20100127013 | DVD KIOSKS - Distribution devices for creating and dispensing digital content to a user are described. The distribution devices (i.e., a kiosk) contain an apparatus for manufacturing and dispensing a desired medium (i.e., DVD) for any desired type of digital content or media (i.e., a movie or a song) on demand by a user. The distribution devices can be connected to any electronic communications network that allows that media to be downloaded to a specific distribution device, if needed. Thus, a user can select the media (i.e., a desired movie) that may not be currently available at that specific distribution device. That media can then be downloaded from the electronic communications network, the medium containing the media created, and then the medium dispensed to the customer. Thus, the customer's selection of any desired media can be increased and costs for operating the distribution devices can be reduced. Other embodiments are described. | 05-27-2010 |
20100169652 | DIGITAL WATERMARKING SYSTEMS AND METHODS - Systems and methods for protecting digital content using digital watermarks and for distributing that protected digital content are described. The digital watermark contains watermark information, fingerprint information, and any other information desired by the provider of the digital content. To insert the digital watermark in the digital content, a section of the digital content is selected, whether it is a random section or a desired section (such as the first or last section), and then that section is broken into a given number of individual slides. The digital watermark is created as an additional slide or frame and then placed between the slides of that section. These individual slides, which now contain the watermark, are re-combined and then re-attached to the remainder of the digital content when desired, such as on the fly or at the time of the user's purchase of the digital content. The user (or other viewer) receives only a single packet of information for the digital content, rather than numerous packets of information, preventing compression and decompression processes from avoiding the watermark since any such compression would not only diminish the slide with the watermark on it, but also the content and render the digital content unusable. Other embodiments are described. | 07-01-2010 |
