4.1 Overview
The Thales Broadcast & Multimedia Affinity® is an advanced low power solid-state Coded
Orthogonal Frequency Division Multiplexing (COFDM) Digital Video Broadcast-Terrestrial (DVB-
T/DVB-H) transmitter. The Affinity® is fully compliant with European Telecommunications
Standards Institute (ETSI) EN 300744 DVB-T, EN 302304 DVB-H specification requirements,
and complies with all FCC requirements. The design goal of the Affinity® family of transmitters
was to allow broadcasters to cost effectively begin broadcasting in DVB-T/DVB-H formats while
accomplishing the following objectives:

Ease of monitoring and diagnostics
Flexible solutions for all site layouts and installations
The Affinity® L-Band solid-state low power transmitter is available in several models providing
output powers ranging from 50 to 400 Watts average (rms). The transmitter brand can house up
to sixteen high-gain full-band GaAs FET amplifier modules operating in parallel. The quantity of
amplifiers installed for a system is determined by the desired output power.
Each Affinity® transmitter is provided with a DVB-H RF Sirius Exciter containing linearization
circuits to compensate for both linear and non-linear distortions. The correction can be operated
in an adaptive mode allowing automatic compensation and signal optimization.
The Affinity® family of solid-state low power transmitters includes an advanced control system
providing enhanced monitoring and diagnostic capability. The single or dual drive configuration
determines the operating interface for the system.
For single drive (SD) configurations, the front panel of the DVB-H RF Sirius Exciter includes a
Local Control & Monitoring Panel (LCMP) with a man-machine interface (MMI). The MMI
consists of a front panel Liquid Crystal Display (LCD) and a soft-key activated menu that
provides transmitter controls, power readings and alarm indicators.
For dual drive (DD) operation, each of the DVB-H RF Sirius Exciter units are controlled by an
external Central Processing Unit (CPU) that includes switchover management for a Web server
or SNMP agent. The LCMP for dual drive operation consists of a color touch screen with menus
and bar graph.
Remote operation for both configurations can be made by either an embedded Web server
through a standard browser, or through a SNMP agent by means of an SNMP manager.
