Error concealment with good restored video
quality and low computational cost is significantly
required for video streams transmitted in error-prone
channels. An efficient error concealment algorithm for
intra-frame is proposed. Circular order interpolation
method is used to prevent the accumulation of prediction
error. Meanwhile the modified inter-frame motion
compensation is used when all the adjacent blocks are
error to improve the effect of error concealment. The
experimental results show that the proposed algorithm
can restore more texture information and improve the
quality both subjectively and objectively greatly.
