capability. It also supports component output support for EDTV displays at
480i (interlaced scanning), 480p (progressive scanning), and for HDTV
displays at 720p, and 1080i.
VideoShader™ HD
A feature that integrates pixel-shading technology with video filtering and
processing functions. It accelerates noise removal, de-blocking, adaptive
de-interlacing, frame-rate conversion, color-space conversion, and more. It
also enables better MPEG-2 decoding with motion compensation.
VPU Recover
A feature designed to significantly reduce the number of system crashes
caused by problems occurring with the graphics hardware. If the display
driver detects that the graphics processor has hung, VPU Recover will
attempt to reset the graphics processor, eliminating the need for a system
reboot and allowing users to continue using the computer without
interrupting or losing their work.
YPbPr
A type of analog composite video signal that splits and compresses the
standard Red/Green/Blue (RGB) colors of a television signal into separate
luminance and color values. The "Y" stands for the luminance channel,
while "Pb" and "Pr" represent the blue and red channels respectively, both
of which have the luminance value subtracted from them. It is an equivalent
color space to the chrominance-based YCbCr, which is used for digital
video.
Z-buffer
The portion of video memory that keeps track of which onscreen elements
can be viewed and which are hidden behind other objects. In the case of a
3D image, it keeps track of which elements are occluded by the foreground
in relation to the user's perspective, or by another 3D object.
