E to E Ltd in Leeds build OB trucks but I spent a week working with one of their engineers, Jonathon, commissioning JML's studio in Kentish Town, North London. Those guys really pushed the boat out with XDCam (see my mobile blog pictures) and an MXF workflow over gigabit. They also have a nice big 5 camera studio with play-in and transmission off Grass Valley M-Series servers (nice units - they support most protocols & compressions standards). I enjoyed a week of being a proper television engineer again!
