Abstract:
The moving picture real-time communications terminal comprises: an input unit which inputs an RGB video image signal; a conversion unit which converts the RGB video image signal into a YUV video image signal including Y, U and V video image signals; a compression and encoding unit which digitally converts the YUV video image signal outputted from the conversion unit into moving picture data, and compresses and encodes the moving picture data; a communications unit which sends and receives the moving picture data compressed and encoded by the compression and encoding unit, in real time, to and from a communications terminal of another party connected through a network; a bandwidth estimation unit which estimates change in a bandwidth of the network; a switching circuit which connects and disconnects output paths of the U and V video image signals from the conversion unit to the compression and encoding unit; and a switching control unit which disconnects the output paths of the U and V video image signals by operating the switching circuit, in response to the change in the bandwidth estimated by the bandwidth estimation unit, wherein the compression and encoding unit increases a bit rate of compression and encoding of the Y signal, in accordance with disconnection of the output paths of the U and V video image signals.
