No. It's not a codec problem. They can leave it on the last decoded frame and fade it nicely to, say, the average color for the 1 second without going to black, and you don't have to be a super decoder genius to implement something that's a little less aesthetically jarring.

joncrane was complaining about the time to change channels. This approach does nothing to decrease this time.

Exactly. It does placate users with some indication of activity.

This can impact how someone feels about the change, but does nothing to solve the time to change problem.

One thing it does do is confirm the change is in progress. That is a subset of the time to change problem.

Many current UX on this do not give a very good, or any indicator of successful input.

Quite a few people may see their feelings about the time to change improve because they can diver their attention away from the change knowing it will eventually happen.

A black screen is also a sign that a change is in progress. But this is exactly what my parent fortran77 complained about (https://news.ycombinator.com/item?id=21835676).

There is no making all the people happy without just changing quick, eh?

You can show the program name and what's on on that black screen, this info is already available from EPG.

That's actually a nice spiff. Doesn't entirely fix the problem, but could help with surfers looking for something interesting.
