An electronic apparatus is provided. The electronic apparatus performs two-way communication with a remote control device, and includes a receiving unit which receives a data signal from the remote control device, a signal processing unit which performs signal processing to convert the received data signal into a pulse signal and a control unit which detects information included in the data signal based on a time interval between starting points of pulse periods which are in a row in the pulse signal.

Electronic apparatus and method for detecting information using the same

An image recording/reproducing apparatus and a control method thereof to provide the functions of recording image files in a recording medium and reproducing and editing the image files recorded in the recording medium. The apparatus and method enables a user to easily select and manipulate functions of the apparatus using a menu display, and can record, reproduce and edit the image files according to the function selected by the user. The apparatus and method, therefore allows the user to easily select and manipulate the functions using a displayed menu, and more efficiently manage and easily search for the recorded image files.

Image recording/reproducing apparatus and control method thereof

An image recording/reproducing apparatus includes a first device for reproducing data from a recording medium, a second device for recording the data reproduced by the first device, a data maintenance unit for controlling the operation of the first and the second devices, a power supply unit for supplying a power to the first and the second devices, a power control unit for controlling operation of the power supply unit, an error data detecting unit for detecting an error data among the data recorded in the second device, and a main control unit, which, upon receiving a power cut-off command, controls the data maintenance unit to stop the operation of the second device and delete the error data detected by the error data detecting unit. Then, with the deletion of the error data, the main control unit controls power control unit so that the power supply unit cuts off the power supply. With the input of the power-off command, error data is detected among the data recorded in the recording space of the hard disc drive and deleted. Accordingly, the system is always maintained at an optimum state.

Image recording/reproducing apparatus for system optimization

A frequency modulation (FM) recording apparatus for recording an FM modulated video signal onto a recording medium is provided. This recording apparatus (luminance components plus color components) includes an automatic gain controller; a limiter for limiting the level of a luminance component output from the automatic gain controller; a recording equalizer for equalizing the output from the limiter in accordance with the characteristics of the recording medium; a color low-pass filter for filtering and transmitting a color FM signal in an FM modulated video signal output from the automatic gain controller; and a mixer for mixing the luminance component output from the recording equalizer with the color component output from the color low-pass filter. The FM recording apparatus adopts an automatic gain controller for correcting an imbalance in the levels of playback FM signals between channels, and enabling FM recording with superior image.

Frequency modulation (FM) recording apparatus of video tape recorder

An apparatus and method for controlling copying of a video signal are provided for detecting a copy preventing signal, and for stopping recording and informing the user that a video signal to be recorded is protected against copying when a video signal having a copy-preventing signal is detected. In the apparatus and method, a copying (or recording) mode is stopped, and the user is informed that a recording medium to be copied is protected against illegal copying when a copy-preventing signal is detected from a video signal reproduced from the recording medium to be copied, thereby allowing the user to quickly recognize that the recording medium to be copied includes a copy-preventing signal before completing the copying. In addition, when the apparatus and method are applied to a dual deck VCR, FM copying can be controlled depending on whether a macrovision signal exists on the basis of the beginning date on which the aggressive protection of copyright becomes effective.
