Abstract :
The analysis of IP (UDP and TCP) traffic performance over terrestrial ATSC DTV channels is carried out in this work. A testbed to study the performance of a DTV datacasting system was designed and developed for this purpose. The system characterization measurements are defined to suit the performance assessment of IP data transmission over ATSC DTV channels. Different scenarios of IP data transmission subject to channel noise and traffic load are investigated. Results obtained from these tests offer valuable information for broadcasters who intend to implement IP data broadcasting services over ATSC DTV systems, such as in the planning process of data services over ATSC DTV infrastructures.
