Publication number: 20100226425Abstract: An encoding data processor generates a video material item marked copy by representing a payload data word as a code word and embedding the code word into a copy of the video material item. A preprocessor divides the payload word into plural parts, forms plural initial values from the plural parts, each initial value formed by adding parts of the payload data word to each initial value successively starting with the first part added to the first initial value, and adds the first and second to the second initial value so each subsequent initial value includes all parts of the payload data word of the previous initial values and a new part of the payload data word. An encryption processor receives each initial value and generates an encrypted data stream using a payload encryption key. A combiner combines the encrypted payload data word with the video material item.Type: ApplicationFiled: May 3, 2007Publication date: September 9, 2010Applicant: SONY UNITED KINGDOM LIMITEDInventors: Stephen Mark Keating, Ian McLean, Mark Julian Russell, Daniel Luke Hooper, Daniel Warren Tapson

Patent number: 7792322Abstract: An encoding data processing apparatus is arranged to generate a marked copy of an image by introducing a code word into a copy of the image. The apparatus comprises a code word generator operable to generate the code word. The encoding apparatus includes an image perception analyser and a strength adapter. The image perception analyser is operable to receive the image and to generate weighting factors. A combiner is operable to combine the weighted code word with the image. The image perception analyser includes a contrast masking engine, a smoothness compensation engine and a compensation combiner. The weighting factor has an effect of reducing the code word coefficients for image parts having lower relative contrast measures. A compensation combiner is operable to combine the compensation factors with the weighting factor. The likelihood of a code word being perceivable when the code word is combined with an image is reduced.Type: GrantFiled: October 28, 2005Date of Patent: September 7, 2010Assignee: Sony United Kingdom LimitedInventor: Daniel Warren Tapson
