反余弦

Inverse hyperbolic cosine -- in radians !!!

反双曲线余弦--以弧度为单位！！！

Based on the characteristics of AVS algorithms, hardware architectures of variable length decoding module, inverse integer cosine transform module and in-loop deblocking filter module were developed.

同时根据AVS算法特点，给出了变长解码模块、反整数余弦变换模块和环路滤波模块的硬件实现结构。

MDCT (Modified Discrete Cosine Transform) and IMDCT (Inverse Modified Discrete Cosine Transform) are two of the most complex computation modules.

改进离散余弦变换与其反变换是当今主流音频压缩标准中普遍采用的时频变换单元，也是计算量最密集的模块之一。

The layered video decoding system comprises a base layer decoder for receiving and decoding a base layer video stream; and an enhancement layer decoder for receiving an enhancement layer video stream and the decoded base layer stream, and generating a decoded enhanced video output, wherein the enhancement layer decoder includes: a plurality of inverse discrete cosine transform /IDCT modules; and a selection system for selecting one of the IDCT modules.

分层视频译码系统包括：基本层译码器，用于接收和译码基本层视频流；和增强层译码器，用于接收增强层视频流和所译码的基本层流，并生成译码的增强的视频输出，其中该增强层译码器包括：多个反离散余弦变换模块；和用于选择其中一个IDCT模块的选择系统。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
