    • A video pre-amplifier for increasing OSD signal colors in a display device and a method thereof includes an OSD interface block, a video signal amplifying block, an IIC bus control unit, and an intensity control unit. An OSD interface block receives the R, G, and B OSD signals, modifies, or levels, the R, G, and B OSD signals in response R, G, and B control signal, and outputs the leveled R, G, and B OSD signals. A video signal amplifying block synthesizes the leveled R, G, and B OSD signals with the R, G, and B video signals, respectively, amplifies the synthesized signals, and generating R, G, and B output signals. An IIC bus control unit controls the interface between a microcontroller and the video signal amplifying block in the display device and generates a predetermined mode signal. An intensity control unit generates the R, G, and B control signals based on combinations of bits of the mode signal and a predetermined intensity control signal. Using the video pre-amplifier and the method of increasing the OSD signal colors, an increase in the number of output pins of the OSD processor and the number of input pins of the video pre-amplifier can be minimized, and an increase in the number of the OSD signal colors is possible.
    • 一种用于在显示装置中增加OSD信号颜色的视频前置放大器及其方法包括OSD接口块,视频信号放大块,IIC总线控制单元和强度控制单元。 OSD接口块在响应R,G和B控制信号中接收R,G和B OSD信号,修改或等级R,G和B OSD信号,并输出调平的R,G和B OSD信号。 视频信号放大块分别与R,G和B视频信号合并级别的R,G和B OSD信号,放大合成信号,产生R,G和B输出信号。 IIC总线控制单元控制微控制器和显示装置中的视频信号放大块之间的接口,并产生预定的模式信号。 强度控制单元基于模式信号和预定强度控制信号的位的组合来生成R,G和B控制信号。 使用视频前置放大器和增加OSD信号颜色的方法,可以使OSD处理器的输出引脚数量和视频前置放大器的输入引脚数量的增加最小化,并且数量的增加 的OSD信号颜色是可能的。

    • The present invention relates to a device and method for managing metadata. A principal object of the present invention is to provide a device and method for managing metadata by which only key metadata can be selected and provided in accordance with their priorities upon playback of audio content by defining attributes of key metadata according to characteristics of the audio content. To achieve this object of the present invention, there is provided a method of managing metadata, comprising the steps of assigning priorities to attributes of key metadata according to characteristics of audio contents, reading the metadata for a specific audio content, extracting the attributes of respective metadata from the read metadata, classifying the extracted metadata attributes according to the assigned priorities and setting their priorities, and displaying the metadata for the audio content according to the set priorities. According to the present invention, there is an advantage in that major information on respective audio content can be efficiently provided to a user based on the metadata that are classified and selected according to the respective audio content.
