◆The TC1 Participated actively in international standardization activities, and submitted 173 contributions to ITU-T in the whole year.(65 to SG16, 21 to SG17, 87 to FGIPTV).

1) ITU－T SG16

Six recommendations have been adopted by ITU-T SG16. Among them, Recommendation H.272 is so far China’s first full international standards in media processing in ITU, which has complete independent IPRs. Recommendation H.460.22 was put forward by China for the first time as a complement to the H.323 series. It resolves the vacancies of H.235 by helping the Call Setup Signaling being protected when the two partis are different or unknown to each other, which is of great practical significance. Three recommendations of H.248 series standard made new contributions to the consummation of the recommendations. In addition, a new study question Q.8 (Q. SAD) was established according to the proposal of China, which injects new vitality into WP3 and provide unified mechanisms for common signal detection of various audio codec. This achievement not only accelerates the development of Chinese independent IPRs and technical research, but also improves utilization efficiency of network resources and equipments.

2) ITU－T SG17

In 2006, gratifying success was achieved in the three WP in ITU-T SG17 (open systems technology (WP1), Telecommunication Security (WP2), language and telecommunication software (WP3)): China continued to lead the research on X.fcs " technology framework of email Anti-Spam ", and started to lead the research on "Technical requirements in Anti-Spam "
