digital receiver and managing method of inactive channel in Digital receiver

摘要

PURPOSE: An inactive channel process method of a digital receiver for supplying a GUI and a scenario to a user about an active channel is provided to select a desired channel through the active channel list by displaying an active channel list. CONSTITUTION: If the tuning of a selected channel operates, a base PID(Packet Identifier) is set in a de-multiplexer(S50, S70). The de-multiplexed VCT(Virtual Channel Table) transmitted to a PSI(Program Specific Information) and a PSIP(Program and System Information Protocol)(S80). The PSI and the PSIP decoder generated PSI and PSIP DB by the decoding of VCT(S90). In case the selector channel is the inactive channel, A/V PID of the channel information is set as null(S110). The channel information is transmitted to the de-multiplexer. The channel map update operates.
