Abstract: Disclosed is an image encoder that divides a digital image into a set of “macroblocks.” Each macroblock is encoded by applying spatial (and possibly temporal) prediction. The “residual” of the macroblock is calculated as the difference between the predicted content of the macroblock and the actual content of the macroblock. The residual is then “decimated” by taking an orderly subset of its values. The decimated residual is then either transmitted to an image decoder or is stored for later use. To recreate the original image, the macroblocks are first recreated from their received residuals. When a decimated residual is received, the values of the residual left out during decimation are interpolated from the values actually received. Using the prediction techniques along with the residual, the original content of the macroblock is recovered. The macroblocks are then joined to form the original digital image.

Abstract: Disclosed is an image encoder that divides a digital image into a set of “macroblocks.” If appropriate, a macroblock is “downsampled” to a lower resolution. The lower-resolution macroblock is then encoded by applying spatial (and possibly temporal) prediction. The “residual” of the macroblock is calculated as the difference between the predicted and actual contents of the macroblock. The low-resolution residual is then either transmitted to an image decoder or stored for later use. In some embodiments, the encoder calculates the rate-distortion costs of encoding the original-resolution macroblock and the lower-resolution macroblock and then only encodes the lower-resolution macroblock if its cost is lower. When a decoder receives a lower-resolution residual, it recovers the lower-resolution macroblock using standard prediction techniques. Then, the macroblock is “upsampled” to its original resolution by interpolating the values left out by the encoder.

Abstract: A method of resource sharing between a plurality of communication networks each having a nominal resource allocation of a shared air interface resource and a resource exchange allowance is provided. A temporary resource allocation of a first air interface resource from a nominal resource allocation of a first network is initiated (403). Subsequently, a plurality of offer rounds are executed (405) with each offer round comprising determining offer values for the first air interface resource. A second network is then selected (407) in response to the determined offer values and subsequently a resource allocation message is transmitted (409) to the second network. The resource allocation message indicates a temporary allocation of at least part of the first air interface resource from the first network to the second network. Consequently, the resource exchange allowance of the second network is reduced (411) accordingly. Each offer round comprises receiving new offer values from the first plurality of networks.

Abstract: Communication nodes, acting as intermediate routers for communication packets transmitted between a source node and a destination node, are provided with different access rights to the fields of the routed communication packets. Routes of intermediate routers between the source node and the destination node are discovered and the identities of intermediate routers on the discovered routes are collected. The aggregate trust levels of the intermediate routers are computed allowing the most trusted route to be selected. Encryption keys are securely distributed to intermediate routers on the most trusted route based on the trust level of the intermediate routers and fields of the communication packets are encrypted with encryption keys corresponding to the assigned trust level. Intermediated nodes are thereby prevented from accessing selected fields of the communication packets.

Abstract: A user preference profile apparatus comprises a receiver (301) which receives preference indications from a plurality of devices (101-105) which have different device characteristics. The received preference indications are implicit preference indications reflecting user actions for content items. A relation processor (305) provides device dependent relations for devices where each device dependent relation defines a calculation of a device content item preference as a function of at least one preference indicator from the corresponding device. A preference processor (303) generates a device content item preference for content items and devices in response to received preference indications for the content items and devices and the corresponding device dependent relation. A user profile processor (307) then modifies a user preference profile in response to the content item preferences.

Abstract: In a wireless communication system wherein a user equipment (UE) that accesses a cell served by an access point (sometimes known as femtocell) is granted only a limited time period during which to camp on, attach to, or connect to the cell, the communication system permits a user of the UE to anticipate an expiration of the time period and, if desired negotiate an extension of the time period. More particularly, the communication system provides for notification of the UE of the duration of this limited time period and further permits the UE to negotiate an extension of the time period when the UE desires to do so. In the event an extension is requested by the user and granted by the owner/operator, a notification will be sent to the user and the UE may reset a timer.

The user interface produces an input signal in response to detecting a predetermined gesture at the touch-sensitive surface. The transceiver communicates wirelessly with a remote device and terminates communication with the remote device in response to the input signal from the user interface. The device determines that it is communicating the remote device, detects the predetermined gesture at the touch-sensitive surface, and terminates communication with the remote device in response to detecting the predetermined gesture while communicating with the remote device. The predetermined gesture includes continuous contact at the touch-sensitive surface between discrete locations of the surface.

Abstract: A mesh station applying for access to a network includes a list of peer stations in messages of an authenticated key establishment protocol. A mesh key distributor derives a key delivery key and generates a top level key, and then delivers the top level key to the mesh station. Following the key establishment protocol, the mesh key distributor also creates pairwise keys for use between the mesh station and the peer stations listed in its peer list. The list of peers permits the identifier for the peer to be bound into the derived key, which helps ensure that the key used between each pair of peers is unique. Once the mesh key distributor finishes creating a key for one of the stations on the peer list, the mesh key distributor sends a message to the peer to initiate a key push.
