Abstract:
1. A method of encoding video utilizing inter-color-plane prediction comprising: writing a parameter into a header of a compressed video bitstream indicating color plane format; selecting one out of a plurality of predetermined rescaling schemes based on said color plane format; encoding a first block of original samples of a first color plane into said compressed video bitstream; reconstructing a block of reconstructed samples of said first color plane corresponding to said first block of original samples; performing an inter-color-plane prediction process using said selected rescaling scheme and said block of reconstructed samples of said first color plane to produce a block of prediction samples of a second color plane; subtracting said block of prediction samples of said second color plane from a second block of original samples of said second color plane to produce a block of residual samples of said second color plane, whereas the positions of said first block and said second block of original samples are aligned; encoding said block of residual samples of said second color plane into said compressed video bitstream.
