广播电视单向网络下互动点播的实现方法研究和设计

Research and Design of Interactive VOD on Broadcast Television One-way Network

提出了一种利用智能手机与互动点播系统交互,通过手机扫电视屏幕二维码,获取电视机顶盒所在网络位置等信息,由手机代理机顶盒向互动点播系统发请求,从而完成互动点播功能的一种方法。该方法是通过移动通信网络与数字电视广播网结合实现机顶盒互动点播的功能,弥补了必须在现有数字电视广播网络中建设双向网络才能实现互动点播功能的缺欠。它融合了手机与电视各自的优势,即在手机屏幕操控,在电视屏幕显示,从而提升了用户的体验。

A method of using smart phone as set-top box agent to interact with VOD back-office system to get VOD service done is descripted in this paper.The key functions played by mobile app includes scanning QR code shown on TV,extracting useful information like STB location in DTV network,etc.,and sending command to VOD back-office system on behalf of STB.This method uses both DTV network and mobile telecom network in one VOD session to get the service done,which makes it not necessary to construct a two-way DTV network any more for VOD service.This method makes full use of the advantages of the two network terminals,mobile phone used as an interactive controller,and TV set as a display,which enhances the user experience greatly.
