A new partnership between Comcast and Skype will let Comcast subscribers place video calls through their television sets. The new service will require some setup -- customers will need to install Comcast-provided equipment including an adapter box, video camera, and special remote with a QWERTY keyboard that connects to the service. Using this remote, customers will be able to access Skype's instant messaging feature as well. As a bonus, the new service will integrate with Comcast's Xfinity mobile app, allowing users to switch from Skype functionality to Xfinity.
