METHOD AND APPARATUS FOR PROTECTING AGAINST COPYING CONTENTS BY USING WIHD DEVICE

摘要

A method and apparatus for protecting against copying high definition (HD) contents transmitted in a wireless HD (WiHD) network by using a WiHD source or sink device, the method including: determining a type of copy protection of contents transmitted in the WiHD network; calculating accumulatively a number of media access control (MAC) sub-packets as a input counter information, wherein the MAC sub-packets constitute a MAC payload including the contents; packetizing the type of copy protection and the input counter information into a MAC packet; and transmitting the MAC packet to a WiHD sink device.
