2024 radio and television postgraduate entrance examination knowledge point: three networks integration

Three networks integration

Three networks integration refers to the integration of existing telecommunications networks, the Internet and radio and television networks to form a unified network system. Compared with the original network, the new system implements digital communication. It is characterized by good openness and flexibility, and can provide all communication services including voice, video and data communication. After entering the information society, the scattered reality of the original network can not meet the needs of the national informatization construction, and people's communication needs are not limited to the field of voice and data communication. The communication requirements for more rapid, timely, convenient, and leisure and entertainment are growing day by day, and the concept of three networks integration came into being. The convergence of three networks will promote the development of TV industry through IPTV.
