DRM-based streaming media playing system

Abstract

The invention discloses a DRM (Digital Rights Management)-based streaming media playing system. The system comprises a data encryption processing server and a client player, wherein the data encryption processing server is used for performing data right encryption protection processing to data contents and for performing authorization encryption processing to authorization content information; and the client player is connected with the data encryption processing server and used for deciphering the authorization information and playing deciphered content information. By performing data right encryption protection processing to the content information, performing authorization encryption processing to the authorization content information, and deciphering the authorization information through the client player, the system performs HLS (Hue, Lightness and Saturation) adaptive streaming media playing to the deciphered content information. The system simultaneously supports the HFC (Hybrid Fiber-Coaxial) network, the telecommunication network and the internet, realizes the digital right streaming media deciphering and playing, can automatically detect network conditions during HLS adaptive streaming media playing and perform adaptive code rate, and has the advantage of short buffer time.

Description

Technical field [0001] The present invention relates to content digital copyright encryption protection technology (DRM), in particular to a DRM-based streaming media playing system. Background technique [0002] With the integration and development of telecommunication networks, radio and television networks, and the Internet to broadband communication networks, digital television networks, and the next-generation Internet, the technical functions of the three networks will tend to be the same, the business scope will tend to be the same, and the network will achieve interconnection and resource sharing. So as to provide users with multiple services such as voice, data and broadcast television. The Internet TV service (Over The Top TV, OTT TV) that emerged on this basis integrates multiple technologies such as the Internet, multimedia, and communications, and can provide home Internet TV users with a variety of interactive services including digital TV. [0003] At present, OTT T...

AI Technical Summary

Problems solved by technology

[0008] In view of this, the purpose of the present invention is to provide a DRM-based streaming media playback system to solve the problem that the current client player of the current OTT service cannot realize the multi-network support of HFC, telecommunications and the Internet

[0010] In addition, the DRM-based streaming media playback system provided by the present invention is also used to solve the problem that the current OTT service client player cannot self-detect the network status, automatically switch to the highest bit rate in the current environment, and the loading video buffer time is long The problem
