Retrospective: Historical Briefs from Past Issues

The May 2001 Journal published in: “On Scanning Format and MPEG-2 Coding Efficiency” by E. B. Bellers and G. de Haan. “The traditional analog video broadcast standard is an interlaced format. Interlace was included in the standards for television broadcasting for very good reasons; however, with the introduction of digital video broadcast (MPEG-2), we should reconsider the use of interlace as part of a digital video chain. Moreover, video format conversion, in general, may also require reconsideration as it can be performed either at the studio end (transmitter side) or at the receiver end (television set). This paper examines the efficiency of MPEG-2 coding for interlaced and progressive video and also compares de-interlacing and picture-rate up conversion before and after coding. We found receiver side de-interlacing and picturerate up conversion, (i.e., after coding, to give better image quality at a given data rate.” For the full article, see: https://tinyurl.com/yc8cz9j3
