Hi,

I think most people are annoyed because of this delay and witch it off. I did it a few years ago. It is funny some boxes can switch channels in 0.1 seconds but TV needs 2-3 seconds to switch resolution:-)

Hi,

why not? At least films have a certain limited number of aspect/ratios which are standard. You cannot take all the garbage of the internet into account but for films you can.

 

I know that E2 is for STBs and of course we are only using E2 to watch sat and cable TV and the recordings:-)

Hi,

I think Ben Hur is pretty unique. Most current films use 21:9 but this also causes problem in HD because it would result in 1280x536. In the 50th and 60th also aspect ratio up to 24:9 were used.

 

@nautilus7,

this is the reason I changed it a few years ago that broadcast formats were send to TV in their native resolution. Because E2 is used for sat/cable STBs does not mean that you do not have to care about the rest of the world. In my example 21/9 you see that the problem is with current films and a HD resolution!

Hi,

the highest "normal" aspect/ration I know is 25/9 (Ben Hur) which means for 4K a height of 1386, for FHD 693 and for HD 462. In this case FHD and Hd were wrong classified when using height.

 

When I changed something in AR of OpenViX I only allowed the official width of broadcast standards (704, 720, 1280, 1920, 3840) to be send to the TV without scaling in the box in their native resolution. In case of 704/720 the frequency 24/30/25 must also be taken into account.

 

Otherwise senseless double scaling takes place like 480 -> 576 ->4K which is worse than 480->4K. Here in Germany we also have these funny resolutions like 1440x1080, which is also used on some b-channels, Should not be scaled by box to 1920x1080 and then by the TV to 3840x2160.
