SDI is the acronym for Serial Digital Interconnect.
HD-SDI is the High Definition version
Typically, HD-SDI is normally transmitted over digital video grade RG6-style low-loss coaxial cable up to a nominal maximum distance of about 100 meters.
Many variables will Change this nominal distance. The quality of the cable is extremely important. Another factor that affects the distance is dependent on the peripherals and the quality of the interface. More importantly the bitrate used of the HD-SDI and weather the signal is compressed or not compressed.

HDCP is the abbreviation for High-bandwidth Digital Content Protection. HDCP is a copy protection scheme to eliminate the possibility of intercepting digital data midstream between the source to the display. The system is meant to stop HDCP-encrypted content from being played on unauthorized devices or devices which have been modified to copy HDCP content. Before […]

Display Modes researched by: John Vellone The term display mode refers to the characteristics of a computer display, in particular the maximum number of colors and the maximum image resolution (in pixels horizontally by pixels vertically). There are several display modes that can be found in personal computer (PC) systems today. The earliest displays for […]
Defining Resolution By John Vellone In computers, resolution is the number of pixels (individual points of color) contained on a display monitor, expressed in terms of the number of pixels on the horizontal axis and the number on the vertical axis. The sharpness of the image on a display depends on the resolution and the […]
