The MPEG-2 source coding algorithm is very sensitive to the channel disturbances. For instance a single bit error in the bitstream will cause a high degradation of picture quality due to the use of variable length coding. The for picture replenishment error concealment techniques may be applied at the receiver. The aim of this article is to study different error concealment techniques with different error detection methods for MPEG-2 inter coded pictures applied for terrestrial broadcasting. A Channel Model characterizing the errors of the whole terrestrial broadcasting channel is used for simulations.
