Videokodierverfahren und Videokoder zur Erzeugung kodierter Videoinformation

摘要

A method for representing encoding or non-encoding of video information. In this method, an image is encoded by extending a code (COD) field which is used in H.263 and MPEG-4 to comprise at least two bits. Conveniently the two bit format indicates the cases where neither a motion vector (MV) nor a discrete cosine transform (DCT) value are encoded, where both the MV and the DCT value are encoded, and where only the MV is encoded. Therefore, in a channel with errors, the extended OCD field can be used in the error allowable mode. Also, video information can be encoded using fewer bits than in the prior art where the motion of an image is constant.
