    摘要： An MPEG-4 encoder utilizing an H.263 multimedia chip. The MPEG-4 encoder includes a DC (Direct Current) predictor for predicting a DC component of the image frame encoded by an H.263 standard upon receiving a prescribed MPEG-4 quantization value, and an MPEG-4 reconstruction image memory for converting the H.263 reconstruction image into an MPEG-4 reconstruction image, and storing the MPEG-4 reconstruction image. The MPEG-4 encoder removes spatial redundancy from source image data entered in frame units using a prescribed H.263 quantization value, predicts a DC component of an image frame having no spatial redundancy using a prescribed MPEG-4 quantization value, performs a VLC (Variable Length Coding) process on the image frame using the predicted DC component, and outputs the VLC-processed image frame in the form of an MPEG-4 bit stream. The MPEG-4 encoder reconstructs the image frame having no spatial redundancy, stores the reconstructed image frame, converts the reconstructed image frame into an MPEG-4 frame, stores the MPEG-4 frame, compares the stored image frame with a newly-entered next frame, and removes temporal redundancy according to a result of the comparison.

    摘要： A H.263/MPEG video encoder using an average histogram difference, and a method for controlling the same are disclosed. The H.263/MPEG video encoder generates a reference image frame for encoding a subsequent input image frame N based on a current input image frame N−1 which is performed by a DCT (Discrete Cosine Transform) and quantization operations for outputting a video stream and a quantized signal. Here, the quantized signal is decoded by an inverse quantization and inverse discrete cosine transform (IDCT) operations. Also, the encoder comprises a mode selection unit for selecting a first mode in which motion estimation/compensation operations are not performed, if the subsequent image frame N is relatively heavily changed from the reference image frame, after the subsequent image frame N is compared with the reference image frame to remove a temporal redundancy therefrom.
