Abstract

This invention discloses a process method for stream media contents including: ciphering stream media content to generate corresponding authorization control information and management information, transmitting the stream media content, the control information and the management information to a terminal device, in which, each frame of the content is divided into multiple data packets to be transmitted and the authorization control information is transmitted during the transmission. This invention also discloses a condition receiving system and a process system of stream media content.

Description

technical field [0001] The invention relates to the technical field of streaming media, in particular to a processing method, device and system for streaming media content. Background technique [0002] In the development of various related services of streaming media, streaming media content is easy to copy and distribute. When there is a lack of security measures to protect streaming media content, the problem of piracy will inevitably appear. Thus, streaming media encryption protection technology is introduced. Through the encryption protection of streaming media content, content providers can protect their own content and control the distribution of content. [0003] The CA system (Conditional Access System, conditional access system) is one of the current encryption protection systems for streaming media, which realizes the protection of streaming media content through encryption and access control of streaming media content. The CA system mainly generates two types of...
