30 Maestro — Channel Branding User Guide
Section 1 — Channel Branding Overview
maximum audio element length, with 16-audio channels, is 30-seconds. An
audio file is played in its entirety unless it is interrupted by a program or
an effect transition. The audio file is configured to play in one of the fol-
lowing modes:
Play Once
The Play Once mode will play the entire audio element once and then will
stop in silence. The element is then removed from Program output by a
transition or a hot take.
Loop
The Loop mode will play the entire audio element constantly looping from
the end of the audio element to the beginning of the audio element. This
mode will continue until the element is removed from the Program output.
Audio files are converted to the internal Channel Branding data format
prior to storage in preparation for playout.
The Maestro Channel Branding will accept and convert the following audio
data formats:
• Windows Audio Format (.WAV)
• Broadcast Wave (.WAV)
Channel Branding audio clips are played using 48-KHz sampling with 16-
bits per sample per channel (which is commonly called CD quality). Exter-
nally-generated audio elements that use more that 16-bits per sample will
be rounded to 16-bits per sample for storage and playout by Ingest.
Animation Sequences and Full-Motion Video
Animation branding elements are still image sequences or motion video
objects that are capable of playout in the Channel Branding. The length of
an animation sequence is determined by the object that is being animated.
An Animation sequence is played in its entire length unless it is interrupted
by a program or an effect transition. The Animation sequence is configured
to play in one of the following modes:
Play Once
The Play Once mode will play the entire animation element once and then
freezes at the last frame. The element is then removed from program output
by a transition or hot take.
Loop
The Loop mode will play the entire animation element continuously
looping from the last frame of the animation element to the beginning
