Hardware Configuration
Each piece of hardware has a specific reference number. These are linked
to give a hardware configuration number (see Figure 1.3) for the whole
unit. The first part of the number refers to the enclosure and any modules
forming part of the basic unit, and each subsequent part of the number
refers to an option module. Refer to Chapter 3, Options and Upgrades for
the possible positions of each option module.
Build Revision
The build revision refers to the physical status of the enclosure and any
option modules at the time the equipment was shipped from the factory. It
is NOT the same as the Build version, which relates to software and
firmware.

Role of the Encoder in a System
1.2.1
Typical System
The Encoder is a rack mounted MPEG-2 video Encoder optimised for
multichannel systems, and also for Single Programme Transport Stream
(SPTS) equipment. It is fully MPEG-2 and DVB compliant. The Encoder has
one card, containing a single video encoder, two stereo audio encoders
(dual standard MPEG-1 (layer 2)/Dolby Digital (AC-3)
3
), composite video
decoder, CA
4
, data input and general purpose VBI extraction and encoding
circuitry.
High quality 4:2:0 or 4:2:2
5
video encoding is ensured by the inclusion of
digital noise reduction techniques
6
and many other proprietary algorithms
as well as standard MPEG compression techniques. Fully Exhaustive motion
estimation is also used.
Video can be input to the unit in serial digital component (SDI) format or
composite analogue (PAL/NTSC). There is also a logo overlay facility
allowing broadcasters to trademark material.
3
Dolby Digital (AC-3) is only available when software option M2/ESO2/AC3 is purchased.
4
CA relates to RAS and BISS. RAS and BISS are only available when software options M2/ESO2/RAS and
M2/EDCOM2/BISS are purchased. BISS is available from Build version 3.0. A E57xx Encoder may be fitted with both
RAS and BISS options but only one scrambling format can be used at any one time. BISS E is not currently supported
in Version 2.0.0.
5
4:2:2 is only available when software option M2/ESO2/422 is purchased.
6
Noise reduction is only available when software option M2/ESO2/NR is purchased.
