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. 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.

Abstract translation: 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。

Abstract: The aspects enable a processor to concurrently execute a first serial language code embedding a second serial language code during a page load by a browser. A parser parses the first serial language code until a segment of the embedded second serial language code is encountered. The segment of embedded second serial language code is extracted for execution by an execution engine, which proceeds concurrently with speculative parsing of the first serial language code. Code generated by execution of second serial language code is evaluated to determine if it is well-formed, and partial rollback and re-parsing of the first serial language code is performed if the code is not well-formed. Concurrent parsing of first serial language code and execution of second language code, with partial roll back and reparsing when necessary, continues until the first language code has been parsed and the second serial language code has been executed.

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 block-request streaming system provides for low-latency streaming of a media presentation. A plurality of media segments are generated according to an encoding protocol. Each media segment includes a random access point. A plurality of media fragments are encoded according to the same protocol. The media segments are aggregated from a plurality of media fragments.

Abstract: The aspects enable a processor to concurrently execute markup language code (e.g., HTML) having embedded scripting language code (e.g., JAVASCRIPT®) during a page load operation by a browser. A markup language parser parses markup language code until embedded scripting language code is encountered. The segment of embedded scripting language code is extracted for execution by a scripting language engine which proceeds concurrently with speculative parsing of the markup language code. Markup language code generated by execution of scripting language code is evaluated to determine if it is well formed, and a partial rollback of the markup language parse and re-parsing of portions of the markup language code is accomplished if not. Concurrent parsing of markup language code and execution of scripting language code, with partial roll back of the parsing process when necessary, continues until all markup language code has been parsed and all scripting language code has been executed.
