摘要： In one aspect, a compressed video bit stream is received and divided into packets that comprise either video data or supplemental information. Each packet is marked with a first subset identifier associated with a corresponding bit stream subset. A first sequence parameter set (SPS) is marked with the same first subset identifier as its associated bit stream subset. The first SPS comprises a second subset identifier indicating a decoding dependency of the bit stream subset associated with the first subset identifier on a bit stream subset associated with the second subset identifier. In another aspect, the packets from the bit stream are received and the first SPS is extracted. The first and second subset identifiers are used as relevant subset identifiers, and for each received packet, the first subset identifier is inspected and the packet is extracted when the first subset identifier matches one of the relevant subset identifiers.

摘要： An auxiliary information map (10) is upsampled to form an upsampled auxiliary information map (20). Multiple reference pixels (23) in the upsampled auxiliary information map (20) are selected for a current pixel (21) in the upsampled auxiliary information map (20) based on texel values of texels in an associated texture (30). An updated pixel value is calculated for the current pixel (21) based on the pixel values of the selected reference pixels (23).

摘要： A technique for distributing in a multicasting network media content via two or more media layers is described. The media layers are hierarchically arranged in accordance with a scalable coding protocol such as the Scalable Video Coding (SVC) protocol. In a method implementation of this technique, in a first step a first number of media recipients for a first media layer that is transmitted via a first bearer of the multicasting network is determined. Then, a second bearer of the multicasting network for at least one second media layer is selected taking into account the first number and a hierarchical relationship between the first media layer and the second media layer.

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： A technique for encoding and decoding data pertaining to multiple video views is presented. 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. On the basis of the encoded picture of the first picture stream and encoded picture of the second picture stream, dedicated video streams are generated.
