Either add an HDMI input on a new version of the Cisco Touch panel (i.e. Navigator 2.0) or a small box could sit between the codec and the current touch panels and have an HDMI input on it. It could leverage the ethernet cable and connection already in place to the current touch panel. A 2nd shorter ethernet could then run from this box to the touch panel.
This would enable us to no longer depend on 3rd party ethernet based HDMI content extenders for physical presentation sources. Installers rarely run a physical HDMI cable from the codec to the conference table which is why they end up using a 3rd party HDMI to ethernet Transmitter Receiver setup. This is due to needing to run longer runs than the HDMI spec allows for or not being able to fit the head of the HDMI cable through the conduit.
We understand that Cisco Proximity is one alternative that is being evaluated currently at our company. However, Proximity is not always possible due to some room's acoustics causing issue for the ultrasound and also not every device has access to the network or the proximity application. This will become even more challenging if we move our endpoints to a dedicated VLAN. Therefore, a physical HDMI input will still be needed.
