摘要： The invention relates to a method for encoding, a method for decoding, an apparatus, computer program products, an encoder and a decoder for video information. The motion vector for a block in a video image is predicted from a set of motion vector prediction candidates determined based on previously-coded motion vectors. A motion vector prediction candidate is included in the set based on the location of the block associated with the first spatial motion vector prediction candidate and in comparison with motion vector prediction candidates already in the set.

摘要： A method and apparatus are provided for encoding and decoding image information. The encoding comprises receiving a block of pixels; creating a set of motion vector prediction candidates for the block of pixels; and examining the set to determine if a motion vector prediction candidate is a temporal motion vector prediction, or a spatial motion vector prediction. If the motion vector prediction candidate is a temporal motion vector prediction, the motion vector prediction candidate is kept in the set. If the motion vector prediction candidate is a spatial motion vector prediction, it is examined whether the set comprises a motion vector prediction candidate corresponding with the spatial motion vector prediction; and if so, the motion vector prediction candidate is removed from the set. Once the set is created, one of the candidates from the set is selected to represent a motion vector prediction for the block of pixels.

摘要： Various methods, apparatuses and computer program products for video encoding and decoding are provided. In some embodiments, to indicate a composition of pictures of different time instants, some usability information may be embedded to the video bitstream indicating the intended display behavior when more than one layer is used and associated display behavior using this information. More specifically, the embedded information may indicate how the layers need to be composed in the video bitstream. The information may indicate if the intended display behavior is to combine (overlay) base layer and enhancement layer decoded pictures. The information may indicate that the base and enhancement layer decoded pictures are allowed to be overlaid. In addition or alternatively, the information may indicate that the enhancement layer picture should not be combined with base layer picture during display.
