VIDEO ENCODING AND DECODING METHODS AND APPARATUSES |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide video encoding and decoding methods and apparatuses which are capable of improving efficiency of encoding a luminance component video signal by predicting information on various encoding modes of the luminance component video signal by using a result obtained by encoding a color difference component video signal. <P>SOLUTION: The present invention relates to video encoding and decoding methods and apparatuses in which a block mode and an intra-prediction mode of a luminance component video signal are predicted from a previously encoded and recovered color difference component video signal, and the predicted block mode and the predicted intra-prediction mode are used to encode the luminance component video signal. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
