Abstract:
1. A method for selecting transport streams and program channels to reduce delay in resolving digital video images while channel changing, comprising: receiving a channel signal spectrum including a plurality of digital video transport streams, each transport stream comprising a plurality of program channels; tuning a first digital video transport stream that includes a current program channel; selecting one or more additional digital video transport streams to tune based at least in part upon predictive channel selection and based at least in part upon which predicted program channels are multiplexed together in the transport streams such that the selected transport streams provide a desirable combination of multiplexed program channels with respect to the predicted program channels; tuning the one or more selected additional digital video transport streams; and utilizing a plurality of program channels within the first digital video transport stream and within the one or more additional digital video transport streams to help reduce delay time in channel-changing.
