Definitions

  • This invention is directed to home entertainment remote control devices and in particular, to a user interactive remote controller.
  • This unit was a learning remote which learned the various infrared patterns transmitted by the intrinsic remote controllers supplied by various equipment manufacturers with home entertainment equipment such as televisions, stereo receivers, pre-amplifiers, video cassette recorders and compact disc players.
  • the introduction of the learning remote controller was soon followed by other units that contained libraries of control codes in their internal memories, thereby eliminating the need for the user to teach infrared control codes to the universal remote controller.
  • Both learning and pre-programmed code universal remote controllers were available in versions that provided additional features including multiple key sequence capability and day-time timers that could be used to control the equipment in the absence of an operator. These became popular as a means of replacing the recording timer, which was normally a part of VCR's, and helped consolidate the various aspects of manipulating multiple program sources and the VCR for unattended program recording. However, all of these units either required teaching infrared codes or programming timers or schedulers for unattended VCR recording and thus suffered from the same difficulties of use as the original VCR timers. Users were still required to read an operations manual which detailed many complicated programming instructions and then had to follow those instructions in order to program and use their equipment. The problem of user instruction generally remained unsolved.
  • the present invention remedies the situation described above by using a voice synthesizer to provide interactive prompting of the user as he/she proceeds to program the timers and other recording facilities of his/her universal remote controller, VCR or even satellite receivers, televisions and cable tuners that may be equipped with timers and controlling devices.

  • the VCR voice program marked as "patent pending, " does not use a voice synthesizer, but instead recognizes a limited vocabulary spoken by the user and employs the user's voice commands to program the VCR. Utilizing the VCR Voice Programmer, programming instructions are still initiated by the user, rather than the unit instructing the user.
  • the objects of the present invention are: To provide a universal remote controller; to provide a universal remote controller that is interactive with the user; to provide a universal remote controller that includes a voice synthesizer to prompt the programming actions by the user; and to provide such a universal remote controller which is useful in controlling VCR's, satellite receivers, televisions, cable tuners and other devices which may be equipped with timers and controlling facilities.
