Television has bad UX. To fix it, I can suggest: Don't use the cursor movement function. Allow the numbers to be used to specify channels, input selection, timer for sleep timer and recording duration and others, and whatever else you might use it for. Allow commands to have optional numeric prefixes (like vi does). Don't add functions that will delay after the command is entered and then execute it; if the user has not finished entering it, then the user has not finished entering it. Allow OSD to be disabled. Don't use so much fancy UI animations and that stuff. Don't use virtual channel numbers.
