摘要： 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.

A method embodiment of the encoding technique comprises the steps of providing first picture stream belonging to a first view and performing a first encoding operation to encode a picture of the first picture stream. The first encoding operation is based on a single-view video codec and provides encoder state information relevant for the encoding of another picture of the first picture stream. Also provided is a second picture stream belonging to a second video view. A second encoding operation is performed to encode a picture of the second picture stream based on the single-view video codec, wherein the second encoding operation is based on the encoder state information provided by the first encoding operation.

摘要： A method of indicating bit stream subsets in a compressed video bit stream is provided. The method comprises receiving the bit stream, dividing the bit stream into packets, wherein each packet comprises either one of video data or supplemental information, marking each packet (310–312, 320–322) with a first subset identifier (s0, s1) which is associated with a corresponding bit stream subset, and providing a first sequence parameter set (SPS) (310), marked with the same first subset identifier as its associated bit stream subset. The first SPS further comprises a second subset identifier (b1) indicating a decoding dependency (304) of the bit stream subset associated with the first subset identifier on a bit stream subset associated with the second subset identifier. Further, a method of extracting video packets from a video bit stream is provided. The method comprises receiving packets from the bit stream, extracting a first SPS (310), which is marked with the first subset identifier (s0) and further comprising the second subset identifier (b1), using the first and the second subset identifier as relevant subset identifiers, and, for each received packet (310–312, 320– 322), inspecting the first subset identifier (s0, s1) of the packet, and extracting, under the condition that the extracted first subset identifier matches one of the relevant subset identifiers, the packet from the bit stream.

摘要： The embodiments use prediction weights in connection with predictive encoding and decoding of a depth map in the form of a frame (10) with pixels (11) having pixel values representing distances between a camera (40) and objects.

The encoder (310) detects which of the parameters are changing over time. Next, the encoder (310) modularizes the parameters into a respective module. Furthermore, the encoder (310) encodes each respective module into the update message and sends the update message to the decoder (320). Next, the decoder (320) decodes each respective module of the update message to obtain the parameters which are to be updated.
