Claim:
1. An encoding apparatus for encoding video data captured by a plurality of imaging units by a data unit, comprising: an encoder configured to perform inter-encoding for encoding, according to a predetermined reference relationship including (i) a reference relationship between data units each for which an image has been captured at a different image capturing time, and (ii) a reference relationship between data units each for which an image has been captured by a different imaging unit, a data unit to be encoded by referring to data units included in the predetermined reference relationship; an output processor configured to output the data unit encoded by the encoder to a decoding apparatus; a receiver configured to receive, from the decoding apparatus, error information indicating an error data unit which was not decoded by the decoding apparatus; and a controller configured to (iii) specify, based on the predetermined reference relationship, a data unit group, which has not been encoded, to which an error may propagate in a state where the error data unit indicated by the error information cannot be decoded, in a case where the error information is received by the receiver and (iv) change the inter-encoding by the encoder so that the data unit group is encoded based on a reference relationship being different from the predetermined reference relationship without referring to the error data unit and a data unit to which the error has propagated and the encoding has been performed.
