Services and trial test of CMMB system

This paper presents the experimental services and trial test of China Mobile Multimedia Broadcasting (CMMB) system. Combined with the comparison with another popular mobile TV standard DVB-H, the system infrastructure and key techniques of CMMB are introduced. We describe the coverage deployment of CMMB based on the existing trial test reports. Some aspects of its services in China are depicted. It is mentioned that due to the fast commercial operation deployment, CMMB has become the approachable handheld TV standard in China. It will try to expand its network coverage and set up mature commercial pattern in the near future although it is facing some shackles including the payment mode at present.
