  1. Wireless Video System Project # 36 Spring 2000

  2. Team Members • Omar Sherif M. Iqbal • Ryan Daulton • Deepesh Patel Designers : Teaching Assistant : • Amit Nainani

  3. Why Wireless Video? • Hassle-free setup • Extended range • Mobility Applications • Surveillance • Remote viewing • Portable systems

  4. Original Design USB Cable Hitachi's USB Camera Microprocessor Serial Data TX In EZ USB Serial Out Chip Cable Clock 12 MHz MAX232 RX Out PC Serial Port Connector • USB • Compression/Decompression • GUI interface

  5. New Design Ripple Counter Clock 2.45MHz 2.4 KHz 614.4KHz Serial Clk Parallel Clk TX In Serial Data UART Out 8-bits Parallel Parallel Port Camera RX MAX232 Out PC Serial Port Connector • Parallel port camera • UART

  6. Camera How Does It All Work? • B/W CIF format (352x288) • 15 fps • 5:1 compression ratio UART • Converts parallel data into serial data • Goal • Serial rate of 38.4 kbps • -Parallel rate = serial rate / 16 = 2.4 kBps

  7. LINX module • 800 meter range • Operates on 928 MHz carrier frequency • Maximum data rate of 50 kbps PC • Max232 • Visual C++ program • QuickTime

  8. Testing Procedures 1 2 LINX TX RX NULL MODEM 3 4 UART TX RX TX RX PARALLEL WITH CAMERA

  9. Challenges and Problems • USB • Reading in data from parallel port • HyperTerminal • Experimenting with new technology

  10. Ideas for Improvement • High data rate transceivers • Two way communication for controlling camera • Data compression/decompression • Heat and motion sensors

  11. Cost • Web camera $60 • HP transmitter $24 • HP receiver $35 • 2 antennas $10 • Other $4 Total $133

  12. Marketability • Replaceable parts • Small size • Low cost • Long range • Numerous applications

  13. Conclusion • USB is complicated • More research is needed for newer technologies • Interfacing different parts is time consuming • Real-time video requires high bandwidth
