With the market moving towards switching and extending videos in large rooms using HDBaseT, a newer technology (Crestron NVX) emerged recently which will change the way you extend audio and video in large facilities like meeting rooms, conference rooms, ballrooms, etc… Instead of playing with the infrastructure of the rooms, the new technology requires the existing 1 Gigabit and a DM-NVX device infrastructure to be able to display video from a source on the same network.
Advantages of using Crestron DM-NVX over HDBaseT
1. DM-NVX requires only a 1Gigabit network switch
No need to use a special audio/video matrix to switch the signal between the displays. With installing the Crestron NVX as an endpoint next to the display and another next to the source, both devices are connected with just a 1 Gigabit switch which can be found on the shelve. This setup is sufficient to deliver the latest top quality picture from the source to the display.
2. Fewer cables and equipment in the rack.
The only cables and equipment used in this setup is the regular Cat5e cable, a 1 Gigabit switch and DM-NVX devices. On the other hand, HDBaseT setup requires an intermediate system. Sometimes this intermediate system is a combination of transmitters, receivers, matrix and other cables (HDMI cables, power cables, network cables). Excessive cables causes interference within which cause disturbance to the data transmitted around as such in point 3.
3. No flickering due to electrostatic interference

4- Anytime expand the system
With the DM-NVX system, adding another source or display doesn’t require a major change in the rack. Guess what? no equipment is in the AV rack. Expanding the system is easily done with only adding the required endpoint to the existing network switch
5- Video scaling available for every display
Crestron NVX can transport media resolutions of up to 4K60 HDR. Even if your displays are 1080p, displaying a 4K source can easily be scaled to be displayed best at the existing displays. once you upgrade the display to higher resolution, higher resolution is displayed. Crestron DM NVX covers all resolutions and scales the image to the display.
6- No latency
The latency in the DM-NVX is similar to an HDBaseT system. You can check the demo in the following video. Hint try to pause the video to compare the latency on the display screens in the video
7- The media is transported throughout the network
No need to pull extra cables or adjust the system to transport video to an alternative location. Since the video is on the network, you can transport it anywhere within that network.
8- Very fast video switching
Crestron is famous for its reliable systems and so is the video switching.
9- USB and Audio Routing
USB 2.0 can be rerouted to anywhere in the network and same is the audio which can be routed the same Crestron NVX.
10- Soon integration with Dante
Dante is the audio over the network. With such integration, no need to connect audio by audio cables, instead the audio is routed to the DSP by the network. Moreover, with the Dante integration, the audio extract within the DM NVX devices can be processed using The Dante DSP.
HDBaseT advantages over DM-NVX
We can’t neglect the HDBaseT solution is a simple solution for simply extending Media. We should still see the technology in use because extending media with this technology is just plug and play. This technology could also be recommended in a simple video distribution system, however when the system design goes complex, it will be recommended to use the DM-NVX technology instead.
Many previous installations we check and repaired were cost saved by installing video matrix and extenders, instead of using modular Digital Media switchers that caused errors in the system. Click here to open the article
