We present new experimental results that complement a previous report for cases where the 4:4:4 and 4:2:0 encodings have similar compression levels. We focus especially on the \u201cband separation\u201d method previously proposed \u2013 showing such approaches to have better performance than was evident in the previous experiments. The use of this scheme can be indicated by a metadata tag such as the FPA supplemental enhancement information (SEI) message defined in the HEVC (Rec. ITU-T H.265 | ISO\/IEC 23008-2) and AVC (Rec. ITU-T H.264 | ISO\/IEC 14496-10) video coding standards, in a similar manner as has previously been used to represent the two views of stereoscopic 3D video for compatible encoding. Relative to native 4:4:4 encoding, the proposed scheme provides the advantage of compatibility with the 4:2:0 video decoding process that is likely to be available in a variety of products. The packing and unpacking procedures are of relatively low complexity, and can easily be implemented in conjunction with any 4:2:0 video codec.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We present a frame packing arrangement (FPA) scheme that enables an encoder to convey high-resolution color video (4:4:4) through a video coding system designed for subsampled color video (4:2:0).
