Abstract
A method for efficiently decoding a video signal is disclosed. The method for decoding a video signal based on fine granularity scalability (FGS) includes acquiring picture identification information indicating a reference picture of a current block, and decoding the current block using the reference picture. A base layer reference picture and an enhanced layer reference picture corresponding thereto have the same picture identification information. Accordingly, it is possible to minimize a problem caused in a procedure for decoding a video signal due to transmission error.

1-11. (canceled)
A method for managing a reference picture with a decoder, comprising:
- storing a decoded picture in a buffer, the decoded picture including quality base picture and quality enhanced picture;
- first marking the quality base picture and the quality enhanced picture as a reference picture;
- second marking the quality base picture as distinct information, the distinct information representing information to differentiate the quality base picture from the quality enhanced picture;
- managing the quality base picture and the quality enhanced picture using an adaptive memory management method or a sliding window method,
- wherein the quality enhanced picture has an image quality higher than the quality base picture.
An apparatus for managing a reference picture, comprising:
- a decoded picture buffer storing a decoded picture,
- first marking the quality base picture and the quality enhanced picture as a reference picture,
- second marking the quality base picture as distinct information, and
- managing the quality base picture and the quality enhanced picture using an adaptive memory management method or a sliding window method,
- wherein the decoded picture includes quality base picture and quality enhanced picture, and the quality enhanced picture has an image quality higher than the quality base picture. and the distinct information represents information to differentiate the quality base picture from the quality enhanced picture.
