WHDI wireless transmission system

SDI and HDMI, 1,000 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 1,000 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:

3G/HD/SD-SDI input ×1

HDMI ×1

The receiver S-4904R supports:

3G/HD/SD-SDI output ×1

HDMI 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. 1,000m Effective Distance

Uncompressed SDI/HDMI, less than

1ms latency

In Line of Sight, the S-4904 wireless

transmission system support approx. 1,000

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.

5.47-5.85GHz Operation Frequency

License Free

The S-4904 wireless system runs at

5.47-5.85GHz 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

bepowered via the 5.5/2.1mm pole DC in

socket of 6.5-17V input.

Standard Package

The wireless system package provides:

1x S-4904T Transmitter (V-mount / Gold mount optional)

1x S-4904R Receiver (V-mount / Gold mount optional)

7x Antennas

1x Articulating arm trestle

1x Crab clamp

1x D-tap to 5.5/2.1mm pole cable

1x 5.5/2.1mm pole power adaptor

2x Flat screwdriver (for band configuration)

Input Video Formats

S-4904T transmitter supports the following input video formats:

The S-4904R receiver output formats are the same with input formats

How to Get the Best Effect of Wireless Transmission

(1) Set the antennas of S-4904T and S-4904R at different angles to extend the transmission distance and achieve stable transmission quality.
(2) Set the receiver S-4904R 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 0,
                           Set 2: channel 5
3 sets transmission: Set 1: channel 3, 
                           Set 2: channel 5, 
                           Set 3: channel 8
We don’t suggest that use 4 or more sets of wireless transmission in one location.
Frequency point in detail:

Remark: all channels provide the central frequencies;
Bandwidth is 40MHz for each channel.
