Apparatus and method for control of blocking noise suppressor

A decoding apparatus, comprising:

• 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 one of an intraencoded picture and an inter-encoded picture, and each of the decoded pictures being one of a referred picture and a non-referred picture;
• 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 decoded pictures through the blocking noise suppressor in a case where the detected amount of the load is lower than a given threshold,
• to select more of the decoded pictures decoded from one of the inter-encoded pictures in order of being close to another one of the decoded pictures decoded from one of the intra-encoded pictures following next, as the detected amount of the load increases,
• to have the selected ones of the decoded pictures bypass the blocking noise suppressor in a case where the detected amount of the load is no lower than the threshold, and
• to transmit one of each of the decoded pictures having been run through the blocking noise suppressor and each of the decoded pictures having bypassed the blocking noise suppressor.

• having each of the decoded pictures being non-referred bypass the blocking noise suppressor in a case where the detected amount of the load is no lower than the threshold;
• and
• transmitting one of each of the decoded pictures having been run through the blocking noise suppressor and each of the decoded pictures having bypassed the blocking noise suppressor.
