Abstract:
Provided is a technique of analyzing particles in real time while collecting and condensing the particles continuously. Gas and/or particles as a detection target substance that are attached to an authentication target 2 are removed by air flow from a blowing region 5. The removed sample is sucked and is condensed and sampled at a sampling region 10, and ions of the sample are generated at an ion source 21 and are then subjected to mass analysis at a mass analysis region 23. Determination of the obtained mass spectrum is made as to the presence or not of a mass spectrum derived from the detection target substance, and a monitor 27 displays a result thereof. Thereby, the detection target substance attached to the authentication target 2 can be detected continuously in real time, promptly and with a less error rate.
Abstract:
In order to avoid content deteriorations caused by embedment of a digital watermark into a moving picture, a process to search a picture for a motion and a process to filter a picture for medical care must be carried out, raising a processing cost. It is thus difficult to implement equipment for processing such pictures at a low cost. In a compound apparatus for encoding compressed code of a moving picture by employing a unit for embedding a digital watermark into a picture, a digital-watermark embedment quantity is determined by using a motion vector and a quantization parameter in a process to embed a digital watermark into the picture. It is thus no longer necessary to carry out the process to search a picture for a motion and the process to filter a picture for medical care for embedment of a digital watermark so that the cost of the entire apparatus can be reduced substantially.
Abstract:
As far as multimedia processing is concerned, a plurality of computations of a same type are often executed concurrently and hence a plurality of computing units having a same function are used and mode information for controlling the plurality of units by an instruction unit for one computing unit is prepared in each instruction to execute a plurality of computations with a single instruction.
Abstract:
An information processing apparatus for realizing coexistence of a high-speed editing function for contents whose copyright is protected and a defending function for limitless movement due to alteration of the contents and a defending function for an illegal process using power-off. When the contents constructed on a block unit basis is received and division-edited, block unique information as unique information corresponding to each divided block is formed. Apparatus unique information to specify the apparatus is recorded into a memory or the like. A Hash value which is formed from the formed block unique information and the apparatus unique information which has previously been stored in the memory or the like is stored.
Abstract:
A digest image preparation apparatus includes an image coding circuit for receiving a moving picture to output a coded image obtained by coding the moving picture and extracting a certaing feature parameters produced upon the coding to be outputted, a feature vector computation circuit for receiving the feature parameters to output feature vectors of image frames defined in n dimensions and a curve simplification circuit for simplifying loci generated by arranging the n-dimensional feature vectors outputted by the feature vector computation circuit in time series manner to output ranking information. It then becomes possible to reduce a necessary cost for the image coding and a ranking information calculation.
Abstract:
Disclosed is a digital broadcasting receiving apparatus configured such that software served to control the behavior of the apparatus is divided into two pieces of software: a small piece of dedicated software (a) served to control a tuner and a large piece of software (b), i.e. main software, and that when the apparatus is switched on, the software (a) is first activated to perform received frequency setting, and in parallel with the receiving processes of the tuner, the software (b) is activated and executed. The apparatus can reduce the time required for a user to begin to watch images and listen to sounds after the apparatus is switched on.

Abstract:
An object of the present invention is to provide a function to make a reservation for recording or watching with a simple operation during watching a program promotion, by adding a function to acquire the information required to make a reservation from the program promotion being watched. For the achievement of the object, a character recognition processing unit and an audio recognition processing unit extract keywords from video information and audio information contained in video information. Then, after the keywords are transferred to a keyword managing unit, a program information processing unit appropriately shows the program information to an operator. The operator can make the reservation simply by selecting the presented program information.
Abstract:
A technique for distributing digital contents capable of effectively protecting copyrights and the like on the basis of invisible electronic watermark information and electronic watermark information is to be provided. On the sending side, additional information including copyright-related information is embedded into digital contents in advance as invisible electronic watermark information, while on the receiving side, additional information as the embedded invisible electronic watermark information is decoded and extracted as visible watermark information, the extracted information is embedded again into the digital contents, and the additional information is distributed or outputted as visible information together with the digital contents.
Abstract:
In the case of constituting a processing unit having the characteristic of a VLIW type processing unit and the characteristic of a pipeline type processing unit, since reference to the result of operations is made among a plurality of processing units executing in parallel the operations, transfer of the register file is frequently generated among the processing units, resulting in insufficient effect of the high speed operations. In view of solving this problem, the predicate registers are provided and moreover a means for broadcasting the update data of the predicate register to all processing units is also provided. Thereby, operations for obtaining branching condition and numerical value can be realized in different processing units and the number of steps of the processing program can be reduced. In addition, since high speed transfer between the processing units of the data register having a wider bit width is no longer required and thereby the mounting area can be reduced and high speed processing unit can be realized.
