Data Broadcasting Transmission System

摘要

One of the features of digital broadcasting is data broadcasting services. Digital terrestrial broadcasting services began in Japan in December 2003, requiring a new broadcasting method differing from that existing for broadcast satellite/communications satellite (BS/110 deg CS) digital services. For terrestrial broadcasting services, the TV network is formed by network stations. One station receives a program and distributes it to other stations while retransmitting it to the area of its own coverage. In the case of data broadcasting services, it is considered that the transport stream (TS) method will be used to transmit programs from the sending station to the receiving stations in the TV network. Toshiba has developed a new data broadcasting system, the TS converter, to realize TS format distribution. The TS converter has "TS through," "elementary stream (ES) filtering," and "module exchange" functions. We expect application of the TS converter to expand for digitization of broadcast stations in the future.
