REAL TIME ENCODING METHOD AND APPARATUS FOR VIDEO SEQUENCE USING TWO ENCODERS AND STATISTICAL ANALYSIS

摘要

PROBLEM TO BE SOLVED: To improve a picture quality of an encoded video sequence while obtaining high compressibility by providing a real time VBR video encoding system.;SOLUTION: In a method, system and computer program product for more adaptively encoding a sequence of video frames in real time by means of hardware, software or combination thereof, a first encoding subsystem analyzes the sequence of the video frames to derive information on at least one characteristic such as motion statistics, non-motion statistics, scene change statistics or scene fade statistics. The collected information may be also an intra-frame characteristic or an inter-frame characteristic. A control processor is coupled to the first encoding subsystem to automatically analyze the collected information in real time and dynamically generates a set of control parameters. A second encoding subsystem coupled to the control processor encodes each frame of the sequence of the video frames by using the corresponding set of the control parameters.;COPYRIGHT: (C)2004,JPO
