      Cutting Through – Pixel Perfect Excuse Part 1

      What is the truth?

      Crestron has just released a firmware update for their NVX that claims to end the 1G vs 10G debate. Pixel perfect technology appears to be a 20:1 proprietary JPEG2000 based codec that only addresses static images. This does not solve the NVX’s two frame latency, motion quality issues, or power consumption. Crestron’s firmware update does not end the 1G vs 10G debate.

      Cutting Through – 4K 60 4:4:4

      What is the truth?

      A 1Gbps network simply cannot transport 4K 60 4:4:4 content without a loss of quality. 1G solutions utilize a very high 20:1 compression leading to image quality issues, frame stuttering, and higher latencies of 30ms and more.

      10G at 4K60 4:4:4 is a 1.3:1 lossless compression with a maximum latency of 0.1 milliseconds. When the bandwidth is 4K60 4:2:0 or below, SDVoE over 10G Ethernet has no compression and only 0.022 milliseconds of latency. Medical, broadcast, and high-quality usage will have issues with the 1G results which will be unpredictable when it occurs. Even HDR can be affected if the original content is altered.

      Cutting Through – Crestron NVX EMI Test

      What is the truth?

      While higher bandwidth networks are more susceptible to interference, gimmicks like wrapping network cables around motor based devices such as a coffee grinder does nothing more than entertain and confuse. A properly installed network infrastructure should neverbe located near any type of EMI or ESD interference, regardless whether the network is 1Gbps or 10Gbps. The NVX relies on forward error correction and retries to mitigate network interference – even those techniques will eventually fail based on the severity and longevity of the interference.

      The fact is, if you have extreme EMI or ESD interference on your network – any network – you have the potential to impact any data or service running on that network. This is not only a matter of best practice installation methods, but also electrical standards.

      Cutting Through – Correcting Crestron’s Pricing Claim

      What is the truth?

      Does an Aurora IPX 10Gbps system cost more than 3 times a comparable Crestron NVX system? The answer is NO! In fact, an Aurora system can actually come in at a lower cost. So why the discrepancy?

      Crestron’s document omitted the cost of power supplies, for one. But the biggest problem was that the Crestron document listed a 32-port 10Gbps switch at $40,000! We are not sure why anyone would A) need a 32-port switch for a 9 unit AV over IP system, or B) pay $40,000 for that switch.

      In the real world, manufacturers like Netgear make 10Gbps switches at a much lower price point. Take for example the Netgear XS712Tv2 12-port 10Gbps switch with an MSRP of $1,712. Not quite the grossly inflated $40,000 that Crestron claims. Even better, the M4300 series switches from Netgear are priced at $100 per port, and are pre-configured to work out of the box with SDVoE systems, no configuration required!

      When you add up the real figures, the Aurora Aurora IPX solution is comparable in price or even less than an NVX system, plus you get all the added benefits and future upgradability of a 10Gbps AV over IP system and network. If you really wanted to compare apples to apples, compare Auroras 1Gbps VLX system to the NVX. You will find that the VLX comes in at about half the cost of NVX!

      Cutting Through – VLX Setup vs. Crestron’s Claim

      What is the truth?

      The Aurora VLX is simple to setup. Thousands of units have been successfully deployed across numerous installations, running 24/7. Our exclusive Rapid Deployment Tool allows for quick and simple setup for large scale systems using a standard spreadsheet. The IPBaseT Manager software provides a familiar drag-and-drop routing interface, along with many other tools. And finally, our control protocol is simple, and allows for dedicated RS232 and IR over IP ports at each endpoint that can be used from any control system supporting Telnet.
