Communication device and communication method

Abstract: A communication device for performing communication by employing first and second communication units, includes: a reception unit for receiving a communication packet including a random number generated for every connection with another communication device, a certificate calculated with the random number, and authentication method information indicating whether or not an authentication method at the second communication unit is compatible with the public key system, through the first communication unit; and a method determining unit for determining whether or not an originator of the communication packet accepts public key encryption based on the authentication method information included in the communication packet; wherein in a case of the method determining unit determining that the originator of the communication packet does not accept the public key system, the random number included in the communication packet is replied to the originator as the identification information of the device itself.

System and method of selective media content access through a recommednation engine

Abstract: A personalized entertainment and information platform (Sphere) which provides personalized content delivery across different platforms and modes of delivery. A personal media device (e.g., PC, television, and so forth) interacts with a control server configured for accessing media content and metadata over the Internet. In response to input from the user and the history of user media selection and viewing, a prioritized recommendation list is generated and queued for downloading. The associated content is then downloaded automatically to the personal media device, without the need of user interaction. At this time the user can access the downloaded content immediately without a lengthy delay in waiting for content downloading. It will be appreciated that content such as shows and movies in HD format are of significant size (e.g., up to 50 GB) which would require significant download time, and tie up network and system resources.

Color display device

Abstract: A color display device such as an active-matrix type liquid crystal display apparatus has a first substrate having pixel electrodes arranged in the form of the matrix, switching elements associated with respective pixel electrodes and color filters aligned with the respective pixel electrodes. The first substrate is composed of a laminate structure including, superposed in the mentioned sequence, a first layer having the switching elements, a second layer having the color filters, a third layer including a planarization film which fills convexities presented by the switching elements and the color filters, and a fourth layer having the pixel electrodes aligned with the color filter. The display device also has a second substrate including a counter electrode and adjoined to the first substrate leaving a predetermined gap left therebetween. A liquid crystal is charged in the gap between the first and second substrates.

HEVC Deblocking Filter

Abstract: This paper describes the in-loop deblocking filter used in the upcoming High Efficiency Video Coding (HEVC) standard to reduce visible artifacts at block boundaries. The deblocking filter performs detection of the artifacts at the coded block boundaries and attenuates them by applying a selected filter. Compared to the H.264/AVC deblocking filter, the HEVC deblocking filter has lower computational complexity and better parallel processing capabilities while still achieving significant reduction of the visual artifacts.

Natural language interface control system

Abstract: A natural language interface control system (206) for operating a plurality of devices (114) consists of a first microphone array (108), a feature extraction module (202) coupled to the first microphone array, and a speech recognition module (204) coupled to the feature extraction module, wherein the speech recognition module utilizes hidden Markov models. The system also comprises a natural language interface module (222) coupled to the speech recognition module (204) and a device interface (210) coupled to the natural language interface module (222), wherein the natural language interface module is for operating a plurality of devices coupled to the device interface based upon non-prompted, open-ended natural language requests from a user.
