WHDI wireless transmission system SDI and HDMI, 700 meters
S-4904 is the broadcast industry wireless system, includes an S-4904T transmitter and an S-4904R receiver, with WHDI (OFDM) technology, supports uncompressed 3G/HD/SD-SDI and HDMI wirelessly transmitted in 700 meters scale, and with less than 1ms latency. The system is pure hardware connection, plug and play build-up, which is widely used in on-site shooting and director monitoring.
Input and Output
The transmitter S-4904T supports : 1 x 3G/HD/SD-SDI input, 1 x HDMI
The receiver S-4904R supports: 1 x 3G/HD/SD-SDI output, 1 x HDMI
The receiver SDI and HDMI are output simultaneously. If both SDI and HDMI is input to transmitter, the receiver will give priority to output SDI signal.
Input Video Formats
S-4904T transmitter supports the following input video formats :
The S-4904R receiver output formats are the same with input formats

Approx. 700m Effective Distance Uncompressed SDI/HDMI, less than 1ms latency
In Line of Sight, the S-4904 wireless transmission system support approx. 700 meters effective transmission distance of uncompressed 3G/HD/SD-SDI and HDMI signal, and the latency is less than 1 millisecond.
Embedded Audio Transmission
The S-4904 supports SDI and HDMI embedded audio (ch-1 & ch-2) transmission.
5.1-5.9GHz Operation Frequency License Free
The S-4904 wireless system runs at 5.1-5.9GHz License-free operation frequency. The frequency bands are user configurable and support at most 4 wireless channels in one location. The radio power is less than 63mW and will not do harm to human bodies.
Multicast support 1 transmitter to multi receivers
You can set several S-4904R receivers at the same frequency bands as the 1 S-4904T transmitter to enable the multicast mode.
Power Supply and Installation V-mount or Gold mount optional
The transmitter S-4904T is equipped with V-mount or Gold mount plates, to be easily fixed on cameras and attached with batteries. The receiver S-4904R is equipped with V-mount or Gold mount plates to be powered by batteries. Both the transmitter and receiver can also be powered via the 5.5/2.1mm pole DC in socket of 6.5-17V input.
