Abstract
An encoder of a multimedia system encodes data representative of each image in a video stream to form a bitstream that is transmitted over a network to a decoder that decodes the bitstream and provides the decoded information to a multimedia application for display to the user. As consecutive images may have nearly identical pixel values, the multimedia system detects pixel value variations between consecutive images that are below a specified threshold to reduce active processing on such pictures, which includes, for example, encoding, decoding, and post-processing. The multimedia system either selectively encodes or selectively processes the current image that has pixel values that vary from an immediately preceding image within the specified threshold.
