Do we broadcast at 1080p?
1080P broadcasts started in 2011. https://www.theregister.com/2011/05/23/bbc_hd_1080p/
In recent weeks some programmes on ITV1 have been 1080p (e.g. Downton Abbey).
No - that's double the data rate and therefore double the bandwidth and double the transmission cost, and unnecessary.Is nothing broadcast as 1080p50?
Probably got US English selected(Why is FF putting a red underline thingy under 'programme'? Grrr...
Does that mean it can pass through untouched?It's a custom Dynamic Refresh setting.
So 50Hz is never needed for TV? Even setting it as your output on a box or your TV is unnecessary?No - that's double the data rate and therefore double the bandwidth and double the transmission cost, and unnecessary.
The human visual system (eye and brain combined) does not require refresh faster than 25 frames per second to perceive stop-motion as continuous movement. It's only gaming geeks who want the fastest possible response time for elite competitive gaming and claim to need 50Hz+ refresh rates (and are prepared to spend a fortune on 120Hz monitors plus the necessary hardware to drive them).
Well, for the vast majority: no. There might be just a few people who can perceive some jerkiness in fast action at p25, but that pretty much disappears by using interlacing - you get a low-res image every 1/50s, which integrates over two frames to produce a full-res image.So 50Hz is never needed for TV?
I have my PVR output set to 1080i, because there's no visible difference and it cuts HDMI radiation. The HDR-FOX output setting "1080i" means 1080i25, and the setting "1080p" means 1080p50 - twice the bandwidth, pushing the noise spectrum into the UHF band, and the extra information has to be invented (interpolated) anyway.Even setting it as your output on a box or your TV is unnecessary?
Is it really that simple? I thought it was simple but not that simple. For Firefox doesn't dictionary "British English Dictionary (Marco Pinto)" also need to be installed?
Right click? What about mobiles?
By convention it is TV programme and computer program.(Why is FF putting a red underline thingy under 'programme'? Grrr...)
Only in British English. Anything locked into American spelling will regard -mme as a mistake.By convention it is TV programme and computer program.
Well, after all these years I never knew that. Spot on!
Indeed. And I was talking about the former.By convention it is TV programme and computer program.
