<p>A system is provided for seamless synchronization through asynchronous integration of Internet content with broadcast content within a portable handheld device (14), such as a remote control or a personal digital assistant (PDA). The handheld device (14) receives program-related data from the television (12) while the user is watching a program. The program-related data places the handheld device (14) in sync with the program the user is watching and augments the user's enjoyment of the program by providing supplemental broadcast information or additional interactive features. The handheld device (14) is also configured to retrieve additional supplemental information from at least one content source distinct from the broadcast source.</p> |
