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 prediction weight is calculated based on depth clipping plane parameter values associated with the frame (10) and with a reference frame (20, 30) based on which pixels of the frame (10) are encoded and decoded. Using depth clipping plane parameter values when calculating prediction weights, improves coding efficiency of depth map coding and decoding.

摘要： An encoder and a method therein for providing an update message relating to at least one of camera parameters and depth parameters “the parameters”, a decoder and a method therein for decoding the update message, a first device including the encoder and a second device including the decoder are provided. The parameters enable the decoder to synthesize a first view for a first camera position based on a second view for a second camera position and the parameters of the second view. The encoder detects which of the parameters are changing over time. Next, the encoder modularizes the parameters into a respective module. Furthermore, the encoder encodes each respective module into the update message and sends the update message to the decoder. Next, the decoder decodes each respective module of the update message to obtain the parameters which are to be updated.

摘要： Supplemental processing information (52, 54) defining post-decoding instructions for processing decoded media content is co-organized in a file (1) together with a pseudo-identifier of a media codec employed for encoding the media content. The co-organization trigger abortion of decoding of the media content by a legacy media terminal (210) that does not recognize the pseudo-identifier but enables decoding of the media content by a media terminal (200) that recognizes the pseudo-identifier to thereby enable post-decoding processing of the decoded media content using the supplemental processing information (52, 54). The co-organization thereby prevents legacy media terminals (210) that cannot use the supplemental processing information from decoding the media content and rendering the media content in a media presentation.

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.

At least one candidate motion vector predictor (44, 54) is provided for a current motion vector (34) to be encoded. A motion vector predictor (44) is then determined from the at least one candidate motion vector predictor (44, 54). Correspondingly, during decoding a motion vector (34) is determined for a current pixel block (30) based on a motion vector predictor (44) determined for the current pixel block (30).
