Abstract
A system for generating a video signal in a selected one of multiple aspect ratios from play of a disk on which is recorded a motion picture in only one aspect ratio. The disk includes a code indicative of the recorded aspect ratio, and the player has a default aspect ratio setting which can be changed by the user. Typically, the recorded aspect ratio is 16:9, and the player can generate a video signal having any of 16:9, center cut 4:3, pan scan 4:3, and letter box aspect ratios. The player automatically generates the appropriate video signal in accordance with both its default aspect ratio setting and the disk code.
