Dynamic coefficient reordering

An apparatus for compressing video data, the apparatus, comprising:

• a memory;
• and
• a processor configured to execute instructions stored in the memory to:
• transform an array of pixels of a block of a frame of the video data into coefficients;
• create a default transmission order of the coefficients of the block;
• create an optimal transmission order of the coefficients of the block;
• compare a coefficient position of a coefficient from the coefficients in the optimal transmission order with a coefficient position of the coefficient in the default transmission order;
• determine an update value based on the comparison, the update value indicative of whether the coefficient position of the coefficient in the optimal transmission order is the same as the coefficient position of the coefficient in the default transmission order;
• and
• selectively encode position information of the coefficient in the optimal transmission order based on the update value,
• wherein the position information is at least one of the coefficient position or band information, the band information indicating a position of a group of coefficients.
