The ProHD Report

Fig. 19. The graph shows that the full HD quality of the ATSC transmission really only takes advantage of about 50% of the total available Pixels/Second in a RGB native 1280x720p60 display. It really confirms the viewing tests that 1280x720 resolution displays are more than sufficient to provide the large majority of home viewers with the best possible perceived HD viewing experience, whether the source is 720p or 1080i.

The JVC ProHD Camcorder, with native acquisition and delivery to TV station matching the full ATSC bandwidth (1280x720p60) and 4:2:0 pixel for pixel, will not degrade the pixels/sec benchmark from a pixel conversion point of view, delivering 83 million pixels/sec, although we must recognize that the 1/3-inch imager block and the ProHD CODEC will not reach the HD image quality or accuracy of the uncompressed HD studio camera output.

A Panasonic DVCPRO-HD Camcorder, delivering to the TV station through the DVCPRO-HD format 960x720p60, requires large amounts of pixel conversions due to the 960 luminance and 480 chrominance horizontal bandwidth limitations:

960x720p60 x 2 = 83 million pixels/sec (no Kell/I reduction, progressive) Luminance 960x720p60 = 41.5 million pixels/sec

Chrominance 480x720p60 x 2 = 41.5 million pixels/sec
