- Behind the scenes using Onboard Helmet cameras for the 2018 Winter Olympics in South Korea.
This is my vlog of the Journey and experience whilst I was there, the temperature was usually around minus 10 it was really cold.
I was in South Korea to look after the live tv - helmet cameras on the down hill skiing. I developed the system back in London and so then I operate them during the events.
I filmed this vlog with only a Samsung Galaxy S7.
For the middle 12 days I had the worst cold ever so I didn't film anything on those days but this is the best of what happened in a month.
On my return to the UK it has also started snowing at home.

한국사람입니다 유튜브 잘 보고 있습니다
감사합니다
my interest is in Audio visual integration
I appreciate all your effort Andrew,
Love from Mumbai, India
this is so amazing ...surely after watching i hav lots of questions to ask
Thanks for watching, no worries, ask away :)
-What is the RF distance range of the POV cams?
-what is Video output ..format/codecs of the POV cams?
-How do u integrate video feed from big cams with the POV cams?
-What is the delay time in the RF feed....how do u sync it with other feeds from broadcast cams ?
-When is fiber used? (is it from Rx antenna to converter ..or from converter to OB van)?
-How do u deal with the battery issues of the POV cams?
Hiya,
The POV cameras at Pyeongchang had a 100mw output COFDM so distance was within a few hundred metres, therefore 16 antennas using RF over fibre from downconverter back to control room. Distance was up to 3km per antenna. We were running 1080 59i on the cameras for Asian market. The cams were decoded, converted back to hdsdi and fed into the truck where they then appear on the stack for the director and on Evs.
16 rf inputs are fed to a RF router and then fed into cofdm receivers , each receiver has 8 way diversity inputs which then decides and outputs hdsdi.
Delay time was about 5 frames, so they could use it live without issues. Head mount POV has a remote control system which can be controlled from the control room, so we only turn on the cameras 30 seconds before the athlete goes down the hill. Saving on battery when it isn't needed.
All good fun. We had 5 cameras in this setup. Hope this is useful.
The stream is a standard dvbt cofdm stream, h264. Running ultra low delay. Data remote control communications is LORA with transmitter at the top and bottom of mountain. Range of data control is more that 1 km.
Wow..this so amazing..yes this info is priceless...Esp for an aspiring broadcast tech'n/Eng like me.
