Web conferencing and remote desktop applications require the desktop of one computer to be encoded and transmitted over a network, often the internet, to be displayed on a remote screen. Video compression techniques have to be used to achieve the low data rate needed for real time transmission. However, common video codecs like the well-known H.264/AVC and also the latest standards H.265/HEVC and VP9 are primarily optimized for natural video sequences. To this end, they work using the YCbCr color space involving 4:2:0 chrominance sub-sampling. However, this may lead to annoying artifacts with screen content, e.g. at sharp edges or text.
