Information processing device, method and program

An information processing method in an information processing device comprising the steps of:

• causing an obtaining means of the information processing device to obtain encoded data obtained by encoding image data which is formed by blocks with predetermined data unit, for each block, and redundant data for the encoded data, which is obtained by encoding the encoded data using a forward error correction method;
• causing a decoding means of the information processing device to decode each block using the encoded data and intermediate data generated during a decoding process for a block which has been decoded if the encoded data to be included in the block and obtained by the obtaining means is all collected, and to decode each block using dummy data used instead of the lost encoded data, the encoded data, and intermediate data generated during a decoding process for a block which has been decoded if the encoded data to be included in the block and obtained by the obtaining means is not all collected;

• and
• causing a setting means of the information processing device to decode the recovered encoded data and set intermediate data obtained during the decoding to be used to decode a subsequent block as intermediate data during a decoding process for a block which has been decoded.
