Synchronizing media content tag data

Abstract

Tag data is created from in-band data in a media content item by a remote location while the media content item is being broadcasted by a content provider and received by the remote location. The tag data identifies locations in the media content item which enables media devices to accurately jump to particular locations in the media content item based on the tag data.

What is claimed is:
