| titleOfInvention | Compression coder and / or decoder of video signal and method thereof |
| abstract | The present invention discloses a compression encoder and / or decoder of a video signal and a method thereof. Disclosure of Invention According to an embodiment of the present invention, a discrete transform unit for discretely transforming an input image signal to provide discrete transform coefficients, an initial quantizer for providing initial quantized data by quantizing discrete transform coefficients using an initializing quantization matrix, and a plurality of initial quantized data Initial quantization by a code amount adjuster that provides a quantization step size that outputs the result closest to the target code amount among the respective code amounts obtained by quantization in parallel using a quantization step size Including a real quantizer that quantizes the compressed data to provide compressed data, and when applied to a digital video cassette recorder, it is possible to perform image processing on a screen basis by compression encoding and decoding on a screen (intra picture) unit. Apply to In this case, the video signal is compressed, encoded and decoded so as to comply with the MPEG-2 standard, and is compatible with all devices using MPEG. |
