Sync-on-green
Component video requires an extra synchronization signal to be sent along with the video. Component video sync signals can be sent in several different ways: ;Separate sync: Uses separate wires for horizontal and vertical synchronization. When used in RGB (i.e. VGA) connections, five separate signals are sent (Red, Green, Blue, Horz. Sync, Vert. Sync). ;Composite sync: Combines horizontal and vertical synchronization onto one pair of wires. When used in RGB connections, four separate signals are sent (Red, Green, Blue, Sync). ;Sync-on-green (SOG): Combines composite sync with the green signal in RGB. Only three signals are sent (Red, Green with Sync, Blue). This synchronization system is used in - among other applications - many systems by Silicon Graphics and Sun Microsystems through a DB13W3 connector. ;Sync-on-luminance: Similar to sync-on-green, but combines sync with the luminance signal (Y) of a color system such as YPbPr and S-Video. This is the synchronization system no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DB13W3
DB13W3 (13W3) is a style of D-subminiature connector commonly used for analog video interfaces. The 13 refers to the total number of pins, the W refers to workstation and the 3 refers to the number of high-frequency pins. Usage It was used primarily on Sun Microsystems, Silicon Graphics (SGI) and IBM RISC workstations, as well as some displays from Apple Computer, NeXT Computer and Intergraph Corporation. The 13W3 connector is no longer used with modern displays; it was superseded for use with analog displays by the VGA connector, and as the display market has moved to digital flat panel displays that has in turn been replaced almost entirely by digital connections (DVI, HDMI, or DisplayPort). Non-video use A variant of the DB13W3 connector, with high-current pins instead of the high-frequency pins used for video applications, is also used by some 3Com SuperStack Ethernet switches to carry DC power. It has also been used in various industrial appliances. Specification ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
