Abstract:
A remote control method for allowing a plurality of related entertainment appliances to operate in the same environment, comprising the steps of:immutably storing in a remote controller a first alpha encoding data set, a second alpha encoding data set, and a first beta encoding data set, wherein the signals corresponding to the first alpha encoding data set are different from the signals corresponding to the second alpha encoding data set, and wherein the remote controller is selected to send only the signals from one of the encoding data sets; immutably storing in a first remotely controlled apparatus a first alpha decoding data set; immutably storing in a second remotely controlled apparatus a second alpha decoding data set and a first beta decoding data set, wherein the second remotely controlled apparatus is selected to use one of the decoding data sets; wherein the decoding data sets are used to decode the signals from their respective encoding data sets; utilizing a keypad to enter a command to cause the remote controller to send a first alpha encoded data signal to the first and the second remotely controlled apparatus; using the first and the second remotely controlled apparatus to receive the encoded data signal; using the first and the second remotely controlled apparatus to decode and to execute the command corresponding with the signal if the decoding data set is compatible with the first encoding data set; observing that the second remotely controlled apparatus improperly decodes and executes the first alpha encoded data signal; and switching the second remotely controlled apparatus to an alternative decoding data set.
