Display stream compression pixel format extensions using subpixel packing

A device for packing pixel values arranged in an O-channel format for encoding by an M-channel codec, comprising:

• a transceiver circuit comprising 0 input channels configured to respectively receive O input subpixel values of an input pixel value arranged in the O-channel format;
• at least one buffer configured to buffer the O input subpixels;
• and
• a logic circuit configured to rearrange the O input subpixels into a set of output pixel values, each output pixel value comprising M output subpixel values arranged in an M-channel format, O having a greater value than M, wherein at least a portion of the rearranged M output subpixels maintain their relative spatial positioning from prior to being rearranged from the O input subpixel values;
• wherein the transceiver circuit further comprises M output channels configured to output the set of output pixel values to the M-channel codec.

A method of unpacking pixel values arranged in an M-channel format, comprising:

• receiving a set of input pixel values from an M-channel codec, each input pixel comprising M input subpixel arranged in the M-channel format;
• rearranging each of the input subpixel values into a set of output pixel values, each set of output pixel values comprising O output subpixel values arranged in an O-channel format, O having a greater value than M, wherein at least a portion of the rearranged O output subpixels maintain their relative spatial positioning from prior to being rearranged from the M input subpixel values;
• and
• providing the output pixel values as an output.
