Background technique

Today, TV information is mainly disseminated by Digital Video Broadcasting (DVB) and Internet Protocol Television (IPTV). According to different transmission methods and modulation methods, DVB systems can be divided into DVB-S (Digital Video Broadcasting-Satellite, satellite digital television broadcasting) system, DVB-T (Digital Video Broadcasting-Terrestrial, terrestrial wireless digital television broadcasting) system, DVB -C (Digital Video Broadcasting-Cable, digital TV cable broadcasting) system and DVB-H (Digital Video Broadcasting-Handheld, mobile TV) system. Due to the wide coverage of the satellite and the large program capacity, the DVB-S system is mainly selected for transmission nowadays. IPTV is a system that uses a broadband network as a medium to transmit television information. It is based on the Internet Protocol (IP) transmission between networks. As long as the bandwidth is sufficient, it can be transmitted in all IP networks and can support a variety of business. IPTV can not only disseminate TV information, but also connect with all network-based platforms, such as chat, video surveillance, TV shopping, TV interaction, etc. In terms of service provision, DVB can provide almost all channels that users need; IPTV can provide services based on unicast, such as Video On Demand (Video On Demand, VOD for short), Real Video On Demand (True Video On Demand, TVOD for short), Network Video Recording (Network Recording, NPVR for short), etc., and interactive open Internet TV (Over the top TV, OTT TV for short) business. According to needs, operators can also provide channel services in the IP network. So a hybrid multi-mode set-top box appears, which can receive IPTV and DVB data at the same time.
