  1. Web-Enabled Entertainment System By: Ajay Kosaraju Andrew Bianchi Panos Tzanos

  2. Presentation Goals • Motivation for our work • Objectives • Technology • Implementation • Problems • The Future • Conclusions

  3. Motivation • An end product that a consumer can use • Desire to web-enable an appliance • Wish to learn JAVA • Integration of hardware and software • Cutting-edge technology • Professional engineering experience

  4. And of Course… …to get an A!

  5. Why Web-Enable? • Make life easier • Allow people constant and instant access to their home appliances (e.g. coffee pot, oven, heating/cooling, home entertainment) • Security • Education • Communications

  6. Design Options • Hardware: • Low Cost • Easy to Use • Dependable • Software • Established High-Level Language-JAVA • Servlets

  7. Objectives • Allow a user to control his home entertainment system from the web • Do it in a way that does not take a lot of bandwidth (servlets) • Have an interface that is simple to use • Make it accessible to anyone on the world wide web

  8. Set-up: Computer Remote Control (SP4001) TINI Serial Ethernet Cable Infrared Entertainment System

  9. The Tiny InterNet Interface (TINI) Board • The TINI board is a JAVA web server that uses a TINI chip set plus commodity SRAM and interface circuitry in a 68 pin SIMM stick. • ~60 MHz clock rate • 4 MB NV SRAM • Real-Time Clock • Ethernet 10Base-T interface • RS-232 serial port interface

  10. Software: What You Need to Operate TINI • To operate the TINI board, download the tinibeta2.2 file. This can be obtained at www.ibutton.com/TINI/software/index.html • Download JAVA development software (JDK 1.1-1.3) from the Sun Microsystems web-site • Download a TINI web server from www.smartsc.com/tini/index.html • Develop your own servlet software!

  11. Servlets • What are they? • Server-side version of applets • Low bandwidth • Processing done on server • Use server for data storage and processing • Why did we use them? • The server software is optimized for servlets • Leading-edge technology • Thin clients – wave of the future

  12. Our TINI Servlet Software • Allows us to interface with the TINI through the world wide web • The user can select the different devices of his/her entertainment system (e.g. TV, VCR, Cable Box, DVD) • Enables a person to program different name-brand devices (SONY, RCA, Toshiba, etc.)

  13. Innotech SP4001 Universal Remote Control Chip • Convenient means of controlling TVs, VCRs, satellite dishes, cable boxes, and DVD players. • Innotech’s proprietary code library • Converts asynchronous serial data words into control signals for driving infrared diodes • Very robust

  14. Remote Control Circuit • Infrared LED has range of about three feet • Amplifies signal from SP4001 chip • Choppy crystal oscillator • Status LED for testing purposes • Don’t forget RS-232 to TTL converter!

  15. Serial Port • RS-232 DB-9 connection • Standard PC cable • DB-9: 8-pin hardware handshaking • TINI provides Rx, Tx, and ground: no flow control (unnecessary for SP4001) • DTR – normally Data Transmit Ready, used as manual reset on TINI

  16. Problems Encountered • Shipping delays • Integration of various software packages • Working with incomplete documentation • Beta version of TINI had incorrect resistors, DTR reset • IR LED very sensitive to ambient light • Weird flurries of crashes

  17. End Results • Ability to control basic functions of TV, VCR, and DVD player • Slow server response • Functional web page • No implementation for setting VCR to record future programs • Tested outside of ece.uiuc.edu domain

  18. Future • Install a graphics-intensive option • Create secure site with multi-user password protection • Implement VCR programmability • Develop support for other devices • Make TINI Slush OS more reliable • Web-enable the world!

  19. Conclusions • Web-enabled entertainment system is a step into the future – The Jetsons • TINI empowers integration of the web with everyday life • JAVA allowed us to abstract ourselves from low-level interfacing issues with TINI • Thin clients and the web are revolutionizing access: to the world, to people, to ideas • The internet is a tool to implement everything from national defense to turning on your TV
