AUDIO FOLLOW VIDEO
AUDIO FOLLOW VIDEO function is also known as audio follow video. This means that the audio source will switch
with the corresponding video input, and actually follow the T-bar function. The active audio is de-embedded and sent
to the audio output terminals for processing and/or audio levelling/ and or adding more audio sources. The resulting
audio will return and be connected to the audio inputs for the purpose of (re)-embedding the audio to the SDI output.
The selection of the audio groups determines the SDI channel that the audio will be embedded to exactly.
AUDIO FOLLOW VIDEO function is primarily used in talk show or live news broadcasting. Voices of different guests
are directly collected by the corresponding cameras, thus, when the program director switches between different
guests, the video is switched at the same time with voice of the guest during program broadcasting. This function is
definitely an indispensable function during live broadcasting.

The
AUDIO FIXED method, allows a user to manually select which audio input can be matched to the SDI video input
and assigned to the audio output terminals, which is shown in the example below:
The table below illustrates that the sound of video input 1 is used for all individual video inputs.

The
AUDIO FIXED function is primarily used during big (concert) events and (wedding) parties. One camera picks up
the audio of the audience and/or ambience of that video input 1, which is assigned to be sent to the audio output. The
other cameras are assigned to this same audio of video input 1. When the operator switches between the video
sources, the sound of video input 1 remains on all the time.
