Claim Text:
1. A digital television chip for converting analog signals into digital signals, wherein the digital television chip receives a first group of signals comprising a couple of S-video signals SY and SC, a second group of signals comprising a couple of Tuner CVBS signals VIF and SIF and a third group of signals comprising a CVBS Line-in Video signal, and the digital television chip comprising: a multiplexer receiving the first, second and third groups of signals, and selecting and outputting one group from the first, second and third groups of signals according to a control signal; a first converting unit converting one of output signals from the multiplexer into a first digital signal for signal processing; a second converting unit converting one of output signals from the multiplexer into a second digital signal for signal processing; wherein when the selected and output group is the first or second group of signals, one of the output group of signals is output to the first converting unit, the other one of the output group of signals is output to the second converting unit; and when the selected and output group is the third group of signals, the CVBS Line-in Video signal is output to the first converting unit; wherein the control signal is sent by a controller unit to control the multiplexer to output one group of the first, second and third groups of signals.
