A method and apparatus is provided for connecting a computer to electronic addresses in sync with an audio/video broadcast. Simultaneously with the broadcasting of audio/video programming, an address transmitter transmits an address, such as a URL, identifying an on-line service which contains information about the audio or video programming. This address is received by a computer and used to automatically access the on-line service. Preferably, the process is repeated with different addresses corresponding with different programming. It is also preferred that the addresses be sent via a paging system.

This paper presents a video watermarking technology for broadcast monitoring. The technology has been developed at the Philips Research Laboratories in Eindhoven in the context of the European ESPRIT project VIVA (Visual Identity Verification Auditor). The aim of the VIVA project is to investigate and demonstrate a professional broadcast surveillance system. The key technology in the VIVA project is a new video watermarking technique by the name of JAWS (Just Another Watermarking System). The JAWS system has been developed such that the embedded watermarks (1) are invisible, (2) are robust with respect to all common processing steps in the broadcast transmission chain, (3) have a very low probability of false alarms, (4) have a large payload at high rate, and (5) allow for a low complexity and a real-time detection. In this paper we present the basic ingredients of the JAWS technology. We also briefly discuss the performance of JAWS with respect to the requirements of broadcast monitoring.

Video watermarking system for broadcast monitoring

Users are able to subscribe to notifications regarding activity around particular documents (e.g., changes to and/or annotations to the documents). A variety of different notification parameters can be set by the user, allowing him or her to request the type(s) of notifications he or she would like to receive, as well as how frequently notifications are to be received.

Notification of activity around documents

A plurality of user-selected annotations are used to define a playlist of media segments corresponding to the annotations. The user-selected annotations and their corresponding media segments are then provided to the user in a seamless manner. A user interface allows the user to alter the playlist and the order of annotations in the playlist. The user interface identifies each annotation by a short subject line.

Interactive playlist generation using annotations

An enhanced broadcasting system for presenting audio or video broadcoasts and related enhancements, the system comprising: a receiver for receiving an audio and video broadcast signal; a first display unit, connected to the receiver, for displaying content of the audio and video broadcast signal; a computer configured for receiving a code fragment correlated to the content of the audio and video broadcast signal; the computer executing software for interpreting the code fragment and correlating the code fragment to the audio and the video broadcast signal with respect to time; and a second display unit, connected to the computer, for displaying the interpreted code fragment.
