Abstract
For many real-time visual communication applications such as video telephony, the transmission channel used is typically constant bit rate (e.g. PSTN). Under this circumstance, the encoder´s output bit-rate must be regulated to meet the transmission bandwidth in order to guarantee a constant frame rate and delay. We propose a new predictive rate control scheme based on the activity of the scene to be coded for H.263 encoder
