The Reality of the Wide Screen

The SD (NTSC) standard aspect ratio is 4:3 (1.33:1) while the HD (ATSC) aspect ratio is 16:9 (1.78:1), presenting a formidable challenge to broadcasters as they must maintain delivery to viewers of 4:3 services while transitioning to HD providing 16:9 wide screen service. Screen Viewing Area comparison between SD 4:3 and HD 16:9 at equal Picture Height, indicating that 16:9 viewing area is 1.3x larger than 4:3 area. Of course, equal picture height is not the norm as the consumer will nearly always replace the SD TV set with a HD TV set with a much larger screen.

Fig. 1: Screen Viewing Area comparison between a 32” SD 4:3 TV set and a 56” HD 16:9 TV set, indicating that 16:9 viewing area is nearly 3x larger than the 4:3 area. Viewing distance is the same.

If we expand the exercise of Fig. 1, considering the most popular sizes of larger SD direct view TV sets (from 25” to 36”) and the most popular of the new HD TV sets (from the 37” flat LCD to the 62”+ rear projection D-ILA/DLP), we’ll find that we can use a viewing area comparison factor of 3x for the living/family

room environment with the assumption that the viewing distance has not materially changed. In other words, the average home audience screen viewing area increases 3-fold when the SD set is replaced with a HD set. (The 25” 4:3 SD set may be replaced by a 50” 16:9 HD set/monitor; the 32” SD with a 56” HD, and so on as perhaps an average.)

An important observation is that high (broadcast) quality SD originated programming up-converted to HD is nothing more than high quality SD when displayed on a HDTV set, and as such is insufficient to create a real and total HD viewing experience. (Even when using a top quality up-converter.)
