Abstract:
The process output value is shifted for performing a pretuning to obtain a coefficient value. A mode 1 is implemented by pulling up the initial input value to an imaginary set point. Then errors are corrected, to obtain an approximate value, and then, an accurate value is obtained. In this way, the input value y(t) is processed to extract the coefficients for a proportionate coefficient value (P), an integral coefficient value (I) and a differential coefficient value (D).
Abstract:
Disclosed is a device for processing an image based on a smart glass. The device for processing an image based on a smart glass comprises an extraction unit which extracts a first object to be observed by a user from a first image received from a smart glass and generates a second image; an information collection unit which collects information related to the first object; and an image generation unit which reconstructs at least one of the second image and the information related to the first image based on the setting of the user.

Abstract:
PURPOSE: A service quality control device of a wireless network and a method thereof are provided to offer content with service quality optimized at a mobile terminal by searching a content node which provides the content to the mobile terminal. CONSTITUTION: A content node searching unit(210) receives a content request signal from a mobile terminal. The content node searching unit searches a content node providing optimized service quality to the mobile terminal. An information providing unit(230) provides the information of the searched content node to the mobile terminal. The content node searching unit searches a content node by using traffic state information, wired network topology information, the wired network connection information. [Reference numerals] (100) Resource allowable control device; (210) Content node searching unit; (220) Network resource setting unit; (230) Information providing unit;
Abstract:
PURPOSE: A method for processing requests/demands for a seamless and high definition service in multimedia communication and a device thereof are provided to guarantee the best performance while efficiently using communication resources. CONSTITUTION: A bearer is added to a basically set bearer to improve the definition degradation and seams of a real time high definition 3D video. A frame rate of a source is reduced in half by separating an odd frame and an even frame. Each stream is separately coded. Therefore, the source is coded with different descriptions. Information is transceived through a DDC(Double Description Coding) technique. [Reference numerals] (AA) 30 fps, 15 fps are examples; (BB) Control according to a Error Event in the unit of GOP
Abstract:
PURPOSE: A music download service providing method is provided to receive the request of broadcasting music through a TV and transmit requested music to a set address. CONSTITUTION: A broadcasting unit transmits an identifier to a broadcasting receiver(S120). The broadcasting unit broadcasts contents to the broadcasting receiver(S130). The broadcasting unit broadcasts a music information message to the broadcasting receiver(S140). The broadcasting unit transmits music data to a music file transmitter(S150). The broadcasting receiver transmits a music request to the music file transmitter(S160). The music file transmitter transmits a music file to a user terminal(S170).
Abstract:
PURPOSE: An apparatus and a method for mutual authentication in downloadable conditional access system are provided to reduce maintenance costs by moving entity authentication based on hardware. CONSTITUTION: An announce protocol processing unit certifies security announce information by using a authentication proxy(200). The announce protocol processing unit transmits the security announce information to a security module(100). A key protocol processing unit relays a key request and a key response. A decoder decodes the key reply information by using the security module. The authentication protocol processing unit decides the identity of the second encryption key and the first encryption key.
Abstract:
PURPOSE: A paring method between SM and TP in a DCAS(Downloadable Conditional Access System), a set-top box and an authentication device using the same are provided to perform a stable pairing operation through the interworking with the TA. CONSTITUTION: In an initialization process, an SM(Secure Micro) and a TP(Transport Processor) exchange security factors with each other. In a validity check process, the TA tests the validity of security factor after receiving the security factor from the SM. As long as the security factor is valid, the SM and the TP generate and exchange a DH(Diffie-Hellman) public key. In an authentication key generation process, the SM and the TP generate and exchange an authentication key, and generates an encoding key in an encryption key generation process.
