Video Disk Control Protocol
（重定向自VDCP）
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 Protocol. At the time it was developed when Hewlett Packard (eventually sold to Pinnacle Systems) and Tektronix were both bringing to market the first of the VideoFile Servers to be used in the broadcast industry. They contacted Louth Automation who then designed the communications protocol basing it on Sony protocols of both the Sony LMS Storage Device and the Sony VTR. The principal work was carried out by Ken Louth at Louth Automation.
