Getting it Right
It's time to go back to the drawing board and design a collaboration hub product that employs various protocols in creative ways, instead of being limited by them. There's nothing wrong with using Wi-Fi to connect users, but it doesn't make sense to rely on TCP/IP to handle every type of media we want to use in a presentation.
The appeal of BYODs lies in their being true plug-and-play devices. Just power them up and launch an app - that's all there is to it. There's no reason why our "ideal" collaboration hub product can't be just as easy to use, and it certainly shouldn't require any special add-on dongles that are incompatible with tablets and smartphones.
Instead, let's take the lead from BYODs and switch to a downloadable app to log into and operate our collaboration hub. Thinking further about the design, our hub should be expandable to a large number of users - equal to the largest block of IP addresses it can assign, which would be 255 simultaneous logins. And for end-users that require secure connections, strong encryption (1024-bit) should be a standard feature, along with dynamic room codes.
How about image tiling? Any one user can command the display screen. How about two? Three? Four or more users? Given the low cost and size of LCD displays today (and their full HD resolution), there's no reason why we can't easily show four, five, and even six simultaneous images on the screen, re-sized and tiled automatically by our collaboration hub. By adding support for a second screen, we can expand that to 12 simultaneous images.
The next step is to tackle the trickiest problem of all - streaming video. As we learned earlier, TCP/IP isn't a good choice for real-time video playback; not unless we add some sort of real-time transport protocol with adaptive bitrate streaming to support the higher frame rates (30Hz and 60Hz) that tablets and phones are capable of when operating in playback mode.
Surprisingly, none of the current collaboration hub products can do this. Yet, video streaming problems through collaboration hubs are still the #1 complaint of end users, particularly in the higher education market.
But our ideal collaboration hub will support full-motion 1080p/60 video streaming from multiple platforms - Windows, Mac OS, and even Android. Not 15-frame video, not 30-frame video - full 60-frame video, free of dropped frames and frozen images. And it will do this over conventional TCP/IP wired and wireless networks with no special protocols required.
While we're at it, why not include the ability to show the main display screen on our tablet or smartphone? (And all simultaneous images, too.) That function is easy enough to implement, as is an electronic whiteboard overlay for annotation and picture-in-picture (PiP). If our primary display is a touchscreen monitor, then its functions should also be supported by our hub.
Let's finish off the package with native app hosting, multi-user file editing and manipulation in real time, and quick file sharing capabilities. If one user wants to send another a file, they simply send it while a session is in progress. If several members want to mark up or edit a document, they simply edit it. And we can also support remote users who log in via Skype, Lync, WebEx, GoToMeeting, and other conferencing programs.
