<p>This System compiles different Radio or Television programme inputs. When the entertainment source begins to fade out, an information tape starts and is mixed over the entertainment input. After the actual end of the entertainment input its source will be stopped. When the information input is about to finish, the entertainment source starts and is mixed under the information. After the actual end of the information input its tape drive will be stopped. When the entertainment input ends again, the process as described above will be repeated. The order of various information inputs can be preprogrammed. The entertainment source can be any kind of signal source. Special provisions (such as a Music Play Back Counter) can be applied. The entertainment source can be controlled by Volume Level Indicators, Pilot Tones or External Commands. The whole System is protected against operational errors.</p> |
