HDTV JPEG2000 Codec - JH2000

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
