Abstract :
This paper presents a recently developed fourth standard that meets the China´s unique needs. In China, the proportion of television viewers using terrestrial reception is pretty high. Other characteristics of China´s TV audience made it necessary to develop a new digital terrestrial television broadcasting standard that provides high-quality multimedia service as well. Field trials to date have demonstrated DTTB´s good performance, providing a solid foundation for building on these applications. We´re very willing to collaborate with people from academic, engineering, and industrial groups to improve the DTTB standard in the future.
