Outlines for Today

Introduction: Multimedia & End systems in the future

Things Other than Computers Telesurgery Network based robot Entertainment

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

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

TV2Me (Continued)

MPEG-4

An open international standard for multimedia

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

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

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

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

Remote Surgery

What is it? When telerobotic systems meets telecommunication

system• Physical Interaction

Motivation Inconsistent Quality of Surgical Proficiency Convenience CHEAP !!!???

Remote Surgery

The Robot – ZEUS Two Components

• Surgeon-side

• Patient-side

Telesurgical System Set Up

Network Communication

100 base-T ethernet UDP/IP A dedicated 10 Mb/s CBR ATM circuit with OC-3

fiber (155.52 Mbps)

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

Communication Anomalies

Single- or multiple-bit errors in a packet or Fragment

Dropped packets Delayed packets Out of order packets Their Solutions
