Abstract: For high-definition satellite newsgathering (HD-SNG) applications, 4:2:0 video codecs are widely used; however, there is one major draw-back to 4:2:0 chroma sampling. When two or more 4:2:0 codecs are concatenated, the chroma component gradually becomes blurred because the codecs are usually connected via high-definition serial digital interface (HD-SDI) (a 4:2:2 interconnect) resulting in upsampling and downsampling of the chroma component. To solve this problem, a new chroma downsampling and upsampling filter set has been designated for the 4:2:0 codec, whereby chroma degradation is completely suppressed after several stages of concatenation. This paper explains the features of the 4:2:2/4:2:0 perfect reconstruction filter set and discusses its application for HD-SNG.
