A video decoding apparatus of decoding a code bit sequence obtained by encoding a block composed of MxN (M and N are natural numbers) pieces of image data, is provided. The number of pieces of data decoded by the decoding section is counted by a count section. When the count value is MxN or less and a code indicating a block boundary is detected, the decoding section starts a decoding process of the next block after ending an MxN-th decoding process. If the code indicating the block boundary is not detected when the count value is Mx(N+1) or more, the decoding section continues a decoding process. It is determined that MxN-th or earlier data among the decoded data are valid and Mx(N+1)-th or later data among the decoded data are invalid, and only the valid data is output.
