Method and device for encoding/decoding video signals using base layer |
摘要 |
The present invention relates to encoding and decoding a video signal by motion compensated temporal filtering. In one embodiment, a first sequence of frames are decoded by inverse motion compensated temporal filtering by selectively adding to a first image block in the first sequence image information, the image information being based on at least one of (1) a second image block from the first sequence and (2) a third image block from an auxiliary sequence of frames. |

1. A method of decoding a video signal, comprising:
separating a base layer stream and an enhanced layer stream from the video signal; obtaining prediction information indicating whether inter-layer prediction is used for a current block in an enhanced layer, the inter-layer prediction is to predict the current block by using a base layer; obtaining macroblock information of the current block using the enhanced layer stream; obtaining motion prediction information using the macroblock information, the motion prediction information indicating whether motion information of the current block is obtained using motion information of a reference block; obtaining motion information of the current block using the motion prediction information; and decoding the current block by using the motion information of the current block. |
