Abstract
A source image is encoded into a base layer and an enhancement layer. The base layer represents a standard definition portion of the source image and the enhancement layer represents a high-resolution portion of the source image. The base layer is stored on a first data storage track of a storage medium, such as a DVD, and the enhancement layer is stored on a second data storage track of the storage medium. The first data storage track may be a default camera angle track and then second data storage track may be a second camera angle track. The data is formatted such that a standard definition device will not read the enhancement layer data. A high-resolution decoding system decodes the base layer and the enhancement layer simultaneously to generate a high-resolution image.
