— The evaluation of IP (UDP and TCP) data transmission throughput performance over terrestrial ATSC DTV channels was carried out in this work. A testbed to study the IP data transmission performance was developed for this purpose. Issues limiting the throughput of IP data transmission over DTV channels were analyzed. Throughput affected by channel noise and traffic load was investigated under various IP data transmission scenarios. Results obtained from these tests offer valuable information for broadcasters who plan to implement datacasting services over ATSC DTV systems.
