Electronic devices in a local area network (LAN), e.g., a DVD video recorder, plasma display, and audio controller in a home network, are protected by a security system that is networked with the devices. In one aspect, the security system periodically polls the devices to confirm that they are present in the LAN. If a device does not respond, an alarm is set. Installation of the electronic device in an unauthorized network is detected by verifying the Internet Protocol (IP) address of the device, such as when the device attempts to contact a server that provides services such as downloading new or updated software to the device, performing remote programming, and uploading diagnostic data. The devices may encrypt their messages using encryption codes that are unique individually or for a specified group of electronic devices.

A limited-use Digital Versatile Disc (DVD) includes a storage layer for storing content data and control key data. At least one mark of photosensitive dye is disposed on the disc exterior to the storage layer and over at least a portion of the control key data. In one embodiment, the mark is initially transparent to allow a DVD player to read the control key data. The mark changes from clear to become opaque when it is exposed to DVD reader laser light for a cumulative period of time. This change in the optical property of the mark and the configuration of the control key data prevents further reading of the content data after predetermined reading and playback usage of at least some of the content data is permitted. In another embodiment, the mark is initially opaque to initially prevent the successful reading of the control key data, and permanently changes to transparent when exposed to DVD reader laser light for a cumulative period of time.

A method of making a Web-DVD which integrates computer-based content, such as Web links / HTML content or images, with DVD-Video content by using a graphical user interface (GUI) is disclosed. The method provides a software application that allows a developer to add highly integrated computer-based content, such as, but not limited to, HTML content such as Web site links and images, PDF files and / or Power Point files, to a predetermined DVD-Video content with the developer using the GUI to create a Web-DVD instead of using complex JavaScript or HTML commands or programming language. The software application writes a series of DVD-ROM files, based on the developer's selection, e.g., “point and click,” of the GUI options, that create an interaction between the DVD-Video content and the computer-based content or HTML content.

The present invention relates to improvements in the generation of an authoring file, readable by an authoring program of a DVD-Video or other interaction video media, that defines the playback structure of the content residing in a given disc's "authored content zone" and also defines the location of the assets that make up the disc's "presentation data." The improvements allow generation of an authoring file that references assets that are within the authored content zone of the medium. This allows the authoring "project" from which the final DVD-Video disc image was created to be reopened in a compatible authoring program-and to be modified by such a program-without reference to any of the original source materials.

A method and system for segmenting video into an optimal set of video clusters that correspond loosely to one or more events, date ranges, time ranges, chapters or other logical segmentations of the digital video that is meaningful to the user. Video shots are selected from one or more video files on a computer-readable medium. The video shots are arranged in chronological order and a distance (e.g., time gap) between each successive pair of the arranged video shots is determined.
