摘要： A technique for streaming digital video content to a client involves providing a new stream of digital video content to the client using forward error correction (FEC) for a limited initial period and then ending the use of FEC after the limited initial period has ended. In an embodiment, during the limited initial period, the digital video content is provided to the client at a rate that is slightly higher than the playout rate in order to allow a client buffer to accumulate digital video content. FEC continues to be used until the client buffer is sufficiently populated such that lost or damaged frames can be retransmitted to the client before the corresponding digital video content is needed for playout. Once the client buffer is sufficiently populated, FEC is ended and retransmission is used to maintain the quality of the streamed digital video content.

摘要： A data processing system buffers temporarily a portion of a plurality of compressed data streams. Each portion comprises one or more units of an encoded media signal. A switch provides selective connectivity between the buffer and a plurality of processors analyzing the one or more units of the encoded media signal in the buffer and generating statistical data about the encoded media signal. One or many transcoders are configured to decode a second portion of the compressed data streams, which includes units ordered ahead of the one or more units in the buffer, and then encode the second portion of the compressed data streams based on the statistical data. A controller receives the statistical data from the processors and directs the encoding of the second portion of the compressed data streams.

摘要： Systems and methods of encoding a video signal that includes a succession of images are disclosed. A system may include a plurality of independently programmable processing elements (PEs), an input interface device adapted to receive, buffer, and divide the input video signal in a manner appropriate to the plurality of PEs, and an output interface device adapted to receive encoded bitstreams generated by the plurality of PEs and provide an encoded video signal. Each PE is configurable to carry out the steps of a selected encoding algorithm and includes a digital processor and a memory in communication with the digital processor. The memories are independently accessible, and PEs communicate with each another during the encoding.

摘要翻译：用于将数字视频内容流式传输到客户端的技术涉及在有限的初始时段内使用前向纠错（FEC）向客户端提供新的数字视频内容流，然后在有限的初始时段结束之后结束FEC的使用。在一个实施例中，在有限的初始时段期间，数字视频内容以略高于播放速率的速率被提供给客户端，以便允许客户机缓冲器累积数字视频内容。 FEC继续被使用，直到客户端缓冲器被充分填充，使得丢失或损坏的帧可以在需要相应的数字视频内容进行播放之前重新发送到客户端。一旦客户端缓冲器被充分填充，则FEC结束，并且使用重传来维持流式数字视频内容的质量。
