Live TV Over the Internet

• Purpose
• To watch live TV anywhere there is a high speed
  internet connection
• To watch live TV from a far away location such as
  another country
• To watch local TV while away from home

Remote Surgery

• What is it?
• When telerobotic systems meets telecommunication
  system
• Physical Interaction
• Motivation
• Inconsistent Quality of Surgical Proficiency
• Convenience
• CHEAP !!!???

12
Remote Surgery

• The Robot ZEUS
• Two Components
• Surgeon-side
• Patient-side

13
Telesurgical System Set Up
14
Network Communication

• 100 base-T ethernet
• UDP/IP
• A dedicated 10 Mb/s CBR ATM circuit with OC-3
  fiber (155.52 Mbps)

15
Things to Transmit

• Video 70 of bandwidth
• Full-motion phase alternating line video
  displayed on a 21 high-resolution medical-grade
  monitor
• UDP packet
• From surgeon to patient
• 152 bytes in size with 128 packets per second
• From patient to surgeon
• 88 bytes in size with 128 packets per second

16
Communication Anomalies

• Single- or multiple-bit errors in a packet or
  Fragment
• Dropped packets
• Delayed packets
• Out of order packets
• Their Solutions
