In 1991, several manufacturers announced specifications for what would become known as '''Hi-Vision LD''', representing a span of almost 15&nbsp;years until the feats of this HD analog optical disc system would finally be duplicated digitally by [[Comparison of high definition optical disc formats|HD DVD and Blu-ray Disc]]. Encoded using [[NHK]]'s [[Multiple sub-Nyquist sampling encoding|MUSE]] "Hi-Vision" analog HDTV system, MUSE discs would operate like standard LaserDiscs but would contain high-definition 1,125-line (1,035&nbsp;visible lines; [[Sony HDVS]]) video with a 16:9 aspect ratio. The MUSE players were also capable of playing standard NTSC format discs and are superior in performance to non-MUSE players even with these NTSC discs. The MUSE-capable players had several noteworthy advantages over standard LaserDisc players, including a red laser with a much narrower wavelength than the lasers found in standard players. The red laser was capable of reading through disc defects such as scratches and even mild disc rot that would cause most other players to stop, stutter or drop-out. Crosstalk was not an issue with MUSE discs, and the narrow wavelength of the laser allowed for the virtual elimination of crosstalk with normal discs.

To view MUSE-encoded discs, it was necessary to have a MUSE decoder in addition to a compatible player. There are televisions with MUSE decoding built-in and set-top tuners with decoders that can provide the proper MUSE input. Equipment prices were high, especially for early HDTVs which generally eclipsed US$10,000, and even in Japan the market for MUSE was tiny. Players and discs were never officially sold in North America, although several distributors imported MUSE discs along with other import titles. ''[[Terminator 2: Judgment Day]]'', ''[[Lawrence of Arabia (film)|Lawrence of Arabia]]'', ''[[A League of Their Own]]'', ''[[Bugsy]]'', ''[[Close Encounters of the Third Kind]]'', ''[[Dracula (1992 film)|Bram Stoker's Dracula]]'' and ''[[Chaplin (film)|Chaplin]]'' were among the theatrical releases available on MUSE LDs. Several documentaries, including one about [[Formula One]] at Japan's [[Suzuka Circuit]] were also released.

LaserDisc players and LaserDiscs that worked with the competing European [[HD-MAC]] HDTV standard were also made.<ref>{{cite web |first1=J.B. |last1=Tejerina |first2=F. |last2=Visintin |url=https://tech.ebu.ch/docs/techreview/trev_254-tejerina.pdf |title=The HDTV demonstrations at Expo 92 |work=EBU Technical Review |date=Winter 1992}}</ref>
