摘要:
A subscriber distribution system for distributing broadcasting data to subscribers through a subscriber network. The subscriber distribution system has a PID filter section for checking contents of an inputted MPEG2 MPTS frame and splitting the MPEG2 MPTS frame into SPTS, a table regenerator for regenerating a PAT and a PMT that correspond with the SPTS by changing contents in the PAT and the PMT. An SPTS splitting and storing section stores the SPTS at high speed in a memory area of a buffer, which is assigned to subscribers according to PIDS. A subscriber distribution section selecting the SPTS requested by subscribers and storing the SPTS in the memory area of the buffer assigned to subscribers. A control section receives MPTS information from a higher network to provide MPTS information to the PID filter section and the table regenerator, and receives a request for a program from subscribers, and transfers the request to the subscriber distribution section.
