WHDI wireless transmission system
SDI / HDMI signal, 150 meters The S-4915 is a broadcast HD transmission system that includes the transmitter S-4915T and the receiver S-4915R. It supports wireless transmission of 3G / HD / SD-SDI at 150 m. 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
Transmitter S-4915T supports:
Receiver S-4915R supports: The receiver can output SDI and HDMI signals at the same time. If the transmitter input SDI and HDMI signals at the same time, the system will transmit SDI signal priority. Up to 150 meters effective transmission distance
SDI / HDMI uncompressed transmission, transmission delay ≤ 1 ms S-4915 wireless transmission system supports 3G / HD / SD-SDI signal without compression 150 meters effective transmission distance, transmission delay ≤ 1 ms. Embedded digital audio transmission
The S-4915 supports SDI and HDMI 2ch (ch-1 & ch-2) embedded digital audio transmission.
5.1GHz-5.9GHz wireless frequency
Multicast support
1 transmitter to multi receivers You can set several S-4914R receivers at the same frequency bands as the 1 S-4914T transmitter to enable the multicast mode.
Power Supply and Installation
Various DV plates optional
The transmitter and receiver can be 5.5 / 2.1mm circular DC interface power supply, voltage in the 6.5V-17V range. (The other can be customized according to demand 4-PIN LEMO DC interface)
The wireless system package provides:
1x S-4914T Transmitter (F/U/P/B/J/V/I/C/E DV battery mount optional) 1x S-4914R Receiver (V-mount / Gold mount optional) 3x Antennas 1x Articulating arm trestle 2x Flat screwdriver (for band configuration)
1x 5.5/2.1mm pole power adaptor
1x D-tap to 5.5/2.1mm pole cable
1x Crab clamp
1x Case
Input Video Formats S-4914T transmitter supports the following input video formats:
* Note: S-4915 does not support ARRI ALEXA 1080PSF format video transmission.
How to Get the Best Effect of Wireless Transmission
(1) the S-4915 transmitter 2 antenna is set to 90 degrees, extending the transmission distance, to achieve a stable transmission effect.
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.
Remark: all channels provide the central frequencies;
