media system design
DESCRIPTION
A presentation I did a while back at the LDI@ASU Projection Design & Content Creation workshop. This presentation focused primarily on overall system architecture for media system design and integration. Application Focus: - corporate events, press events, concerts, tours, etc. - trade shows, exhibits, pop-up experiences, etc. - theater, dance, opera - houses of worship - permanent installations, museums, retail, hospitality - architainment, theme parks, outdoor events, etc.TRANSCRIPT

traditional “one-offs”!! - corporate meetings - press events - televised events - concerts - tours
semi-permanent installations!
! - trade shows - exhibit booths - “pop-up” experiences - theatre, dance, opera - houses of worship
permanent !installations!
! - installed exhibits - museums - retail and hospitality - clubs and nightlife
architainment!! - theme parks - outdoor experiences
![Page 40: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/40.jpg)
40!
traditional “one-offs” - generally higher budgets - generally shorter design period and turn around - extreme reliability required: complete redundancy - require significant real-time previewing - require minimal show control
- corporate meetings - press events - televised events - concerts - tours
![Page 41: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/41.jpg)
41!
semi-permanent installations - generally medium to high budgets - generally high reliability and repeatability required - generally require real-time previewing - generally require some show control
- trade shows - exhibit booths - “pop-up” experiences
![Page 42: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/42.jpg)
42!
permanent installations - generally longer design and approval phases - sometimes require permits and facility support - sometimes require client-approved hardware - reliability and repeatability required - require complete system show control - must be designed with maintenance in mind
- installed exhibits - museums - retail and hospitality - clubs and nightlife
![Page 43: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/43.jpg)
43!

![Page 44: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/44.jpg)
PART FOUR designing the system
44!
![Page 45: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/45.jpg)
putting it all together - designing forwards (downstream) vs. backwards (upstream) - media system selection - redundancy and reliability - defining monitoring requirements - dealing with audio
45!
![Page 46: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/46.jpg)
designing forwards vs. backwards - what do you know?
- output displays? - content rasters? - interactive requirements?
- what kind of show is it? - does it need a presentation switcher? - how much redundancy is required?
46!
![Page 47: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/47.jpg)
media system selection - who’s your client? do they have an expectation? - what’s your budget? - what kind of “special” needs do you have?
- previsualization needed? - complex 3d mapping? - complex show control? - interactivity? automation? tracking?
47!
![Page 48: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/48.jpg)
redundancy and reliability - what kind of show? what are the redundancy requirements? - how many output channels? - does your router / switcher have the necessary capacity? - decide what kind of redundancy is necesary - create a “backup” plan
48!
![Page 49: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/49.jpg)
defining monitoring requirements - where is video village? - where is media system central? - do you need a foh location? - how many output channels? - what kind of redundancy?
49!
![Page 50: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/50.jpg)
dealing with audio - what media system are you using? - what kind of show? - how many channels of audio? - any infrastructure requirements?
- network based? - will be running near high interference?
50!
![Page 51: Media System Design](https://reader033.vdocument.in/reader033/viewer/2022052506/5562a324d8b42a7c4a8b4a0b/html5/thumbnails/51.jpg)
