摘要： A digital image converting apparatus with auto-correcting phase and a method thereof are provided. The digital image converting apparatus includes a phase controller, a delay locked loop (DLL), an analog-to-digital converter (ADC) and a position adjuster. The phase controller selects one of preset phases for outputting and continuously changes the output preset phase for controlling a clock signal produced by the delay locked loop. The ADC converts an analog display frame according to the adjusted clock signal. After all the preset phases are output in sequence, the phase controller can obtain an optimal phase for converting the display frame according to the smallest front porch of horizontal scan line and the smallest back porch of horizontal scan line of a digital display frame produced by the position adjuster.

摘要： A data transmission system and a transmission method thereof are provided. The data transmission system includes a first electronic apparatus and a second electronic apparatus. The first electronic apparatus includes a first clock pin and a first data pin. The second electronic apparatus includes a second clock pin and a second data pin. In a connecting detection mode, the first electronic apparatus transmits a first detection signal to the first clock pin and drives the first data pin to a reference logic level. The second electronic apparatus transmits a second detection signal to the second clock pin and drives the second data pin to the reference logic level. The first electronic apparatus determines whether the first and the second electronic apparatuses are connected to each other according to whether at least one of signals on the first clock pin and on the first data pin is varied or not.
