Evaluation Quality Service of a Digital Broadcasting Station with Automatic Equipment Backup

The main task of DVB-T2 broadcasting is provided subscribers with high quality services. Quality of Service (QoS) indicator characteristics for terrestrial digital television broadcasting when the signal is distributed over the air are considered in the paper. An experiment was carried out to organize the required reservation of broadcasting equipment. DVB- T2 transmitter “Polaris TVC”, local content inserter TTV-PLPSW-0401 and universal analyzer Enensys Referee were use in experiment. The T2-MI inserter output stream file has been written when the device reserves a local stream to a national stream. There was also a record of events when the transmitter reserves the main stream as a backup. The timing diagrams are presented based on the types of errors that occurred when the inserter and transmitter were reserving input streams. The numerical values of the SAE, SDE and SIE parameters are determined for the case of the reservation of the local T2-MI stream by the tie-in device (ETSI TS 102773) and the DVB-T2 transmitter of the main stream - the reserve one. The results were evaluated by perceived quality of service (pQoS), as well as by calculating the boundaries of confidence intervals.
