Abstract:
1. A television signal processing devices, comprising: a first signal processing unit, arranged for performing a first signal processing operation upon a television signal according to a feedback signal to reduce distortion of the television signal and accordingly generating a processed television signal; a television demodulator, coupled to the first signal processing unit, the television demodulator arranged for receiving the processed television signal and performing a demodulating operation upon the processed television signal to generate demodulated television signal; and a second signal processing unit, coupled to the first signal processing unit and the television demodulator, the second signal processing unit arranged for receiving the demodulated television signal and performing a second signal processing operation upon the received demodulated television signal to generate the feedback signal to the first signal processing unit; wherein the feedback signal is utilized for indicating a position of a sync tip of each horizontal line in the television signal, the first signal processing operation at least comprises applying a gain to a signal section corresponding to the sync tip in the television signal to change a voltage level of the signal section.
