[Classic] Yu-Gi-Oh! Duel Monsters Remaster

Let us understand the term “remaster”.

Starting February 7th, 2015 at 7:30 JST, the original Yu-Gi-Oh! will be reairing in Japan, but this set of reruns is apparently a “Remaster”, likely meaning a digital remaster of the series (meaning quality enhancement of the original pictures and audio). This does not appear to be a “Yu-Gi-Oh! Kai” thing, merely remastered reruns of Yu-Gi-Oh! for the digital age, and likely the new master “tapes” that any further streaming, DVDs, etc. will be using.
