JVS specifies the type of connectors to use for video (HD-15), audio (RCA) and power (JST VL), in addition to the communications protocol between the game board and the I/O board.  In contrast to (old) JAMMA, JVS concentrates I/O functions in a separate board.  The protocol is well documented, but only in Japanese (thank you google translate & altavista babelfish :) )
