POWER SAVING SYSTEM AND POWER SAVING METHOD OF COMMUNICATION SYSTEMS BY USING DOWN STREAN AND UPSTREAM PACKET DETECTION

摘要

The present invention relates to a power saving system of a controlled device by sensing and classifying a bidirectional sound, an image, and a data packet and a power saving method. The present invention includes: a first controlled device (200) which transmits a sound, an image, and a general data packet; one or more second controlled devices (400) which receives the packets transmitted from the first controlled device (200) and transmits the packets; and a power saving unit (500) which blocks the power of a specific controlled device or all controlled devices The present invention saves power by blocking the power of an individual controlled device or all controlled devices.
