Abstract:
1. A digital television (DTV) signal converter, comprising: a satellite band receiver that receives satellite television broadcast data from a satellite service and demodulates the satellite television broadcast data into a digital data stream; wherein the digital data stream contains television content, satellite television logical channel identification information and electronic program guide data, and wherein the television content, the satellite television logical channel identification information and the electronic program guide data are associated with a set of satellite television logical channels provided on the satellite service; a channel mapper that maps the satellite television logical channel identification information in the digital data stream to DTV channel identification information; a packet reformatter that determines, based upon the mapping of the satellite television logical channel identification information to the DTV channel identification information, whether each satellite television logical channel will fit within one DTV transport stream; for each satellite television logical channel within the set of satellite television logical channels, if the satellite television logical channel will fit within one DTV transport stream, then the packet reformatter assigns the satellite television logical channel to a single DTV transport stream, and if the satellite television logical channel will not fit within one DTV transport stream, then the packet reformatter splits the satellite television logical channel among multiple DTV transport streams; and a remodulator that modulates the DTV channel identification information, the television content and the electronic program guide data for transmission as an output comprising the one or more DTV transport streams to the at least one digital television.
