HOLDING THE HDMI HANDSHAKE, AND WHY THAT’S IMPORTANT
Posted on Monday, May 4, 2020
HOLDING THE HDMI HANDSHAKE, AND WHY THAT’S IMPORTANT

In video distribution systems that use HDMI as the delivery method, many things can go wrong to take away a clear picture. One of the most notorious errors that can happen in this pathway is with the HDMI "Handshake." The HDMI Handshake is the process of both the source (streaming device, UHD blu-ray, gaming console) and the sink (television, projector, monitor) recognizing each other and determining that they are both authorized to transport the high bandwidth HDMI signal. This process is continuously repeated while the signal passes through the HDMI pathway.

As integrators introduce additional products between the source and the sink, such as AVR's, HDMI extenders, HDMI switchers, repeaters, or any other video processors, that can affect the HDMI signal. The more items in-between the source and the sink, the more opportunities for something to fail. Dropped picture, flashing screen, no image, the dreaded "No Signal" displays on the tv; these are all things that HDMI handshake problems can cause, especially when trying to switch between two different video sources. Today's integrators need to be aware of these problems and be able to manage them, ensuring that when they leave a site, they won't have to return the next day to "fix" the distribution system.

THE SOLUTION?

Holding the HDMI Handshake.

When you switch your distribution system from one source to another, it needs to re-authenticate the HDMI Handshake, ensuring that the signals passing along the infrastructure are authorized. That switching takes time; now, our whole system needs to verify the handshake process. This stops any signal from getting on the display or projector, often putting up the "No Signal" screen built into the displays.

By holding that handshake in-between the distribution infrastructure and the display, you can increase switching speeds, stabilize your distribution, and deliver a superior solution for the end-user. But how would you do that?!?!?!?! It's impossible???????

Not any more...

Introducing the AC-SC2-AUHD and the AC-EX70-SC2-R, a one input, one output device that was made to be the integrator's new best friend. These products can hold the handshake with the display, projector or monitor, allowing you to increase switching times, stabilize your system when switching and deliver an extremely stable install for your customer.
