Abstract:
A portable video conference system supporting a network-based video conference, the system comprising:a processor accessing a local non-volatile memory, the processor coupled to a wireless data capture interface, a video camera, a video display interface, an audio input device, an audio output interface, and a network interface; a portable wireless device coupled to the wireless data capture interface, the portable wireless device adapted to capture writing or erasing from a writing surface; wherein the local non-volatile memory comprises: a program code segment for repeatedly receiving from the network interface an external audio-video stream to create a received video stream presented to the video display interface and to create a received audio stream presented to the audio output interface; a program code segment for receiving a local video stream from the video camera and receiving a local audio stream from the audio input device and receiving the wireless data capture state from the wireless data capture interface to create a local audio video data stream; a program code segment for sending the local audio video data stream to the network interface; and wherein the local instruction processor executes the program code segment residing in local non-volatile memory for receiving the local video stream from the video camera and receiving the local audio stream from the audio input device and receiving the wireless capture data capture state from the wireless data capture interface to create the local audio video data stream.
