Abstract	Throughout the broadcasting chain 4:2:2 chroma format is widely used even if some parts of the chain require other formats (4:2:0 or 4:4:4). This paper presents an approach to coding video content in 4:2:2 chroma format using resampling of chroma samples. All subsequent video coding operations are then carried out at the new chroma format. The choice of filter for resampling the reconstructed video signal is sent to the decoder in the compressed bit-stream. This paper investigates choices of resampling filters and coding parameters associated with the proposed approach with a goal to minimise conversion losses. Coding performance of possible solutions are reported for two reversible resampling filter pairs when applied in the emerging HEVC video coding standard.
