The search continues for a cost effective low maintenance Skype meeting room solution, having initially trialled the LG 42LV3730 with skype camera AN-VC300 we found the technology to be wanting; and in the end connected a PC to the screen for the majority of calls.
“none of the current generation of Skype-enabled TVs support Skype Group Video Calling. If somebody in your contacts starts a group video call on a computer and then invites the TV onto the call you can take part as an audio-only attendee.”
We now have a new contender for Skype in our meeting rooms with the introduction of the Logitech TV Cam HD.
Logitech TV Cam HD
The Logitech TV Cam HD plugs right into your big screen HDMI port and starts working — on any brand TV with HDMI. Built with you in mind, the Logitech TV Cam HD clip-on design makes it easy to securely mount on top of any HDTV, or you can simply mount it to the wall. All you need is an available HDMI port and an Internet connection through Wi-Fi® or Ethernet. Everything else is already in the box! 
The Logitech TV Cam HD is a wide angle camera that comes with Skype pre-installed. If the TV model you have does not support Skype, simply connect the camera to your HD television and to the internet, and you’re ready to go. 
Although pretty soon we start hitting the limits that we discovered with the Skype on the IP TV setup – problems with Group calls;
Group calling with audio only (you can join the group call, but not initiate one) 
Because in our environment ‘all inputs belong to VGA‘ I need to convert the HDMI to VGA. With our AppleTV installs I have been using the Jaycar HDMI to VGA Converter (AC1638) so this was my first choice and nada, no video signal, it doesn’t work. Move across to the Jaycar HDMI to VGA/Component and LR Analogue Audio Converter (AC1605) and we’re up and running. The resolution passed through to the screen is 1280×720/60. As it works out the unit is delivering audio via HDMI so you will need the audio output from the more expensive converter anyway.
The next trick is that the unit has to get an IP via DHCP before you can get to the settings, probably not an issue for the home user – not the best in a corporate setting when a DHCP registration may take some time and manually coding the IP is a useful workaround.
Once connected to the network the unit checked for updates, I accepted the software update so we are running the latest version (v.1.6.206).
