摘要： A method allows a designer to implement software for a wide variety of variant host architectures, without excessive usage of host memory (52). The method is based on providing an initialization module of the software to host memory (52). A portion of the initialization module determines the host architecture. The unneeded portions of the initialization module are freed, and needed portions are relocated into a contiguous memory space to minimize host memory usage. Any location dependent entries in the needed portions of the program are then updated based on the relocation. The initialization module includes a plurality of code blocks, (16, 18, 20, 22), each of which is optimized to a particular variant architecture. When the variant architecture of the host is identified, those code blocks which are optimized to the identified host are selected and the other code blocks are freed. The selected blocks are then relocated to optimize host usage.

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流，然后在有限的初始时段结束之后终止使用FEC。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。继续使用FEC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传送到客户端。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。

摘要： A technique for transitioning streamed digital video content between stream servers involves identifying a transition identifier that indicates a point at which streaming of the digital video content transitions from a first stream server to a second stream server and then transitioning the streaming from the first stream server the second stream server at a point in the digital video content that corresponds to the transition identifier. For example, the first stream server stops streaming the digital video content at a point in the digital video content that corresponds to the transition identifier and the second stream server starts streaming the digital video content at a point in the digital video content that corresponds to the transition identifier.
