NOTE

  • In this subclass, the following terms or expressions are used with the meaning indicated:
    • "broadcast" is simultaneous distribution of identical signals to plural receiving stations. The term "broadcast" does not include distribution to receiving stations which is controlled by requests or responses from the receiving stations;
    • "broadcast information" covers all kinds of information distributed by broadcast systems;
    • "broadcast-related information" is information required by services provided via broadcast systems, other than broadcast information;
    • "broadcast time" is a time when particular broadcast information exists and is available;
    • "broadcast channel" is a channel via which broadcast information is distributed, e.g. carrier waves, time slots, cables or wireless broadcast service areas;
    • "broadcast space" is either a set of broadcast channels in which particular broadcast information exists and is available or a geographical area determined by the set of broadcast channels;
    • "broadcast space-time" is space-time determined by broadcast space and broadcast time in which particular broadcast information exists and is available;
    • "broadcast system" is a system which consists of transmitter, transponder and receiver for broadcast;
    • "broadcast-related system" is a system which is directly affected by generation, broadcast, reception or use of broadcast information;
    • "broadcast service" is a service directly provided by a broadcast system, i.e. distribution service of broadcast information;
    • "broadcast-related service" is a service provided by broadcast-related systems;
    • "A with a direct linkage to B" means that A directly affects B or that A is directly affected by B.
WARNING

  • In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
