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： Data objects are delivered over a packet-switched network and receivers receive encoded symbols, such as repair symbols, broadcast or multicast, with sufficient information to form requests for additional symbols as needed based on what source symbols or sub-symbols are needed or missing. The requests can be made in a unicast or request fashion. Requesting and broadcasting might be done by different entities. A broadcast server can generate and store repair symbols while a source server can store content in source form. A request can be a unicast HTTP byte-range request, such as a URL, starting position and length. Requests might be aligned with starting positions of files. A receiver can calculate starting and ending byte positions of symbols or sub-symbols in a file and get indications that conventional HTTP servers are usable for file repair. Repair servers can request broadcast of repair data when byte-range requests from multiple receivers overlap.
摘要翻译：数据对象通过分组交换网络传送，并且接收机根据需要或基于哪些源符号或子符号需要或丢失，根据需要接收具有足够信息的编码符号（如修复符号，广播或多播）以形成对附加符号的请求。请求可以以单播或请求方式进行。请求和广播可能由不同的实体完成。广播服务器可以生成和存储修复符号，而源服务器可以以源形式存储内容。请求可以是单播HTTP字节范围请求，例如URL，起始位置和长度。请求可能与文件的起始位置一致。接收器可以计算文件中符号或子符号的开始和结束字节位置，并获得常规HTTP服务器可用于文件修复的指示。当来自多个接收器的字节范围请求重叠时，修复服务器可以请求广播修复数据。

摘要： A file (FI) is transmitted via a first channel (CH1). In addition, a second channel (CH2) is used to transmit play parameters (D1, D2, R1, R2) which comprise at least one set (Di, Ri) of information about a play rate (R1, R2) and a delay time (D1, D2) for the file (FI) which is to be transmitted by the first channel (CH1). On the basis of the play parameters (D1, D2, R1, R2), it is possible to determine a time for starting to process the file (FI) which is to be transmitted.
