Abstract
A video data run length decoding apparatus is disclosed. The aparatus includes a run length decoder for analyzing a run value of a coded video data, generating a run value, and alternately outputting an interval of a 8-clock signal in which there is a data and another interval of a 8-clock signal in which there is not a data using a gap clock signal, a reverse zig zag and dequantizer for processing a data from the run length decoder based on the reverse zig zag and dequantization operation, and a reverse discrete cosine converter for processing a data outputted from the reverse zig zag and dequantizer, two times, based on the reverse discrete cosine conversion and outputting a two-dimensional video data, thereby decreasing the number of gates of a decoding apparatus and implementing a high speed system by alternately outputting an interval in which there is a data and another interval in which there is not a data using a gap clock signal generator in a run length decoder for a video data run length decoding apparatus.
