MPEG decoder

   Also found in: Wikipedia 0.01 sec.

Software or hardware that decompresses and renders MPEG-encoded data. Because MPEG uses lossy compression, the decoded images are not 100% identical to the original. In most cases however, the differences are not easily detectable. See MPEG.

Sigma Designs (Nasdaq:SIGM), has announced that NEC Corporation has selected Sigma's MPEG decoder EM8470 for incorporation into its new VALUESTAR T series of multimedia consumer PCs.
Then the demodulator converts the analog signals to digital signals and reduces the signals to baseband signals with central frequency at 10MHz, which are absolutely digital signals here, the MPEG decoder converts these digital signals to analog signals, the analog signals here are still interlaced scanning signals which will become progressive scanning signals after the interpolation algorithm of back-end image processing.
