Patent number: 7062046Abstract: A method for protecting a DVD video includes deriving a distinct version of the video data from sequential distinct data objects contained in a content database. Each data object has at least one member and selected data objects have at least two members that produce discernibly different analog output signals. In the exemplary embodiment, the members of a data object correspond to alternate “camera angles” in the DVD context. By selecting among alternate data objects available in the content database, the identity of an agent who is to be responsible for that copy is encoded in the particular copy. A modified player encodes the identity of the player into the reproduced analog video signal by making choices from among the members of the selected multi-member data objects.Type: GrantFiled: January 23, 2001Date of Patent: June 13, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Terence J.

Patent number: 6691229Abstract: A method for customizing a copyrighted digital work that is distributed in multiple data objects on, for example, a writable media, such as an optical disc, or across a global network, such as the Internet, so that an unauthorized second-generation copy can be traced to the licensee. Bits of the license-enforcement data are embedded in a licensed copy by choosing one of two previously prepared versions of each data object. These two versions both have the effect that the artist intended. The licensor can read the enforcement data more easily when digital fingerprints of the application data are carried along with the data objects. In order to remove the enforcement data with a degree of reliability, it would be necessary to introduce subtle changes in the application data and then recompute the fingerprints. This may constitute willful infringement rather than just careless copying.Type: GrantFiled: March 6, 2000Date of Patent: February 10, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Terence J. Nelson

Patent number: 5400069Abstract: Our video-conferencing system comprises stations which are remotely located from one another and interconnected by a transmission system. Each station includes a camera, a projector, and a screen, which is simultaneously translucent with respect to the projector and transparent with respect to the camera. The projector as well as the camera are placed behind and in line with the screen, thus allowing greater viewing reciprocity and eye-contact and projecting a stronger feeling of reality to the video-conferencing parties. Our screen includes segments which discriminates between projected light and light to be captured by the camera based upon polarization or angle.Type: GrantFiled: June 16, 1993Date of Patent: March 21, 1995Assignee: Bell Communications Research, Inc.Inventors: David A.

Patent number: 5117285Abstract: Apparatus to establish eye contact between communicating parties during video conferencing comprises mirrors, polarizers and a camera which are positioned with respect to one another in a special, well-defined manner such that the apparatus protrudes a minimal distance from the terminal screen. Internal to this apparatus, a first polarizer located directly in front of the terminal screen passes a polarization of the image of the distant party radiated from the terminal screen. A first mirror, which is partially silvered, reflects the image of the local party and transmits the image of the distant party that is radiated from the terminal screen and passed by the first polarizer. The reflected image of the local party is directed toward a second mirror located below the first mirror. The second mirror is positioned to capture the image of the local party from the first mirror and to reflect this image into a miniature camera.Type: GrantFiled: January 15, 1991Date of Patent: May 26, 1992Assignee: Bell Communications ResearchInventors: Terence J.

Patent number: 5083120Abstract: In a row-backlight column-shutter display, an array of sequentially illuminated leaky lightguides is utilized as the row-backlight component of the display. Light is coupled into each guide from a small high-peak-brightness source such as a light-emitting diode. Each guide is designed to leak light in a substantially uniform manner along the entire extent of a longitudinally extending edge of the guide. By combining such a row back light with an orthogonally disposed column shutter such as an array of ferroelectric liquid crystals, an advantageous flat panel display is realized.Type: GrantFiled: February 23, 1990Date of Patent: January 21, 1992Assignee: Bell Communications Research, Inc.Inventor: Terence J.

Patent number: 4357684Abstract: Transfer between paths in ion-implanted magnetic bubble memories has been achieved without the use of transfer conductors. The transfer mechanism takes advantage of the three-fold anisotropy of the implanted drive layer which makes it possible for bubbles to pass freely through gaps in one direction while being obstructed from passing through in the other direction. Transfer is controlled by a brief reversal of the direction of rotation of the in-plane field. In one embodiment, a bidirectional transfer gate is employed. Configurations using unidirectional gates and hybrid gates using conductor and reverse-rotation controlled transfer are also shown.Type: GrantFiled: November 3, 1980Date of Patent: November 2, 1982Assignee: Bell Telephone Laboratories, IncorporatedInventors: Dirk J.
