SPECIAL VLSI FOR VIDEO DATA CONVERSION
Annotation
The new approach to distribution of a compression video content with simultaneous use of two alternative compression technologies of moving images is considered: 1) on the basis of three-dimensional discrete cosine transformation (this technology is not standardized for today) and 2) on the basis of two-dimensional discrete cosine transformation of the digital television signal (realized in standards MPEG-2, MPEG-4 and Н.264). Within the limits of the specified approach the method of fast transcoding of the main video data stream compressed by three-dimensional discrete cosine technology of transformation in a compression stream of MPEG-2 standard is proposed.
