Abstract

In response to a request to establish video communication between a video-enabled (e.g., videophone) and non-video-enabled (e.g., cellular telephone) communication device, two-way audio communication is established between the two devices. One-way video communication is also established between a server and the video-enabled device. Video signals generated by the video-enabled device during the two-way audio communication are captured and cached within the server. The cached video signals may be subsequently retrieved and displayed by a computer terminal or video-enabled communication device.
