Broadcast engineering and IT related links and stuff. Maybe some music, films and other things. Friday, February 06, 2015. Using a monitor LUT to try and tame domestic TVs for grading rooms. The venerable old Rec.709. Colour space was first proposed in 1990 for HD Television and we still work to it today and the assumption is that pro/broadcast monitors will faithfully translate the Y, Cr, Cb data that comes down a video cable to the R, G, B pixels on the display surface. LG 55EC930V-ZA OLED TV. I used t...

Broadcast engineering and IT related links and stuff. Maybe some music, films and other things. Wednesday, July 22, 2015. Typical edit suite monitor calibration; some traps for young players. I spent the morning in a very typical Soho edit room with a JVC DT-V24-series. LED-backlit LCD as the "front of house" monitor and an LG LED-backlit LCD as the client display. The software I use with the Klein K10A probe). Just because you can read down at sub 1Cd/m2 doesn't mean you should! With LCDs when you get t...

Broadcast engineering and IT related links and stuff. Maybe some music, films and other things. Monday, March 23, 2015. Poor RGB separation in Plasma TVs and poor Barco broadcast monitors! The first observation is how bad Barco broadcast displays have become! I was very used to them in the eighties at the BBC but the RHDM-2301. Is a sorry excuse for a TV monitor. The marketing material say;. It's also kinda pointless for them to tell you the values of the primaries as well! They can't be adjusted. Using ...

Broadcast engineering and IT related links and stuff. Maybe some music, films and other things. Friday, March 20, 2015. Reliable Avid ethernet traffic over old fibres. And given a cautious thumbs-up. BUT, they are very expensive (a few hundred quid per workstation, so back to running new cable), but I had a quick chat with the guys at Comtec about the house-brand they supply. Which uses the same chipset. Kindly ran Avid's PathDiag. Not too shabby as they say in Boston! Note that the graph pattern drawn b...
