Introduction
This chapter provides an overview of the LSI Logic L64780 DVB-T
COFDM Demodulator. It also lists this chip’s features and benefits, and
provides an illustrated description of its typical performance. This chapter
contains the following sections:
The L64780 is part of a digital terrestrial television receiver for signals
transmitted in accordance with the Digital Video Broadcasting-
Terrestrial/European Telecommunications Standards Institute
(DVB-T/ETSI) specification. 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
specifications for the transmission of digital television signals by satellite
or cable.
