VDCP uses a tightly coupled master-slave methodology. The controlling device takes the initiative in communications between the controlling device (automation) and the controlled device (video disk). VDCP conforms to the Open Systems Interconnection (OSI) reference model. VDCP is a Serial Communications protocol based on RS-422 . It is derived from the Sony 9-Pin Protocol , an industry-standard protocol for control of professional broadcast VTR s. Full details of the protocol are available from Harris Broadcast , a division of Harris Corporation who acquired Louth in 2000 . In 2001 Harris announced the introduction of NDCP , a TCP/IP-based successor for VDCP. Little information on NDCP is readily available, and thus VDCP has remained the de-facto standard.
