Abstract:
1. Picture transmission apparatus characterized in that said picture transmission apparatus comprises picture conversion means for converting a picture composed of a plurality of frames to a format for transmission to another apparatus to generate a converted picture on a per frame basis, picture transmission means for transmitting the converted picture generated by said picture conversion means on a per frame basis to predetermined picture receiving apparatus connected via a network, transmission time measuring means for measuring the transmission time of a converted picture transmitted from said picture transmission means on a per frame basis, transmission time predicting means for predicting the transmission time required for said picture transmission means to transmit a converted picture in a transmission-candidate frame and generating a predicted transmission time based on the transmission time of past frames measured by said transmission time measuring means, and operation timing control means for controlling the start timing for said picture conversion means to convert of a conversion-candidate frame based on the predicted transmission time of said transmission-candidate frame generated by said transmission time predicting means.
