Embodiment Construction

[0012] The present invention will be further explained below in conjunction with the drawings.

[0013] Such as figure 1 As shown, a ground live broadcast vehicle is equipped with four cameras with adjustable shooting angles on the roof of the broadcast vehicle, and the signal output end of each camera is connected to the on-board hard disk 1 located in the broadcast vehicle. The data captured by the camera can be saved on the vehicle hard disk with four-channel CIF video and audio recording. The vehicle-mounted hard disk is connected to the video signal compressor 2, and the output end of the video compressor 2 is connected to the wireless communication system 3. The wireless communication system uses a 4G communication module. The video compressor reads the video data on the on-board hard disk and then compresses it and sends it to the data processing center through the 4G communication module. It realizes the signal transmission through the current mature 4G network, avoids r...

Abstract

The invention discloses a ground on-site outside broadcast vehicle. Video signals captured by vehicle-mounted cameras can be saved on a vehicle-mounted hard drive via CIF video / audio recording, and the collected signals are broadcast relative to satellite channels of the prior art. The ground on-site outside broadcast vehicle of the invention can provide a channel of 4G network transmission on-site video signals, can avoid the rental of satellite channels, and greatly reduces the cost of on-site video outside broadcast. An unmanned remote control aircraft controller arranged in the outside broadcast vehicle can facilitate remote control of unmanned shooting equipment to collect on-site video signals.

Description

Technical field [0001] The invention relates to a ground live broadcast vehicle. Background technique [0002] At present, in the field of TV broadcasting, live broadcasting is usually carried out by sending the video collected on the spot to the live broadcasting truck, and the live broadcasting truck will process the collected video and send it to the TV station processing center through the satellite communication channel. Because satellite communication costs are quite high, and satellite channels are limited, communication resources are limited. Summary of the invention [0003] The purpose of the invention: In view of the above-mentioned prior art, a ground live broadcast vehicle is proposed, which can realize the collection of live video and the transmission of the live collection signal through the network. [0004] Technical solution: In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present invention is: [0005] A grou...
