Abstract
A server utilizes a BMC to divide a video source signal into original analog and digital component signals, and stores the digital component signal in a set of registers of a duplicator. An ADC converts the original analog component signal into a converted digital component signal, which is stored in another set of registers of the duplicator. A switch set of the duplicator is switched to output a pair of the converted and the original digital component signals. One DAC converts the converted digital component signal into a converted analog component signal, which together with the original digital component signal, serves as a duplicated video signal.
Claims20
A server with a capability of duplicating a video source signal to obtain a plurality of duplicated video signals to be outputted to a plurality of display devices, said server comprising:
- a baseboard management controller (BMC) configured to receive the video source signal, and to divide the video source signal into an original analog component signal and an original digital component signal;
- and
- a duplicator electrically connected to said BMC, and including
- an analog-to-digital converter (ADC) which is configured to convert the original analog component signal into a converted digital component signal, and to output the converted digital component signal,
- a plurality of first registers which are electrically connected to said ADC, which respectively correspond to the display devices, and each of which is configured to receive the converted digital component signal and to store the converted digital component signal,
- a plurality of second registers which respectively correspond to the display devices, and each of which is configured to receive the original digital component signal and to store the original digital component signal,
- a switch set which is electrically connected to said first registers and said second registers, which is configured to, for each of the display devices, be triggered by a trigger signal to switch from a non-conductive state to a conductive state to output the converted digital component signal that is stored in one of said first registers corresponding to the display device and to output the original digital component signal that is stored in one of said second registers corresponding to the display device, and
- a plurality of digital-to-analog converters (DACs) which are electrically connected to said switch set, which respectively correspond to the display devices, and each of which is configured to convert the converted digital component signal outputted by said switch set for a respective one of the display devices into a converted analog component signal,
- wherein, for each of the display devices, the converted analog component signal and the original digital component signal cooperatively serve as one of the duplicated video signals to be outputted to the display device for displaying thereon.
