would be used, you can specify a mapped target in the
and it stays the same even if
the external cabling is changed. If the TMAP1 is mapped to T1L, then when the TMAP1
target is specified in a
, it will play out T1L (mono). However, if you change the
mapping of TMAP1 to T2 (stereo), then TMAP1 stays the same in the
, but the output
goes out the second port in stereo. Using this method, the
would not have to be
changed to change the output port target.
Mainly, Target Maps allow network controlled programs to be sent to the same target for all
stations and the stations assign the Target Map to a specific port or target for their use. The
head-end of the program delivery system, does not know what port a station wants the
receiver to use for airing. The program producer communicates to the station what TMAP
port they will use and the station assigns that TMAP to a physical port. For example, The
program producer will use TMAP2 for their program and the station will map that to the
physical port they want to use for the program. If the station wants that program to come out
T1, then they would map TMAP2 to T1. However, another station uses a mono feed and
wants the same program to come out T2R. That station would map TMAP2 to T2R. When
the program is sent, each station would get the same program out the ports they assigned. See
the
section to program the ports.
Digital Ports
The digital ports mirror the analog targets and cannot be addressed separately from the
analog ports. Whatever is played on T1 also is played on Port 1 of the digital outputs (AES-
EBU, SPDIF, Optical). All of the outputs on a target (digital and analog) are always the
same. If two different programs are played out a target on the left and the right, the digital
output ports also have the different programs playing out the left and the right.
Example:
Program 1:
Adventures in Odyssey
Program 2:
Grace to You
Program 1 is sent out T1L and Program 2 is sent out T1R
Program 1 is summed as mono and sent out T1L
Program 2 is summed as mono and sent out T1R
T1L has the summed audio of Adventures in Odyssey program
T1R has the summed audio of Grace to You program
The analog T1L has
Adventures in Odyssey
on the left channel as does the AES-EBU, SPDIF
and Optical output ports as assigned to T1.
The analog T1R has
Grace to You
on the right channel as does the same AES-EBU, SPDIF
and Optical outputs ports assigned to T1.
If you have an AES-EBU input to your board and both channels go to air on a stereo station,
the left channel of your station will have
Adventures in Odyssey
summed to mono and the
right channel will have
Grace to You
summed to mono.
Playlist
The AMR-100-I has a playlist that controls when files are played and what can trigger a file
playback. It also works with live feeds to insert spots and produce relay closures. The playlist
is managed by the AMB-OS User Interface (UI) that transfers programs. Download The
Amb-OS User Interface (UI) software, documentation and the playlist manual at
) to get the complete explanation of the playlist features.
