A device equipped with a camera and microphone includes the capability to send and receive video calls through a delivery system or other communications networks. In response to detection of the occurrence of a video call event or triggering event, a video program is automatically paused. In response to an incoming video phone call, message, web page, or other video communications information, the system pauses the video program and indicates the occurrence of the communications event. The system also buffers the video program while paused, providing a user with replay capability. Alternatively, the system waits for a triggering event in order to pause the video program. The device may also include features for caller identification of video calls and dual display of video programs and video calls (e.g., picture in picture). A hardware upgrade for adding video call functionality to a device is also disclosed.
