APPARATUS AND METHOD FOR VIDEO DECODING FOR VIDEO QUALITY ENHANCEMENT OF MOVING PICTURE

摘要

Disclosed are a video decoding apparatus and method for improving video quality, which can cause a video decoder of a terminal having a high-resolution display device improve the video quality of a video having a resolution lower than the display device. The video decoding apparatus includes an image quality enhancement processing unit and a control unit. The image quality enhancement processing unit includes: a resizer and image quality enhancement filters to process different image quality enhancement, whereby the process of image quality enhancement of a decoded video by at least one image quality enhancement filter is selected among the image quality enhancement filters and upscales the processed video by the resizer. The control unit selects at least one of the image quality enhancement filters as image quality enhancement filters to process the image quality enhancement, and sets up a processing sequence by the selection of at least one image quality enhancement filter and the resizer.
