A portable remote controller for use with several remotely controlled
entertainment devices which enables their concurrent usage in shared
proximity without random interference between remotely submitted and
individually directed encoded device commands. Discusses a provision for
user accessible preselection between more than one alternative encoding
and decoding data format when a command sent to one device appears to
cause undesirable random interference with another device's functions. A
user's preemptive selection of an alternate remote control encoding format
assures the proximal, concurrent use of two substantially identical
devices, such as two VCR-machines, without command interference. When a
user finds objectionable command interference caused by mutual remote
controller coupling, the user may select and preset a distinctly different
code format for at least one of the remotely controlled devices.
