Abstract
Disclosed is a method for scalably encoding and decoding a video signal. An enhanced layer having a higher spatial resolution is predicted and encoded based on an enhanced layer having a relatively lower spatial resolution. Then, the encoded enhanced layer is decoded, thereby improving a coding efficiency.
Claims20
A method for encoding a video signal, the method comprising the steps of:
- generating a second bit stream by encoding a video signal in a predetermined scheme;
- and
- generating a first bit stream by scalably encoding the video signal,
- wherein each of the first and second bit streams includes a first layer and a second layer for compensating for an error occurring in an encoding procedure, and at least a part of the second layer of the first bit stream is predicted by using prediction data generated based on the second layer of the second bit stream.

A method for decoding an encoded video bit stream, the method comprising the steps of:
- decoding a first bit stream of received bit streams, which have been scalably encoded and include a plurality of vide sequences;
- and
- decoding a second bit stream of the video bit steams,
- wherein each of the first and second bit streams includes a first layer and a second layer for compensating for an error occurring in an encoding procedure, and at least a part of the second layer of the first bit stream is decoded based on the second layer of the second bit stream.
