Patent ID: 7305040

Claim:
An editing apparatus, comprising: first decoding means for decoding a first encoded bit stream to generate a first base band signal; second decoding means for decoding a second encoded bit stream to generate a second base band signal; detecting means for matching phases of the first base band signal, the second base band signal, and a third base band signal, and comparing these signals to detect an edit position at which the first base band signal and the second base band signal are connected, the third base band signal being obtained by editing the first base band signal and the second base band signal; re-encoding means for re-encoding the third base band signal to generate a third encoded bit stream; and controlling means for controlling said re-encoding means to re-use first codec information used to generate the first base band signal and second codec information used to generate the second base band signal corresponding to the edit position detected by said detecting means to re-encode the third base band signal, wherein the first and second codec information includes a moving vector, a picture type, a quantizing step size, and a quantizing scale.
