1 doc.: IEEE /0090r0 Submission January 2009 Nishijo, Ochi, Miyanaga, Sai, KIT & HUSlide 1 [i-Definition TV transmission over VHTL6 system Date: Authors:

2 doc.: IEEE /0090r0 Submission January 2009 Nishijo, Ochi, Miyanaga, Sai, KIT & HUSlide 2 Abstract Show the business feasibility on VHTL6 Usage for HDTV transmission. JPEG 2000 format is chosen for its excellent error resilience tool and compression ability. We evaluate movie quality deterioration due to bit error rate.
