Abstract
EN Paper concerns accumulation of video-quality losses in multiple HEVC encoding and decoding cycles. The results of extensive experiments with standard video test sequences are reported. General conclusions has been drawn about relative quality losses after each cycle, as well as about total quality loss with respect to first cycle. In general, quality losses after each cycle are decreasing and total quality loss is saturating after several cycles. Total quality losses after several cycles are hardly dependent on sequence content.
