A lot of the manufacturers are hanging their hats on their up conversion technology because there is no 4k content available.
I’m a software engineer and what they are trying to do is fill in data that doesn’t exist. In the case of 4k, they trying to go from your cable company’s 720p signal to a 2160p picture. So in essence they are trying to color in two thirds of the pixels with colors.
So how do you determine what pixels get what colors? Remember a TV is in continuously processing a huge amount of frames per second. As you can imagine the software to do this would have to be extremely complex and would have to run at tremendous speeds to process each frame. The hardware on your TV would also have to be extremely fast to run just this program for every frame, let alone all the other processing it needs to do with today’s TV’s.
So somehow up converting is “accurately” calculating or guessing what colors go into each of these vacant pixels. Sorry, but I think this would be technological wonder because if it doesn't work properly it would make the picture worse. I have a feeling these up conversion systems don’t really do anything , or if they do it is extremely marginal.
I think this is just another sales gimmick because there is no 4k content so they are selling up conversion. Before you buy a 4K tv, ask the sales person to put in a standard cable feed into the set and look at the picture. You will be disappointed. I have yet to see a TV up convert anything worth a crap.
