    摘要： A reference picture marking process and a reference picture list management process is handled in a unified reference picture marking and reference picture list management process. A new idle reference picture list may be used for handling reference pictures that are not used for reference in the current picture. Differential coding of picture order count may be used to increase coding efficiency. The reference picture management syntax structure may be sent in the picture parameter set for improved coding efficiency e.g. in regular GOP (group of pictures) arrangements.

    摘要： A video image decoding device (1) is equipped with a TT information decoder (14) that, in the case where encoded data includes merge/skip information that merges or skips presence information indicating whether or not frequency-domain transform coefficients are included in the quantized transform coefficients, does not decode the presence information, and a TT information inference unit (33) that, in the case where the encoded data includes merge/skip information that merges or skips the presence information, infers the presence information. The TT information decoder (14) uses presence information inferred by the TT information inference unit (33) to decode the encoded and quantized transform coefficients.

    摘要： Methods and devices for encoding and decoding scalable video are described. In one aspect, a method of reconstructing, in a video decoder, an enhancement-layer image based upon a reconstructed reference-layer image using inter-layer prediction is described. The method includes reconstructing a reference-layer residual and a reference-layer prediction, wherein the reference-layer residual and the reference-layer prediction, when combined, form the reconstructed reference-layer image; up-sampling the reference-layer residual using a first up-sampling operation; up-sampling the reference-layer prediction using a second up-sampling operation different from the first up-sampling operation; generating an inter-layer prediction using the up-sampled reference-layer residual and the up-sampled reference-layer prediction; and reconstructing the enhancement-layer image based upon the inter-layer prediction.
