Abstract
Method, system and computer program product are provided for adaptively encoding in hardware, software or a combination thereof a sequence of video frames in real-time. A first encoding subsystem analyzes the sequence of video frames to derive information on at least one characteristic thereof, such as motion statistics, non-motion statistics, scene change statistics, or scene fade statistics. The gathered information may be either an intraframe characteristic or an interframe characteristic. A control processor is coupled to the first encoding subsystem to automatically analyze the gathered information in real time and dynamically produce a set of control parameters. A second encoding subsystem, coupled to the control processor, then encodes each frame of the sequence of video frames employing the corresponding set of control parameters.
