The function of the components
4-14
In the location with fixed Events (location number “0”), one single cell
transmitter transmits all Storage Events once via the streaming method,
usually overnight (stationary download). The receivers store these
Storage Events of location “0”.
In the locations with variable Events (location numbers from “1” to max.
“63”), a cell transmitter permanently stores and transmits all Storage
Events of a cell. Receivers entering this cell receive these Storage Events
and download them (mobile download).
Live Events Live Events typically come from a CD, DVD, videocassette or another sound
source such as a wireless microphone. The corresponding audio sources
(CD or DVD player, video recorder or the receiver of a wireless microphone)
are directly connected to the audio inputs of the cell transmitters. Each cell
transmitter has four audio inputs to which you can connect four mono
sound sources or two stereo sound sources or one stereo sound source and
two mono sound sources.
Transmitting the Events to the antennas
The cell transmitters, which cannot be seen by the visitors, transmit the
Events to the antennas.
In locations with variable Events, all Events are converted into multiplexed
transport streams (MTS) . Each cell transmitter transmits two independent
MTS (MTS “0” and MTS “1”) and requires two separate antennas (antenna
“0” and antenna “1”) connected in series. Both MTS can contain Storage
Events, but only MTS “0” can contain Live Events. MTS “0” is transmitted
by the active antenna “0” and MTS “1” is transmitted by the active
antenna “1”. Each MTS (each antenna) requires an RF channel of its own.
One MTS can contain Storage Events with a total playing time of approx.
600 seconds (10 minutes). This value is reduced if, apart from Storage
Events, this MTS contains Live Events (see “Assigning an MTS for a
category to an Event” on page8-65). It is, however, possible to
successively transmit several MTS (up to four) to a receiver.
One MTS only transports Events of one category. It is not possible to mix
Events from different categories and transmit them via the same MTS. You
therefore require at least one antenna in each cell for every category
offered.
The frequency on which the Event data is transmitted from the antennas
to the receivers is set via the software (see “Selecting the RF channel” on
page 8-41 and “RF channels” on page 18-9). This also applies for the
transmitting power and thus the range (see “Setting the transmitting
power” on page 8-42).
In the location with fixed Events (location “0”), only Live Events are
“packed” into MTS; Storage Events, in contrast, are transmitted via the
streaming method (stationary download).
