    Abstract: An apparatus for allocating priority order on each frame in SVC and a method thereof are provided to reduce memory required for storing a distortion value and to decrease complexity in case the distortion value is calculated. An apparatus for allocating priority order on each frame in SVC comprises the followings; a single condition setting unit(410) assuming that an SNR enhancement layer exists in other frame of GOP; an estimating unit(420) estimating an identical distortion value; and a compensation unit(430) compensating the distortion value by reflecting a different rate of size.

    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.
