5.14 Ethernet Interface GiGi (J8)
The Gigi Ethernet data interface is a 100/1000 Base T supported by an RJ45 connector. The
Ethernet interface supports two protocols, Bridge option and PRO MPEG COP3 output format.
PRO MPEG COP 3 (Code of Practice 3) is a powerful video-specific packet-based forward error
correction (FEC) algorithm, a cost-effective solution for error recovery in video streams
transported over public or private IP networks.
The Gigi Ethernet data interface can also support Bridge option, a Generic Ethernet IP Interface.
The Gigi Interface recovers IP traffic from satellite data and outputs the data to local LAN. This
feature can be enabled via the front panel by utilizing the Program Ethernet Flash menu.
5.14.1 Gigi Ethernet Data Interface, Additional Menus
When the Gigabit Ethernet Data interfaces are installed, it will add new menus for control and
status monitoring. It is recommended that all Ethernet parameters be selected prior to placing the
unit into the network.
ETHERNET INTERFACE MENU - When the Ethernet Data Interface is installed, the interface
type will reflect the Gigabit Ethernet and cannot be changed. The following items are available
under the Ethernet Interface menu
TERR FRAMING: {DVB 188}
When the Ethernet Data Interface is installed, the
terrestrial framing is fixed DVB 188 and cannot be
changed.
TERR ETHERNET:
This is where the desired MPEG over IP traffic type is
selected. The following new items are available under
the Terrestrial Ethernet menu:
TERR MAC ADDR: {0123456789AB}
This menu displays the MAC addresses of the Ethernet
Data Interface card. Entering any non-zero value in this
field will cause the EDI to use the entered value as its
MAC address. Entering a value of all zeros will cause
the Ethernet Data Interface to revert back to its original
MAC address.
