Abstract: Multiple corruptions and/or erasures in data storage or data communication systems are corrected. An encoder generates M of parity fields from N data channels. Each item of the generated parity fields is the result of simple exclusive-or operations on one item from one or more data fields and possibly one item from one or more of the other parity fields. A decoder can regenerate as many as M missing or corrupted fields of either data or parity using combinations of correct and/or previously corrected items as inputs using M independent parity equations to solve for and correct each missing or corrupted item in turn.

Abstract: When two or more different video streams a e compressed for concurrent transmission of multiple compressed video bitstreams over a single shared communication channel, control over both (1) the transmission of data over the shared channel and (2) the compression processing that generates the bitstreams is exercised taking into account the differing levels of latency required for the corresponding video applications. For example, interactive video games typically require lower latency than other video applications such as video streaming, web browsing, and electronic mail. A multiplexer and traffic controller takes these differing latency requirements, along with bandwidth and image fidelity requirements, into account when controlling both traffic flow and compression processing. In addition, an off-line profiling tool analyzes typical video applications off-line in order to generate profiles of different types of video applications that are then accessed in real-time by a call admission manager responsible to controlling the admission of new video application sessions as well as the assignment of admitted applications to specific available video encoders, which themselves may differ in video compression processing power as well as in the degree to which they allow external processors (like the multiplexer and traffic controller) to control their internal compression processing.

Abstract: A PC-type computer has a system bus (e.g., a PCI bus) configured with a main CPU board, a statistical multiplexing (stat-mux) board, and a plurality of video/audio encoder boards, each configured to receive and compress a corresponding video/audio stream. The stat-mux board performs statistical multiplexing on the different compressed bitstreams to transmit multiple bitstreams over individual shared communication channels. Although each of the boards is configured to the system bus, each encoder board has a digital signal processor (DSP) with a synchronized serial interface (SSI) output port that is directly connected to an SSI input port on a DSP on the stat-mux board (which, in one embodiment, has four such DSPs each with six such SSI input ports). As such, (up to 24) compressed video/audio bitstreams generated on the various encoder boards can be transmitted directly to the stat-mux board without having to go through the system bus. In this way, the computer system can provide statistical multiplexing of low-latency video/audio bitstreams without having to suffer the processing delays associated with conventional transmission over PCI system buses.
Abstract translation: PC型计算机具有配置有主CPU板,统计复用(stat-mux)板和多个视频/音频编码器板的系统总线(例如,PCI总线),每个配置用于接收和压缩 相应的视频/音频流。 统计复用板对不同的压缩比特流执行统计复用,以在各个共享通信信道上传输多个比特流。 虽然每个板都配置为系统总线,但每个编码器板都有一个数字信号处理器(DSP),具有同步的串行接口(SSI)输出端口,它直接连接到数模转换器上的DSP上的SSI输入端口 板(在一个实施例中,具有四个这样的DSP,每个具有六个这样的SSI输入端口)。 因此,在各种编码器板上生成的(多达24个)压缩视频/音频比特流可以直接发送到统一复用板,而不必通过系统总线。 以这种方式,计算机系统可以提供低延迟视频/音频比特流的统计复用,而不必忍受与PCI系统总线上的常规传输相关联的处理延迟。
