Rate-Distortion Control in Wavelet-Based Video Compression Systems With Memory Restriction

Video transmission systems over wired/wireless channels are widely used in many spheres of the everyday life. However, such systems still have high memory and computational requirements. This paper presents algorithm for wavelet-based video compression in video transmission systems with the constraint memory budget that is insufficient to store a single video frame. The proposed algorithm of rate-distortion control provides with the equal acceptable level of visual quality over the whole frame taking into consideration the channel throughput and transmitter/receiver memory constraints.
