ABSTRACT:
A transponder for use with a pair of dual-controllable systems remote from each other, such as a two-player computer operated game, allows the players and their associate game units to interactively play against each other from remote locations.
The transponder receives status words from an associated controller, retains a copy in temporary storage, and formulates command words for a similarly configured transponder associated with the remote unit. The command word includes a status portion comprising a replica of the stored word, an error detection code, and a confirmation code. The error detection code is used to detect transmission errors in received words, and the confirmation code is used to indicate error-free reception of words from the remote unit. A command word is sent responsively to receipt of each received command word. If the error code of the received word indicates error-free reception of the received word and a confirmation is also received, the status portion of the received word and the stored word ar presented to a pair of output ports for transfer to the associated game console. The baud rate of the communication system linking the two transponders allows a word-pair to be generated in less that one-thirtieth of a second, allowing asynchronous operation.
