SPECIAL VLSI FOR VIDEO DATA CONVERSION
Read the full article
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.
