Patent ID: 8364019

Claim:
A video decoding device comprising: a decoder configured to decode a plurality of separate partial areas of each of pictures included in encoded video data and a motion vector indicating a positional relationship between each of the partial areas and a partial area of a different picture referenced in order to encode the partial area; an error detector configured to detect, as an error area, a partial area that is unable to be decoded by the decoder from among the plurality of partial areas; a referenced area determiner configured to, when the error area is included in a first picture, determine, using the motion vector of a partial area included in a second picture that is subsequent to the first picture in the order in which the pictures are decoded, a referenced area of a third picture that has already been decoded, the referenced area corresponding to the error area; a concealment unit configured to conceal the error area using data included in the referenced area; and an image integrator configured to reproduce the first picture by arranging the concealed error area and the decoded partial areas included in the first picture in a predetermined order.
