Patent number: 7292692Abstract: An encryption arrangement for television programs or other digital programming consistent with certain embodiments sends content completely in-the-clear and also encrypts only a portion of the content required for full presentation of a television program. The arrangement allows interoperability between new TVs that can handle encryption and older TVs that cannot. Regulations prevent new TVs from receiving only the clear content. New TVs are made to descramble the encrypted portions of the content. Older legacy TVs can receive all the content in the clear. The encrypted portions are chosen so that dramatically less bandwidth is required as compared to full dual carriage of the content. Licensing provisions relating to the encryption technology can be used to control unauthorized use of content. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.Type: GrantFiled: January 29, 2004Date of Patent: November 6, 2007Assignees: Sony Corporation, Sony Electronics Inc.Inventors: James Bonan, Brant L.

Patent number: 7218738Abstract: A selective encryption encoder has a packet identifier that identifies packets of a specified packet type forming a part of a program. A packet duplicator duplicates the identified packets to produce first and second sets of the identified packets. A PMT (program map table) inserter generates temporary identifying information that identifies the first and second sets of identified packets inserts the temporary identifying information as user private data in a program map table (PMT) forming a part of the transport program specific information (PSI). The data are then sent to and received from a primary encryption encoder to encrypt the first set of identified packets under a first encryption method. A secondary encrypter encrypts the second set of identified packets under a second encryption method. The PSI is then modified at a PSI modifier to remove the temporary identifying information and to correctly associate the first and second sets of identified packets and the unencrypted packets with the program.Type: GrantFiled: October 18, 2002Date of Patent: May 15, 2007Assignees: Sony Corporation, Sony Electronics Inc.Inventors: Leo M.

Patent number: 7155036Abstract: A feature based face recognition method and apparatus. Global amplitude and direction is calculated for regions defined by a sliding window over an input gray scale image. These values are low pass filtered and a search is carried out for candidates for an eye. Once an eye candidate is identified by comparing the amplitude with a threshold, the other eye is presumed to be located a fixed distance away at the angle of the eye. The mouth is then determined to be in a predetermined location perpendicular to the angle of the eyes. A face contour is estimated by defining two ellipses between which face contours having angles similar to the ellipse are found. Multiple detections are possible and those detections are merged by averaging. The image is resized and the process repeats until the image has been reduced to its minimum size.Type: GrantFiled: February 21, 2001Date of Patent: December 26, 2006Assignees: Sony Corporation, Sony Electronics Inc.Inventor: Pingshan Li

Patent number: 7151833Abstract: Certain embodiments consistent with the present invention involve a method of selectively encrypting and decoding digital video content. Certain of the packets are selected for encryption according to a selection criterion, wherein the selected packets exclude packets containing start of frame (SOF) headers. The selected packets are encrypted while retaining the packets containing the SOF headers unencrypted to form selectively encrypted digital video content. In decoding selectively encrypted digital video content, offsets are calculated for at least one of I frames and P frames from the SOF headers and the calculated offsets are stored as an offset table. The offset table can then be accessed to enable trick play of the selectively encrypted digital video content.Type: GrantFiled: March 19, 2003Date of Patent: December 19, 2006Assignees: Sony Corporation, Sony Electronics Inc.Inventors: Brant L.
