In some aspects, the disclosure is directed to methods and systems for synchronization management of high dynamic range (HDR) media metadata. A synchronization controller of a media device may receive a first set of HDR media metadata provided in connection with one or more images of media. The synchronization controller may disable a metadata synchronization indicator provided to each core of a plurality of processing cores of the media device, responsive to receiving the first set of HDR media metadata. The synchronization controller may write the first set of HDR media metadata to a first memory location while the metadata synchronization indicator is disabled. The synchronization controller may enable the metadata synchronization indicator, responsive to completion of writing of the first set of HDR media metadata to the first memory location.
