Abstract: In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

Abstract: This disclosure describes techniques for resizing multimedia content for efficient statistical multiplexing. In response to a request to resize a current segment of data, an encoding module associated with the selected segment adjusts the amount of motion information to be encoded to resize the segment of data. For example, the encoding module associated with the selected segment of data may merge two or more motion vectors to reduce the amount of motion information to be encoded. As another example, the encoding module reselects encoding modes for one or more blocks of pixels of at least one frame within the segment of data.

Abstract: Methods and apparatus to process multimedia data enabling faster channel acquisitions, improved error recovery and improved efficiency. An encoder device encodes a first portion of multimedia data using inter-coding to generate a first version, and encodes the first portion of multimedia data using intra-coding to generate a second version. A decoder device receives a first version of a first portion of multimedia data, wherein the first version is inter-coded, receives a second version of the first portion of multimedia data, wherein the second version is intra-coded, and selectively decodes the first and second received versions.

Abstract: Quantization techniques are used in video coding to quantize residual coefficients. So-called "dead zone parameters" are selected in the quantization process of residual coefficients of residual video blocks. The dead zone refers to a region of magnitude for coefficients below which any coefficient will be quantized to zero. A method and apparatus of quantizing coefficient values of video blocks in a video coding scheme is provided. A quantization parameter is selected for a set of video blocks. Dead zone parameters are then selected for different video blocks in the set of video blocks. Next, the quantization parameter and the dead zone parameters are applied to quantize the coefficient values of each of the video blocks.

Abstract: Techniques for video encoding and decoding a common guide media logic channel (MLC) to enable fast acquisition and re/synchronization of the video stream while preserving compression efficiency are provided. Systems and methods to process multimedia data using channel switch frames are presented. The system comprises an encoder operative to generate a common guide media logical channel (MLC) of a plurality of channel switch frames (CSFs), each respective active channel having one or more CSFs in the guide MLC. The decoder in the system is operative to decode a set of the plurality of CSFs from the guide MLC. The decoder simultaneously displays programming content of the decoded set of the plurality of CSFs on a display and automatically switches to a primary bitstream of an active channel associated with a selected one displayed CSF.

Abstract: This disclosure describes techniques for adjusting encoding variables of an encoding device. In response to a request to resize a segment of data, an encoding module adjusts at least one encoding variable used to encode one or more subsequent segments of data such that the subsequent segments of data are encoded at a bit rate that is different than the bit rate at which the subsequent segments of data would have been encoded had there been no request to resize. At some point, the encoding module re adjusts the encoding variables used to encode the segments of data such that the subsequent segments of data are encoded to achieve a desired encoding result. For example, the encoding module may re adjust the encoding variables after a period of time or may incrementally adjust the encoding variables until the encoding variables result in achieving the desired encoding result.
