Disclosed herein are systems, methods, and computer readable-media for dynamically constructing personalized contextual advertisements. The method includes extracting video metadata from a video program displayed on a playback device to a viewer, extracting component metadata from a plurality of video components stored in a media object library, extracting viewer preferences from a viewer profile, receiving synchronization information about the video program, identifying a segment of the video program susceptible to inserting a video component, based on extracted video metadata, component metadata, and viewer preferences, and transmitting the video component to the playback device and a set of instructions detailing how to insert the video component in real time in the segment of the video program. Video components can be one or more of a two-dimensional image, a video clip, a logo, a vector illustration, a three-dimensional model, a color, a character, a texture, and text. Video metadata can be extracted in real time. A viewer profile can be based on demographic information and a log of user behavior. The video program and the video component can be combined before transmitting the video component and the set of instructions to the playback device. A video component can be selected based on which advertiser offers to pay the most. The transmitted video component and set of instructions can be stored as a construction list for future use.
