INFORMATION PROCESSING APPARATUS AND METHOD Russian patent published in 2013 - IPC H04N7/30 H04N7/68 

FIELD: information technology.

SUBSTANCE: analysis unit 621 compares image input data with image data of a previous image read from a storage unit 622. Based on the analysis result, a concealment header generating unit 623 generates a concealment header accessed by the receiver 603 during error concealment processing. Based on the concealment header, a loss analysis unit 631 performs error concealment if an error arises during transmission through suitable use of encoded data stored in the storage unit 632.

EFFECT: shorter waiting time when recovering data from packets and facilitating easy and fast processing, which can be utilised in an encoder.
