摘要： A video display apparatus and method for displaying decoded video frames from an encoded video stream utilizes a display time difference determinator that detects a frame display time difference, on a per frame basis if desired, between a refresh rate based frame display time, and a video playback frame rate display time to generate frame display time difference data. This is done on a continuous basis to detect synchronization problems between video data that is to be displayed simultaneously with non-video data on a display device such as a progressive display screen. A pixel blender blends pixel data from an adjacent frame, such as an already reconstructed previous frame or next frame, to create a temporally adjusted frame based on the determined frame display time difference data.

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： 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.

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。
