摘要
The present invention is, while minimizing picture quality degradation in the H.264 video encoder structure of the H.264 video encoder for encoding video from the high-speed. ; This invention is of high speed to minimize the required absolute implemented through estimating the Rate-Distortion Optimization-Feed Back and perform several times for Rate-Distortion Optimization which DCT-IDCT operation on the high-definition encoded in the H.264 H.264 video coding the encoding is done so. ; Check-B- slice unit for video compression encoding device of the present invention, performing a check on the current frame data slice B-; Inter prediction mode, the maximum bit value computing section for obtaining a predicted bit value by performing motion estimation and motion compensation with respect to the inter mode using the largest block division; At least an intra mode prediction bit value for obtaining a predicted bit value by performing motion estimation and motion compensation with respect to an intra mode block split using the minimum calculation unit; Linear parameters and the linear prediction for bit values using the statistical values to obtain the prediction value with respect to the bit mode other than the intra mode, inter mode, and a minimum of divided blocks of the maximum division block estimation; Mode determination unit for determining the appropriate encoding mode by comparing the maximum inter-mode prediction bit value calculation unit, an intra mode prediction bit minimum value calculation unit and the linear prediction bit estimation additional bit calculated predicted value; And it characterized in that it includes an encoding for encoding the current frame data determined by the mode in the mode determining unit. ; H.264, Rate-Distortion Optimization, DCT, Feed-Back
