On Services Unequal Error Protecting and Pushing by Using Terrestrial Broadcasting Network

This paper proposes a novel services unequal error protecting (UEP) and pushing scheme by using terrestrial broadcasting network (TBN). Experiments show that the most important services (MIS) contributing to the most part of quality of experience (QoE) are only a small size of all services. Based on this fact, we duplicate several copies of the MIS firstly in the proposed scheme; then, only one copy of MIS is encoded together with the rest less important services (LIS) by LT code; the others uncoded copies are pushed with the encoded data by the TBN. Simulations show that the proposed scheme can effectively improve the QoE score of users.
