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

Live TV Over the Internet r Purpose m To watch live TV anywhere there is a high speed internet connection m To watch live TV from a far away location such as another country m To watch local TV while away from home r Hardware m TV 2 Me m Sling Box m Sony Location. Free r Software m Orb

TV 2 Me r Preprocesses and encodes the video through hardware on the sending side m MPEG-4 encoder r Receiver side is software r Full Screen TV Quality video at 384 kbps m Point-to-point r Dell PC with a custom video capture board r $4750

TV 2 Me (Continued) Source: www. tv 2 me. com

MPEG-4 r An open international standard for multimedia

Sling Box r Works like TV 2 Me r Encodes into Microsoft’s Media 9. 0 format r Video quality worse than TV 2 Me r Works with 802. 11 b and 802. 11 g networks r Uses a Digital Signal Processor (DSP) made by Texas Instruments r Uses a proprietary steam optimization code-named “Lebowski” r $249. 99

Sony Location. Free r Base station behaves like TV 2 Me and Sling Box r Encodes in MPEG-4 r Works with Location. Free TV, PC, or the Sony PSP r Better in-home quality than TV 2 Me but worse quality over the internet r $349. 99, $1499. 99 with 12. 1 inch Location. Free TV Source: www. sonystyle. com

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

Wireless TV Summary r Hardware or software compresses live TV video and sends it over the internet r TV 2 Me has best quality over the internet but costs the most r Sling box and Location. Free have lower quality video than TV 2 Me but are priced for the mainstream market r Orb is a free application and service that uses your home computer to send digital media

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

Remote Surgery r The Robot – ZEUS m Two Components • Surgeon-side • Patient-side

Telesurgical System Set Up

Network Communication r 100 base-T ethernet r UDP/IP r A dedicated 10 Mb/s CBR ATM circuit with OC-3 fiber (155. 52 Mbps)

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

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