20090012939 | Information Presentation Method and Apparatus - A method of extracting a keyword in synchronism with a “scene” or “corner” in a TV program that changes in units of second in synchronism with the elapse of time of first content, and an information presentation apparatus to search and display a predetermined form of content, such as a web page, are provided. The information presentation apparatus comprises: an AV content output unit to output AV content (e.g., TV programs and movies); and a web page output unit to output, together with the AV content from the AV content output unit, a web page that corresponds to a keyword related to a scene included in the content being output from the AV content output unit without the user having to take trouble to choose a keyword, the web page output unit being adapted to, when the scene in the content changes, automatically update the web page to one corresponding to the changed scene. | 01-08-2009 |
20110216661 | Communication Control Device and Communication Quality Measurement Method - Disclosed is a communication control device for measuring the delivery quality of unicast/multicast video delivery by a user premises device. The communication control device connects a first network to a second network. The first network is connected to a delivery server for delivering data packets containing plural pieces of content. The second network is connected to a plurality of computers for acquiring the data packets from the delivery server. The communication control device acquires control information that is transmitted from the computers to the delivery server, extracts computer identification information and data packet identification information from the acquired control information, and measures the delivery quality of data packets targeted for measurement, which are to be transmitted to the identified computers, in accordance with the extracted computer identification information and the extracted data packet identification information. | 09-08-2011 |
20110280305 | IMAGE PROCESSING DEVICE, DECODING METHOD, INTRA-FRAME DECODER, METHOD OF DECODING INTRA-FRAME AND INTRA-FRAME ENCODER - Adopted is a decoder, in which on condition that a prediction block shown by vector information extracted from a data stream, and a decode-target block have an overlap where respective pixels overlay each other, pixel information of an already-decoded portion at a distance of an integer multiple of a vector provided by the vector information from the overlap is made a prediction signal instead of the overlap, and the prediction signal is added to difference image data taken from the data stream to generate reproduction image data. The decoder is adopted for an intra-frame decoder, a local decoder of an encoder, and the like. According to a fundamental rule concerning a repetitive pattern of an image, a pixel at a distance of an integer multiple is a like pixel, and therefore the process of decoding can be performed efficiently. | 11-17-2011 |
20110305280 | COMPRESSED DYNAMIC IMAGE ENCODING DEVICE, COMPRESSED DYNAMIC IMAGE DECODING DEVICE, COMPRESSED DYNAMIC IMAGE ENCODING METHOD AND COMPRESSED DYNAMIC IMAGE DECODING METHOD - A compressed dynamic image encoding device is provided, in which a motion vector is generated by searching a reference image read from a frame memory for an image area most similar to an image area of a video input signal; a motion-compensated reference image is generated from the motion vector and the reference image read from the frame memory; a prediction residual is generated, by subtracting the motion-compensated reference image from the video input signal; the reference image to be stored in the frame memory is generated, by adding the motion-compensated reference image and the result of processing of orthogonal transform, quantization, inverse quantization, and inverse orthogonal transform performed to the prediction residual; and an encoded video output signal is generated by the processing of orthogonal transform, quantization, and variable-length encoding performed to the prediction residual. The reference image comprises on-screen reference images A, B, and C, located inside a video display screen, and an off-screen reference image D located outside the video display screen, and the off-screen reference image D is generated based on the positional relationship of plural similar reference images A and B of the on-screen reference images A, B, and C. | 12-15-2011 |
20120317442 | EMBEDDED DEVICE AND EMBEDDED SYSTEM - The redundancy that is effected by preparing a plurality of units of hardware of an identical configuration results in high costs, complicating the application of same to inexpensive products. The present invention detects a fault in a function that is provided via hardware upon an apparatus having a variety of components, such as a CPU, capable of changing content to be processed at the application level, and an FPGA, capable of changing the content to be processed. When a fault is thus detected, the invention uses configuration information of an apparatus either within the apparatus or within apparatuses upon the network to select an apparatus capable of serving as a substitute, selects software required to implement the function, carries out procedures for facilitating the use of the software upon the substitute hardware (i.e., downloading the software, loading the software into a memory region accessible to the hardware), and carries out the processing in substitution. | 12-13-2012 |
