摘要： A system, method, and computer-readable medium that provides a streamed presentation to multiple clients over a network utilizing a presentation server that produces and streams audio, video, and uniquely identified auxiliary data objects (e.g., slides, 3D image models, sound bytes, web page, etc.) in separate sessions or channels over a network; a transmit queue associated with the presentation server to store uniquely identified repeatable auxiliary data objects; and a client that renders all data objects and stores the auxiliary data objects in a local memory cache so that they may be recalled according to their unique ID tags. The presentation server sends unique ID tags rather than the auxiliary data object content when repeated during the presentation. The client is responsive to unique ID tags to obtain an auxiliary data object from a local memory cache to render auxiliary content that is repeatedly presented during the presentation. A secondary network session may be made available to clients that join after the start of the presentation in order to obtain current auxiliary content.

摘要： An improvement to a predictive video encoding method or apparatus that includes selecting a mode class within which to choose an encoding algorithm to encode individual blocks of video information. Rather than implementing each algorithm in each mode class to ascertain an acceptable compression, the improvement eliminates searching through a class of encoding modes based simply on heuristics. The method comprises obtaining statistical information related to previous blocks of encoded video information, determining a mode class within which to chose a particular encoding algorithm based on the statistical information (e.g., heuristics) gathered, choosing an algorithm within the selected mode class using conventional techniques, and encoding the video information according to the chosen algorithm. Statistical information may include quantization parameters, prior encoding decisions, intensity or frequency values, or Hadamard transform coefficients of previously encoded macroblocks. Encoding complexity in the coder is reduced since one class of encoding modes is eliminated.
摘要翻译：一种预测性视频编码方法或装置的改进，包括选择在其中选择编码算法来对各个视频信息块进行编码的模式类别。不是在每个模式类中实现每个算法以确定可接受的压缩，而是改进消除了仅仅通过启发式来搜索一类编码模式。该方法包括获得与先前编码视频信息块相关的统计信息，基于收集的统计信息（例如，启发式）确定选择特定编码算法的模式类别，使用常规技术选择所选模式类别内的算法，并根据所选择的算法对视频信息进行编码。统计信息可以包括量化参数，先前编码决定，强度或频率值，或先前编码的宏块的Hadamard变换系数。由于消除了一类编码模式，因此编码器中的编码复杂度降低。

摘要： An encode control strategy is provided for variable bit rate encoding of a sequence of video frames in a single pass. The control strategy includes determining whether a video frame has a complexity level statistically outside a defined range from a complexity level of at least one preceding frame of the sequence of video frames, and if so, determining a new average bit rate target for the video frame. The new average bit rate for the video frame is determined employing at least one of spatial complexity and temporal complexity of the video frame. The new average bit rate target for the video frame is used to set frame level bit rate control parameter(s), and the video frame is encoded using the set frame level bit rate control parameter(s).

摘要： A method and apparatus, particularly suited to SIMD instruction sets, to filter streaming video information encoded under a predictive encoding algorithm specified under video encoding standards, such as MPEG 4 or H.264/AVC. The filtering operation de-blocks or removes unwanted borders in the perceived video. During the filtering process, a series of filtering mask is generated based on temporal and spatial statistics of predictive encoded video information, which is then recursively applied to the video in order to gate filtered or unfiltered video to an output channel according to coefficients of the masks. The filtering mask effectively yields a decision or rule-based map that transforms the video on a pixel-by-pixel basis thereby avoiding complex and processor-intensive decision tree logic customarily required to process individual pixels of successive macroblocks that may have different filtering requirements.

摘要： A system for the introduction of controlled correlation among multiple redundant representations of predictively encoded signals while avoiding predictive mismatch at a receiver when any given sub-set of the multiple representations is received. The system embodies a signal encoder and decoder. The decoder can comprise at least two signal adders for respectively receiving coefficient values and adding at least one predictive value transform to the coefficient value in order to generate and transmit a second set of coefficient values. The second set of coefficient values is subsequently received by a decoder means, wherein the decoder means transforms the received coefficient values and transmits the resultant coefficient values to a signal adder. Upon reception of the transformed coefficient values, the signal adder generates a third set of coefficient values; the third set of coefficients being used to reconstruct an approximate version of an encoded signal.
