An Introduction of the Chinese DTTB Standard and Analysis of the PN595 Working Modes

Abstract

A digital terrestrial television broadcasting (DTTB) standard named "Frame structure, channel coding and modulation for digital television terrestrial broadcasting system" was published in China in August 2006. This is the first paper of a series that provide a complete and in depth description to the standard including laboratory and field measurement results, detailed analysis on technologies in achieving stable fixed reception and fast mobile reception, as well as methodologies in spectrum allocation, and principles and technologies in performing single frequency network operation. Among the hundreds of operation modes to support multi-program SDTV/HDTV terrestrial services in the standard, the key features and major applications of a series of modes named "PN595 + C1" are described in detail. Measurement results of PN595 + C1 are also presented to demonstrate the satisfactory performances in fixed reception and high speed mobile reception
