| 20100332819 | DIGITAL CONTENT ACCESS CONTROL - Control of access to at least one digital content is managed as a function of at least one access criterion. The digital content is transmitted to at least one terminal in the form a data stream. The access criterion is stored in the terminal as a function of an identifier. The terminal receives the data stream in association with a control message indicating the identifier. It then retrieves the stored access criterion as a function of the identifier received in the control message. Finally, it verifies whether the stored access criterion is satisfied in order, where appropriate, to authorize access to the content. | 12-30-2010 |

| 20090076984 | DISTRIBUTING REAUTHORIZATION TIME IN THE EVENT OF TARIFF TIME CHANGE - Embodiments of the present invention provide techniques for distributing the timing of reauthorization requests. In one embodiment, a request to authorize a subscriber of a service to consume a quantity of the service is received and a delay time period is calculated. The delay time period is based on the resources available to the subscriber (e.g., remaining balance in a subscriber account, credit limit, etc.), and/or other configurable thresholds. The subscriber is then authorized to consume the quantity of service over a period of time extending to the time of a service pricing change, plus the delay time period. In this manner, network spikes resulting from the receipt of multiple, simultaneous reauthorization requests at the times of service pricing changes are avoided, without increasing the credit risk to the service operator/provider. | 03-19-2009 |

| 20100067582 | Image Encoding or Decoding Method and Device, with Parallelization of Processing Over Several Processors and Coprocessors, Corresponding Computer-Readable Storage Medium - A method is proposed for encoding/decoding an image having rectangular blocks of pixels. The image has a height of H blocks and a width of W blocks and is divided into vertical (or horizontal) bands of blocks having the height of H (or width of W) blocks. The method includes: obtaining N processors and M coprocessors, the M coprocessors distributed over S levels, N>1, S>0 and M>S; assigning the N processors P | 03-18-2010 |
