Application Of 4G Technology In TV

4G technology is known as the fourth generation of communication technology,the use of 4G technology can be used to obtain a more efficient and faster wireless transmission service than the previous generation of communication technology.Mobile terminal devices for peer-to-peer networking(P2P)HD video streaming service with 4G technology has become possible.In this paper,the wireless transmission technology,P2 P sharing technology,mobile user terminal state management technology and orthogonal frequency division multiplexing(OFDM),IP based core network technology and so on are introduced in detail in this paper.This paper analyzes and studies the 4G live system,and realizes the work of collecting and downloading the video with the mobile terminal,such as the news gathering equipment and so on in the 4G environment.The index server in the 4G live system realizes the index of the video recording of the news gathering equipment,and the video related information is effectively managed.The system state server realizes the distributed management of the news gathering and publishing and downloading video.Data server provides a platform for the video resource sharing to the news gathering and mobile terminal equipment.In the paper,the design of the 4G system and the method of solving the function are also mentioned.The problems encountered in the development of the system can be solved by repeated practice.After the completion of the system development,we have experienced the continuous testing and debugging,and the results of the different operators are reflected in this paper.The function of the 4G system is verified,the system is running well,and the basic function is stable.Under the environment of 4G technology,the bandwidth of the system can be downloaded and downloaded.The system can ensure the video playback is clear and smooth,and the feasibility of the system is also demonstrated.4G direct broadcast system has fully played the technology advantage of 4G technology,and solves the problem of "wireless transmission" which is difficult to solve.So that the radio and television can be used to transmit video signal in real time.
