A Comparison of Intra-Frame Codecs Considered for IMF
RheinMain University has conducted a study on the performance of intra-frame codecs currently used or considered for mastering and programme interchange applications. — The results include figures of PSNR versus bitrate, subjective assessments, transcoding and multigeneration encoding performance. The codecs under study were AVC Intra and HEVC Intra, compared to JPEG 2000 as constrained in IMF (ST 2067-20/-21). The comparison has been done for both HDTV (720p, 1080i, 1080p) and UHDTV (2160p). — The results of the comparison show that the performance JPEG 2000 is comparable to the performance of AVC and HEVC for the majority of the use cases. However, particular attention should be paid when transcoding from a block based codec into JPEG 2000 and vice versa. The paper gives recommendations how to limit transcoding loss in that case.
