SOFTWARE UPDATING METHOD FOR DIGITAL TELEVISION RECEIVER USING RECORDED DATA

摘要

PROBLEM TO BE SOLVED: To update the programming of a digital TV receiver by preparing a process, where an extracted data program is transferred to a program memory area where the programming information is held to the digital TV receiver. SOLUTION: An MPEG-2 transport decoder 102 receives an MPEG-2 transport stream from a DTV8-VSB tuner 210 or an IEEE 1394 interface 110 via a multiplexer 101. Then the decoder 102 processes a bit stream for extracting a PES packet of the program that is selected out of a multiplex program transport stream. Furthermore, a decoded data transport packet is re-decoded to a selected data program and supplied to a memory device 212 which serves as a volatile or nonvolatile RAM.
