Abstract:
PURPOSE: A network synchronization apparatus of a mobile communication system base station is provided to reduce the cost and compensate for an error when the error occurs in a network synchronization apparatus by separating an oscillator from a GPS receiver so that GPS receivers common use one oscillator. CONSTITUTION: A plurality of GPS receivers(111,117) receive a plurality of GPS signals, correct an error with respect to the GPS signals and output a reference signal, The GPS receivers(111,117) divides an inputted output signal and provide a synchronous signal to a base station. An oscillator(116) outputs the output signal according to the reference signal from the GPS receivers(111,117) to the GPS receivers(111,117). A GPS engine(112) receives the plurality of GPS signals from a plurality of satellites. A digital phase locked loop controller(113) senses and corrects an error with respect to the GPS signals. A variable frequency oscillator(114) multiplies, decreases, or mixes an oscillating frequency based on the output signal from the oscillator(116) and outputs a stable frequency.

Abstract:
A side emitting lens, a backlight unit, and a liquid crystal display having the same are provided to reduce a material cost by reducing the number of light emitting diodes. A side emitting lens(450) is formed with a dome-shaped body. The dome-shaped body includes a base part(460), a refractive part(470), and a reflective part(480). The base part receives incident light from the outside. The refractive part refracts the external light and outputs the refracted light to a side. The reflective part reflects totally the incident light to at least one of the refractive part and the base part. The reflective part is a cone-shaped groove which is formed at a center region of the refractive part. The reflective part is formed with three or more reflecting surfaces.
Abstract:
An apparatus and a method for reproducing a recorded program are provided to convert a broadcasting program recorded in a data storage device into a broadcasting signal and transmit the broadcasting signal to a TV receiver to allow a user to view the recorded program easily. An apparatus for reproducing a recorded program includes a tuner(10-1), a recorder(10-3), a controller(10-5), and a digital broadcasting signal converter(10-4). The tuner receives a broadcasting signal. The recorder records the broadcasting signal on a recording medium. The controller manages channel allocation and playback schedule with respect to broadcasting programs recorded on the recording medium. The digital broadcasting signal converter converts a broadcasting program reproduced by the recorder into a digital broadcasting signal of a channel allocated by the controller.
Abstract:
A method and an apparatus for processing contents are provided to allow users to easily reproduce desired files through switching of channels by allocating network contents to empty channels to which broadcast signals are not allocated. The first and the second channel information are respectively stored(420). The first channel information relates to empty channels to which broadcast signals are allocated, and the second channel information relates to channels to which broadcast signals are not allocated. A request for a content list is transmitted to server devices connected to a home network(430). The content list is received from the server devices(440). The received content list is mapped to the empty channels(450). When one of empty channels to which the content list is mapped is selected, contents corresponding to the selected channel are reproduced(488).
