On video formats and coding efficiency

This paper examines the efficiency of MPEG-2 coding for interlaced and progressive video, and compares de-interlacing and picture rate up-conversion before and after coding. We found receiver side de-interlacing and picture rate up-conversion (i.e. after coding) to give better image quality at a given data rate. In contrast with some other publications, we found interlaced video coding to be better than progressive video coding for many relevant sequences, even when comparing the results on a progressive display
