VESA Releases Revised Video Signal Standard.Business Editors/High-Tech Writers MILPITAS, Calif.--(BUSINESS WIRE)--Jan. 22, 2003 The Video Electronics Standards Association See VESA. (body, standard) Video Electronics Standards Association - (VESA) An industry standards organisation created in 1989 or 1990 mostly(?) concerned with IBM compatible personal computers. (VESA (Video Electronics Standards Association, Milpitas, CA, www.vesa.org) A membership organization founded in 1989 that sets interface standards for the PC, workstation and computing environments. Note the following VESA standards following this entry. ), the worldwide leader in video display standards display standards - display standard development, today announced the release of the Video Signal Standard, Version 1, Revision 2. The Video Signal Standard (VSIS VSIS Vault Safety and Inventory System VSIS Victualling Stores Issuing Ship ) establishes standard analog video The original video recording method that stores continuous waves of red, green and blue intensities. In analog video, the number of rows is fixed. There are no real columns, and the maximum detail is determined by the frequency response of the analog system. signal characteristics for today's graphics cards and display monitors. To date, the graphics controller output signals that drive the display monitor have not been well defined. H and V sync signals are defined only as being TTL (1) (Time To Live) A parameter in a network packet that sets a time limit to its validity. In order to prevent an IP packet from propagating endlessly through the network, the value in the TTL field is reduced by each router. levels. The display side has the same problem, as each design may have been optimized to correct for certain signal deficiencies from particular graphics controllers. This document will lay the groundwork that both graphics controller and monitor designers can use to achieve compatible designs. According to Joe Goodart, VSIS Workgroup Leader and Displays Engineer at Dell Computer Corp., "This new revision of VSIS addresses the Hsync drive impedance problem. By defining a Hsync drive impedance we are able to source terminate the Hsync impedance to the monitor, enabling better overall system performance." Availability VSIS is available now and can be ordered from the VESA web site at www.vesa.org. About VESA Based in Milpitas, California, VESA is an international trade association serving more than 100 companies participating in the video display market. VESA maintains offices in Milpitas and Tokyo. Visit VESA on the worldwide web at www.vesa.org. |
