A method for receiving encoded MPEG-2 video signals and transcoding the received encoded signals to encoded H.264 reduced resolution video signals, including the following steps: decoding the encoded MPEG-2 video signals to obtain frames of uncompressed video signals and to also obtain MPEG-2 feature signals; deriving H.264 mode estimation signals from the MPEG-2 feature signals; subsampling the frames of uncompressed video signals to produce subsampled frames of video signals; and producing the encoded H.264 reduced resolution video signals using the subsampled frames of video signals and the H.264 mode estimation signals.
