A method for delivery and presentation of content-relevant information associated with frames in an AV program enables TV viewers to retrieve information on the contents (for example, objects, items, concepts and the like) associated with a frame or a set of frames (video segments) when they watch TV or video programs. The information relevant to frame(s) is delivered to a STB or DVR by third-party service providers through back channels such as the Internet if the information of how to accurately access the frames pointed by STB users are delivered to the service providers, and the content-relevant information may be presented in the form of a GUI for the TV viewer.
