These labels are used to describe image size, which is related to resolution. In an NTSC video, standard full-screen resolution is 704x480 pixels. The Standard Image Format (SIF) is 352x240 and the QuarterSize Image Format (QSIF) is 276x120 pixels. The picture in an SIF file is bigger, but so is the data file! If you need to enlarge a QSIF to be full screen, the resolution (and picture detail) will be greatly decreased compared to an SIF of the same image.
hope this helps.
