Method and circuit for time-correction of digital switching signals |
摘要 |
A time correction value for each digital switching signal is determined and a set of switching control signals is formed which produce a progressive switching of the digital signal as a function of the time correction value. Each time correction value is stored until the following digital switching signal. The method improves chroma keying in digital color television systems.
