METHOD OF ENHANCING ENTROPY-CODING EFFICIENCY, VIDEO ENCODER AND VIDEO DECODER THEREOF |
摘要 |
<p>A video encoder and encoding method are provided. The encoder includes a frame-encoding unit that generates at least one quality layer from an input video frame; a coding-pass-selection unit that selects a coding pass with reference to a second coefficient of a lower layer adjacent to a current layer included in the at least one quality layer, the second coefficient corresponding to a first coefficient of the current layer; and a pass-coding unit that encodes the first coefficient without loss according to the selected coding pass.</p> |
