Transition Minimized Differential Signaling (TMDS)
A technology designed to reduce electromagnetic interference (EMI) and improve the digital signal delivered to flat panel displays. Its encoding algorithm converts the original 8-bit graphic data into a more fault-tolerant 10-bit signal, which is then converted back to its original 8-bit form at the display device. The signal is also DC-balanced, allowing for the option of transmitting the signal over fiber-optic cable. DVI connectors can incorporate up to two TMDS links, with each “link” comprised of the number of signals required for standard RGB output. Higher resolutions and refresh rates than standard are possible if multiple TMDS links are available by using multiple DVI connectors.
Trilinear Filtering
A sampling method used to produce realistic-looking 3D objects. Trilinear filtering averages one of the bilinear filter mipmap levels along with the standard mipmap samples.
Vector Adaptive Deinterlacing
A technique that provides smoother, less jagged edges for interlaced video playback. Interlaced video consists of alternating odd and even numbered scan lines, which are then mapped to an equivalent pixel-by-pixel display on a CRT or Flat Panel Display. Without correction, jagged lines appear in a video image either as doubled scan lines or lines that are improperly interpolated. With vector adaptive deinterlacing, the difference in pixel values is considered across multiple lines and alternating frames (using Pulldown detection on the interlaced video source), and then intelligently re-interpreted to produce smoother edges in interlaced video images.
VersaVision™
An ATI technology enabling accelerated display rotation and scaling. Any desktop can now be rotated 90 degrees left or right, or even 180 degrees, while maintaining the full feature set of other ATI 2D and 3D technologies,
such as SmoothVision™. VersaVision™ works with single or multiple displays.
Vertex Shader
Three-dimensional objects displayed on a screen are rendered using polygons, each of which is made up of intersecting triangles. A vertex is a corner of a triangle where it connects to another triangle, and each vertex
