Abstract
A method, apparatus and a computer readable medium for skipping macro blocks of a compressed video. The method includes, for at least one INTER frame, saving a set of macro blocks including at least one of a macro block having a motion vector greater than a predetermined motion vector threshold, a macro block having positional correspondence to at least one macro block having a motion vector, a macro block having a size greater than a predetermined macro block size threshold, and a macro block having positional correspondence to a second macro block in a previous group of pictures, the second macro block having a motion vector. The method deletes and marks as skipped one or more remaining macro blocks, and merges the set in an order to create a compressed frame including a skipped macro block. The processor implements the method, and the computer readable medium contains processor instructions.
