Abstract: Techniques for visual presentation of video objects on a display screen include providing an overflow area around a primary or active video display area. The video objects are selectively displayed in the overflow area to provide a sense of three dimensionality or giving an appearance that the object is spilling out of the display and is present at the display. Operational modes to selectively turn on or off the use of the overflow area may be encoded in video bitstream or may be configured via a user interface.

Abstract: Methods and systems to schedule media content using a media gateway are presented. In an example method, data is collected that identifies content accessed from one or more communication networks via the media gateway by a user. Further content items for presentation to the user are determined based on the collected data. The further content items may be sourced by content channels received at the media gateway. The further content items may then be scheduled for presentation to the user. The scheduling may include defining a sequence in which the further content items are to be presented to the user.

Abstract: As presented by a server machine or a device, a graphical user interface may include first and second panels presented on a display.

Abstract: A system and method give a user control of personal data. A trusted center comprises a database for personal data, access conditions for the personal data, and a counter. A user loads personal data into the database and assigns access conditions to said data. The personal data is divided into at least two categories, each associated with a user's value. A third party requests access to personal data of a plurality of users, the request comprising search criteria. The trusted center identifies a first set of users matching the search criteria and returns the quantity of users in, and a sum of user's values for, the first set. The third party acknowledges all or part of the sum, and the trusted center returns the personal data of a second set of users for which the sum covers the user's values and updates the counters of user in the second set.

Abstract: To view media, a user may select a media stream by operating a portable device that controls a media presentation device. The portable device may be configured to multicast this stream selection to both the media presentation device and a selection analysis machine. The remote control may have or include both an infrared emitter and a cellular telephone, and the stream selection may be sent both to the media presentation device and to the selection analysis machine. The selection analysis machine may receive and store stream selections over a period of time, and these aggregated stream selections may form all or part of a profile of a user or a group of users who use the media presentation device. This profile may indicate viewing habits and choices of one or more users of the media presentation device, and the selection analysis machine may analyze this profile.

The system comprises at least one storage device, one memory module and at least one first processor, and further comprises a memory access controller module connected between the processor and the memory module, and a secure memory management module connected to the processor, the memory module, the storage device and the memory access controller.

Abstract: In example embodiments, a system and method for managing switching between devices are provided. A consolidated catalog of applications available on devices coupled to a master device is maintained. The consolidated catalog of applications is graphically presented on a screen controlled by the master device. A selection of an application from the consolidated catalog of applications is received via a control device. Based on the selected application being located at a device coupled to the master device, input is automatically switched from the master device to the device having the selected application. As a result, a display corresponding to the selected application is presented on the screen.

Abstract: A method is described for rewarding a viewer of a broadcast program in exchange for the viewer proving his presence at the time that certain program content is being broadcast. The method involves the use of running an application in a television environment, said application displaying a graphic inviting the viewer to intervene in some manner and to subsequently log the viewer's intervention, thereby documenting his viewing activity. The method further allows for the convenient and mobile reporting of the status of a log of the viewer's viewing activity. Finally, the method allows for the convenient and flexible redemption of accrued credit, as documented in the viewing log, against goods and/or services.

Abstract: The present invention concerns the field of broadcast encryptionmethod, i.e. a method to organize the distribution of keys into a group of users so that it is possible to manage the revocation of one member of the group in an efficient way. The proposed solution is a private encryption key ciphertext constant collusion-resistant broadcast encryption. The main idea behind the invention is to mix the notion of efficient tree-based key derivation (also called subset management) with individual and personalized key blinding thus achieving a full collusion-resistant broadcast encryption system. The key de-blinding is performed at the last moment thanks to a cryptographic technique called pairings (also known as bilinear maps) resulting in a global key commonly shared by all authorized (non-revoked) devices.
