In this article, the authors proposed a variable length encoder to suppress the data amount of digital video signals after high efficiency encoding without inviting the picture quality degradation of reproducing pictures.Abstract:
PURPOSE:To provide a high efficiency encoder capable of suppressing the data amount of digital video signals after high efficiency encoding without inviting the picture quality degradation of reproducing pictures. CONSTITUTION:'0' run length encoding is performed to blocked digital video data in a data separation circuit 11 and they are separated into run length data and coefficient data. After the '0' run length encoding is performed to the separated run length data in a data separation circuit 12 and '1' run length encoding is performed to the separated coefficient data in a data separation circuit 13, variable length encoding is performed to the respective data in variable length encoders 14 and 15.read more
