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 16):
The method according to  claim 9  wherein the layer-wise start-up further comprises one or more of the following:\n generating unavailable pictures for the reference pictures of the first picture in decoding order in the enhancement layer; \n omitting decoding of a coded picture in the enhancement layer preceding an intra random access point picture in the enhancement layer; \n starting an output of pictures of the enhancement layer from an intra random access point picture in the enhancement layer when correct decoding of all reference layers of the enhancement layer has been initialized; or \n omitting the output of random access skipped leading pictures associated with the intra random access point picture in the enhancement layer.
