Classification: CPC H | IPC H

Claim 17:
18. A video processing apparatus, comprising:
a processor executing instructions stored in a memory to:
obtain a video bitstream or a video file, wherein the video bitstream or the video file carries perception attribute information of at least one object and spatial location information of the at least one object, the perception attribute information indicates a human body perception attribute of the at least one object and is used to indicate a property presented when the at least one object is perceived by a human user, the spatial location information is used to indicate a spatial location of the at least one object, the video bitstream is generated after source video data is encoded, and the video file is used to describe a video attribute of the source video data;
obtain perception attribute information of at least one target object and spatial location information of the at least one target object in the video bitstream or the video file, wherein the at least one object comprises the at least one target object; and
perform perception rendering on a perception attribute of the at least one target object based on behavior of the human user, the perception attribute information of the at least one target object and the spatial location information of the at least one target object;
wherein the processor executing the instructions stored in the memory to perform the perception rendering on the perception attribute of the at least one target object comprises the processor executing the instructions stored in the memory to:
determine a scent strength value of a first target object in the at least one target object at a current location of the human user based on the current location of the human user, spatial location information of the first target object, and a maximum scent strength of the first target object, and
emit a scent corresponding to the scent strength value and a scent code of the first target object; or
determine a touch strength value of a second target object in the at least one target object at a touch point of the human user based on a current location of the touch point of the human user, spatial location information of the second target object, and a maximum tactility strength of the second target object, and
feed back tactility perception corresponding to the touch strength value and a tactility code of the second target object to the human user.
