Abstract: An Advanced Television Systems Committee Digital Television (ATSC DTV) transmitter transmits a digital multiplex that includes a legacy DTV channel and a mobile DTV channel. The mobile DTV channel is conveyed in mobile packets that comprise mobile data and additional mobile training information. A mobile packet comprises 207 bytes wherein 2 bytes are header information, 20 bytes are Reed-Solomon (RS) parity information and 185 bytes convey mobile data and mobile training information. The mobile training information is inserted into mobile packets such that the additional training information appears in contiguous positions after convolutional interleaving.

Abstract: An ATSC DTV mobile transmitter synchronizes their transmissions with other associated stations. An ATSC DTV mobile receiver hops across channels during periods of idle time for forming a program guide including program guide information from channels besides a selected channel.
