摘要： Video decoding innovations for multithreading implementations and graphics processor unit (“GPU”) implementations are described. For example, for multithreaded decoding, a decoder uses innovations in the areas of layered data structures, picture extent discovery, a picture command queue, and/or task scheduling for multithreading. Or, for a GPU implementation, a decoder uses innovations in the areas of inverse transforms, inverse quantization, fractional interpolation, intra prediction using waves, loop filtering using waves, memory usage and/or performance-adaptive loop filtering. Innovations are also described in the areas of error handling and recovery, determination of neighbor availability for operations such as context modeling and intra prediction, CABAC decoding, computation of collocated information for direct mode macroblocks in B slices, reduction of memory consumption, implementation of trick play modes, and picture dropping for quality adjustment.

摘要： A browser-based email system has a thin client connected to a host mail server. The thin client implements a browser. The host mail server provides pages to the thin client, which can be rendered by the browser to present an email service to a user. The thin client is equipped to receive audio and video data and supports a user interface to facilitate capture of the audio or video data for inclusion in an email message. After a data stream is captured and stored locally at the client, the browser submits a request to the host mail server that contains a token in lieu of the data stream. The host mail server returns a response specifying a new page that contains the email message. The response also includes the token and indicates a location in the new page at which the audio or video data is to be rendered. Upon receiving the response, the browser inserts the data stream into the new page at the location and renders the new page. After the user has reviewed the email message, the user can send the email message, causing the browser to submit another request to the host mail server that contains both the email message and the audio or video data. Upon receiving this second request, the host mail server converts the email message and the audio or video data to a MIME message and forwards the MIME message to the intended recipient.

摘要： A method for filtering data to be compressed by frame differencing is disclosed. In applications where large amounts of data must be either stored or transmitted, such as, for example, digital image data, various techniques are used to compress the data. One such technique is frame differencing wherein after a reference frame or key is encoded, only the differences between each frame and the immediately preceding frame in the sequence are encoded. The present invention operates as a pre-process or in conjunction with such a technique by determining which of the changed data points can be disregarded without significantly affecting, for example, the stored image, thereby reducing the amount of data which must be stored or transmitted. The determination is made in the present invention by comparing the pattern of changed data points in the vicinity of the data point under consideration with a set of pre-determined patterns.

摘要： The invention frees up memory to other uses by allocating memory to video graphics buffering only to the extent required. It also saves graphic processor bandwidth by processing, e.g. blending, only to the extent required. It does so by defining a regular grid of so-called tiles or cells in the overlay graphic data window, e.g orthogonally arrayed squares of 32-pixel sides, and allocating memory only to those requiring update, i.e. only those that are visible and subject to change between successive frames. Allocation is dynamic and requires little tagging overhead to keep track of the tiles in memory by location in the video graphic window. Processing is only of those tiles for which memory is allocated, since entirely transparent tiles within the window require no blending or processing whatsoever because they are invisible. In one implementation, only onscreen buffered graphics are tiled and the offscreen buffered graphics require full-sized memory allocation and in another offscreen buffered graphics are tiled also by clipping within variously sized buffers during successive passes through a drawing operation wherein the various sized buffers all are smaller than the entire window. New offscreen buffer-processed tiles may be swapped as they are processed for existing (visible) onscreen tiles directly, when there is less available memory, or new tiles may be processed and block-stored in memory until a wholesale swap can occur invisibly, when there is more memory available.

摘要： A method and apparatus for lossless compression and decompression of video image data. Video data is comprised of the RGB, YUV or gray scale (color) information for each pixel of each frame of the video data. Storage of such video data can require large amounts of data. The present invention provides for lossless compression and decompression of the individual frames of video image data. Each individual frame of video image data is processed in n.times.n pixel blocks. The combination of colors (called the color list) and the number of different colors in the pixel block is then determined. If the number of colors is above a predetermined threshold, no compression occurs. If the number of colors is below a predetermined threshold, searches for prior occurrences of the combination of colors is than performed. In some instances, a color list for contiguous pixel blocks will be the same. In this instance, a pixel map representing the positioning of the colors in the pixel block is output. Further, each encountered combination of colors is stored as an entry in a color cache. The color cache is subsequently used as a color combination dictionary. In such instances of a pixel block where its color list is in the color cache, an index to the entry into the color cache is used to represent the colors found in the pixel block. The color cache need not be stored with the compressed data stream since it is reconstructed during decompression of the compressed data stream.

摘要翻译： 一种用于无损压缩和解压缩视频图像数据的方法和装置。 视频数据由视频数据的每帧的每个像素的RGB，YUV或灰度（彩色）信息组成。 这种视频数据的存储可能需要大量的数据。 本发明提供了视频图像数据的各个帧的无损压缩和解压缩。 视频图像数据的每个单独帧以n×n个像素块进行处理。 然后确定颜色（称为颜色列表）的组合和像素块中的不同颜色的数量。 如果颜色数高于预定阈值，则不发生压缩。 如果颜色数量低于预定阈值，则搜索颜色组合的先前出现。 在某些情况下，连续像素块的颜色列表将相同。 在这种情况下，输出表示像素块中的颜色定位的像素图。 此外，每个遇到的颜色的组合被存储为颜色高速缓存中的条目。 颜色缓存随后用作颜色组合字典。 在其颜色列表在颜色高速缓存中的像素块的这种情况下，使用到颜色高速缓存中的条目的索引来表示在像素块中找到的颜色。 因为在压缩数据流的解压缩期间重构颜色高速缓存不需要与压缩数据流一起存储。
