Television system video conferencing is described. In an embodiment, a television-based client device receives program content from a content provider via an IP-based network to display a program for viewing. The client device generates video conference data to participate in a video conference session with one or more additional television-based client devices over the IP-based network. The client device communicates the video conference data to the content provider for association and distribution to the additional client devices, and receives incoming video conference data over a virtual channel designated for the video conference session. The incoming video conference data is hosted by the one or more additional client devices and is received from the content provider via the IP-based network. The client device then renders the incoming video conference data for television system video conferencing.
