Description
H.264/AVC provides the capability to encode highly compressed videos by exploiting spatiotemporal redundancy. High compression is needed to transmit videos over bandwidth restricted channels, but also increases its vulnerability to
transmission errors. The loss of one packet may lead to the loss of an entire frame, and subsequently degrading the quality of the following frames. We propose an error concealment algorithm for H.264/AVC that will estimate the lost frame based on motion information from the previous frames. We give importance to the frames close to the lost frame, but also consider the motion of
other previous frames. The results show some improvement over conventional methods of concealing frame losses such as frame copy and motion copy methods.
