An encoder and method for using the same to encode a video stream is disclosed. The encoder includes an input port that receives a video stream that includes a plurality of frames. A first compression sub-system generates a plurality of compressed reference frames using a lossy compression method. The compressed reference frames are communicated to a remote device. A reference frame storage sub-system stores one of the compressed reference frames in a compressed format for use in compressing a subsequent frame in the video stream using a lossy compression method. A second compression sub-system encodes a second plurality of frames using the compressed reference frame stored in the reference frame storage sub-system as a reference, the second compression sub-system generating a compressed video frame. Each compressed video frame that is not a reference frame is coded directly from one of the reference frames. |
