T-VIPS is launching its HD IP video backhaul solution based upon JPEG2000 compression, the TVG430, at NAB2006. Using JPEG2000 compression, the TVG430 reduces the bit-rate required of an HD-SDI signal from 1.485 Mb/s to between 50- and 200Mb/s.
JPEG2000 is wavelet-based and encodes each frame independently. It provides 10-bit resolution inherent in the HD-SDI format. HD television formats supported are 720p59, 1080i59, 720p50 and 1080i50.
JPEG2000, which has been selected as the standard file format for Digital Cinema, does not create blocking defects and works at full 10-bit resolution.
