Current Activities (2)
• Application part
– Developing standards to specify an access-agnostic interoperable Mobile
Multimedia Broadcast Service
– Recently completed work:
• Technical Report completed
– Providing proposed solutions and recommendation for Mobile Multimedia
Broadcast Service standardization
• Technical Specifications, providing
– The general requirement,
– The service protection requirement

Strategic Direction
•
The CCSA MMBS standards development has been defined in three phases:
– Phase 1: Requirement and Technical research
– Phase 2: Requirement and Technical specifications
– Phase 3: Test specifications
•
Convergence
– The High Level Architecture to connect the different industry (The business cooperation
between telecommunication industry and broadcast)
– Service protection:
• Smartcard profile
• Key exchange interface
– Service Guide
– Service Interactive
•
•
The CCSA MMBS standards align with the work of other SDOs: OMA, 3GPP,
3GPP2
The CCSA MMBS standards mainly focus on the service and application domain.
4
Challenges
• Application
– Gaps between telecommunication operation and broadcast operation
– Service Protection interface be accept by both role
– Service protection solution for Non-communication terminal
• Significant discussion on the connection between telecommunication
operation and broadcast operation
– Architecture
– Service protection
– Service guide
5
Next Steps/Actions
• Application
– Test
– Instruct the business cooperation between telecommunication
industry and broadcast
– Service protection solution for Non-communication terminal
– Content Protection
