  1. [i-Definition TV transmission over VHTL6 system Authors: Date: 2009-01-19 Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  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. Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  3. Background Hi-Definition TV Transmission System Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  4. Proposed system • Specification • Hi-Definition TV • Compression： • JPEG 2000 • Error correction: • LDPC, Viterbi • Carrier Frequency： • 5GHz Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  5. Why we chose JPEG2000 Block noise MPEG-2 JPEG2000 Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  6. Proposed wireless system • (1) Pre / Post-Processor • Decode the video data • (2) JPEG 2000 Encoder / Decoder • Encode the video data by JPEG 2000 + ERT • (3) Wireless Transmitter / Receiver • Transmit the video data Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  7. Specification of the proposed VHT system • Throughput is 1.5 Gbps • Operating Clock • Single Clock of 80 MHz • Based on IEEE802.11 TGac (even though it is not decided yet) • Main Components • FFT/IFFT Processor • Viterbi or LDPC • 4x4 MIMO Detector • MMSE Detector  MLD • MIMO Channel Estimation • SINR Computation for Soft-Decision Demapper Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  8. The developed VHT system • Transmitter • Receiver Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  9. LSI Design Results • 512-pt. FFT • Fixed -wordlength • 16 bits (TX) • 20 bits (RX) S.Yoshizawa, Y. Miyanaga, "VLSI Architecture of a 4x4 MIMO-OFDM Transceiver for over 1-Gbps Data Transmission," IEEE ISCIT, pp.422-425, Oct. 2008. Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  10. Error Resilience Tools (ERT) Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  11. Simulation Parameters Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  12. Simulation results (2K:2048x856) • Evaluated using PSNR PSNR=Peak Signal to Noise Ratio original PSNR[dB] Frame • The PSNR of all frames are below 30dB regardless of ERT • Unintelligible for a movie content Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  13. Simulation results (2K:2048x856) w/o ERT PSNR[dB] w/ ERT Frame • w/o ERT: 5% of the frames has PSNR < 30dB  movie is not clear • w/ ERT : All frames has PSNR > 30dB  movie is clear Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  14. Simulation results (2K:2048x856) original PSNR[dB] Frame • All frames has PSNR > 30dB  movie is clear Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  15. Compare w/ ERT and w/o ERT 2048 x 856, BER=10-6 Without ERT With ERT Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  16. Link Budget Analysis 40 17 Nishijo, Ochi, Miyanaga, Sai, KIT & HU

  17. 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 Nishijo, Ochi, Miyanaga, Sai, KIT & HU
