摘要

An Internet Protocol television system includes a user profile agent, a keyword detection agent, and an information search agent. The user profile agent is in communication with a multimedia device, and generates a user profile based on information received from the multimedia device. The keyword detection agent is in communication with the user profile agent, and searches text associated with a multimedia video stream transmitted to the multimedia device for keywords associated with the user profile. The information search agent is in communication with the keyword detection agent, and connects to an information source associated with the keywords detected by the keyword detection agent, and provides additional information associated with the keywords to the multimedia device.
