Abstract:
1. A method of generating a video packet, the method comprising: generating at least one pixel block comprising at least one reference pixel and at least one neighboring pixel adjacent to the at least one reference pixel from among a plurality of pixels of a video frame; replacing a pixel value of the at least one neighboring pixel in the at least one pixel block with a pixel difference value, which is a difference value between a pixel value of a pixel adjacent to the at least one neighboring pixel and the pixel value of the at least one neighboring pixel; and generating a plurality of packets so that a pixel value of the at least one reference pixel and the pixel difference value of the at least one neighboring pixel are allocated to different packets among the plurality of packets according to positions of the at least one reference pixel and the at least one neighboring pixel within the at least one pixel block.
