Remote Surgery Solutions for Future Medical Advancements

This outline discusses the future of multimedia in remote surgeries, including telesurgery, network-based robots, and live TV over the internet. It explores hardware and software options like TV2Me, Sling Box, Sony LocationFree, and Orb as tools for accessing live TV remotely. The section on remote surgery details the technology behind telerobotic systems merging with telecommunication, focusing on the ZEUS robot for telesurgical procedures. The communication setup, bandwidth allocation, and potential anomalies are also examined.

Presentation Transcript

  1. Multimedia applications and end systems Chao-kai Ching, George Lin, Yevgeniy Razuvayev Dept. of CS&E The Ohio State University Columbus OH 43210 (ching.17, lin.539, razuvayev.1)@osu.edu

  2. Outlines for Today • Introduction: • Multimedia & End systems in the future • Things Other than Computers • Telesurgery • Network based robot • Entertainment

  3. 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 • Hardware • TV2Me • Sling Box • Sony LocationFree • Software • Orb

  4. TV2Me • Preprocesses and encodes the video through hardware on the sending side • MPEG-4 encoder • Receiver side is software • Full Screen TV Quality video at 384 kbps • Point-to-point • Dell PC with a custom video capture board • $4750

  5. TV2Me (Continued) Source: www.tv2me.com

  6. MPEG-4 • An open international standard for multimedia

  7. Sling Box • Works like TV2Me • Encodes into Microsoft’s Media 9.0 format • Video quality worse than TV2Me • Works with 802.11b and 802.11g networks • Uses a Digital Signal Processor (DSP) made by Texas Instruments • Uses a proprietary steam optimization code-named “Lebowski” • $249.99

  8. Sony LocationFree • Base station behaves like TV2Me and Sling Box • Encodes in MPEG-4 • Works with LocationFree TV, PC, or the Sony PSP • Better in-home quality than TV2Me but worse quality over the internet • $349.99, $1499.99 with 12.1 inch LocationFree TV Source:www.sonystyle.com

  9. Orb • Software so no need to buy any hardware • Streams digital media from your home PC • Can use TV Tuner on home PC to stream live TV • Requires Windows XP Media Center • A free service. Just need to download the software and register an Orb user name and password • Can work with mobile phones and PDAs as well as laptops

  10. Wireless TV Summary • Hardware or software compresses live TV video and sends it over the internet • TV2Me has best quality over the internet but costs the most • Sling box and LocationFree have lower quality video than TV2Me but are priced for the mainstream market • Orb is a free application and service that uses your home computer to send digital media

  11. 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
