摘要： A Video-on-Demand Server architecture transmits a plurality of pre-coded programs having different bit rates across a fixed bandwidth channel. For each program, a generator generates a plurality of different bit rate representations for each program. Each generator also provides control information at each of a plurality of successive time windows T for each bit rate representation. The control information provides a bit rate and a quality measure during each time window T. The control information enables a statistical multiplexer to select a bit rate representation for each program during each time window T to maximize the quality of the selected representations while not exceeding the total available channel capacity.

摘要： Various implementations for reducing artifacts such as, for example, I-frame flicker are proposed. Particular implementations produce a no-flicker reference in which a picture intended to be coded as an I-frame is, first, coded as a P-frame using a reference picture from the previous GOP. Thus, continuity with the previous GOP is provided. According to a general aspect, a source image is inter-coded to produce coded source data. The coded source data is decoded to produce a modified source. The modified source is intra-coded to produce coded modified-source data. The coded modified-source data is decoded to produce a reference image.
摘要翻译：提出了用于减少伪像的各种实现方式，例如I帧闪烁。特定实施方式产生无闪烁参考，其中要被编码为I帧的图像首先使用来自先前GOP的参考图像被编码为P帧。因此，提供了与先前GOP的连续性。根据一般方面，源图像被帧间编码以产生编码源数据。编码的源数据被解码以产生修改的源。经修改的源被帧内编码以产生编码的修改源数据。编码的修改源数据被解码以产生参考图像。

摘要： A scheduler schedules multimedia content files for transmission over a broadcast network. Multimedia content files can be any sort of audio/video clips like, sports video, music video, news clip, movie sound track etc. In particular, the scheduler determines a transmission order for content files as a function of a dynamic priority value, which is determined in accordance with at least a dissimilarity measure between the content files; wherein the dissimilarity measure of the media content files is further determined as a function of the clip meta data associated with each clip. Schedule timing information and meta data information is transmitted over a broadcast network along with the clips so that receivers can do selective reception of their preferred clips, saving battery power and storage.

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.
