摘要： In one example, a device includes one or more processing units configured to send, via a network, a request to retrieve at least a portion of media content, wherein the media content conforms to dynamic adaptive streaming over HTTP (DASH), and wherein the request comprises a request that the at least portion be delivered according to a file delivery service, and, in response to the request, to receive streaming data for the at least portion of the media content in accordance with the file delivery service over the network. The device may prepopulate a browser cache with the received data, such that a browser can, in effect, stream data using the file delivery service. The device may initially retrieve data of the media content using unicast, until a switch point of the data received via the file delivery service is reached.
摘要翻译： 在一个示例中，设备包括被配置为经由网络发送用于检索至少一部分媒体内容的请求的一个或多个处理单元，其中所述媒体内容符合通过HTTP（DASH）的动态自适应流传输，并且其中 请求包括根据文件传送服务传递至少部分的请求，并且响应于该请求，根据网络上的文件传递服务接收媒体内容的至少部分的流式传输数据。 设备可以预先填充具有接收到的数据的浏览器缓存，使得浏览器实际上可以使用文件传递服务流式传输数据。 设备可以首先使用单播来检索媒体内容的数据，直到达到通过文件传送服务接收的数据的切换点。

摘要： A method of generating Source Identification information from a source packet stream and reliably transmitting the Source Identification information from a source to a destination over a communications channel is provided. The method operates on a set of source packets, wherein Source Identification information for each source packet to be transmitted is derived and delivered with the Source Identification information of all or most other source packets of an associated source block. The method includes techniques to minimize the network bandwidth required to deliver Source Identification information and techniques to overcome network impairments. When combined with FEC techniques, retransmission techniques, or combinations of FEC techniques and retransmission techniques, the methods described herein allow receivers to recover lost source packets, while simultaneously ensuring that the original source packets are not modified and thereby ensuring backwards compatibility for legacy receivers.

摘要： A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server, which might include a cache. A client device can be adapted to take advantage of the ingestion process as well as improvements that make for a better presentation independent of the ingestion process. The client devices and ingestion system can be coordinated to have a predefined mapping and template for making block requests to HTTP file names that a conventional file server can accept through the use of URL construction rules. Segment size might be specified in an approximate manner for more efficient organization.
摘要翻译： 块请求流系统提供了这样的系统的用户体验和带宽效率的改进，通常使用以传统文件服务器（HTTP，FTP等）服务的形式生成数据的摄取系统，其中 摄取系统进入内容并将其准备为要由文件服务器（可能包括缓存）提供的文件或数据元素。 客户端设备可以适应于摄取过程的优点以及独立于摄取过程的改进。 可以协调客户端设备和摄取系统以具有预定义的映射和模板，以便通过使用URL构造规则对常规文件服务器可以接受的HTTP文件名进行块请求。 可以以近似的方式指定细分大小以提高组织效率。
