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.

Conclusion

• VHTL6 System already developed

• Can be used to transmit Hi-Definition TV using JPEG2000 codec– Without ERT case, BER should achieve 10-8

– With ERT case, we only have to attain 10-6

Future work• Hard Ware implementation and its verification• 4K Digital cinema
