L64781 DVB-T COFDM Demodulator Technical Manual
1-1
Chapter 1
Introduction
This chapter provides an overview of the LSI Logic L64781 DVB-T
COFDM Demodulator. It also lists this chip’s features and benets, and
provides an illustrated description of its typical performance. This chapter
contains the following sections:
1.1 Overview
The L64781 is part of a receiver for digital terrestrial television signals
transmitted in accordance with the
Digital Video Broadcasting-
Terrestrial/European Telecommunications Standards Institute
(DVB-T/ETSI) specication [1]. These signals convey digital information
using
Coded Orthogonal Frequency Division Multiplexing (COFDM), as
well as concatenated Reed-Solomon and convolutional forward error
correction (FEC) techniques. This information payload takes the form of
an MPEG-2 transport stream that conveys picture, sound, and data
information. This MPEG-2 transport stream format is used also in related
specications for the transmission of digital television signals by satellite
or cable.
The concatenated coding used in the DVB-T/ETSI specication is
identical to that in the DVB-S specication for satellite transmissions. The
L64781 chip provides a complete front-end, single-chip solution,
