Abstract
Systems and methods in accordance with embodiments of this invention provide for encoding and playing back video at different frame rates using enhancement layers. In a number of embodiments, video is encoded using temporal scalability involving the creation of a base layer at a first frame rate and an enhancement layer including additional frames enabling playback at a second higher frame rate. The second higher frame rate can also be referred to as an enhanced frame rate. In a number of embodiments, the base and enhancement layers are stored in one or more container files that contain metadata describing the enhancement layer. Based on the capabilities of a playback device, it can select the particular frame rate at which to playback encoded video.
