B.4 Audio Troubleshooting

KudosPro products can process several audio formats: embedded, balanced AES, and
balanced analog as standard, and unbalanced AES if the composite option is fitted.

B.4.1 SD Embedded Audio Problems

In the SD domain, the specification for embedding audio into a video channel is ambiguous.
The ambiguity concerns the packet distribution process applied. Two manufacturers can
comply with the specification and still be incompatible with one other. Because SAM products
often interface with other manufacturers’ equipment, we take care to ensure compatibility.
However, because there are so many manufacturers interpreting the specifications in their
own way, it is difficult for a single manufacturer to be compatible with all other manufacturers.

A packet distribution issue may cause either audio distortion, or “motor-boating”. To test for
this:

•

Apply a known good source that is the same video standard as the problematic
source (you can set up an unused KudosPro channel with a video pattern and test
tone). If the problem is does not occur with a known good source, then it could be due
to a packet distribution compatibility issue.

B.4.2 Testing Audio

As with video, you can test audio by using a process of elimination. The KudosPro products
can handle various formats of audio. If a fault can be isolated to a single format, or perhaps a
particular format is not affected, it is valuable information for the troubleshooting exercise.

Because the KudosPro units are multi-channel, you can use one conversion channel as a test
generator for the other conversion channels. See “Testing Feedback – Two-channel Audio
Processing” on page 171.

Note:

LC2000-IQ/LC4000-IQ units do not have CVBS or unbalanced AES inputs or outputs.

Note:

In the HD domain, the specification is clearly defined and ambiguities do not occur. It is
unlikely that you will encounter any issus in the HD domain, due to the way the audio
embedding is implemented.
