Abstract: 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 or might not include a cache. A client device can be adapted to take advantage of the ingestion process as well as including improvements that make for a better presentation independent of the ingestion process. In the block-request streaming system, the an ingestion system generates data according to erasure codes and the client device, through various selection and timing of requests for media data and redundant data, can efficiently decode media to provide for presentations.

Abstract: A method, an apparatus, and a computer program product are provided in connection with facilitating hybrid unicast/broadcast service distribution. In one example, a communications device is equipped to provide a parity portion of titles in a channel of a service to a plurality of UEs at a first time, receive, from a UE at a second time, a request to access a title of the one or more titles, and provide an enablement item, to the requesting UE, which is a portion of the requested title that, when processed with the provided parity portion of the requested title, is sufficient to allow the requesting UE to decode and access to the requested title. In an aspect, the parity portion may be a parity portion of a fountain code encoded title, and the enablement item may be repair symbols of the fountain code encoded title.

Abstract: In one example, a device includes one or more processors configured to receive a first segment of media data, wherein the media data of the first segment comprises a stream access point, receive a second segment of media data, wherein the media data of the second segment lacks a stream access point at the beginning of the second segment, and decode at least a portion of the media data of the second segment relative to at least a portion of data for the first segment. In this manner, the techniques of this disclosure may be used to achieve a Low Latency Live profile for, e.g., dynamic adaptive streaming over HTTP (DASH).

Abstract translation: 在一个示例中，设备包括配置成接收媒体数据的第一段的一个或多个处理器，其中第一段的媒体数据包括流接入点，接收媒体数据的第二段，其中第二段的媒体数据 段在第二段的开头处缺少流接入点，并且相对于第一段的数据的至少一部分来解码第二段的媒体数据的至少一部分。 以这种方式，本公开的技术可以用于实现例如通过HTTP（DASH）的动态自适应流传输的低延迟实时配置文件。

Abstract: Embodiments enable HTTP servers to pass incomplete and/or corrupted files in response to file requests from clients. In the various embodiments, HTTP servers may be enabled to generate status codes identifying that an incomplete version of a file is being returned in response to a file request. In an embodiment, an HTTP server may be enabled to determine the ability of a client to handle incomplete versions of files.

Abstract translation: 实施例使HTTP服务器能够响应来自客户端的文件请求传递不完整和/或损坏的文件。 在各种实施例中，可以使HTTP服务器能够生成识别文件的不完整版本正在被响应于文件请求被返回的状态代码。 在一个实施例中，可以启用HTTP服务器来确定客户端处理不完整版本的文件的能力。
