Abstract
The invention comprises devices and methods for processing multimedia data. Such methods can include obtaining at least one metric indicative of a difference for a selected frame and adjacent frames in a plurality of video frames, the metric comprising bi-directional motion information and luminance difference information, determining a shot event in the selected frame based on the at least one metric, and adaptively encoding the selected frame based on the shot event. An apparatus for processing a multimedia data can include a motion compensator configured to obtain metrics indicative of a difference between adjacent frames of a plurality of video frames, said metrics comprising bi-directional motion information and luminance information, a shot classifier configured to determine a shot event in the plurality of video frames based on said metrics, and an encoder configured to adaptively encode the plurality of frames based on the shot event.
