carries, including the description of the basic stream that forms each program and the program itself.

                SI describes the technological features of each service provided by one player and some other information, such as the type ofprogram, service provider, and the relationship between each program. Users can choose services or events in the stream, and the STB will automatically allocate and receive the information.

                Every program is like an employee in a dorm. You can locate an employee by his/her personal and additional information.

                Personal information: Gender, appearance, height, etc.

                Additional information: Name, department, work number, etc.

                PS: These two Q&As provide a general idea of digital TV and don¡¯t include all the details.
