BROADCAST COMMUNICATION (multiplex communication H04J; pictorial communication aspects of broadcast systems H04N)
NOTE
-

1. 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.
2. In this subclass, multi-aspect classification is applied, so that subject matter characterised by aspects covered by more than one of its groups, which is considered to represent information of interest for search, may also be classified in each of those groups.
