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：用于对视频信息进行编码和解码的技术使用多个视频处理模块（VPM），由此每个视频处理模块专用于特定的视频处理功能，例如滤波，矩阵算术运算等。使用一组先进先出（FIFO）缓冲器在视频处理模块之间传送信息。例如，为了将像素信息从第一VPM传送到第二VPM，第一VPM将像素信息存储在FIFO缓冲器的头部，而第二VPM从FIFO缓冲器的尾部检索信息。因此，FIFO缓冲器允许在VPM之间传送信息，而不将信息存储到高速缓存或可以降低视频处理速度的其他技术。

摘要： A first data storage requirement of a first multimedia data representative of a multimedia program to be stored at a storage device is determined. An available remaining storage capacity of the storage device is determined. The first multimedia data is transcoded to generate a second multimedia data having a second data storage requirement that is less than the first data storage requirement if the first storage requirement exceeds the available remaining storage capacity of the storage device. Alternately, a second multimedia data stored at the storage device and representative of a second multimedia program is selected based on user preference information. The second multimedia data is transcoded to generate a third multimedia data having a lower data storage requirement. The third multimedia data is stored at the storage device in place of the second multimedia data to increase the available remaining storage capacity of the storage device.

摘要： A multimedia program type of a received multimedia data is determined. Based on the determined multimedia program type, a peak bit rate limit and/or an average bit rate limit are determined. In instances where a transrated version of the multimedia data is to be stored, a remaining storage capacity of a storage device is determined and the peak bit rate limit and/or the average bit rate limit can be adjusted based on the remaining storage capacity. The multimedia data then is transrated to generate transrated multimedia data that has a peak bit rate that does not exceed the selected peak bit rate limit and/or having an average bit rate that does not exceed the selected average bit rate limit. The transrating of the multimedia additionally can include the application of rule sets based on content characteristics. After transrating, the multimedia data can be transmitted via a network to a destination multimedia device, stored locally for subsequent use, or a combination thereof.

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.
