As stated above, the electric cord 3 may be replaced by a wireless link.
Internal circuitry is contained within the unit 12 to enable it to effect its various functions to be described.
It should be pointed out that the electric circuitry employed within the unit may be of any well-known commercially available type, and, for that reason, will not be described in detail herein.
Also, the provision of a wireless link between the remote unit and the television receiver is also well known, and need not be described in detail.
The control panel of the remote unit is shown in FIG.
