3.7.21 How to Copy and Move Transport Streams and Services
To copy or move a previously created Transport Stream or service, or an existing
component from one output to the other, proceed as follows:
1. Select the Transport Stream, service or component.
Note: More items can be highlighted by holding down the Ctrl or Shift key while
clicking.
2. To move the selected items, drag them over another valid dropping location and
release the mouse button. For Transport Streams, valid dropping positions are
the outputs, for services, the Transport Streams and for components, the
services.
3. To copy the item instead of moving, hold the Ctrl key while dragging. The item is
moved or copied to the specified location.
The commands in the Edit menu of the Properties widget can also be used for
copying or moving items. To use these, proceed as follows:
1. Highlight the item or items you want to copy or move, and then choose Edit >
Copy or Edit > Cut.
2. Then, highlight the location where you want to paste the items. Select Paste
from the Edit menu. The items will be copied or moved to the new location.
3. There is also an option to create an identical mirror of an existing Transport
Stream such that any changes made to the original Transport Stream are
automatically applied to the mirrored Transport Stream. To create a mirrored
Transport Stream highlight the Transport Stream to be copied, chose Edit >
Copy, highlight the output where the mirrored TS is to be applied to and chose
Edit > Paste as Mirror
4. To save your changes, click the Apply All button located at the right side of the
user interface below the page tabs.
Note: A component can be included in more than one Transport Stream as an
instance of an input component. Therefore, any change to it, be it automatic
by the bit rate tracking algorithm or manually applied by the user, is
reflected in all instances.
3.7.22 How to Configure MGP
3.7.22.1 Overview of MGP
The Multicast Guard Protocol (MGP) is a mechanism used to control the emission of
multicasts containing media streams over IP, where multiple AVP units can emit the
same multicast onto the same network. This mechanism ensures only one AVP unit
in such a group will emit. In a system deployment, this permits controlling software
to not have to configure downstream switches to prevent duplication of the same
multicast onto the same network.
