Some Background Material
Quick introduction to the world of digital TV
What is a Set-Top-Box?
What is an EPG?
What in the world is Sky TV?
The experiences I'm writing about is about past projects that I personally worked on or touched in my time a Middleware Development Owner & Middleware Products Manager, that are very much in the public domain:
BSkyB replacing OpenTV HDPVR with NDS technology
Fusion is the new NDS Mediahighway to displace OpenTV
BSkyB Launches new HDPVR
Sky Italia replacing OpenTV HDPVR with NDS Mediahighway
Sky Deutchland delivers enhanced VOD powered by NDS Mediahighway
UPC being powered by NDS MediaHighway
Take a look at this video clip:
Yes, this is the background project I was fortunate to work on, which forms the basis for my writing on a large-scale software development project. We were responsible for delivering the core software component (Middleware / Operating System) that enabled the EPG (UI Application) to be developed to offer the Sky Anytime+ User Experience.
On the surface, when interacting with an EPG, the user experience might suggest this was a simple application, compared to powerful PC software products like Excel/Word or Adobe Photoshop; surely it can't be a complicated endeavour to create this system? That's not entirely true: Beneath the seemingly simple UI is a complicated piece of software and electronics, so much so, that typical projects such as this one takes at least three years to complete (if all goes well)...
The project was greenfields development on all fronts for the software vendors employed, especially on our side for the Middleware component. But for the broadcaster it was a massively complicated migration project, because essentially we were replacing the full software stack of a legacy deployed based of 4 million+ STBs, with the option for rollback!!
The project, though massive in size, relied on a core product & architecture team to manage the roadmap and project planning; supported by a very large technical team (software engineers, integrators & testers) that were geographically distributed throughout the world. Having joined the project a year-and-half into its development cycle, then spent the next two years executing and driving through the implementation and delivery to Launch Candidate builds, I played primarily the role as Middleware Development Owner. I inherited the Agile founding principles of the Programme, which after two full years of practical exposure, resulted in a deep appreciation for Agile, such that all my subsequent projects going forward re-used and evolved the model based on those principles. I later joined the Product Management team that championed the processes through roadshows, training and ramping up new project managers on the "Project Toolbox" required to deliver all future customer projects...
