    • Systems and methods for dynamically chunking for delivery instances are provided that automatically implement chunking strategies based on one or more chunking considerations related to a request for a media file. These systems and methods may be part of a larger media servicing network that can be used to, among other things, process uploaded media content, provide it for streaming/downloading, and collect metric information regarding the streaming/downloading. The disclosed systems and methods provide for receiving a request having a Uniform Resource Locator (URL) and providing an index file to implement chunking strategies based on chunking considerations associated with the request.
    • 提供了用于递送实例的动态分块的系统和方法,其基于与媒体文件的请求相关的一个或多个分块考虑来自动实现分块策略。 这些系统和方法可以是更大的媒体服务网络的一部分,其可以用于处理上传的媒体内容,提供流媒体/下载以及收集关于流/下载的度量信息。 所公开的系统和方法提供用于接收具有统一资源定位符(URL)的请求,并提供索引文件以基于与请求相关联的分块考虑来实现分块策略。

    • Systems and methods for encrypting a media file for streaming and/or downloading over a network are disclosed. These systems and methods may be part of a larger media servicing network that can be used to, among other things, process uploaded media content, provide it for streaming, and collect metric information regarding the streaming. The disclosed systems and methods provide for receiving requests for a media file or a chunk of a media file and responding to these requests by encrypting the requested chunks dynamically and providing the chunks to the requesting entity. These systems and methods, which can be utilized with a dynamic chunk generation and dynamic index file generation, enable a high degree of flexibility in streaming chunked media files and preclude the need to encrypt the chunks prior to streaming. The systems and methods may also be applied to encrypting files for continuous streaming protocols as well as for progressive download.
    • 公开了用于加密媒体文件以用于通过网络流式传输和/或下载的系统和方法。 这些系统和方法可以是更大的媒体服务网络的一部分,其可以用于处理上传的媒体内容,提供流媒体以及收集有关流媒体的度量信息。 所公开的系统和方法提供用于接收媒体文件或媒体文件块的请求,并通过动态地加密所请求的块并向请求实体提供块来响应这些请求。 可以利用动态块生成和动态索引文件生成的这些系统和方法使流分块媒体文件具有高度的灵活性,并且排除在流传输之前加密块的需要。 系统和方法也可以应用于加密用于连续流协议的文件以及逐行下载。
