Performance Evaluation of ATSC 3.0 DASH Over LTE eMBMS

Enhanced TV (enTV) features introduced into Long Term Evolution (LTE) Evolved Multimedia Broadcast/Multicast Service (eMBMS) have attracted TV broadcasters to offer their services also over eMBMS to enable service continuity and greater coverage. Considering the usual service quality offered by these content providers, an important question becomes how to deliver the offered services also over eMBMS while achieving an acceptable level of quality. In this paper, the results of an investigation that was performed for ATSC 3.0 Dynamic Adaptive Streaming over HTTP (DASH) TV broadcasting service are reported. While adequate service quality was achieved through LTE carrier aggregation (CA), additional error robustness schemes, and a flexible service configuration framework, crucial input for 5G design considerations, are derived.
