Satellite Digital Audio Broadcast Co., Ltd, better known and traded as St.GIGA, was a Japanese satellite radio company founded on April 2, 1990 and owned by WOWOW from 1990 to 2001 and WireBee Inc. from 2001 to 2006. They were most known for their "Tide of Sound" broadcasts, which were recordings of nature sounds, and the Satellaview, a peripheral for Nintendo's Super Famicom that allowed the playing of games via satellite broadcasts until the service was discontinued on June 30, 2000. They were also known as the first digital satellite radio station in the world. In 2001, the company, facing bankruptcy, merged with WireBee Inc., a Japanese radio station provider, and was eventually renamed Club COSMO before their licensing rights were sold to World Independent Networks Japan, Inc. and WireBee went bankrupt as well. Their slogan was ""I'm here." "I'm glad you're there."".
Visuals: On an azure, static wave-like background, there is a 3D, metallic version of St.GIGA's logo shimmer from left-to-right.
Variants:
Sometimes, the St.GIGA logo would be accompanied by a text box announcing that the program was about to begin and asking players to wait. The logo's animation occasionally loops until the program officially begins.
On the "JO33-BS-TDM1" warning screen seen before downloaded broadcasted data was loaded, the St.GIGA logo comes down from the top of the screen before shimmering.
Technique: Simple shining effects.
Audio: A Super Mario-esque "ka-ping!" sound, sometimes also accompanied by the beginning of the SoundLink game's audio broadcast.
Audio Variants: The warning screen variant has an eight-note synth string jingle accompanied by the aforementioned "ka-ping!" noise at the end.
Availability: Apart from the warning screen variant, which was used from April 1995 to June 30, 2000, this logo was only seen before a SoundLink game, such as Satellawalker 1 and 2, BS The Legend of Zelda: Ancient Stone Tablets and BS F-ZERO Grand Prix, or a radio program was about to begin or, occasionally with SoundLink games, had ended.
Visuals: On a black background, there is a picture of St.GIGA's broadcasting headquarters at night in the center of the screen and, to its left, is white sideways text reading "JO33-BS-TDM1" (the callsign for one of their data broadcasting transmitters) while, at the bottom of the picture, is white Hiragana text informing players that the transmitted data should only be used for its intended purpose. A 3D, metallic version of St.GIGA's logo comes down from the top of the screen, stopping above the warning text before shimmering.
Technique: Sprite animation.
Audio: An eight-note synth string jingle accompanied by a Super Mario-esque "ka-ping!" noise at the end.
2nd Screen (Mid/Late 1990s-June 30, 2000)
Visuals: The screen fades in to see, on a black background, white text reading "JO23-BS-TDM1" (the callsign for another one of their data broadcasting transmitters), which is above more text reading "St. GIGA". Further down, the same Hirigana warning text from the main warning screen is seen in the same stylization.
Technique: A still, sprite-based graphic.
Audio: Almost exactly like the main warning screen's synth string jingle, but is one note shorter and the "ka-ping!" sound plays earlier.
Availability: This warning screen was only seen before downloaded broadcasted data was being loaded, apparently usually during evening hour Satellaview broadcasts, two examples being a broadcast of BS Super Mario USA Dai-4-kai and the broadcasts of both parts of Satellawalker 2.
