Abstract
Provided are an apparatus and method of encoding a moving picture. An input original video signal is delayed and stored in a memory as a video signal for motion estimation (a video signal of a previous frame). Then, a motion estimation is performed using a video signal of a current frame and the reference image (the video signal of the previous frame). Accordingly, a decoding module/decoding processor for constructing a reference image in an existing encoder is eliminated.
Claims17
An apparatus of encoding a moving picture, comprising:
- an encoding part for compressing and coding a video signal;
- a video storing part for storing an inputted original video signal as a reference image for a motion estimation and encoding;
- and
- a motion estimation part for performing a motion estimation using the input video signal stored in the video storing part as a reference image for the motion estimator.
An apparatus of encoding a moving picture, comprising:
- an encoding part for compressing and encoding a video signal;
- a video storing part for storing an original video signal of a previous frame as a reference image for a motion estimation and encoding of a video signal of a current frame;
- an image filter for filtering the video signal stored in the video storing part;
- and
- a motion estimation part for performing a motion estimation using the original video signal of the previous frame, which is stored in the video storing part, as the reference image for the motion estimation.
A method of encoding a moving picture, comprising:
- compressing and encoding an input video signal;
- substituting the inputted original video signal for a decoded video signal of the encoded video signal and storing the substituted video signal as a reference image for an encoding of a next frame;
- performing a motion estimation using the stored original video signal of a previous frame as a reference image for a motion estimation;
- and
- providing the stored original video signal of the previous frame for compressing and encoding a video signal of a current frame,
- whereby a decoding module/decoding processor is eliminated by a process of substituting the original video signal for a decoded video signal.
