On the Digital and Coding Compression of TV Signal
Cuihua Li · Journal of Hefei University · 2005
Owing to enormous information of the image,and because of the memory and transmission of the picture,condensation of image signal is demanded.The purpose of condensation is to use as few as codes to denote and construct the original image.The means of coding compression is as follows:sample frequency coding reduction,different predictive coding,linearity transform coding,discrete cosine transform.
