Apparatus for interfacing timing information in digital display device |
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.
