摘要： A timing information interfacing apparatus in a digital display device is provided to convert a timing information of a video signal generating unit to a timing information which is substantially requested by a display unit and transmit the converted timing information to the display unit. The timing information interfacing apparatus includes: an decoder for encoding a synchronous signal which is output from the video signal generating part and outputting a multiplexed synchronous signal in which a timing information data is carried; a decoder for decoding the multiplexed synchronous signal of the decoder to separate the synchronous signal and the information signal from the multiplexed synchronous signal and then outputting a demultiplexed timing information data carried in the synchronous signal; and a MICOM for controlling a sampling clock of a phase-locked loop and zoom up/down rates and horizontal/vertical positions of a display signal transforming part depending on the timing information data which is output from the decoder.

摘要： 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.
