Will a TV always deinterlace video?
 
Ive been wondering - in which situations will a TV pick up and deinterlace material? If I save my videos and play them over an HDMI cable to my TV as a monitor, won't they still be interlaced as its a screen copy? If so, when will it actually properly render interlaced material?

When you send the signal to the TV as 480i or 576i (for SD material).

Right, but does it depend on the medium of delivery (dvd vs. pc hdmi hookup vs dvi htpc etc...)?

Not from the TV side of things. Are you able to set your PC to 720x480i? You would also have to ensure that each field of the video being played is being rendered at exactly the right time, 100% of the time. I've done it with a 1080i Blu-ray playing out from my computer to my TV at 1080i, and there were timing issues.

Interesting, so you actually set your PC to output interlaced videos?

So far, I've played
- 352x480 4x3 interlaced
- 352x480 4x3 progressive
- 352x480 16x9 interlaced (non-standard, but usually works)
- 704x480 4x3 interlaced
- 720x480 4x3 interlaced
- 720x480 4x3 progressive
- 720x480 16x9 interlaced videos

from my computer using Serviio (a DNLA)
to my 1080s 55" TV
using the WDTV Live (rev3) box

I watched a movie just last night.

... and those are just DVD ISO sources. It doesn't include all the AVI DivX/XviD, MKV and H.264 MP4 sources that play fine.

The TV itself does the deinteracing.

Interesting. I only ask because I figured if being sent over a digital signal like HDMI it wouldn't pick it up. Technology is pretty cool
