    Solution background introduction:

    As the first platform for people to obtain information, TV is irreplaceable. However, traditional TV can only be passively received, can not choose to watch, and the definition is not high; in addition, missed programs cannot be returned to watch. The existence of various problems has forced people to continuously explore new technologies in order to solve the various disadvantages of traditional television.

    In recent years, with the advent of the Internet, network accessories have also emerged. One of them is Internet TV (ie, IPTV), which uses the IP network as the transmission medium. This Internet-born thing has also developed rapidly with the broadband network. IPTV uses televisions, personal computers, and handheld devices as display terminals and accesses broadband networks through set-top boxes or computers to implement services such as digital television, time-shift television, and interactive television. The emergence of Internet TV has brought a new way of watching TV. It has changed the passive TV viewing mode in the past, and realized that the TV can be watched on demand and stopped on demand.

    The emergence of Internet TV has boosted the pace of information construction. While enriching network applications, it has saved costs and improved efficiency. Today, thirty years after reform and opening up, it is a wonderful interpretation of digital media's changing lives, and it must also Will completely change people's traditional habits of access to information.
