Stadium Project Design History

1. KMi 'Maven of the Month' Internet Talk Radio Interviews
Talk-radio style interviews with noted personalities ('maven' = expert or connoisseur), using RealAudio. Questioners filled in Web forms, and we then phoned them, using a telephone patch panel/balancing unit to handle the world-wide question queue.

2. Naive Auditorium presentations (slide shows, tutorials and panel discussions)
These were formal presentations or discussions, accompanied by high-quality graphics in a custom slide-show viewer which could be controlled indirectly by the presenter using synchronization cues signalled in a separate frame to the remote participants. Everyone managed their own slides and controls!

3. Java Podium 100% Java-based presentations
Similar to (2) above, but streaming audio and remote control of graphics are all done entirely in Java, enabling precise fine-grained synchronization controls.

4. Basic Web-Browser Frame-Based Webcasts
Events based primarily on the audio content delivered via RealAudio, and occasionally accompanied by static graphics or a simple HTML slide show. A hidden web frame held the slide number which was pulled from the server by regular client-javascript calls, which then kept the client slide in synch.

5. Advanced Web-Browser Frame-Based Webcasts
As with 4. above these events used a simple HTML slide show set into frames in a web-browser, but in the more advanced version we used server side controls (written with perl) to synchronise the clients. Slides were also all cached using javascript arrays to hold text and image information - this avoided any AV interruption during an intensive slide switch.

6. Java Arena Prototype
This is the original KMi Stadium Java implementation widely known for the world map, 'choose-your-own-face entrance', 'cartoon presenter hands' and 'applause/laughter' buttons prototype features.

7. Java Lyceum Prototype
The Stadium Java implementation moved into a multi-party voice application prototype which has now moved out of the Stadium 'stable' and has been delivered as a robust product by the Open University Learning and Teaching Solutions as Lyceum.

8. Basic Shockwave Applet Prototype
This incarnation of KMi Stadium technolgies has been used in a variety of clients, such as a business application within BP Amoco. This is the software which was initially licenced by our spin off company WebSymposia to help corporate clients to explore their webcast requirements. This work was showcased on the Macromedia Website.

9. Advanced Shockwave Applet Prototype
This development was used for events such as the OU virtual degree ceremonies and for NHS Webcasting Events - using back-end solutions, written in php and coldfusion to handle timing and slide-pack processing; and with a range of vital administrative features in the shockwave applets, such as state-information, eg. "live", "rehearsal", "intermission", and so on.
