IEC 62766-7-2017 消費者獲取IPTV終端功能和開(kāi)放互聯(lián)網(wǎng)多媒體服務(wù)--第7部分:認證、內容保護和服務(wù)保護 Consumer terminal function for access to IPTV and open internet multimedia services – Part 7: Authentication, content protection and service protection

This part of IEC 62766 specifies functions for content protection, service protection, service access protection, user identification, user authentication, and user authorisation. 
The following clauses contain features for which the criteria that determine under which 
circumstances these features are implemented are out of the scope of the present document 
or contain conditional normative statements referring to other parts of IEC 62766: 
• 4.2 Terminal-centric approach 
• 4.2.5 Protected file formats 
• 4.2.6 Protection of MPEG-2 transport streams 
• 4.3.4 CI+ based gateway 
• 4.3.4.7 Protected streaming and file formats 
• 4.3.4.8 Personal video recorder 
• 4.3.4.9 Time shifting 
• 4.3.5 DTCP-IP based gateway 
• 4.3.5.6 Protected streaming and file formats 
• 5.4.4 HTTP digest authentication using IMS gateway 
• 5.4.5 GBA authentication using IMS gateway 
NOTE GBA authentication can be achieved using either the mechanism in 5.4.5 GBA authentication using IMS gateway or the, more general, mechanism in 5.4.4 HTTP digest authentication using IMS gateway. 5.4.4 allows the use of different authentication mechanisms in a way that is transparent to the OITF, including possible future 
authentication mechanisms, and should preferably be used. It is expected that 5.4.5 GBA authentication using IMS gateway will be deprecated and removed in future versions of this specification.dition 1.0 2017-07 INTERNATIONAL STANDARD colour inside Consumer terminal function for access to IPTV and open internet multimedia services – Part 7: Authentication, content protection and service protection IEC 62766-7:2017-07(en) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2017 IEC, Geneva, Switzerland All rights reserved.
