METHOD AND APPARATUS FOR CONTROLLING VIDEO BITRATE |
| 摘要 |
The present invention may improve image quality of a video image while maintaining fixed bitrates by discrete cosine transforming a pixel value a current frame from a video signal, calculating a complexity of a current frame based on a transform coefficient value of a current frame according to the discrete cosine transform, obtaining a quantization parameter of a current frame using the complexity of a current frame, and controlling bitrates of a video image. |
