1. A computer-implemented method, comprising: dividing a video file into video frames; identifying video features associated with a plurality of objects included in the divided video frames, wherein the video features identify a logo, a trademark, a structure, a shape, a view, and a color associated with the plurality of objects; based on the identified video features, identifying a target object associated with the plurality of objects in the video frames, wherein identifying the target object comprises determining at least one set of similar objects based on video features, the set of similar objects being identified as a candidate object, and in response to the candidate object appearing in a predetermined plurality of successive video frames, identifying the candidate object as the target object; comparing the target object to information associated with a set objects stored on a data source to identify the information to associate with the target object; generating and transmitting to at least one terminal device an ultrasonic signal containing the identified information related to the target object; associating the ultrasonic signal containing the identified information with the video file, wherein associating the ultrasonic signal with the video file comprises associating the ultrasonic signal with a plurality of video frames of the video file in which the target object appears; and transmitting the ultrasonic signal for the target object at a time interval from a first one of the predetermined plurality of successive video frames in which the target object appears to a last one of the predetermined plurality of successive video frames.
