An encoder includes a precoder for encoding an input information object according to a preset encoding scheme and storing the encoded information object in a precoder buffer, a sample number/address generation unit for generating a sample number of each sample and an address, which corresponds to each bit of each sample and the address of the precoder buffer, a multiplexer for selecting a bit of the precoder buffer corresponding to the address generated by the sample number/address generation module, a sampling buffer for storing a bit of each sample output from the multiplexer, a control packet generation module for generating a control packet including information on the sample number generated by the sample number/address generation module, a packet assembling unit for assembling the sample stored in the sampling buffer with the control packet generated by the control data generation module, and a modulation module for modulating the packet output from the packet assembling unit into a sound signal according to a preset scheme.
摘要:
In a digital broadcasting system comprising a server for retransmitting a digital broadcast on the basis of an Internet protocol (IP), a user terminal for receiving the digital broadcast on the basis of the IP, and a router for connecting the server with the user terminal, the server performs a method for providing the broadcasting channel information that includes the steps of dividing a broadcasting stream to be transmitted to the user terminal into the broadcasting channel information and other information excluding the broadcasting channel information by demultiplexing the broadcasting stream and extracting the broadcasting channel information from the divided broadcasting stream, converting the extracted broadcasting channel information into IP-based broadcasting channel information by inserting the Internet protocol information for each broadcasting channel into the extracted broadcasting channel information, and remultiplexing the IP-based converted broadcasting channel information and the other information and transmitting the remultiplexed information to the user terminal.
摘要:
Disclosed is a gain-controllable wideband optical fiber amplifier for amplifying both C-band and L-band optical signals, which comprises: a first amplifying section configured to (1) be pumped in at least one direction, (2) amplify both C-band and L-band optical signals and (3) output an amplified spontaneous emission; an optical attenuator for attenuating the power of the spontaneous emission; and a second amplifying section pumped by the attenuated spontaneous emission to secondarily amplify the amplified L-band optical signals.
摘要:
A wireless charging method and apparatus wirelessly charges power between separate electronic appliances. The wireless charging method includes searching for at least one chargeable electronic device, receiving status information from the searched at least one electronic device, determining whether the electronic device is a power supply electronic device or a power demand electronic device, receiving a supply of power from the searched at least one electronic device if the electronic device is determined to be the power demand electronic device, and supplying the power to the at least one electronic device if the electronic device is determined to be the power supply electronic device.
摘要:
A mobile terminal and a method for wirelessly charging the mobile terminal are provided. The method includes searching for a wirelessly rechargeable mobile terminal; receiving, upon finding a wirelessly rechargeable mobile terminal, power state information from the found rechargeable mobile terminal; setting the mobile terminal as one of a power supplying terminal and a power receiving terminal based on the received power state information; and performing a power charging operation with the found rechargeable mobile terminals according to the setting.
摘要:
An apparatus and method for providing an AR service using a sound. When a user starts an AR service providing function in a mobile communication terminal, a sound signal is received, whether the sound signal is carrying additional information is determined by analyzing the sound signal, if the additional information is carried on the sound signal, the additional information is extracted, data associated with the extracted additional information is acquired, and the AR service is provided using the acquired data. Accordingly, various kinds of additional information may be provided, and the AR service may be provided.
摘要:
A method for transmitting, by a mobile device, a data object, is provided, and includes estimating expected transmission times required for transmitting an object between devices by an acoustic communication link and supported radio interfaces, based on a size of the object, transmitting the object through an acoustic communication channel when the link is estimated to provide a shortest expected transmission time, and determining rankings of the radio interfaces according to the expected transmission times when the acoustic communication link does not provide a shortest expected transmission time, transmitting rankings information and configuration information on the supported radio interfaces through the acoustic communication channel by a configuration container, and transmitting the object through a radio interface through which a response is received.
