The big challenge in most video applications is to provide the highest video quality with a minimum cost of bit rate. As a result of lossy compression techniques, non optimized network conditions and other application restrictions, video quality is affected and quality of service may reduce. Video artifacts may be generated from non optimal settings and environment characteristics, causing an unpleasant visual view. The most popular video artifact is the quantization noise, generated as a result of bit rate reduction. Network packet loss, when accruing frequently, increases the video artifacts dramatically. Other artifacts like ringing noise, blocking effects, blurred images, un-sharpness and more are a result of the codec processing and in some cases, may be compensated with post processes after the decoder task.
