576p is the shorthand name for a video display resolution. The p stands for progressive scan, i.e. non-interlaced, the 576 for a vertical resolution of 576 pixels, usually with a horizontal resolution of 768 or 1024, depending of the relationship aspect. The 576p quality was decided as the default quality when converting from VHS to digital. 576p is considered standard definition for PAL video. The frame rate can be given explicitly after the letter.
