Exploration and Practice of CMMB Local Program Transmission |
|
| Abstract: | In recent years, construction of CMMB network is developing rapidly. Solving transmission of local programs is an element that commercial operators have to consider. In this paper, CMMB local signal transmission modes are explored and practiced, such as using SDH network to realize signal transmission from province to city, or without additional equipment to send encrypted satellite TV and unencrypted National Games TV at the same time.
