Abstract:
There is provided a lossless video compression method for an H.264 codec. A lossless video compression method for an H.264 codec according to an aspect of the invention may include: dividing an image to be compressed into n (n is a natural number) pixel regions; compressing the n pixel regions to convert the n pixel regions into n variable length compression codes; and generating an address for writing or reading the n variable length compression codes by patterning a size variation of the n variable length compression codes, thereby achieving lossless compression of data to be written in an external memory and allowing for access to data at an arbitrary location.
Abstract:
A training apparatus based on motion content includes a plurality of motion detecting sensors dispersedly arranged in a body of a user to obtain position information signals of respective body parts of the user, a motion controller analyzing the position information signals to detect a user motion, and comparing the detected motion with a reference motion provided from motion contents to generate a motion calibration signal for training of a motion calibration, and a plurality of motion calibrating sensors dispersedly arranged in the body to stimulate the body part of the user according to the motion calibration signal and calibrate the user motion, and consequently can provide a training service for continual motions and increase a motion calibration effect.
