Apparatus and method to support encoding and decoding video data
To support encoding a control circuit determines a primary prediction mode to employ when encoding a block of video data and then determines a corresponding companion prediction mode to correspond to the primary prediction mode. The control circuit can then generate a mixed prediction for the block of video data by mixing a prediction formed using the primary prediction mode with a prediction formed using the companion prediction mode.

Video encoding/decoding methods, video encoding/decoding apparatuses, and programs therefor
The computational complexity of a denoising filter is reduced while suppressing a reduction in coding efficiency. In a video encoding/decoding apparatus which uses a loop filter, a deviation degree calculating unit calculates the degree of deviation between a denoising target pixel and a surrounding pixel using a decoded image. A template shape setting unit limits a template shape so that its size is proportional to the degree of deviation relative to the maximum value of the degree of deviation in the decoded image. When noise of the target pixel is removed, weighted in accordance with the degree of similarity between a template of the target pixel and a template of each of search points in a search shape and the weighted sum of pixel values at the search points, the loop filter performs template matching using the limited template shape and removes noise of the target pixel. |

Enabling secure remote assistance using a terminal services gateway
A secure remote assistance session between computers that are behind firewalls and/or NAT devices is provided by an arrangement that uses a terminal services (“TS”) gateway to enable utilization of a remote desktop protocol (“RDP”) connection by a terminal services client in a reverse direction to that used in a conventional terminal services session. The connection is made via a regular TS gateway protocol mechanism by which the TS client behind a firewall establishes a connection to the remote server that is typically behind a firewall that protects a corporate network. The server then functions as the terminal services client to tunnel RDP data through the established TS gateway connection through the NAT firewall to a client. Thus, the server and client reverse roles after the TS gateway connection is made to thereby enable remote viewing of the graphical user interface that is displayed by the client in support of the remote assistance session. |

Secured embedded data encryption systems
Devices generate security vectors based on their own attributes. A device's security vectors compose its transformation matrix. The devices securely share copies of their transformation matrices with other devices. A transmitting device adds its unique MAC to packets, encrypts those packets using its own transformation matrix, and transmits those packets. A receiving device uses its copy of the transmitting device's transformation matrix to decrypt the data in a packet, determining whether a MAC extracted from that packet matches the transmitting device's MAC. The receiving device can permit or prevent further processing of the packet's data depending on whether the MACs match. Each device can store a copy of a same program that can be used to derive derivative security vectors from existing security vectors. Each device in the network can derive the same set of derivative vectors for any selected other device in the network, thereby “evolving” the transformation matrices. |

Method for making a magnetic random access memory element with small dimension and high quality
This invention is about a method to make an MRAM element with small dimension, by building an MTJ as close as possible to an associated via connecting an associated circuitry in a semiconductor wafer. The invention provides a process scheme to flatten the interface of bottom electrode during film deposition, which ensures a good deposition of atomically smooth MTJ multilayer as close as possible to an associated via which otherwise might be atomically rough. The flattening scheme is first to deposit a thin amorphous conducting layer in the middle of BE deposition and immediately to bombard the amorphous layer by low energy ions to provide kinetic energy for surface atom diffusion to move from high point to low kinks. With such surface flattening scheme, not only the MRAM element can be made extremely small, but its device performance and magnetic stability can also be greatly improved. |
