Abstract:
The invention relates to concatenating or splicing of scalable video bitstreams. There are disclosed various methods, apparatuses and computer program products for video encoding and decoding and modifying coded video bitstreams. In some embodiments, indications are provided in the coded video bitstream to indicate a layer-wise decoding start-up process. These indications may be generated by encoders or splicers.

Claim (Index 26):
The method according to  claim 18  wherein the first array variable is LayerinitialisedFlag and the second array variable is FirstPiclnLayerDecodedFlag and index i identifies the scalability layer and wherein the method further comprises the following:\n when the layer-wise start-up is initiated, setting FirstPiclnLayerDecoded equal to 0 and LayerlnitialisedFlag equal to 0 for all scalability layers other than the scalability layer with index i equal to 0; \n when FirstPiclnLayerDecoded is equal to 0, generating unavailable pictures for the reference pictures of the first picture in decoding order in an enhancement layer with index i; \n setting LayerinitialisedFlag equal to 1, when an intra random access point picture in an enhancement layer with index i is decoded and LayerinitialisedFlag is equal to 1 for all values of j indicating reference layers of the enhancement layer with index i; and \n omitting an output of random access skipped leading pictures associated with the intra random access point picture in the enhancement layer for which LayerinitialisedFlag was set equal to 1.
