MOBILE VIDEO TRANSMISSION COMPLEX Russian patent published in 2017 - IPC H04N5/28 H04N7/16 H04H60/59 

FIELD: physics.

SUBSTANCE: mobile video transmission complex is proposed, comprising: a transmitting antenna system, a transmitter, a signal processing unit with cable inputs including a laptop computer, an information stream coder, a data flow multiplexing unit, a cross board, a modulator, an amplifier with a control unit, a receiving antenna system connected through an active signal divider with receivers, a squarer/multiviewer and a monitor. The complex is equipped with video cameras, the outputs of which are connected to the inputs of a wireless transmission system including a signal processing unit and a power amplifying unit. The signal processing unit contains two modules of 2-channel encoders, a multiplexer, a cross-board and a modulator, each 2-channel encoder module connects two sources of digital video signal via the HD/SD SDI or HDMI interface, signal coding according to the standard MPEG4 AVC and general stream transfer via the ASI interface through the cross-board to the DVB-T modulator control module. In addition, the signal processing unit is equipped with four HDMI connectors, four BNC connectors for connecting HDSDI cameras, and the first television signal processing channel is provided with an additional external analog audio signal input for connecting the service signals. The wireless multi-channel system for receiving and displaying video and audio signals is equipped with two receiving antennas with masts, an active divider, four DVB-T signals, a squarer/ multiviewer for simultaneous displaying video and audio information from several sources, a video audio monitor with an audio channel, an external connection panel, a power supply distributor.

EFFECT: expanding the functionality.
