Is there a archive of tv shows that aired on tv tokyo?

Hi everyone. Im looking for a high quality archive of shows that aired on tv tokyo. There is a tv series called transformers prime. And the japanese airing had some bonus stuff not included in the US release.

I bought the japanese dvd. But the quality is terrible compared to a screenshot i found of the original airing. I also bought the series on niconico and Amazon Prime JP. But again the quality is terrible.

So i was wondering is there some sort of archive or database of original tv airings? And does anyone have any idea where i can find it?
