Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. One or more embodiments of the present invention are illustrated in the accompanying drawings to provide a more accurate and thorough understanding of the disclosed embodiments. It should be understood, however, that the present invention may be embodied in many different forms and is not limited to the embodiments described below.

The video system includes a video camera 10, a switchbox 12, a recorder 14, a monitor 16, a real-time packaging station 18, and a wireless communicator 20.

The camera 10 is used for shooting a live picture to be directly relayed, and may be a professional photographic device, or a portable electronic product with a photographic function, such as a mobile phone, a tablet, and the like. Preferably, to ensure the comprehensiveness of the direct broadcasting picture, there are usually a plurality of cameras 10, such as eight cameras shown in the figure. The cameras 10 differ in position and angle. The camera 10 can transmit the images taken by the camera to the switching station 12 by wireless transmission or wired transmission. Preferably, to facilitate electrical connection between the various components, all signal sources are connected to the system via jumper panels.

The switching station 12 performs switching, encoding, embedding, and the like on the input signal, and outputs a PGM SDI signal to the back-end live wrapping station 18. Due to the requirement of meeting the requirement of multi-machine position and multi-angle direct broadcasting content, the switching station 12 is preferably capable of supporting 4-channel HDMI and 4-channel SDI high definition signals, and simultaneously supporting XLR analog audio signal input, so as to complete the function of system audio embedding. In one embodiment, the switching station 12 employs an ATEM Television Studio HD of blackmac Design. In addition, considering that the internal space of the vehicle body is relatively limited, the control panel of the switching console 12 may be a tablet or a thin notebook computer, such as a Surface Pro 7.

The recorder 14 is used for recording and storing the captured images, preferably supporting SDI ultra high definition input. In one embodiment, the recorder 14 uses a HyperDeck Studio Mini of Blackmagic Design, and records and plays back using two high-speed SD cards, with the highest recordable ProRes 4444.

The monitor 16 is used for monitoring the shot pictures, and preferably three high-definition portable screens are used, namely a director, a disc-jockey, and a real-time packaged monitoring operation screen. The operation screen can utilize the interface of sunshading board to fix, makes things convenient for the staff on the front seat to look over, can normally fold when not using moreover and can not destroy vehicle structure. The operation screen also can be fixed in the back of seat, if fix on the bearing structure who acts on the headrest, can make things convenient for the staff on the back row seat to look over like this, also makes things convenient for the reason line simultaneously. The monitor 16 is fixed to the vehicle body at a proper position, so that the operator can feel comfortable for a long time.

The real-time packing station 18 superimposes the information such as the packing, caption bar, name bar and the like of the signals transmitted by the switching station 12 and then pushes the streams to the aggregation encoder in a mode of SDI output. In one embodiment, the real-time packaging station 18 employs a vMix high-performance real-time packaging workstation.

The wireless communicator 20 is used for remote communication of the staff, and in one embodiment, a mammoth 450T wireless communication system is adopted, which supports up to 8 calls and a communication distance of 450 meters, and covers communication work of all kinds of workers.

The audio system is used for processing sound signals, a sound console 22 is selected in a specific embodiment, 16 audio signals can be input at most, and functions of a compressor, reverberation, noise reduction and the like are built in the audio system. Preferably, a 3.5mm headphone jack can be reserved under each operator seat to monitor the final output sound in real time. The console 22 can be controlled by a mobile phone, a tablet, a computer, etc., and for example, iPad can be used as its control panel.

The encoding system streams the signal codes output by the real-time packing station 18 to a playout platform, preferably a 5G +4G aggregate encoding system. In one embodiment, it is composed of a 5G CPE 24 (e.g., 5G CPE Pro2) and a 4G aggregate encoder 26 (e.g., high vision T80). The 5G CPE provides the whole vehicle network and router support, and converts the 5G network into a wired network signal to the T80 for 5G +4G aggregation function. In addition, the operation control of the switching station 12, the recorder/player 14, and the like can be performed through WiFi or a wired network owned by the 5G CPE.

The power system is preferably an outdoor power supply with power not lower than 300 watts, and can support outdoor live broadcast for 3-4 hours. In addition, a UPS uninterrupted power supply and a generator can be additionally arranged to supply power for a longer time and more stably. The electric power system is independently arranged, so that the damage to the vehicle with the storage battery caused by long-time use is avoided.
