WHDI wireless transmission

1000 meters (LOS) with Panel Receiver

S-4914P Broadcast/Film industry wireless system is based on WHDI wireless technology, 5.1-5.9GHz license free bands, with a new developed high Gain Panel Receiver, supports uncompressed 3G/HD/SD-SDI and HDMI to transmit 1000 meters (Line-of-Sight) distance, and less than 1 millisecond latency. The system is pure hardware connection, plug and play, which is widely used in director monitoring, drone, ropeway camera, steadicam etc.





 

The Transmitter

The Transmitter has 2 omni antennas, signal interfaces are:
1x 3G/HD/SD-SDI input
1x HDMI 1.3 input
(If both SDI and HDMI are connected, the system transmits SDI as priority.)
1x 6-17V DC input








Panel Receiver


The Panel Receiver adopts 14dBi high Gain Panel Antenna and build-in wireless receiver design, to set up by lighting tripod.
The Panel Receiver interfaces are:
1x 3G/HD/SD-SDI output
1x 7-36V 4pin LEMO DC input






 

 

 


1000meters Transmission

In Line-of-Sight, S-4914P supports non-compressed 3G/HD/SD-SDI and HDMI 1000 meters (3300 feet) transmission, with less than 1 millisecond latency.




Embedded Audio Transmission




S-4914P supports SDI and HDMI embedded audio (CH1&2) transmission.


 

 

 

 

 

5.1-5.9GHz Frequency



S-4914P wireless system works at 5.1-5.9GHz License-free frequency. The frequency bands are user configurable and support 3-4 pairs wireless channels to work together in one location.
The wireless output power is less than 63mW, which will not do harm to human bodies.



 

 

 


Multicast Setting


Users can set several Receivers at the same frequency point as the Transmitter, to enable 1 Transmitter to multi Receivers multicast mode.
