Abstract: A method of indicating bit stream subsets in a video bit stream (210) is provided. The method comprises receiving the bit stream, dividing the bit stream into video packets (211-216), wherein each packet comprises either one of video data or supplemental information, and marking each packet with a single subset identifier (stream_id). Each subset identifier is associated with a corresponding bit stream subset (221-223). Further, a method of extracting video packets from a video bit stream is provided. The method comprises providing relevant subset identifiers, receiving video packets from the bit stream, and, for each received packet, inspecting the subset identifier of the packet. The packet is extracted if the subset identifier matches one of the relevant subset identifiers. This allows condensing properties of a bit stream subset into a single identifier, thereby simplifying the processing of video packets in the network and on the client side. Further, devices corresponding to the aforementioned methods are provided.
