    Wikipedia schreibt unter dem Begriff Worldspace:
    WorldSpace ist ein gescheitertes digitales Satellitenradionetzwerk. Es versorgte Afrika ganzflächig und darüber hinaus Teile Asiens und Europas. Es bestand aus zwei Satelliten, AfriStar und AsiaStar. Es standen pro Satellit 50 Kanäle zur Verfügung, die für digitale Radioprogramme, aber auch Multimediadienste genutzt werden konnten. 2008 beantragte Worldspace Insolvenz.

    Ein Radio-Set besteht aus einem portablen Satellitenempfänger und einer handtellergroßen Satellitenantenne, wobei diese auf eine der beiden Satelliten AfriStar und AsiaStar ausgerichtet werden musste.

    Wikipedia writes under 1worldspace:
    1worldspace, known for most of its existence simply as 'WorldSpace', is a defunct satellite radio network.
    Before filing for bankruptcy in October 2008, 1worldspace employed two satellites and broadcast 62 channels.

    Users purchased receivers compatible with the L-Band frequency in order to access the system. The radio receiver processed, decoded and descrambled the signals to allow users to receive programming content. The company’s broadcast frequency and satellites required a special receiver design incorporating either a small patch antenna measuring approximately 6 to 8 cm (2.4 to 3.2 inches) which folded neatly into the receiver unit or a similarly sized omni-directional antenna mounted on the car rooftop. Each receiver was individually addressable via a unique identifier that could be used to unlock specially coded audio or multimedia signals. This capability provided the flexibility to deliver free, subscription and/or premium services to consumers.
