A method for receiving encoded H.264 video signals and transcoding the received encoded signals to encoded MPEG-2 video signals, including the following steps: decoding the encoded H.264 video signals to obtain uncompressed video signals and to also obtain H.264 feature signals; deriving MPEG-2 feature signals from the H.264 feature signals; and producing the encoded MPEG-2 video signals using the uncompressed video signals and the MPEG-2 feature signals. The H.264 feature signals include H.264 macro block modes and include H.264 motion vectors.
