Abstract:
The present invention discloses a home network system using a living network control protocol. The home network system includes: at least one new device including a node address having an initial logical address through a network based on a predetermined protocol, transmitting a configuration request message having the node address to a master device, receiving a temporary address setting request message, changing the initial logical address by selecting one temporary logical address, generating a temporary address setting response message, transmitting the temporary address setting response message to the master device, receiving an address change request message having a predetermined logical address from the master device, changing the temporary logical address into the received logical address, and having a unique node address; and at least one master device for receiving the plurality of configuration request messages from the new device, setting the temporary logical address range for the new device, transmitting the temporary address setting request message having the set temporary logical address range to the new device, receiving the temporary address setting response message from the new device, setting the predetermined logical address of the new device, and transmitting the address change request message having the set logical address to the new device of the selected temporary address.
Abstract:
The present invention discloses a home network system using a living network control protocol. The home network system includes: at least one electric device; first and second networks based on a predetermined living network control protocol (LnCP); an LnCP access device connected to the electric device through the second network; and a network manager connected to the LnCP access device through the first network, for controlling and monitoring the electric device.
Abstract:
A white light semiconductor light emitting device includes a semiconductor LED and first and second phosphors provided on a light emitting region of the LED to emit light within a first wavelength range, which is different from that of light emitted from the LED, by absorbing a portion of the light emitted from the LED. The first and second phosphors are respectively a barium-silicate-base green phosphor and a zinc-selenium-base red phosphor.
Abstract:
The present invention relates to a preparation method of sitagliptin, and more particularly, to a method of preparing sitagliptin using L-aspartic acid having a (R)-beta amino acid structure by mild amide formation, by the use of industrially applicable halo isopropylmagnesium, and by removal of amine protecting group using Pd/C and H2 and carbonyl reduction using reducing agent.
Abstract:
The present invention relates to a method for providing a multi-view still image service, which involves configuring a multi-view still image file format including a plurality of image areas into which a plurality of pieces of image information are to be inserted so as to form a multi-view still image, inserting the plurality of pieces of image information into the plurality of image areas, respectively, inserting basic 3D attribute information for reproducing the multi-view still image in three dimensions into an image area into which main-view image information is inserted, and outputs multi-view still image data including the plurality of pieces of image information on the basis of the multi-view still image file format.
Abstract:
Disclosed is a method for generating a broadcast bit stream for caption providing digital broadcasting, wherein the method involves: inputting video data in which a video comprising two-dimensional video and/or three-dimensional video is encoded; determining caption data to be reproduced together with video, and three-dimensional captioning information containing information on the conversion speed of an offset for reproducing the caption data as three-dimensional captions; and multiplexing the encoded video data, caption data, and three-dimensional captioning information so as to output a bit stream for digital broadcasting.
Abstract:
The present invention relates to novel Forms A, B, C, D, E, F and G of crystalline 9-[2-[phosphonomethoxy]ethyl]adenine bis-pivaloyloxymethyl ester, i.e., adefovir dipivoxil, and processes for preparing them. According to the present invention, said novel crystal forms having a high purity can be obtained by a simple method and in a high yield.
Abstract:
A home appliance and home appliance system are provided which enable a portable terminal not to recognize an acoustic signal sound corresponding to product information output by the home appliance as noise. Thus, the acoustic signal corresponding to product information output by the home appliance may be transmitted to a service center through the portable terminal. The home appliance may include a controller that sets a dead time at a predetermined interval of time with respect to a signal corresponding to product information to avoid a noise detection section of a portable terminal, a converter that converts the signal into an acoustic signal of a predetermined band, and a sound output device that outputs the acoustic signal as sound.

Abstract:
A home appliance system and an operation method thereof are disclosed. The home appliance outputs product information as a predetermined sound and transmits the sound through a connected communication network, thereby making it easier for a service center at a remote place to check a status of the home appliance. Further, the home appliance system and operation method thereof prevents noise or signal error generated in the procedure of converting product information into a signal of a predetermined frequency band in order to output the product information as a sound, thus enabling stable signal conversion and improving the accuracy of information transmission using the output of sound.
