Three-loop temporal interpolation for error concealment of MDC

— Multiple Description Coding (MDC) can be used as an Error Resilience (ER) technique for video coding. In case of transmission errors, Error Concealment can be combined with MDC to reconstruct the lost frame, such that the propagated error to the following frames is reduced. In this paper, we propose a new temporal error concealment method named Threeloop Temporal Interpolation (TLTI). TLTI can be well combined with temporal sub-sampling ER methods, such as MDC and Alternative Motion-Compensated Prediction. In the simulation, we compare the performance of TLTI with Unidirectional Motion Compensated Temporal Interpolation (UMCTI). Both visual and quantitive results show that TLTI can achieve a better video quality than UMCTI.
