1.3 Using this Guide
1.3.1 Purpose
This guide is intended to help the user utilize the Elecard YUV Viewer. It describes the
YUV Viewer GUI, settings and functions and provides instructions for using the viewer.

The following section defines terms used throughout this document:
• PSNR - Peak Signal-to-Noise Ratio.
• NQI - New Quality Metrics.
• VQM - Video Quality Measurement Techniques.
• YV12- this is the format of choice for many software MPEG codecs. It comprises an
NxM Y plane followed by (N/2)x(M/2) V and U planes.
• IYUV (and I420)- these formats are identical to YV12 except that the U and V plane
order is reversed. They comprise an NxM Y plane followed by (N/2)x(M/2) U and V
planes.
• UYVY - YUV 4:2:2 (Y sample at every pixel, U and V sampled at every second pixel
horizontally on each line). A macropixel contains 2 pixels in 1 u_int32.
• YV16 - 8 bit Y plane followed by 8 bit 2x1 subsampled V and U planes.
Note: For detailed definition of video formats please read Microsoft® DirectX®
documentation or find the information at http://fourcc.org/yuv.php.
