摘要： A system, method, and apparatus for reducing the video decoder processing requirements for rewinding a HITS stream are presented herein. During rewind of a HITS stream, the video decoder builds a clean reference picture. The clean reference picture is built by decoding each of the P-pictures in the EP-EP segment. However, because the P-pictures are not displayed, the decoder does not decode the portion of the P-picture below the last intracoded slice. The decoder can build the clean reference picture without decoding the portions of the P-pictures below the last intracoded slice because the subsequent pictures do not use the said portions for prediction.
摘要翻译：本文给出了一种用于降低用于重绕HITS流的视频解码器处理要求的系统，方法和装置。在HITS流的倒带期间，视频解码器构建干净的参考图片。通过对EP-EP段中的每个P图像进行解码来构建干净的参考图像。然而，由于不显示P图像，所以解码器不会在最后一个内部编码的切片之下对P图像的部分进行解码。解码器可以构建干净的参考图像而不对最后一个内部编码的切片之下的P图像的部分进行解码，因为后续图像不使用所述部分进行预测。

摘要： Presented herein are systems, methods, and apparatus for improving performance of video decoders during rewind and fast forward operation. Video decoder performance is improved by avoiding repetitive decoding of prediction pictures. When a decoded prediction picture is stored in a frame buffer, techniques are presented for decoding multiple pictures in the rewind order which are dependent thereon, displaying the picture directly from the frame buffer, and setting one type of prediction picture as another type of prediction picture.

摘要： A video processing system is operable to perform one or more display queue trick (DQT) operations utilizing decoded frames queued in memory. The decoded frames are generated from the start of random access points (RAPs) in frame segments in an encoded video stream. Location of RAPs may be determined during decoding of the encoded video stream. Exemplary encoding scheme comprise MPEG, AVC and/or VC1. The DQT modes include forward and/or reverse display modes. The used frames are selected based on determination of DQT mode parameters, queuing limitations and/or frame properties of selected and/or unselected frames in the frame segments. Frame properties comprise frame discardability and/or display inter-frame dependencies between selected and/or unselected frames. The video processing system is operable to jump to preceding and/or subsequent RAPs during DQT mode operations. The video processing system is also operable to skip one or more RAPs during such jumps.

摘要： A server may be used to handle at least some of processing of content retrieved via and/or derived from Internet access operations of a plurality of set-top boxes (STBs). Resource allocation and/or utilization, and/or tasks or applications performed in the server during the processing may be configured based on control data, which may be determined by the server and which may comprise capabilities of links between the server and each of the plurality of STBs, requirements of the tasks, characteristics of the content and/or the Internet access operations, user preferences and/or interactions, and/or content provider preferences. The server may dynamically reconfigure the tasks and/or resources based on monitoring of its operations and/or changes of the control data. Configuring tasks and/or resources may comprise time slicing access to resources that are commonly used during concurrent servicing of at least some of the plurality of STBs by the support server.

摘要： A method and/or system are described in which a server communicatively coupled with a set-top-box (STB) may predict a location of a pointer on a web browser running on the STB. The server may render the pointer based on the predicted pointer location. The server may send the rendered pointer to the STB, wherein the STB may composite a web page on the web browser based on the rendered pointer. The server may be synchronized with the STB based on event information received by the server from the STB such as, for example, keystroke events, click event, or other like event. The prediction of the pointer location may be based on actual pointer location information provided by the STB. A predetermined number of pointer locations may be predicted based on an actual pointer location and/or on a latency of a connection between the server and the STB.
