Abstract:
PURPOSE: An image compression standard determination method is provided to encode a low quality image by determining an image compression standard based on the resolution of the low compression standard. CONSTITUTION: An image compression standard determination apparatus encodes a high quality image(210). The image compression standard determination apparatus determines an image compression standard(220). The low quality image is encoded by the determined image compression standard in case the average power of quantization noise in the encoded low quality image is under than the average power of the quantization noise in the encoded high quality image(230,240). The image compression standard determination apparatus transmits streams for the encoded low quality image to a second channel(260).

Abstract:
PURPOSE: Apparatus and method for coordinating an operation action of robot software components are provided to prevent the malfunction of components caused by an execution sequence by defining the dependability between the components. CONSTITUTION: A profile analyzer(22) analyzes the execution dependency information of components defined in an execution control profile. A component manager(24) arranges the components according an execution sequence of components caused by the execution dependency information. An execution control manager(26) determines the execution practicability on a basis of the execution dependency information of the components. An execution unit(28) executes the components according to the determined results.
Abstract:
PURPOSE: A fault tolerance method and device in the execution of a robot software component is provided to prevent that the malfunction of a specific component is expanded to the malfunction of the whole system while keeping the system performance when executing a robot multi software component. CONSTITUTION: A component executor(100) executes a robot software component with the same priority and cycle. An executor monitor(200) periodically monitors the operation of the component executor and decides the malfunction of the robot software component. An executor manager(300) assigns the robot software component with the same priority and cycle, and generates the component executor. If the malfunction of the component executor is decided, the executor manager generates new component executor.
Abstract:
PURPOSE: A remote plug in device, a robot plug in execution engine device and robot plug in execution system are provided to enable a robot to effectively use a computing resource by allocating a function module of a robot software to a distributed computing nodes. CONSTITUTION: An object manager(111) manages a remote object of a remote plug-in inside. A symbol, function, notification and timer service manager(112~115) register and manger the functions, information, and timer.
Abstract:
PURPOSE: A system and a method for measuring performance of identifying a face by an intelligent robot are provided to objectively measure performance of identifying a face by an intelligent robot, thereby obtaining reliability in performance measurement of a component development company, a component buying company, or a consumer. CONSTITUTION: A test environment preparing device(100) prepares a test environment. A face identifying system(200) performs image capture, image preprocessing, face region extraction, face element extraction, personal identification, and recognition result output. A user tracking success rate analyzer(300) outputs a successful face region extraction frequency. A user tracking speed calculator(400) calculates a final user tracking speed. An output device(500) outputs performance.
Abstract:
PURPOSE: An unmanned transport apparatus and a method thereof are provided to prevent the error from detecting the distance to a destination location, and to economically install the apparatus. CONSTITUTION: An unmanned transport apparatus(100) comprises a calling unit(10), a navigation guide unit(20), an image recognition unit(30), and a controller(40). The calling unit supplies destination information by the calling signal from a communications device(S6). A navigation guide unit recognizes the current position by using a digital map(S1), and detects an optimal path to the destination.
Abstract:
PURPOSE: By using the size of the QAM symbol the frame synchronization method and apparatus thereof can show the excellent frame synchronization performance regardless of the carrier frequency deviation. CONSTITUTION: The sync pattern which uses the size by using the QAM symbol size is composed(710). The received vector in which the size is computed in order to symbol-by-symbol and using the size is composed(714). The frame synchronization obtains based on correlation between the sync pattern using the size and the received vector using the size. In correlation between the sync pattern using the size and the received vector using the size, calculation operates(720). Correlation decides the estimate in which the operation result most highs with the start range of frame and the frame synchronization obtains.
Abstract:
PURPOSE: An ultra high definition DVD recording device and reproducing device and a control method of the devices are provided to enable store and reproduce 4K-over video and multi channel audio by applying the synchronization function between separated data. CONSTITUTION: A control method of the ultra high definition DVD recording device comprises next steps. Each of audio data, video data, and caption data are divided to a plurality of sections. The sampling rate of a plurality of audio data is varied or at least one of the frame rate, the color space, and the chromacity type of a plurality of video data is varied. An optical writer(115) storing data in a recording media is controlled to store the title information and the and separation information of a plurality of audio data, a plurality of video data and a plurality of caption data, a plurality of audio data, a plurality of video data, and a plurality of caption data are stored in the recording media.
Abstract:
PURPOSE: A method port apparatus and a composition method for a robot software component are provided to call up a method for calling up a specific function of a component in a circumference in which class implementation is different in order to enhance the reliability in the development. CONSTITUTION: A remote method agent module(112) performs a message encoding and decoding function for a remote method call. When a second component provider method port corresponding to a requestor method port module exists in a remote place, a method port connector module(114) performs inter-component communication by configuring an inter-port message format. A method port management module processes the searching request for the provider method port or inter-port connection.
