| 20100027429 | Packet Switch Modeling and Using a Packet Switch Model to Test a Packet Switch - Packet switch test methods include receiving a first packet from a packet switch, receiving a second packet from processing circuitry configured to model expected behavior of the packet switch, comparing the first packet to the second packet, and, based on the comparing, determining whether the packet switch is operating according to the expected behavior. Packet switch modeling methods include identifying functionality of a packet switch to be modeled, creating, in a packet switch model, a plurality of nodes representing physical and/or logical elements of the packet switch, the nodes being configured to process packet data structures and to respectively model different portions of the functionality of the packet switch relative to one another, and, in the packet switch model, connecting the nodes with pathways by which the packet data structures may be forwarded between the nodes. | 02-04-2010 |
| 20100027536 | Processing, Forming, Modifying, and Comparing Packet Data Structures - Packet data structure formation methods include receiving a request to create a data structure for representing a packet. The request may refer to two or more fields to be included in the packet. The methods further include determining bit values and packet positions associated with the fields and, based on the determining, creating a set of bits comprising the packet. The set of bits include the bit values in the packet positions. The method further includes storing the set of bits using the data structure. | 02-04-2010 |

| 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 |
| 20100061221 | SINGLE-SIDED PRE-RECORDED DUAL-LAYER DVD DISC FUNCTIONING AS A DUAL-SIDED PRE-RECORDED DVD - An optical disc structure for playback by a read-out device is described. The optical disc structure includes a first layer with first content recorded thereon. A second layer is coupled to the first layer. The second layer has first content and second content recorded thereon. The disc of the present principles makes use of the fact that a less than full capacity DVD9 disc leaves available recording space after the end of program area and required lead-out area on the second of the two data layers of a DVD9 disc. | 03-11-2010 |
| 20100142360 | BLU-RAY DISC MADE FROM DISCARDED CD OR DVD DISCS - Briefly, in accordance with one embodiment of the present principles, a Blu-ray disc is described. The Blu-ray disc has a structure including a substrate having one of either a Compact Dics data layer and a DVD data layer along with a Blu-ray data layer. The Blu-ray discs of the present invention advantageously use Compact Discs (or DVDs) that are due to be scrapped or recycled as donor substrates for new Blu-ray discs, thereby saving polycarbonate material and eliminating the need to purchase injection molding equipment to manufacture Blu-ray discs. | 06-10-2010 |
| 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 |
| 20100322055 | OPTICAL DISC WITH PRE-RECORDED AND RECORDABLE REGIONS AND METHOD OF FORMING THE DISC - An optical disc having a region with pre-recorded data and a recordable region, a method of fabricating the disc, a stamper for forming a disc master, and a recording device for use with the disc are disclosed. Data recorded in the recordable region may be used for activation of the disc, providing unique identification or enhancing program content on the disc. | 12-23-2010 |
| 20120094054 | HYBRID DISC, METHOD AND SYSTEM OF FORMING THE DISC - A hybrid data disc, method and system of forming the disc are disclosed. The hybrid disc includes a first substrate structure bonded to a second substrate structure, and at least two data layers of different formats for access from different sides of the disc. One example provides the second substrate structure with a second substrate that has at least one curable material layer on each side of the second substrate, and the curable material has a property that results in shrinkage associated with curing of the material. Other examples provide a data disc with different stacking ring configurations, a thinner substrate and substrate structures of opposite curvature. | 04-19-2012 |
