I.McIC: A single-chip MPEG2 video encoder for storage

MPEG2 encoding is done mainly by distributors and publishers using professional equipment too expensive for the consumer market. I.McIC is a video encoder for this market, in particular for storage applications where higher bit rates can he tolerated (5-15 Mb/s) compared with bit rates for transmission (1.5-8 Mb/s). I.McIC operates in MPEG ML@SP mode and offers good video quality at 5 Mb/s and excellent quality at 10 Mb/s. For consumer storage applications, the video signals to be encoded might not be as clean as typical studio standards. Therefore, noise reduction is an integral part of I.McIC. I.McIC can share 16 Mb DRAM with an MPEG2 video decoder, organized as 4 times 4 Mb devices with 60 ns access. It can handle both 50 Hz and 60 Hz video sources. To interface to a video source, I.McIC uses a line-locked clock generated by the A/D converter and running at 27 MHz.
