Four IPTV system equipment providers have received clearance from the Chinese Ministry of Information Industry to supply their products in the Chinese market.
Products from UTStarcom, ZTE, Huawei and Alcatel Shanghai Bell have been checked and accepted following tests carried out in Dalian in October 2007.
The tests are targeting the application of products using home-developed AVS technology on China Netcom's pilot AVS-IPTV system, which has operated steadily for more than six months.
Overseas equipment providers did not join in the tests, because they mainly support foreign standards, such as MEPG4 and H.264.
It is understood that China Netcom will only adopt AVS standard in its IPTV deployment if the tests in Dalian are successful, aimed at avoiding high patent fees from using foreign standards.
If equipment providers do not adopt AVS, they will lose the opportunity in China's market.
