摘要： 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.

摘要： This application relates to systems and methods for recovering data in multimedia file segments. A communication device may receive a multimedia file segment that includes damaged data. The communication device may replace the damaged data with dummy data to reconstruct the multimedia file segment. The communication device may then play the reconstructed multimedia file segment. Thus, by replacing the damaged data with dummy data, the communication device may play a multimedia file segment even when part of the segment may be damaged.

摘要： Encoding of a plurality of encoded symbols is provided wherein an encoded symbol is generated from a combination of a first symbol generated from a first set of intermediate symbols and a second symbol generated from a second set of intermediate symbols, each set having at least one different coding parameter, wherein the intermediate symbols are generated based on the set of source symbols. A method of decoding data is also provided, wherein a set of intermediate symbols is decoded from a set of received encoded symbols, the intermediate symbols organized into a first and second sets of symbols for decoding, wherein intermediate symbols in the second set are permanently inactivated for the purpose of scheduling the decoding process to recover the intermediate symbols from the encoded symbols, wherein at least some of the source symbols are recovered from the decoded set of intermediate symbols.

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. The system might include controlling the sequence, timing and construction of block requests, time based indexing, variable block sizing, optimal block partitioning, control of random access point placement, including across multiple presentation versions, dynamically updating presentation data, and/or efficiently presenting live content and time shifting.
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，并将其准备为由文件服务器提供的文件或数据元素。 该系统可以包括控制块请求的序列，时序和结构，基于时间的索引，可变块大小，最佳块分割，随机接入点布置的控制，包括跨多个呈现版本，动态地更新呈现数据，和/或有效地呈现 实时内容和时间转移。

A client device can be adapted to take advantage of the ingestion process. The client device might be configured to optimize use of resources, given the information available to it from the ingestion system. This may include configurations to determine the sequence, timing and construction of block requests based on monitoring buffer size and rate of change of buffer size, use of variable sized requests, mapping of block requests to underlying transport connections, flexible pipelining of requests, and/or use of whole file requests based on statistical considerations.

摘要： 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).
