Abstract
A system for coding a composite color television signal and a system for decoding the received coded composite color television signal are disclosed. Coding is achieved by the use of a sampling frequency lower than the Nyquist sampling frequency to provide a direct-coding system in which the composite television signal is sampled at a timing where the subcarriers stand at phases about 180.degree. away from each other in each scanning line and at a timing where the subcarriers stand at phases about 90.degree. away from each other between adjacent scanning lines. In the decoding system, an interspatial signal component lying at a midpoint between every two sampling points is produced from the sampled signals. A composite television signal is produced from the sample signal and the interspatial signal.
