The Sigma Designs Hollywood Plus MPEG Decoder is a hardware device that was used in the late 1990s and early 2000s to accelerate the decoding of MPEG-1, MPEG-2, and sometimes MPEG-4 video streams. This hardware was used primarily to offload the processing of video decoding from the CPU to the Hollywood Plus MPEG decoder card, which allowed for smoother playback of high-quality video, such as DVDs, on PCs. It was a popular solution before integrated GPU hardware decoding became commonplace in modern graphics cards.
