ENERAL INFORMATION
In the Appear platform, there are two categories of coder modules available. Encoder modules take
uncompressed digital signals from SDI input ports while transcoder modules take compressed digital signals
from the input cards in the unit. The output from all module types are compressed digital signals than can be
routed to any of the output cards in the unit.
Encoding capabilities (HD/SD and the number of channels) of the encoder and transcoder modules can be
changed via options and licenses. These modules are configured separately but have similar video encoding
parameters. The common parameters for encoders and transcoders are described in the Encoder and
Transcoder Parameter Guide.
The Coders view in the Navigation Pane gives a summary of the encoders and transcoders present.
The Coders View contains the following information:
Slot
Slot in which encoder is placed
Type
Type of coder module.
Service
Encoder: Number of services generated by the encoder module. Transcoder:
The number of transcoded services.
Input Bitrate [Mbps]
The input bit-rate to Transcoder modules. Nothing is reported for encoders.
Output Bitrate[Mbps]
Total bit-rate including PSI/SI, transmitted to the backplane. The bit-rate may
increase when a service is copied to multiple outputs.
