    • Provided is a method of encoding FGS layers by using weighted average sums. Method includes calculating a first weighted average sum by using a restored block of n enhanced layer of a previous frame and a restored block of a base layer of a current frame; calculating a second weighted average sum by using a restored block of n enhanced layer of a next frame and a restored block of a base layer of the current frame; generating a prediction signal of n enhanced layer of the current frame by adding residual data of (n 1) enhanced layer of the current frame to a sum of the first weighted average sum and the second weighted average sum; and encoding residual data of n' enhanced layer, which is obtained by subtracting the generated prediction signal of n enhanced layer from the restored block of n' enhanced layer of the current frame.
    • 提供了使用加权平均和编码FGS层的方法。 方法包括通过使用先前帧的n增强层的恢复块和当前帧的基础层的恢复块来计算第一加权平均和; 通过使用当前帧的下一帧的n增强层的恢复块和基础层的恢复块来计算第二加权平均和; 通过将当前帧的(n 1)增强层的残差数据添加到第一加权平均和与第二加权平均和之和来生成当前帧的第n增强层的预测信号; 并且对通过从当前帧的n'增强层的恢复块中减去所生成的n增强层的预测信号而获得的n'增强层的残差数据进行编码。
