ABSTRACT:
Accelerated channel change (ACC) strategies are described for supplying a client module with media information by transitioning between a first delivery of media information provided by first delivery functionality and a second delivery of media information provided by second delivery functionality without exceeding prescribed data rate limitations. The first delivery functionality can represent server-based functionality for delivering a unicast stream of media information at a data rate (or maximum data rate) of some excess amount over the nominal rate of delivery, starting at a selected location within the media information. The second delivery functionality can represent any functionality for delivering the media information at the data rate (or maximum data rate) of the nominal rate of delivery. A join interval separates the first delivery at the excess rate and the second delivery at the nominal rate. In that period, the first delivery functionality can provide media information at a join interval data rate. The join interval data rate, if it is below the nominal data rate, will cause the client module to miss packets of media information. The client module can receive these missing packets by issuing retry requests to the first delivery functionality or to some other entity. The client module can determine the excess amount available by investigating the amount of missing information that occurs at different data rates; or the excess amount can be defined in advance.
