OpenOB‘s been ticking along nicely but it’s historically needed a bit of oomph and capital in the form of two computers running Linux. This isn’t often what you’ve got on your PC and it’s not something you can easily chuck in your reporter’s rucksack to take along to an event.
This limits its usefulness somewhat. So what you need instead is something cheap, small, and lightweight, that can run Linux and do everything you need it to with regards to OpenOB and network management.
Enter the Raspberry Pi, the £25 wonder-SBC. It’s got audio out (not in), runs Linux off an SD card, is small, runs off 5V power supplied via USB, and did I mention it’s £25? Okay, £30 if you buy from Farnell with shipping thrown in, and probably more like £60 when you’ve bought a power supply, sound card, SD card, etc. But we’re still talking an outside broadcast remote and receiver for a grand total of around £200. Compare that with the £1,500 per end of the current cheapest commercial solution, or the £5,000+ an end and up boxes found in most professional OB trucks. Sure, you don’t get their slickness or polish or even all their features, but you can move audio and you can do it well with OpenOB. With Opus, now from 16kbps all the way to 384kbps or linear PCM.
The primary OS supported for the Pi is Raspbian, a Debian derivative, which is awesome – because Debian/Ubuntu is the standard platform on which I develop OpenOB.
So can we actually make this perfect storm come to pass?
