Patent ID: 7920634

Claim:
An editing apparatus, comprising: first decoding means for decoding a first encoded bit stream to generate a first base band signal; first acquiring means for acquiring a first codec information used to generate the first base band signal; second decoding means for decoding a second encoded bit stream to generate a second base band signal; second acquiring means for acquiring a second codec information used to generate the second base band signal; edit point detecting means for detecting an edit point in a third base band signal, by comparing pixels of the first and second base band signals with pixels of the third base band signal on a picture basis to determine whether the third base band signal matches the first or second base band signal, wherein the third base band signal is obtained by connecting the first and second base band signals at the edit point; selecting means for selecting which of the first and second codec information is used for re-encoding the third base band signal according to the detected edit point; 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 the codec information selected by the selecting means to re-encode the third base band signal.
