ABSTRACT:
Fuzzy rule-based control is applied to video rate control in the present invention. A basic fuzzy logic controlling apparatus using the occupancy as a fuzzy control variable is provided. Other fuzzy logic controlling apparatus is also provided: the video quality-controlled, the scene change based and the quality-monitored. The occupancy-based controlling apparatus is adopted to form a backbone scheme. The accumulative quality measure and the scene change features are then introduced to improve the video quality. The quality-monitored FRC (FRC-QM), which is controlled by both the quality factor and the scene change-based factor, is superior to the other schemes in respect of both the occupancy and the quality.
