Claim Text:
1. A video switch comprising: a first input port, including a first Transition Minimized Differential Signaling (TMDS) transmission channel for transmitting a first TMDS signal and a first Inter-Integrated Circuit (I2C) channel for transmitting a first I2C signal; a second input port, including a second TMDS transmission channel for transmitting a second TMDS signal and a second I2C channel for transmitting a second I2C signal; a first switch unit, coupled to the first I2C channel and the second I2C channel I a second switch unit, coupled to the first TMDS transmission channel and the second TMDS transmission channel, being selectively switched to the first TMDS transmission channel to output the first TMDS signal; wherein when switching from the first input port to the second input port, the first switch unit is selectively switched to the second I2C channel to output the second I2C signal, and after a specified time period during which the first switch unit outputs the second I2C signal, the second switch unit outputs the second TMDS signal.
