    • Disclosed herein are a broadcast signal retransmission system and method using illuminating visible-light communication. The broadcast signal retransmission system comprises one or more light-emitting diode (LED) lighting fixtures, one or more smart communicators, and a home server. The home server receives and demodulates a multi-channel broadcast signal and, in reply to a signal request message from a smart communicator, transmits a demodulated broadcast channel signal through a power line to an LED lighting fixture indicated by the signal request message. The LED lighting fixture converts the broadcast channel signal into a light signal. The smart communicator receives the light signal from the LED lighting fixture and decodes the light signal into a broadcast signal. As a result, the user can selectively receive a broadcast signal of a desired channel using a smart communicator via a nearby LED lighting fixture.
    • 这里公开了使用照明可见光通信的广播信号重传系统和方法。 广播信号重传系统包括一个或多个发光二极管(LED)照明灯具,一个或多个智能通信器和家庭服务器。 家庭服务器接收并解调多信道广播信号,并且响应于来自智能通信器的信号请求消息,通过电力线将解调的广播信道信号发送到由信号请求消息指示的LED照明装置。 LED照明灯具将广播频道信号转换为光信号。 智能通信器从LED照明灯具接收光信号,并将光信号解码为广播信号。 结果,用户可以经由附近的LED照明灯具使用智能通信器选择性地接收期望频道的广播信号。

    • Methods and apparatuses for providing DRM interoperability are provided. Proxy re-encryption technique using bilinear map is used, and the same content can be used in different devices. According to the method of providing DRM interoperability includes in proxy agent with respect to digital rights management (DRM) service providers and device which supports predetermined DRM, first DRM service provider, second DRM service provider, the proxy agent, and the device identify each other, and proxy re-encrypt an interoperable content (IC) and provide the IC to the device. The IC is second-level encrypted by using a key of the first DRM service provider, and the proxy re-encryption is performed by using a proxy key generated from proxy key information provided from the first DRM service provider and the second DRM service provider. Therefore, a problem in which interoperability cannot be guaranteed since a DRM technique depends on a service provider is resolved.

    • A liquid crystal display for recognizing a flicker with the naked eyes in a step of inspecting a flicker in the case where a liquid crystal display is driven with a frame frequency of 120 Hz is disclosed. In the liquid crystal display, a timing controller supplies a first frame inversion polarity signal which is used at a first frame inversion and, at the same time supplies a gate start pulse which indicates a supply of a scanning pulse. A frame polarity signal converting means converts a first frame inversion polarity signal into a second frame inversion polarity signal in response to the gate start pulse. And a data driver changes the inputted frame into a second frame inversion in response to the second frame inversion polarity signal.
