    • A method of and an apparatus for predicting discrete cosine transform coefficients. A discrete cosine transform coefficient prediction method and apparatus performs a discrete cosine transform on a row and column of pixel blocks nearest to a transform coefficient to be predicted in a discrete cosine transform block to be predicted among pixel blocks adjacent to the discrete cosine transform block to create a prediction coefficient for the transform coefficient to be predicted, and predict the transform coefficient to be predicted using the created prediction coefficient. By using prediction coefficients with higher correlation to a transform coefficient of a discrete cosine transform block to be predicted, an image may be efficiently compressed.

    • Provided is a scalable encoding method, apparatus, and medium. The method includes: encoding a base layer and encoding a first enhancement layer and a second enhancement layer in a frame having the base layer; and generating an encoded frame by synthesizing the encoded results. Accordingly, only if the loss of the encoding frame is not as great as the encoded first enhancement layer is damaged, a case where speech restoration with respect to partial frequency bands must be given up does not occur. Furthermore, since an encoder divides the second enhancement layer into a plurality of layers in a horizontal or vertical direction, considering a distribution pattern of data belonging to the second enhancement layer and first encodes a layer in which lots of data are distributed among the divided layers, loss of audio information can be minimized even if a portion of the encoded second enhancement layer is damaged.
    • 提供了可扩展的编码方法,装置和介质。 该方法包括:在具有基本层的帧中编码基本层并对第一增强层和第二增强层进行编码; 以及通过合成编码结果来生成编码帧。 因此,只有当编码帧的损失不如编码的第一增强层损耗那么大时,不会发生关于部分频带的语音恢复的情况。 此外,由于编码器在水平或垂直方向上将第二增强层划分为多个层,考虑属于第二增强层的数据的分布模式,并且首先编码在划分层之间分布有大量数据的层 即使编码的第二增强层的一部分被损坏,音频信息的丢失也可以被最小化。
