KAM-SD-2AES-MUX Links and Web Pages
MUX Web Page
Use the MUX (multiplex) web page ( Figure 28 on page 47 ) to:
• Delete unwanted embedded audio groups from the SDI input signal or
delete all horizontal ancillary data (HANC) in all audio groups, and
• Insert or replace audio groups in the SDI video output with external
AES inputs that have been configured in the Audio Processor.
Note The audio channel pairs available to each Mux Group below are determined
by the Audio Channel Pairing web page (see
page 52 ).
Note The Kameleon multiplexing circuit assumes there are no gaps between
Groups in the input SDI video signal. If there are gaps, and one or more
groups are inserted or replaced, all input Groups after the gap will be
removed.
Figure 25 depicts the multiplexing of the processed audio streams into the
SDI video output stream based on the selections made on the Mux web
page in
Figure 28 on page 47 .
Figure 25. Multiplexing into the SDI Stream
The Mux web page provides two functions: Group Deletion and Group
Replacement. Each of these functions depends on the presence of
embedded audio groups in the incoming SDI video stream and the external
AES audio inputs.
