摘要： A method and apparatus for decompressing compressed data, which includes video data that has been compressed in accordance with the MPEG 2 standard, wherein the processing begins by retrieving components from a non-local memory at a rate that is independent of the rate in which the components were written into the non-local memory. The components include motion vectors and run/level data. As the components are retrieved from memory, the run/level data is used to produce representations of the uncompressed data. As the representations of the uncompressed data are generated, they are processed based on the motion vector data to recapture the uncompressed data. The uncompressed data is then stored in a frame buffer for subsequent display.

摘要： A method and apparatus for co-processing multi-formatted data which begins when a host processor writes data blocks, in a substantially continuous manner, into memory. Each of the data blocks includes a plurality of data elements and each data element has one of a plurality of data formats. As the data block is being stored in memory, a co-processor retrieves selected data elements from the memory. Upon retrieving the selected data elements, the co-processor interprets them to identify the data format. If the data format is consistent with the data format of the co-processor, the co-processor processes the data element without conversion. If, however, the data format of the selected data element is not consistent with the data format of the co-processor, the co-processor converts the format of the selected data element into the format consistent with the co-processor.

摘要： A system and a method for simultaneous transmission of multiple media streams in a fixed bandwidth network are disclosed herein. The system is comprised of a central gateway media server and a plurality of client receiver units. The input media streams arrive from an external source and are then transmitted to the client receiver units in a compressed format. A state machine on the gateway media server detects if the network bandwidth is close to saturation. In one embodiment, the potential bandwidth saturation is measured by matching the time when the start of unit of media for each stream against the estimated transmission time for that unit. When any one actual transmission time exceeds its estimated transmission time by a predetermined threshold value, the network is deemed to be close to saturation, or already saturated, and the state machine executes a process of selecting at least one stream as a target for lowering total bandwidth usage. Once the target stream associated with a client receiver unit is chosen, the amount of data transmitted by the target stream is reduced, which could result in a lower data transmission rate. In one embodiment, the amount of data is reduced by a gradual degradation of the precision of the data, resulting in a greater potential for data compression, and/or by gradually reducing the resolution of the data of the target stream.

摘要： A video decoding device includes a metadata extraction device that extracts metadata and a video signal from a processed video signal, wherein the metadata is time-coded in accordance with at least one time stamp of the video signal. The metadata extraction device generates a selected portion of the metadata based on selection data and the metadata. A metadata display generator generates metadata display data in response to the selected portion of the metadata. A video decoder decodes the video signal to generate a decoded video signal. An output interface generates a video/metadata output by synchronizing the metadata display data to the decoded video signal in accordance with the at least one time stamp.

摘要： A technique for encoding and decoding video information uses a plurality of video processing modules (VPMs), whereby each video processing module is dedicated to a particular video processing function, such as filtering, matrix arithmetic operations, and the like. Information is transferred between the video processing modules using a set of first-in first-out (FIFO) buffers. For example, to transfer pixel information from a first VPM to a second VPM, the first VPM stores the pixel information at the head of a FIFO buffer, while the second VPM retrieves information from the tail of the FIFO buffer. The FIFO buffer thus permits transfer of information between the VPMs without storage of the information to a cache or other techniques that can reduce video processing speed.

摘要翻译：本文公开了一种在固定带宽网络中同时传输多个媒体流的系统和方法。该系统由中央网关媒体服务器和多个客户机接收机单元组成。输入媒体流从外部源到达，然后以压缩格式发送到客户接收器单元。网关媒体服务器上的状态机检测网络带宽是否接近饱和。在一个实施例中，通过将每个流的媒体单元的开始与该单元的估计传输时间的时间匹配来测量潜在带宽饱和度。当任何一个实际传输时间超过其估计传输时间预定阈值时，网络被认为接近饱和或已经饱和，并且状态机执行选择至少一个流作为目标的处理以降低总数带宽使用。一旦选择了与客户机接收机单元相关联的目标流，则由目标流发送的数据量减少，这可能导致较低的数据传输速率。在一个实施例中，通过数据的精度的逐渐劣化来降低数据量，从而导致更大的数据压缩潜力和/或通过逐渐降低目标流的数据的分辨率。

摘要： A method and apparatus for controlling access to a video system based on bandwidth consumption include processing that begins as the server monitors bandwidth utilization of connections within the video system. The processing continues when the server receives a request to access a video program via the connection from a client device of the video system. The processing then continues as the server determines whether determine whether the client device has subscribed to receive the video program at the first quality level. When the client device has not subscribed to receive the video program at the first quality level, the video quality of the video program is converted from the first quality level to a video quality subscribed to by the client device.

摘要： A local system encodes previously decoded video data using a transcoding quantization value based on a source quantization value provided by a previous encoder as part of the retrieved video data. The transcoding quantization value can be determined additionally based the fullness of the video buffer of a target system, where a measure of the fullness can be obtained directly from the target system or modeled by the local system. The video data is encoded by the local system and then provided to a target system for decoding and subsequent display and/or storage.
