11 Decoders
Decoders are configured using the Decoding applications in the dashboard. When a decoder has been configured and
enabled it will deliver decoded video and audio through the SDI output connectors. The input to the decoder comes from
one of the input interfaces in the chassis and is delivered to the decoder over the backplane.
11.1 Configuration Flow
Parts of the Configuration of a Decoder is done through reusable Profiles. This way the same decoder configuration can
be applied to multiple services. If a Profile is altered, the change is automatically applied to all the services using the
Profile.
Profiles define parameters that are likely to be identical for many services. In contrast,
service specific
parameters are not
configured through Profiles but rather on an individual service level. Examples of service specific parameters are which
physical SDI output connector is used, audio output format etc.
The starting point of building a service is to first define the necessary profiles, alternatively reuse existing Profiles.
Typical Service Configuration Sequence:
Step 1
– Define one or more Video Profiles
Step 2 - Select which input service to decode
Step 3 - Configure Service using specific module and output connector, and a profile defined
above.
Step 4
– Repeat from Step2 to configure multiple services

11.2.1 Decoder Video Profile
The Decoder Video Profile defines the
output
characteristics of a video component.
