ABSTRACT:
A sample rate conversion device for processing a non-standard television signal converts a sample rate of an output signal component of a color decoder that uses a BL (Burst Locked) clock, which is applied to a memory application part that uses a LL (Line Locked) clock, for a digital television system, such as an IDTV (Improved Definition Television) system, to prevent the degradation of picture quality which may develop when digital processing a non-standard TV signal. The conversion is done by repeating the signal component processed according to the BL clock every time the LL clock is ahead of the BL clock by one clock cycle in the situation when the LL clock is faster than the BL. When the LL clock is slower than the BL clock, the converter skips the signal component processed according to the BL clock every time the LL clock is behind the BL clock by one clock cycle.
