Abstract
Official abstract text for this publication.
A multimedia provider multicasts a main multimedia stream comprising a mixture of intra and inter frames and multicasts an associated auxiliary stream comprising intra frames. At least a portion of the intra frames in the auxiliary stream are generated based on same multimedia data as at least a portion of the inter frames of the main stream. The provider also transmits a stream information channel comprising information descriptive of time instances of intra frames in the main and auxiliary streams. This information allows a set top box to selectively connect, in connection with session set-up and channel switch, to the main or auxiliary stream to receive an intra frame with as a low delay as possible.
