Single frequency network (SFN) has been widely used in digital terrestrial television broadcasting (DTTB) systems. In this paper, we propose a SFN structure for DTMB systems using satellite links as the main program distribution networks. The proposed structure is more suitable for constructing national wide or large area DTTB SFN under complicated environments. The network structure and key technologies...
The technological change in terrestrial television broadcast from Analog to Digital started in 1998. It's an inevitable change that each country has to face as part of the digitizing process that already has been taking place in many other services. Cuba adopted DTMB (GB 20600-2006) standard for Digital Terrestrial Television Broadcasting with 6MHz channel bandwidth and is currently in “simulcast...
The digital television terrestrial multimedia broadcasting standard was ratified on August 18, 2006, and is the mandatory digital television terrestrial broadcasting standard in China. DTMB defines the signal frame structure, the coding and modulation schemes, and adopts time-domain synchronous orthogonal frequency-division multiplexing technology using pseudo random sequence as both the guard interval...
We address in this paper the convergence issue of DTMB and DVB-H, which are the digital broadcast standards of China and Europe respectively. After thorough study on the similarities as well as the differences between the two standards in the physical layer, we proposed our very preliminary ideas to combine the two systems into a single device effectively as well as efficiently and this work is supported...
