A new company, telyHD thinks it can change that equation, not only by moving video chats from the PC to the TV room, but also by offering a set of enhanced features to its product typically only possible with a computer. The $249 retail telyHD unit (available at telyhd.com, Amazon and other retailers) sits comfortably on top of an HDTV and uses the Skype service to make video calls. Once you connect the unit via an HDMI cable and sign in to Skype, your entire Skype address book is visible.
