ABSTRACT:
A decoding apparatus includes a decoder configured to receive a series of encoded pictures and to decode each of the encoded pictures to produce a series of decoded pictures, each of the encoded pictures being either intra-encoded or inter-encoded, and each of the decoded pictures being either referred or, non-referred, a blocking noise suppressor configured to suppress blocking noise of each of the decoded pictures, and a controller configured to detect an amount of a load, to run each of the referred decoded pictures through the blocking noise suppressor if the detected amount of the load is no lower than a given threshold, and to have each of the non-referred decoded pictures bypass the blocking noise suppressor if the detected amount of the load is no lower than the threshold.
