ABSTRACT:
A method and apparatus for video conferencing is disclosed. According to one embodiment, a Universal Serial Bus (USB) enabled digital video camera may output an encoded information stream. The USB-enabled digital video camera including an encoder may compress image data received by the USB-enabled digital video camera during a real-time video conference to produce the encoded information stream in which no frame of the encoded information stream may depend on a previous frame by performing intra frame encoding. A computer system coupled to the USB-enabled digital video camera via a USB may be used to decode the encoded information stream and to transmit the image data to one or more other computer systems as part of a video conferencing data stream.
