Remote controller for a multi-device television receiving system providing channel number auto-completion, presettable audio hush level and base channel auto-reaffirm

摘要

A handheld remote controller for a televisor that automatically prefixes a single-digit program channel selection, typically between 2 and 9, with a leading zero in response to a prolonged single digit keybutton actuation exceeding about 3 seconds or by an intended ersatz key entry, such as a star * key, either preceding or following the channel digit key entry. A HUSH control provides audio volume reduction intermediate between mute and normal volume levels, obtainable by pressing a HUSH keybutton, or automatically hushed concurrent with a program channel change. Maintaining a televisor's necessitous channel 3 or 4 selection when used in conjunction with a cable box, VCR or other intermediate device is assured by concurrently sending a reiterative channel 3 (or channel 4) tuning command to the televisor whenever a program channel change command or other function signal is dispatched to the cable box, VCR or other television signal tuning apparatus.
