Recommendation on the Strategy of Using the Different Scanning Formats

The purpose of this recommendation is to update the Recommendation on Scanning Formats formulated by the RACE Image Communication Project Line 4 in January 1994. This update takes into account the studies performed in WP2 within the framework of the Scanning Formats Extension. This paper also discusses the strategy to follow in order to adopt a progressive format for the coding of digital television. The work performed within the framework of the RACE 2110 HAMLET Extension on Scanning Formats, leads to the following statements : 1. Interlaced format has been chosen in the early years of television considering it was one of the most interesting solution to achieve compression with regard to the available technology [1]. 2. The improved quality of today's television sources and displays make the viewers less tolerant of the defects of the interlaced format (i.e. interline flicker, line crawling and field aliasing), especially for large displays, close viewing distance and high brightnes..
