WHDI wireless transmission system

SDI and HDMI, 150 meters


S-4915 is the broadcast industry wireless system, includes an S-4915T transmitter and an S-4915R receiver, with WHDI (OFDM) technology, supports uncompressed 3G/HD/SD-SDI and HDMI wirelessly transmitted in 150 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-4915T supports:
3G/HD/SD-SDI input ×1
HDMI input ×1
The receiver S-4915R supports:
3G/HD/SD-SDI output ×1
HDMI output x1
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.







Approx. 150m Effective Distance


Uncompressed SDI/HDMI, less than 1ms latency


In Line of Sight, the S-4915 wireless transmission system support approx. 150 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-4915 supports SDI and HDMI embedded audio (ch-1 & ch-2) transmission.




 


5.1-5.9GHz Operation Frequency


License Free


The S-4915 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-4915R receivers at the same frequency bands as the 1 S-4915T transmitter to enable the multicast mode.




Power Supply and Installation

Various DV plates optional


Both the transmitter and receiver are compact size designed, and equipped with DV plates to be powered by standard DV camera batteries. There’re following different kinds of DV plates for option:

How to Get the Best Effect of Wireless Transmission


(1) Set the antennas of S-4915T and S-4915R at different angles to extend the transmission distance and achieve stable transmission quality.
(2) Set the receiver S-4915R as high as possible.
(3) Avoid walls, trees, water and any blockage as best as you can.

How to Use Several Sets in One Location

There’re 0-9 frequency channels that can be dial switch by users.
In one location, to avoid interference to each other, we recommended:
2 sets transmission:
Set 1: channel 3
Set 2: channel 4
3 sets transmission:
Set 1: channel 3
Set 2: channel 7
Set 3: channel 4
We don’t suggest that use 4 or more sets of wireless transmission in one location.
