Latest Patents
One of Liu's latest patents focuses on suppressing pixel coloration errors in HDR video systems. This innovation aims to limit pixel coloration errors that can occur during the signal processing of HDR video signals. By converting visual content to a half precision floating point representation, small amounts of signal noise can be introduced. Liu's process detects these noise amounts in pixel color component values and suppresses them to prevent accumulation during HDR signal processing, thereby enhancing image quality.
Another significant patent involves decrypting and decoding media assets through a secure data path. This invention describes a client device that includes both a host core and global memory in a common execution environment, as well as a secure core and restricted memory in a secure execution environment. The secure core generates a license challenge and processes a license challenge response that includes a media content decryption key, ensuring that the decryption key and decrypted media asset remain protected from unauthorized access.
