摘要： The present invention provides a method and apparatus for facilitating processing of images contained in an encoded video stream. In one embodiment of the present invention, a plurality of non-intra coded images are transcoded into intra-coded images (I-images). The transcoded I-images are then used to facilitate trick mode playback, such as reverse playback, fast reverse playback or fast forward playback. In addition, an image sequence window is defined and transcoded I-images which fall outside of the image sequence window are deleted from a memory.

摘要： A method is claimed for encoding a group of pictures at a target bit rate. A pre-analysis procedure (105) is performed for each frame in the group of pictures as to develop a series of parameters. A pre-processing procedure is then performed for a frame selected from said group of pictures (115), so that the parameters associated with the selected frame are updated while the parameters associated unencoded frames from the group of pictures remain the same. These two sets of parameters are then used to determine an allocated bit rate (125) for the frame such that when the frame is actually encoded, the allocated bit rate is reserved for the encoding operation. The allocated bit rate and the target bit rate for the group of pictures may be different, and the quantization level associated with the allocated bit rate may be different than the quantization level associated with the actual bit rate used to encode the frame.

A scalable video encoder includes an encoder (100) for encoding a block in an enhancement layer of a picture by applying a weighting parameter to an enhancement layer reference picture. The weighting parameter used to encode the block in the enhancement layer is adaptively selected from between a weighting parameter applied to a lower layer reference picture to encode a block in the lower layer of the picture and a different weighting parameter applicable in the enhancement layer. The block in the enhancement layer corresponds to the block in the lower layer. The enhancement layer reference picture corresponds to the lower layer reference picture.
