NGCodec and Celeno to demo low-latency, wireless video transmission for VR with 250:1 compression at NAB in Las Vegas

Basic problem: When you’re fighting aliens to save the galaxy wearing your VR headset, having a wired tether to pump the video to your headset is really going to crimp your style. Spin around to blast that battle droid sneaking up on you from behind is just as likely to garrote you as save your neck. What to do? How will you successfully save the galaxy?

 

Well, NGCodec and Celeno Communications have a demo for you in the NGCodec booth (N2635SP-A) at NAB in the Las Vegas Convention Center next week. Combine NGCodec’s low-latency H.265/HEVC “RealityCodec” video coder/decoder IP with Celeno’s 5GHz 802.11ac WiFi connection and you have a high-definition (2160x1200), high-frame-rate (90 frames/sec) wireless video connection over a 15Mbps wireless channel. This demo uses a 250:1 video compression setting to fit the video into the 15Mbps channel.

 

In the demo, a RealityCodec hardware instance in a Xilinx Virtex UltraScale+ VU9P FPGA on a PCIe board plugged into a PC running Windows 10 compresses generated video in real time. The PC sends the compressed, 15Mbps video stream to a Celeno 802.11ac WiFi radio, which transmits the video over a standard 5GHz 802.11ac WiFi connection. Another Celeno WiFi radio receives the compressed video stream and sends it to a second RealityCodec for decoding. The decoder hardware is instantiated in a relatively small Xilinx Kintex-7 325T FPGA. The decoded video stream feeding the VR goggles requires 6Gbps of bandwidth, which is why you want to compress it for RF transmission.

 

Of course, if you’re going to polish off the aliens quickly, you really need that low compression latency. Otherwise, you’re dead meat and the galaxy’s lost. A bad day all around.
