    摘要： Techniques are disclosed for improving user experience of multimedia streaming over computer networks. More specifically, techniques presented herein reduce (or eliminate) latency in playback start time for streaming digital media content resulting from digital rights management (DRM) authorizations. A streaming media client (e.g., a browser, set-top box, mobile telephone or tablet “app”) may request a “fast-expiring” license for titles the streaming media client predicts a user is likely to begin streaming. A fast-expiring license is a DRM license (and associated decryption key) which is valid for only a very limited time after being used for playback. During the validity period of such a license, the client device requests a “normal” or “regular” license to continue accessing the title after the fast-expiring license expires.

    摘要： A method of encoding data for transmission from a source to a destination over a communications channel is provided. The method operates on an ordered set of input symbols and includes generating a plurality of redundant symbols from the input symbols based on linear constraints. The method also includes generating a plurality of output symbols from a combined set of symbols including the input symbols and the redundant symbols based on linear combinations, wherein at least one of the linear constraints or combinations is over a first finite field and at least one other of the linear constraints or combinations is over a different second finite field, and such that the ordered set of input symbols can be regenerated to a desired degree of accuracy from any predetermined number of the output symbols.

    摘要： Framing techniques for an improved radio link protocol used in a wireless communication system, such as EV-DO. In one embodiment scheduling of the generation of repair symbols encoded to be transmitted along with source data is described. In another embodiment acknowledgment messages from a receiver are used to control the trailing edge of the protection window offered by the repair symbols. In another embodiment, non-acknowledgment messages from a receiver are used to control the generation of extra repair symbols. In another embodiment, a length field is used to avoid transmission of padding bytes over the air. In yet another embodiment, a symbol auxiliary field is appended to source symbols to indicate the padding bytes needed for symbol aligning thus avoiding the transmission of padding bytes over the air.

    摘要： Combining parallel Hypertext Transfer Protocol (HTTP) connections and pipelining overcomes an impact of increasing Round Trip Time (RTT) by varying in real time the number of parallel connections and pipelined requests such that the number of outstanding requests is minimal and the link remains fully utilized. Optimal construction and scheduling of requests and connections in an HTTP stack improves page load time and also provides for greater responsiveness to changes in object priorities. Multi-homing and mobility at the application layer for HTTP are addressed. Multi-homing provides for simultaneous use of multiple interfaces, for example WWAN and WLAN interfaces which improves download time, especially in the case that the available bandwidth the interfaces is of the same order of magnitude. Mobility provides for switching connections as the device moves. In combination they provide for smoother mobility. Mobility can be provided this way without server or network support.

    摘要翻译： 并行超文本传输​​协议（HTTP）连接和流水线结合克服了增加往返时间（RTT）的影响，通过实时变化并行连接和流水线请求的数量，使得未完成请求的数量最小并且链路仍然被充分利用 。 HTTP堆栈中的请求和连接的最佳构建和调度可以提高页面加载时间，并且还可以更好地响应对象优先级的更改。 解决HTTP应用层的多归属和移动性问题。 多归属提供同时使用多个接口，例如改善下载时间的WWAN和WLAN接口，特别是在接口具有相同数量级的可用带宽的情况下。 移动性在设备移动时提供交换连接。 结合起来，它们提供更流畅的移动性。 可以以这种方式提供移动性，无需服务器或网络支持。
