Figure 8.1: Coders View
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.
8.2 Encoder Configuration
The encoder modules have input ports that take a digital input signal, in the HD-SDI and SDI
format, and convert this signal into a compressed transport stream. One SDI input can receive
one video channel and multiple audio channels.
The encoder modules can, in addition to the main video, produce a low resolution version of the
video – PiP (picture in picture). The PiP video is multiplexed with the same audio as the main
service. The resulting PIP service is then also available to select as an output service. PCR is
embedded on the PIP video PID.
The HD-SDI encoder module with 2 channels supports both HD-SDI and SD inputs. The SDI
encoder module with 4 channels supports only SD inputs.
