Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] In digital TV, all information and signals, including video, audio, text, pictures, etc., are digitized and become data. Before transmission, the data must be packaged according to relevant standards (usually MPEG-2) to form fixed-length transport (TS) packets. MPEG-2 TS packets are 188 bytes long, and then quickly transmitted to the destination through the network. For these TS packets with the same length, if there is no guide information, the decoder at the receiving end cannot find the required code stream. Therefore, PSI is specifically defined in MPEG-2. The role of PSI is to automatically set up and guide the decoder to decode.

[0021] PSI consists of Program Association Table (PAT), Conditional Access Table (CAT), Program Mapping Table (PMT) and Network Information Table (NIT). Each table is divided into several segments and mapped (tr...
