Abstract (en)

[origin: WO2006078107A2] Disclosed herein is a Fine Granularity Scalability (FGS)-based video encoding and decoding method and apparatus capable of controlling deblocking. In the video decoding method according to the present invention, original video data is received and a base layer is generated based on the original data. Next, the difference between the original data and data that is obtained by reconstructing the base layer and deblocking the reconstructed base layer is obtained, thus generating an enhancement layer. Then, a reconstructed frame is generated based on the data that is obtained by reconstructing the enhancement layer, and data that is obtained by reconstructing and deblocking the reconstructed base layer. Finally, the reconstructed frame is deblocked at a lower intensity than that of deblocking performed in the first two steps.
