An Advanced Television Systems Committee Digital Television (ATSC DTV) mobile, or handheld, device comprises a receiver for receiving a signal that includes a mobile DTV channel, which is transmitted in StaggerCast form comprising an FEC (Forward Error Correcting) stream and an encoded stream delayed in time from the FEC stream for conveying program content. The receiver decodes the received encoded stream for providing the program content and, if errors are detected in the received encoded stream, uses the received FEC stream to attempt to correct the errors. However, when the uses changes programs, or channels, to a different StaggerCast stream, the receiver decodes a received encoded stream of the different StaggerCast stream for providing the new program content even though for an initial period of time error correction by the receiver is severely limited. |
