    摘要: Encoded pictures comprise one or more independently decodable frames, reference frames, and predicted frames. In the method an arrangement step is performed for arranging the pictures in an encoding order, and information on the presentation order is defined for the encoded pictures. Further in the method, a transmission step is performed for transmitting said encoded pictures to a decoder, a decoding step for decoding the encoded pictures for forming decoded pictures, and rearranging step for arranging the decoded pictures in presentation order. An expected increment value of the presentation order per picture is defined, and a parameter indicative of the difference between the expected increment value and the real increment value is calculated. The calculated parameter is VLC coded, and the VLC coded parameter is transmitted, wherein the VLC coded parameter is used in the decoder for arranging the decoded pictures in correct presentation order.

    摘要: An explicit signaling element for controlling decoded picture output and applications when picture output is not desired. A signal element, such as a syntax element in a coded video bitstream, is used to indicate (1) whether a certain decoded picture is output; (2) whether a certain set of pictures are output, wherein the set of pictures may be explicitly signaled or implicitly derived; or (3) whether a certain portion of a picture is output. The signal element may be a part of the coded picture or access unit that it is associated with, or it may reside in a separate syntax structure from the coded picture or access unit, such as a sequence parameter set. The signal element can be used both by an encoder and a decoder in a video coding system, as well as a processing unit that produces a subset of a bitstream as output.

    摘要: A system and method for improving both coding efficiency and decoding accuracy in scalable video coding involving discardable lower layer adaptations, where applications can omit transmission of unused data for inter-layer prediction for all layers below an operation point of receivers. Indicator flags are utilized to avoid transmitting syntax elements that must be set to fixed values. In addition, padding algorithms or additional encoding constraints are applied to the encoding process.

    摘要: A system and method for conveying supplemental enhancement information related to different pictures in one access unit. Different pictures in one access unit may be pictures of each layer of a scalable video, pictures of each view of a multiview video, or pictures of each description in a multiple description coding (MDC) video. An indication is included in the coded bitstream indicating the pictures with which the supplemental enhancement information message is associated. During a subsequent decoding process, the device performing the decoding recognizes this information and uses it appropriately.

    摘要: In a method of encoding/decoding a video sequence, which is composed of video frames, a first video frame and a second video frame are divided into a set of coding blocks, and at least one of the coding blocks of the first video frame is encoded by intra-coding. Then a first reliable region in the first video frame that comprises at least one intra-coded coding block and a second reliable region in the second video frame are determined. At least one coding block of the second reliable region is predicted from said first reliable region, and said second reliable region in said video sequence is encoded such that an inter-prediction information dependency on coding blocks outside said first reliable region is prevented.

    摘要: An error concealment in decoding of inter-coded information, comprising normative error concealment within a decoding loop and proprietary error concealment outside the decoding loop. The normative error concealment provides meta-data and a reconstructed frame for the proprietary error concealment. Using these, the proprietary error concealment further enhances the reconstructed frame without effecting on the decoding of the inter-coded data. A mobile station, network element and a computer program product using the method have further been described.

    摘要: A method for encoding a video sequence comprising an independent sequence of image frames, wherein at least one reference image frame is predictable from at least one previous image frame that is earlier than the previous reference image frame in decoding order. An indication of at least one image frame is encoded into the video sequence, which indicated image frame is the first image frame, in decoding order, of the independent sequence, said at least one reference image frame being included in the sequence. In the decoding phase, the indication of at least one image frame is decoded from the video sequence, and the decoding of the video sequence is started from said first image frame of the independent sequence, whereby the video sequence is decoded without prediction from any image frame decoded prior to said first image frame.
