Before being compressed for transmission, the video stream is reformatted for the standard Japanese phone's 320-by-240 pixel screen.
视频流在压缩传输之前必须先格式化以适应日本手机320乘以240像素的标准屏。
If the transform matrix type is a half pixel matrix, then the method includes applying a factorization technique to decode the bit stream corresponding to the half pixel matrix.
若该变换矩阵的类型是半像素矩阵，则该方法应用因子分解技术解码与该半像素矩阵对应的比特流。
The technology of video stream transcoding can be divided into two types: spatial domain(pixel-domain) and compressed domain(DCT-domain).
目前的视频流转码大致可以分为空域（像素域）转码和压缩域（DCT域）转码两种方法。
