Embodiment Construction

[0024] The present invention utilizes the wireless network to transmit the request and control information, utilizes the broadband wired network to transmit the video information, according to the attached figure 1 The specific steps shown are:

[0025] ① The mobile data communication terminal 101 at the user end obtains the electronic program guide EPG information from the application server 301 through the wireless data communication network 201;

[0026] ② The mobile data communication terminal 101 at the user end sends a video service request VR to the application server 301 through the wireless data communication network 201;

[0027] ③ The application server 301 sends the video service request VR to the broadcast control server 302 through the IP network using the TCP / IP protocol;

[0028] ④ After the broadcast control server 302 receives the video service request VR from 301, it selects a suitable video server 401-n through the IP network to start the video service con...

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.

Description

technical field [0001] The invention belongs to the technical fields of communication and television, in particular to a video service system. Background technique [0002] The end-to-end video service system for large-scale commercialization has always been the goal that people dream of, and it is also the direction of the development of broadcasting and television systems. Since the 1990s, with the development of computer host performance and network technology, the theoretical research and implementation technology of video service systems have made some progress, and various video service systems have emerged, such as video on demand. VOD technology has been applied in a certain range in the homogeneous network. However, due to the large initial investment, high operating cost and relatively backward technical means of these video service systems, it has been difficult to obtain large-scale popularization and promotion for a long time: [0003] a) Solution based on comp...
