A TV information acquisition method, TV, background server and system

Abstract

The invention provides a television information obtaining method, a television set, a background server and a system. The method comprises that first instruction information is sent so that the background server carries out screenshot on contents played by different channels while electronic equipment carries out screenshot on contents played by a current channel; second instruction information is sent so that the background server compares characteristic information of screenshot of the electronic equipment with that of screenshots of the background server; and if a screenshot, whose characteristic information together with the characteristic information of the screenshot of the electronic equipment reaches preset conditions, exists in the screenshots of the background server, television information corresponding to the screenshot of the background server is obtained. Thus, the problems that transmission links of television information is relatively redundant and channels of STB tend to jam are solved.
