Workflow Management
Electra VS Convergent Video System offers the possibility to create as
many templates as you need. Such templates are called workflows. A
workflow describes the different processes that will be applied to the
video streams.
The provided flexibility allows the operator to build any kind of encoding
process:
 Encoding for traditional networks (IPTV, Cable, DTH and DTTV)
 Encoding for WebTV (multi-screens)
In addition to the standard encoding capability, Electra VS Convergent
Video System allows
 Logo addition in the video

Text addition in the video
 Black Out Management
 Automatic Loudness Control on audio
 Content Protection

Internal statistical multiplexing
 Etc.
The following figure shows a simple IPTV workflow.
Figure 3-2. Simple IPTV workflow
Workflows are made of processing components (e.g. TS over IP input,
MPEG-4 decoding,...) which make up an audio/video processing chain
when they are linked together.
Each processing component has its own parameters (e.g. IP@destination
and UDP destination port parameters for the TS over IP input processing
component). These parameters can receive default values and can be
defined to be visible/hidden and editable/not editable when an
audio/video process is launched (job) based on the workflow.
