Abstract

The invention relates to a terminal for realizing television news live broadcast through a wireless communication network. The terminal comprises a shell, wherein an analog-to-digital (A / D) conversion circuit, a video / audio coder, a transport stream (TS) multiplexer, a transmission control protocol / Internet protocol (TCP / IP) wrapper and a network card are respectively connected with a central processing unit (CPU) around the CPU in the shell; the network card is connected with the CPU through a universal serial bus (USB) interface; a video / audio signal is sent to the A / D conversion circuit from an SDI video / audio interface or analog video / audio interface; the A / D conversion circuit sends a digital video / audio signal to the video / audio coder; the video / audio signal which is subjected to compression coding generates TS data stream in the TS multiplexer; and the TS data stream is sent to the TCP / IP wrapper to be wrapped into an IP data packet. Compared with the prior art, the terminal has the advantages of simple structure, live broadcast without an outside broadcasting vehicle, low live broadcast cost, a few limitations, no time and territory limitations, obvious advantages of television media communication, quickness and convenience.

Description

technical field

[0001] The present invention relates to a terminal for realizing live broadcast of TV news by utilizing a wireless communication network, which is a news live mode terminal that transmits data streams to a media server at a designated address through a wireless communication network and the Internet, and reports on-site news at the first time. The device not only guarantees the quality of broadcast programs, but also greatly saves the high cost of using OB vans and renting satellites. Background technique

[0002] The existing live broadcasts of news, sports, and large-scale events all use OB vans, which transmit the programs back to TV stations for broadcasting through microwave or satellite channels. Although direct reports can be realized on the spot, there are also many disadvantages.

[0003] First, the cost of live broadcast equipment is high and there are many influencing factors. Live broadcast news reporters mainly use satellite OB vans or microwave...
