Abstract

Two additional structures for addition to the Digital Video Broadcasters (DVB) Service Information (SI) for implementation of the MPEG-2 Systems Standard (ISO/IEC 13818-1) are provided: the Logical Channel Table (LCT, 32) and the Composite Channel Table (CCT, 34). The LCT provides the mapping between a Logical Channel Number (LCN) representing a service and the transport stream (TSID)/program number (PN) on which the service can be found. LCT entries may designate either simple conventional channels or Composite Channels. The LCT contains a Composite Channel Indicator (CCI), which when set to '1', indicates that the selected channel is a composite channel. In this case, the LCT entry gives the home channel of the Composite Channel, which provides the CCT to the decoder so that the tuner (12) can be retuned to the actual program designated in the CCT for current viewing.
