“The Satellaview system was developed and released by Nintendo to receive signals broadcast from satellite TV station WOWOW's satellite radio subsidiary, St.GIGA. St.GIGA was responsible for file server management, maintenance, and vocalization for "SoundLink" games. Nintendo data broadcasts were given a fixed time slot known as the Super Famicom Hour (スーパーファミコンアワー?) during which scrambled Satellaview-related data was streamed via radio waves to be unscrambled by St.GIGA's "BS digital hi-vision TV" (ＢＳデジタルハイビジョンテレビ BS Dejitaru HaiBijon Terebi?). As a subscription-based station for ambient and New Age music, St.GIGA listeners were already equipped with "BS tuners" prior to St.GIGA's contract with Nintendo”
