摘要： The present invention teaches new solutions based on an alternative approach to controlling client behavior in adaptive streaming applications, namely, server managed adaptive streaming. in this approach, the client makes requests for streaming content and provides extra information about its behaviors, and the server verifies the information to determine if the requests can be granted. This way, even if the client is not trusted, its behaviors can be properly and effectively controlled. Moreover, all of the solutions resulting from adopting this server managed adaptive streaming approach fit into the MPEG/3GPP standards of Dynamic Adaptive Streaming over HTTP (DASH).
摘要翻译：本发明基于在自适应流应用中控制客户端行为的替代方法教授新的解决方案，即服务器管理的自适应流传输。在这种方法中，客户端请求流式传输内容并提供有关其行为的额外信息，并且服务器验证信息以确定是否可以授予请求。这样，即使客户端不受信任，也可以正确有效地控制其行为。此外，采用该服务器管理的自适应流传输方法所产生的所有解决方案都符合通过HTTP（DASH）的动态自适应流传输的MPEG / 3GPP标准。

摘要： A Dynamic Adaptive Streaming over Hypertext Transport Protocol (DASH) server component is disclosed. The DASH server component may comprise a memory, a processor coupled to the memory, and a transmitter coupled to the processor. The processor may be configured to generate one or more keys containing content protection information for media content, associate the keys with one or more segments of media content, store the keys in a DASH metadata track in the memory, and generate a media presentation description (MPD) specifying an association between the keys and the segments of media content. The transmitter may be configured to transmit the keys to at least one client independently of transmitting the media content and transmit the MPD to the at least one client.
