I want to know the answer to the following question:
How many years did it take Blu-ray and HD-DVD players to duplicate MUSE technology?
All the background I'm provided with is that "In 1991, several manufacturers announced specifications for what would become known as MUSE LaserDisc, representing a span of almost 15 years until the feats of this HD analog optical disc system would finally be duplicated digitally by HD DVD and Blu-ray Disc.". Is that enough to answer the question?
