    Abstract: A device and a method for generally extracting FGS(Fine Granular Scalability) from SVC(Scalable Video Coding) video with user preference are provided to supply an SVC bit stream having the FGS data according to a consumption environment. An R(Rate)-D(Distortion) data extractor(110) extracts R-D data of more than one space layer by analyzing a bit stream. A user preference collector(120) collects user preference for each space layer. A determination engine(130) determines an optimal bit rate for each space layer by using the bit rate and the user preference. A scaling engine(140) excludes FGS data not corresponding to the optimal bit rate for each space layer.

    Abstract: A scalable video coding encoder with an adaptive reference FGS(Fine Grain SNR Scalability) and FGS motion refinement method, the encoder, and a method for encoding and decoding in the same are provided to increase higher encoding efficiency of the encoder by determining a prediction signal of the FGS layer block according to scale element values of the FGS layer and determining the scale elements according to the residual signals of the FGS layer block. A scalable video coding encoder comprises a prediction signal determining part(1010), and a scale element determining part(1020). The prediction signal determining part determines a prediction signal of the FGS layer block according to the scale element value of the FGS layer when the interlayer prediction is not made among the foundation layer, the former layer, and the present layer. The scale element determining part determines the scale element used when predicting the FGS layer block corresponding to the FGS layer block on the basis of the residual signals of the FGS layer block.
