Abstract
The invention consists of the mobile terminal, the wireless communication application server, the display control server and the video server. The invention uses wireless network to transmit control signal and uses wired network to transmit video signal. The invention overcomes disadvantage that is the narrow bandwidth of mobile communication system cannot adapt the wideband video transmission. It also overcomes technical and cost problem for implementing up-stream transmission in the user active video service system based on cable TV HFC network. The implementation of wideband video service system doesn't need to make bi-direction reconstruction and considers the influence of feedback noise of HFC network to performance of system.
