6.1 Introduction
Picture in Picture (PiP) functionality is only available in the Encoder after the purchase of the
EN8000/SWO/PIP license (please refer to Customer Services for details).
When PiP is enabled, the unit supports the simultaneous generation of a second lower-
resolution H.264 encoded video stream for use as picture in picture in a second service. There
is no audio currently associated with the PiP service.
The sequence of actions required to enable PiP operation is:
1.
Enable the video elementary streams
2.
Ensure each video stream is allocated to a separate service
3.
Source each service separately from the dual IP Network Interface Card (dIPNIC).
