The increase number of custom can't fix the problem which is caused by the decrease of ARPU. The performance have been dropped. There are some main reasons:1. The increase of number in personal computer is a big problem.2. The feeling of Broadband Value Added Business is not satisfied.Based in the problems above, The operator should focus on the requirement of becoming customers and providing wonderful Broadband Value Added Business, many operators find out that IPTV is the best way.IPTV can make people entertained significantly by transferring business content in IP network. In addition ,it uses standard coding technology of music and video. Mpeg-4 part 2 ,H.264 and AVS for video coding. MP3 and AAC for music coding. There should be a good network to transfer the IPTV content. In fact ,there is a network called CDN to make it perfect .The main function : 20% content which 80% users like are putted on ES while the rest are putted on CS. There is a VOD performance system to make the rule.Additonly,P2P technology is also the development goal of the IPTV. The communication between CDN and user is completed by the media protocol.1.
