Publication number: 20110047134Abstract: A method and a system for controlling media playing and a metadata execution unit are provided. The metadata execution unit obtains metadata provided by a metadata providing unit, and executes corresponding metadata according to trigger information for executing metadata. The metadata execution unit generates media content control indication information according to an execution result, and sends the media content control indication information. A media content control unit then controls media content playing correspondingly according to the media content control indication information. By using the method and apparatus, metadata is distributed to a suitable network entity to be executed for controlling media playing. In this way, decentralized execution of a policy is achieved. Therefore, processing efficiency is improved.Type: ApplicationFiled: October 29, 2010Publication date: February 24, 2011Inventors: Ni Zhang, Dewen Zhang, Youzhu Shi, Baojian Qi
