1 Digital Television Broadcasting Systems Testing in Brazil Kiev, Ukraine November 2000 Interregional Seminar on the Transition from SECAM to Digital TV Broadcasting Renato Maroja - Fundação CPqD - Campinas - SP - Brazil 1

2 Organization of the tests Entities and roles ANATEL - National Agency of Telecommunications - Brazilian regulating authority Conducts the process of defining a DTV standard for Brazil Authorized (after a public consultation) the realization of the field tests Contracted CPqD as consultant in the process Will define the DTV standard based on the tests results and other technical and non-technical aspects SET - (Brazilian) Society of Television Engineering ABERT - Brazilian Association of Radio and Television Broadcasters SET/ABERT studies the evolution of DTV standards since 1994, and has structured task groups to carry on the tests Makes planning studies to consider digital channels along with analog channels Technological agreement with Instituto Mackenzie - Human resources Instituto Mackenzie - a Brazilian private University, in São Paulo Tests methodologies Acquired test equipment, set up the laboratory and field tests installations Executed the tests and reported the results to ANATEL, together with SET/ABERT 2

3 Organization of the tests Entities and roles (cont) CPqD - Private foundation with expertise in Telecommunications support in systems aspects - CPqD works in multiple areas in telecommunications analysis and consolidation of the laboratory tests methodology development of ambiences for systems simulations analysis and consolidation of the field tests methodology checking and support in the laboratory and field tests development of tools for planning studies analysis of the tests results advice on other aspects of the introduction of Digital TV in Brazil ~1100 employees m2 3

4 Laboratory and Field Tests Tests objectives: Compare terrestrial DTV systems with respect to the transmission layer Laboratory Tests - robustness/capacity analysis of the systems under controlled conditions Interference - A to D, D to A, D to D, CW and FM: planning Robustness to impulsive noise Multipath performance static, single and multiple echoes dynamic, Doppler shift, mobility BER x C/N performance in white noise (AWGN) - modulation, planning, transmitter power 4

5 Interference: Protection Ratios D/U = Desired/Undesired Signal power ratio (db) Lower ratios more robustness Digital into Analogue (*) ATSC DVB - 2K DVB - 8K ISDB Co-channel Upper adjacent Lower adjacent Analogue into Digital ATSC DVB - 2K DVB - 8K ISDB Co-channel Upper adjacent Lower adjacent Digital into Digital ATSC DVB - 2K DVB - 8K ISDB Co-channel Upper adjacent Lower adjacent (*) CCIR 4: 37,5 db Taboo channels interference: irrelevant 5

6 Robusteness to Impulsive Noise Digital signal + gated Noise C/Neq Gate: 30s cycle, 12,5 Hz to 100 Hz, fixed T W BER < 3 x 10-6 within 2 minutes counting C/ Ne q (d B) C/Neq(dB) ,0 100,0 200,0 300,0 400,0 500,0 600,0 700,0 800,0 900,0 Window (ms) ATSC - Zenith ATSC - Chip T ATSC - Chip S ATSC - Chip A DVB 3/4 1/16 2K DVB 3/4 1/16 8K DVB 3/4 1/8 2K DVB 2/3 1/32 8K DVB - Chip N - 3/4 1/16 2K DVB - Chip N - 2/3 1/32 8K DVB - Chip M - 2/3 1/32 8K DVB - Chip L 2/3 1/32 8k DVB - Chip L 3/4 1/16 8k ISDB 3/4 1/16 4K INT4 ISDB - Chip J 6

10 Field Tests Field tests - robustness/capacity analysis under real reception conditions Coverage - real world reception includes white noise, multipath, interference from other channels and impulsive noise Gap filler - recover coverage on a shadowed spot Indoor reception - high attenuation and time varying multipath Mobility - Doppler frequency shift - some trajects in São Paulo, near the transmitter 10

11 Field Tests - TX Site São Paulo Biggest market in Brazil: 40% GNP Economical potential "Acid test": difficult coverage Topographic conditions - gap filler High density of buildings in some regions UHF channel 34 (593 Hz center frequency) TX station Site definition for TV Cultura tower: coverage, infrastructure and space for equipments and for antenna in tower Transmitter: Harris DCD20PL1, operated at 2,5 KW for all systems Antenna: 104 m agl; 9.3 dbd; 12 KW max.
