Techniques for using video source context information in post-processing operations

Systems, apparatuses, and methods may provide source device techniques that identify a plurality of object regions in a video frame, automatically generate contextual information for the video frame on an object-region-by-object basis, and embed the contextual information in a signal that includes the video frame. Further, the playback device technique may decode a signal containing the video frame and the embedded contextual information, identify a plurality of object regions in the video frame based on the embedded contextual information, and automatically select one or more post-processing configurations for the video frame on an object region-by-object basis. 系统、装置和方法可提供源设备技术，该源设备技术标识视频帧中的多个对象区域，逐对象区域地自动生成视频帧的上下文信息，并将上下文信息嵌入包含视频帧的信号中。此外，回放设备技术可以对包含视频帧和所嵌入的上下文信息的信号进行解码，基于所嵌入的上下文信息标识视频帧中的多个对象区域，并逐对象区域地自动选择用于视频帧的一个或多个后处理配置。
