A system comprising a plurality of points of access deployed in venue having a crowd area located next to an event happening area, each one of the plurality of points of access comprising an optical transmitter adapted to broadcast an encoded media stream in light emissions, a plurality of portable optical receiver units, each having: a connector adapted to be electrically connected to one of a plurality of client devices, an optical receiver adapted to capture the light emissions, and a controller adapted to convert the light emissions into a digital stream forwarded via the connector to a respective client device of the plurality of client devices to allow a presentation of the digital stream on a display of the respective client device by an application executed on the respective client device.

Disclosed is a data transmission system having a transmitter and a receiver. The transmitter encodes external input signals to acquire coded transmission data transmitted in multiple paths with different frequency band, and then transmits them to respective receiver; and the receiver performs data fusion on the received transmission signals to acquire coded received data, and decodes it to acquire and output the decoded data. In conclusion, since the received signals are split into a plurality of transmission signals of different frequency bands by the transmitter and the signals are fused in the receiver, the signals are not susceptible to the same frequency interference during transmission, improving the anti-interference of the data transmission system, realizing high-reliability transmission at low cost or in a complex wireless environment, also expanding the applications of the data transmission system.
