In 2013 I was part of a team who migrated York Student Television (YSTV) away from its old composite-video-based vision path and onto a new one with HD-SDI video links, based around a Blackmagic Design ATEM mixer.

YSTV have a fairly small studio; running 3-4 HD cameras (Sony HD1000Es at the time), a VT input, and a graphics system, all streamed out onto their website. At the time they also had a playout server used to run a continuous live channel, but that's now become defunct.

I did some of the design work to figure out which components would be needed and how they would fit together, along with installing the new hardware and fixing various bugs that came up along the way. As a result, the technical quality of YSTV's live output improved significantly!

Somehow we also managed to squeeze HD-SDI down the station's ageing coax cable, and convince the super-cheap HDMI converters we got off eBay to de-embed audio onto the even-cheaper TVs!
