This is an easy one. Probably the most trivial idea yet, but I believe it to be something that would have tremendous value to the millions of TV watchers. Let’s say you are browsing around the “dial” watching cable TV. You have at least a hundred channels with cable or satelite these days, and likely half of them are duplicates. They are duplicates because for nearly every channel these days, there is a high definition version of it. Most remotes have a “last” or “previous” button. They should add a HD button. You are browsing around and find a cool show to watch, but you would rather see the HD version of the program, and you don’t want to open up the guide, and then scroll up to the higher range of channels to find out if it’s even there. What a waste of time. Conversely, you are watching an HD sporting event and you frankly like the layout of the nonHD better. Very simply, the button would automatically switch to the HD version of the channel you are watching, or vice versa. If there was no HD or nonHD equivalent, it would simply put up a prompt, “channel not available.” That would be a cool feature.
