Streaming media digital rights management method, terminal and streaming media server

Abstract

The invention relates to the field of wireless communication, and discloses a streaming media digital rights management method, a terminal and a streaming media server. Two copyright management strategies for a high-speed network and a low-speed network respectively are designed for a communication network multipath bearing mode. In the high-speed network, it is guaranteed that streaming media is downloaded and played smoothly, and meanwhile a most comprehensive protection strategy is used for protecting the copyright of the streaming media. In the low-speed network, network bearing capacity is used for downloading low labels to guarantee the downloading and playing fluency of the streaming media by greatly reducing authorization objects corresponding to the downloaded flow labels, and meanwhile the safety of the streaming media is protected through the terminal. When the networks are switched over, the proper authority protection strategies are selected according to the bearing capacity of the switched networks, and the downloading and playing fluency of the streaming media and the safety of the streaming media are further guaranteed.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a streaming media digital copyright protection method, a terminal and a streaming media server. Background technique [0002] With the rapid development of mobile communication technology and multimedia technology, and the enhancement of multimedia services on mobile communication terminals, it becomes possible for users to use terminals to play streaming media from the Internet. Since multimedia files (such as movies) require more storage space, downloading the multimedia is time-consuming, and end users prefer to play streaming media directly. Streaming media content on regular networks has copyright protection. Even free content may not allow end users to repost at will. If there is no effective copyright protection scheme, users will cause such damage in a very short time after downloading streaming media. Streaming is distributed illegally. Streaming media from the In...

AI Technical Summary

Problems solved by technology

Additional downloading of permission objects on a low-speed network will make the network load heavier, making it more difficult to download stream tags, and consume more system resources

There is only one copyright protection strategy in the prior art, which cannot be applied to low-speed networks and network switching

[0019] 2. In the prior art, the multi-path bearer and switching of the communication link (mobile network and WLAN network) are not considered

When the terminal moves to a network that is more suitable for streaming media download and protection, it does not switch to the bearer network, nor does it switch to a suitable copyright protection strategy

[0020] 3. In the prior art, when the terminal downloads the streaming media through the 2 / 3G network, it does not create an exclusive PDP link, which causes other application software to share the PDP link and the streaming media download is not smooth

[0021] 4. In the existing technology, there is only one protection strategy after the download starts or during the download process. If the download of the permission object corresponding to a flow label fails, the flow label cannot be parsed, and subsequent downloads cannot be continued.
