the High Efficiency Video Coding (HEVC) standard has the
counter-effect of decreasing error resilience in transmission over
error-prone channels. To increase the error resilience of HEVC
streams, this paper proposes a checkerboard reference picture
selection method in order to reduce the prediction mismatch at
the decoder in case of frame losses. The proposed approach not
only allows to reduce the error propagation at the decoder, but
also enhances the quality of reconstructed frames by selectively
constraining the choice of reference pictures used for temporal
prediction. The underlying approach is to increase the amount of
accurate temporal information at the decoder when transmission
errors occur, to improve the video quality by using an efficient
combination of diverse motion fields. The proposed method
compensates for the small loss of coding efficiency at frame loss
rates as low as 3%. For a single frame-loss event the proposed
method can achieve up to 2 dB of gain in the affected frames
and an average quality gain of 0:84 dB for different error prone
conditions.
