Method and apparatus for generating video packet

A method of generating a video packet, the method comprising:

• generating at least one pixel block comprising of 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 bits respectively indicating 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 a level of the bits.

A method of generating a video packet, the method comprising:

• generating a first pixel block comprising a first reference pixel and at least one first neighboring pixel;
• replacing a pixel value of each of the at least one first neighboring pixel with a first pixel difference value, wherein each first pixel difference value is calculated by selecting a first neighboring pixel from among the at least one first neighboring pixel, selecting a first pixel adjacent to the selected first neighboring pixel, and calculating a difference value between a pixel value of the first pixel adjacent to the selected first neighboring pixel and a pixel value of the selected first neighboring pixel;
• and
• generating a plurality of packets such that a different packet among the plurality of packets is generated for each pixel in the pixel block.
