Video Disk Control Protocol (VDCP) is a proprietary communications protocol primarily used in broadcast automation to control hard disk video servers for broadcast television. VDCP was originally developed by Louth Automation and is commonly called the Louth Protocollled 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 VTRs that is used in online editing.

Full details of the protocol are available from Harris Broadcast, a division of Harris Corporation who acquired Louth in 2000.
