Abstract:
1. A method for encoding and decoding a wide-area network based remote presentation session comprising steps of: obtaining an RGB display image; converting the RGB image into a YUV 444 frame; converting the YUV444 frame into first and second YUV420 frames, wherein: spatially scaling the first YUV420 frame using spatial scaling parameters; spatially scaling the second YUV420 frame using spatial scaling parameters; encoding the first frame using a video encoder and encoding parameters; encoding the second frame using the encoding parameters; sending the encoded first and second frames to a receiver; decoding the first and second frames using a standard video decoder; combining the first and second YUV420 frames into a second YUV444 frame; and converting the second YUV444 frame into an RGB frame.
