From September 7th to 22nd 2012, National Engineering Laboratory for DTV(Beijing) associating Hongkong Radio Station and Television Broadcasts Limited (TVB), Asia Television Ltd (ATV), made field tests of Chinese terrestrial digital television transmission system- DTMB-A and E-DTMB (according to Hongkong’s request). The tests include the static places install technology and system of DTMB-A and E-DTMB.
The tests show that not only DTMB-A system able to be compatible with the existing equipment of BTMB system, but also its transmission capacity is greatly increased. Under the same transmission bitrate, the reception threshold and anti-interference ability of DTMB-A system are better than DTMB system, especially under the high efficient mode of DTMB-A system is able to achieve a reliable reception in the complicated environment of Hongkong. The tests also show that E-DTMB system is fully compatible with DTMB system, E-DTMB system has good performance at anti-interference and reception threshold for mobile TV reception.
During the tests, DTVNEL along with HongkongTV station, TVB and ATV also held a proseminar for DTMB evaluation system technology on September 21st in the hall of Hongkong TV station. This proseminar was hosted by mister Zhu Ri Chao who is an outstanding expert of digital television technology research in Hongkong. More than ninety people attended the meeting, including people who came from Hongkong administration of communication engineering association of film and television in Asia-Pacific, HongkongTV station, TVB and ATV along with people who engaged in media industry. At the meeting, Dai Jian Wen, the vice director of Hongkong TV station gave an excellent speech. Wang Jing Tao, Song Jian and Yang Zhi Xing who were the professors of our laboratory introduced the research ideas, core technology and development direction of DTMB-A and DTMB-E systems. Professor Pan Chang Yong introduces the test details.
After the meeting, exports from Hongkong see a demonstration system of DTMB-A and E-DTMB technology. They highly appraise this technology and hoped that DTMB-A standard’s industrialization could be realized as soon as possible. Moreover, they expected that DTVNEL(Beijing) could do more contribution for domestic terrestrial digital television development.
