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 5):
An apparatus comprising at least one processor and at least one memory, said at least one memory stored with code thereon, which when executed by said at least one processor, causes an apparatus to perform at least the following:\n receive or obtain a bitstream including coded pictures in two or more scalability layers; identify a first coded picture within the bitstream, the first coded picture having a picture type that may be used to start decoding; conclude that a layer-wise start-up is initiated with the first coded picture on a basis of an indication received in or along the bitstream of an association of the first coded picture with the layer-wise start-up, wherein the layer-wise start-up comprises: controlling the layer-wise startup by a first array variable, wherein each scalability layer of index i is associated with an entry in the first array variable indicative of whether correct decoding of the scalability layer corresponding to the entry in the first array variable has been initialized; and controlling the layer-wise startup by a second array variable, wherein each scalability layer of index i is associated with an entry in the second array variable indicative of whether a picture in the scalability layer corresponding to the entry in the second array variable has been decoded but may have been decoded incorrectly; and cause one or more decoded pictures to be output.
