The JH2000 is a hardware HDTV codec with minimal delay
and high quality transmission (50~100Mbps) of HDTV programs
based on a JPEG 2000 coding framework with newly introduced
coding technologies.
Applications
- A minimal delay HDTV transmission via normal transmission
line by DVB-ASI interface
- Sports live HDTV transmission via FPU (Field Pick-up
Unit)
Characteristics
- Introduces newly developed advanced technologies
into JPEG2000 standard coding
- Achieves HDTV program contribution via normal TV
links even at the bit rate of 45Mbps
- A minimal delay coding mechanism is introduced‚and
the total coding delay(ENC−DEC)can be reduced to less
than 50msec
- Every HDTV format is supported as an input video
signal
- Easy to operate GUI or monitor display
- Typical Digital Cinema format is also supported
by applying the 1080/23.97p input mode. Transport
protocol is based on MPEG-(Transport Stream)‚ and
DVB−ASI is adopted as a popular transmission interface
