Abstract
A method of transmitting video data comprising: establishing a bidirectional video channel between a first terminal and a second terminal in a packet-based communication network; beginning a live, face-to-face video call over the established channel by generating first video data from a video camera of the first terminal, transmitting the first video data to the second terminal for display on a screen of the second terminal, receiving second video data generated from a video camera of the second terminal, and displaying the second video data on a screen of the first terminal; generating third video data at the first terminal from a source other than the video camera of the first terminal; receiving a user selection at the first terminal; and in response to the user selection, transmitting the third video data to the second user over the established channel of the packet-based communication network.
