Chapter 3

Electra 9200 Encoding Tutorial

This chapter describes the minimal configuration to achieve end-to-end processing of a service
containing one video and one audio stream, from SDI input to output via IP or ASI transport, on an
Electra 9200 encoder.

Workflow

All service configuration is done in the SAG Configuration page. The page represents the service
flow through the device, from left to right, input to output.

As shown in

, there are four panels in the Configuration page. The Physical Inputs shows

the inputs that are installed on the device. The Logical Inputs shows the services flowing from the
inputs. The Logical Outputs shows the encoded services that are being output. The Physical
Outputs shows the output ports and sockets that carry the output services.

Figure 3–1: The Configuration page

Configuring an Encoder with SDI Input and IP or ASI Output

In this tutorial you will see how to configure encoding for a service from SDI input. You will see
how to create and configure:

■

The input service, including an HD video stream and an audio stream.

■

The transport stream to carry the output service, including the video and audio streams, and
descriptors.

■

An IP transport to carry the output.

■

An ASI transport to carry the output.

This tutorial assumes an encoder with at least one A/V encoder card. It also assumes the encoder
platform has no configuration specified for any streams. This tutorial will not cover encoding audio
via a separate audio adapter card.
