Design And Implementation Of An Information Auto Collection System In IPTV

With the recent development of television technology and the promotion of networks integration, TV technology is more and more digital, high definition, personalized direction, interacting with the terminal continuously strengthened. To access WEB information through TV terminal, is becoming more and more interested in options for home users.Since the different display formats and resolution, TV terminal can't display the application directly from WEB but only through the conversion method. In general it is managed by professional IPTV system solution providers or system integrators to provide software system, through which the system captures the original information on the WEB site automatically, parses it, and converts into a standard TV format.Information Collection System was first appeared and used in the search engines.
