摘要： There are provided video encoders and corresponding methods for encoding video data for an image that is divisible into macroblocks. A video encoder includes an encoder (400) for performing intra mode selection when encoding a current macroblock by testing a first subset of intra modes to compute a rate distortion cost, and utilizing the rate distortion cost to determine whether to terminate the intra mode selection and which additional intra modes, if any, are to be examined with respect to the current macroblock. The best inter mode may also be used to perform intra prediction.

摘要： There is provided a compression method for handling local brightness variation in video. The compression method estimates the weights from previously encoded and reconstructed neighboring pixels of the current block in the source picture and their corresponding motion predicted (or collocated) pixels in the reference pictures. Since the information is available in both the encoder and decoder for deriving these weights, no additional bits are required to be transmitted.

摘要： There are provided methods and apparatus for measuring a received quality of at least one of a video multicast and a video broadcast for a plurality of users. A method includes receiving (225) data from the plurality of users regarding the received quality, and increasing (235) a weight of the data for any of the plurality of users having the received quality greater than a threshold.

摘要： There are provided methods and apparatus for film grain SEI message insertion for bit-accurate simulation in a video system. A method for simulating film grain in an ordered sequence includes the steps of providing film grain supplemental information corresponding to a plurality of intra coded pictures, and providing additional film grain supplemental information corresponding to inter coded pictures between consecutive intra coded pictures, in decode order. The inter coded pictures are selected based upon display order.

摘要： A Digital Video Broadcasting-Handheld (DVB-H) system comprises a head-end and at least one receiver. The head-end uses the File Delivery over Unidirectional Transport (FLUTE) protocol for transmitting an electronic service guide (ESG) and content to the receiver. The receiver determines a time delay for receiving content as a function of a value of a PublishedStartTime parameter from the ESG and the actual time the receiver receives the content. Using this time delay, the receiver forms a time estimate for receiving selected content as a function of a value of a PublishedStartTime parameter from the ESG for the selected content and the determined time delay. The receiver then performs power, management such that during those intervals of time that the receiver is not expected to receive the selected content the receiver can reduce power.
