[REVIEW]: Tanboo EDUP EP-WD3207 Mini Wireless HD AV Transmitter & Receiver Kit
At the VRcade, we try all kinds of technologies. Each piece of tech is critical for the perfect VR experience and each must work extremely well. We have gone through a lot of devices trying to find the perfect combination of performance, size, and power. While we have a working wireless video solution, we decided to look into this little guy to see if we could get the same performance from a smaller form factor. What we discovered is that, while it does transmit video wirelessly, it introduces serious latency, something that the box claims it does NOT do.
The WHID standard offers a wonderful HD picture along with HD sound across large distances (line of sight) while maintaining strong signal strength at ultra low latency. The advertised latency is less than 1 ms. We have found this to be accurate in devices by HP. This device claims the same numbers, but nowhere on the box does it mention the WHID standard. It simply states “wi-fi”, which is technically what the WHID standard operates on, but it’s still extremely vague. If this device used WHID, why wouldn’t it proudly display it on the box?
Upon plugging the device in, the handshake process between transmitter and receiver can take anywhere from 20 seconds to a few minutes. The receiver requires 5v 2a power, or that of standard USB. Once the two devices connect, the system defaults to 720p rather than 1080. If you attempt to change the resolution to ANYTHING else, the display becomes extremely corrupted. Even switching back to 720 won’t fix it. You need to shut it down completely and start over.
The bigger problem, however, is latency. I am estimating that this thing clocks in at around 300-400ms of latency. A FAR cry from the “less than 1 ms” that the manufacturer claims.
We have two of these boxes and each one operates the same. All of the problems are identical on each. For VR applications, this device is useless. If you simply need to stream content to your TV that doesn’t require fast response times, such as video games or computer control, then this could work. However, if you are connecting this device to a TV anyway, the benefits of the small form factor are lost. Even if it was 3x the size, hiding it behind your TV wouldn’t be a problem at all.
Sound and range weren’t tested.
To be fair, the device was designed for mobile video. The transmitter has a battery in it that lasts a couple of hours. If you need to stream your phone or tablet to a TV, this should work fine, assuming you don’t want to change resolution.
