| 20090113555 | DVD Replications System and Method - A system and method for replicating protected content on media includes a controller for enabling replicating of media content from partial encoded content received at a location of the controller. A media recorder is coupled to the controller and including a modulation process ( | 04-30-2009 |
| 20090122684 | Disc Authentication by Grayscale Image in Data Area Obtained by Modulation Rule Variation (Old Title) - The present principles provide a way to place a multilevel grayscale image, visible with the bare eye in the data area of an optical disc. This feature can be used to authenticate a legitimate disc, since the image features are lost when copying a disc either with a PC recording drive or by a pirate creating a data set to be used on a laser beam recorder to produce forged ROM discs. The modulation rules are selectively varied during disc writing in a way to change the distribution of pit/land lengths, so that the at three (3) different diffraction properties are generated, and therefore produce at least three (3) distinct looks to the bare eye. | 05-14-2009 |
| 20090245055 | DVD Replication of Encoded Content - An apparatus includes a controller for enabling replicating of media content from encoded content received, and a recorder responsive to the controller for recording content on media readable by a device other than said recorder. | 10-01-2009 |
| 20090274452 | Virtual DVD on Demand and Electronic DVD Rental/Buy/Burn - An apparatus includes a storage medium for storing downloaded encoded media content, and a decoder for decoding the stored encoded media content for a choice of one of a viewing rental of the decoded media content and recording the decoded media content to a recordable media. | 11-05-2009 |
| 20100002559 | Compatible optical recording medium - The optical recording medium has a recording layer sensitive for recording at a first wavelength and sensitive for reading at a second wavelength, the recording layer having a groove structure, wherein at the first wavelength the groove structure has a diffraction efficiency into a first diffraction order sufficiently large to generate a push-pull signal, and at the second wavelength it has a diffraction efficiency into a first diffraciton order close to zero. The optical pickup for recording on an optical recording medium intended to be read with a second wavelength and a second numerical aperture is characterized in that it has a light source for generating a light beam at a first wavelength and a numerical aperture given by the second numerical aperture multiplied with a ration of the first wavelength and the second wavelength. | 01-07-2010 |
| 20100188272 | Method and apparatus for embedding second code into optical disc data by data modulation rule variation - There are provided a method and apparatus for embedding a second level code into a first level code of an optical disc by data modulation rule variation. The apparatus includes a multi-level, varying rule based modulator ( | 07-29-2010 |
