2. IVDO MULTI E+2 Overview
The iVDO®Multi E+2 is a multi channel Video Encoder that will encode four
independent video and audio channels, multiplex them along with Key-Length-Value
(KLV) metadata to generate four separate STANAG 4609 compliant MPEG2
transport streams.
It will also accept two MPEG2 transport streams from a recorder over the Ethernet
network. The unit can transport these input streams to various devices: recorders,
laptops, and the Tactical Common Data Link (TCDL) over the Ethernet network via
various means, including TCP/IP and UDP/IP.
Control of the iVDO®Multi E+2 is via a Graphic Users Interface (GUI) that can be
accessed through a WEB browser on the aircraft Ethernet network.
This manual covers both the hardware, installation, and configuration as well as the
software used to control all the encoding and multiplexing functions.

100 BaseT A networking standard that supports data transfer rates up to 100 Mbps
(100 megabits per second). 100BASE-T is based on the older Ethernet
standard. Because it is 10 times faster than Ethernet, it is often referred to
as Fast Ethernet. Officially, the 100BASE-T standard is IEEE 802.3u.
Like Ethernet, 100BASE-T is based on the CSMA/CD LAN access
method. There are several different cabling schemes that can be used with
100BASE-T, including:
 100BASE-TX: two pairs of high-quality twisted-pair wires
 100BASE-T4: four pairs of normal-quality twisted-pair wires
 100BASE-FX: fiber optic cables
1000 Base-T A networking standard that supports data transfer rates up to 1000 Mbps
(1000 megabits per second). 1000BASE-T is based on the Fast Ethernet
standard. It is referred to as Gigabit Ethernet. Officially, the 1000BASE-T
standard is IEEE 802.3z and (ratified to IEEE 802.3ab).
There are several different cabling schemes that can be used with
1000BASE-T, including:
 100BASE-X: fiber optic cables
 100BASE-CX: balanced copper cables
 100BASE-LX: long wavelength laser fiber optic cables
 100BASE-SX: near infrared (NIR) wavelength fiber optic cables
Dynamic Metadata Metadata that changes with time. Examples include aircraft position, target
position, sensor image geo-position, sensor position Static Metadata
(Metadata that does not change with time). Examples include Mission ID,
Platform Tail Number and Platform Designation.
I-Frame A complete picture that can be decoded without the need to decode any
other pictures first. It is similar to a JPEG still image.
Jerk Rate of change in acceleration
Metadata Logical
Groups
Metadata that needs to be provided as a group for the metadata to be
useable or understandable. Examples of logical groups include data that
defines aircraft position, target position, sensor image geoposition, sensor
position. Sensor image geoposition defines a region on the ground. It is
defined by a centre position and then four corners. To define the region, the
following metadata elements should be sent as a group:
Frame Center Latitude; Frame Center Longitude; Frame Center Elevation;
Offset Corner Latitude Point 1; Offset Corner Latitude Point 1;
Offset Corner Latitude Point 2; Offset Corner Latitude Point 2;
Offset Corner Latitude Point 3; Offset Corner Latitude Point 3;
Offset Corner Latitude Point 4;
Similarly target position would be defined by the following logical group of
metadata elements:
Target Location Latitude, Target Location Longitude, Target Location
Elevation; Target Error Estimate - CE90, Target Error Estimate - LE90;
Target
Location Covariance Matrix
Multicast To transmit a single message to a select group of recipients. A simple
example of Multicasting is sending an e-mail message to a mailing list.
Teleconferencing and videoconferencing also use Multicasting, but require

Word or Term Definition
more robust protocols and networks.
Standards are being developed to support Multicasting over a TCP/IP
network such as the Internet. These standards, IP Multicast and Mbone,
will allow users to easily join Multicast groups.
Note that Multicasting refers to sending a message to a select group
whereas broadcasting refers to sending a message to everyone connected to
a network.
The terms Multicast and narrowcast are often used interchangeably,
although narrowcast usually refers to the business model whereas Multicast
refers to the actual technology used to transmit the data.
N Connector A threaded Radio Frequency (RF) connector used to join coaxial cables capable
of carrying microwave frequencies
P-Frame P frames are predicted from the previous "reference" (I or P) frame in
video. If the encoder can find correlation between the previous reference
and the P frame, macroblocks in the P frame will be derived from the
reference with a motion vector and DCT difference information. In the case
where a good match cannot be found, the P frame will contain some intra
coded macroblocks.
Unicast Communication that takes place over a network between a single sender
and a single receiver.

5. Principles of Operation
5.1. Overview
The IVDO MULTI E+2 encodes video inputs from the Electro-Optics / Infra-Red
(EO/IR) System, dynamic metadata from the Interface Device (IFD) and analogue
audio from the Inter-Communications System (ICS) and produces MPEG-2 Transport
Streams (TS) compliant with STANAG 4609.
The IVDO MULTI E+2 consist of the IVDO MULTI E+2 Hardware with a Graphic
Users Interface (GUI). The primary Human Machine Interface (HMI), for both
operator and maintenance functions, is through the IVDO MULTI E+2 GUI. The
IVDO MULTI E+2 GUI can be accessed from a Windows-based Personal Computer
(PC) or laptop. This document will describe the installation and operator/maintainer
functions available through the GUI.
The GUI provides the operator with a control and reporting interface. The main
functions of the IVDO MULTI E+2 GUI are as follows:
¾Control of the audio/video and individual broadcast streams
¾Selection of metadata elements
¾Entry of static metadata
¾Configuration of the IVDO MULTI E+2 system network (IP
addresses, port information, etc.)
¾Display of the IVDO MULTI E+2 system information (software
versions, etc.)
¾Reports on current IVDO MULTI E+2 faults
¾Display of internal module information and performance data
The digital motion imagery produced by the IVDO MULTI E+2 encoder is output as
MPEG-2 Transport Streams (TS). There are four (4) main inputs used to produce the
output streams:
1. Two (2) High Definition–Serial Digital Interfaces (HD-SD1 and SD-
MPEG2 and H261.
2. Two (2) RS-170 NTSC (National Television System Committee) analog
video inputs.
The digital inputs are encoded using an H.264 compression algorithm and the analog
video inputs are encoded using a Standard Definition (SD) MPEG-2 compression
algorithm.
The IVDO MULTI E+2 can accomplish its functions of gathering video, audio and
metadata inputs; compressing or encoding those inputs; and outputting the streams to
other equipment on the AP-3C aircraft through four (4) main types of interfaces and a
Digital Signal Processor (DSP) function for encoding. The interfaces are external and
internal and they are the Ethernet interfaces, Video interfaces, Audio interfaces and
the Video Compression interface. The DSP function is responsible for the encoding
of the video, audio and metadata and then outputting a TS stream.

5.1.1. ETHERNET INTERFACES
The main processor comes with four Enhanced Triple Speed Ethernet Controller
(ETSEC) interfaces. Each ETSEC port is capable of operating at Gigabit Ethernet
(GIGE) rates.
This design uses three (3) Ethernet ports internally and one (1) externally. The
external port is via the front panel interface and is a port on the internal Ethernet
Switch.
5.1.2. VIDEO INTERFACES
These interfaces are set up to receive and send (loopback) the video signals. The
video interfaces include the four (4) Composite inputs/outputs and the four (4) S-
Video inputs/outputs used for the analog video; and the four (4) Serial Digital
Interface (SDI) inputs/outputs for digital video.
These analog video interfaces are also responsible for the Analog-to-Digital
Conversion (ADC) required before multiplexing the data and later encoding it.
5.1.3. AUDIO INTERFACES
These interfaces are set up to receive and send (loopback) the audio signals to be
multiplexed with video and metadata. There are four (4) analog audio inputs/outputs.
The audio inputs are buffered before passing through an audio compression-
decompression (CODEC) device.
5.1.4. VIDEO COMPRESSION INTERFACE
The FPGA contains a digital video multiplexer in which any video input stream may
be sent to any or all video compression devices. The selected BT.656 8 bit or Y Pb Pr
4:2:2 data is then routed to the four Video Encoders DSPs which may be configured
with any desired compression algorithm, including H.264 and MPEG 2.
The Video Encoders then compress the Video data, along with the Audio discussed in
the next section, for transport over Ethernet to the main processor for transport stream
packing. Each DSP receives UTC accurate timing from the internal NTP server
located on the main processor. Metadata packets are sent by the processor to the
appropriate DSP where the Metadata is synchronized with the associated video/audio
stream. The DSPs are equipped with 96 MB of extra memory space to support video
buffering. This equates to approximate 20 seconds of compressed HD video.
5.1.5. DSP FUNCTION
The IVDO MULTI E+2 design incorporates four DSPs each running various
customer specified video/audio algorithms. Each DSP is independent from the other
3 and therefore gives a very flexible architecture to the system design.
Communication and control come from the main Central Processing Unit (CPU) to
the DSPs via an internal Ethernet switch. The video input Field Programmable Gate
Array (FPGA) Multiplexer allows any combination of video, audio and metadata
inputs to be sent to the DSP encoding engines.
