Abstract
Disclosed is a system decoder of a digital TV. Particularly, the system decoder brings about the effect of remultiplexing packet data input from different channels by giving an ID to each channel, using it as an extension field of a packet ID (PID) and an extension field of a table ID of a section that are defined in the ISO/IEC 13818-1, and storing the channel ID information in the buffer transmitting packets and outputting them. Further, a memory allocated to each component can be operated without channel discrimination through the extension fields and the remultiplexing effect. Moreover, it is possible to minimize the time and cost taken to modify hardware and software so as to apply a PID filter or the like designed in a single channel to a decoder ASIC supporting a plurality of channels.
