ABSTRACT OF THE DISCLOSURE A television signal processor which is compatible with the existing television systems and is capable of producing television signals having a larger aspect ratio than the standard aspect ratio has an arrangement such that, at the transmission side, a main signal and a multiplex signal are produced from an electrical signal obtained by receiving an original image through processes such as time-axis compression, time-axis expansion, and chrominance signal processing, and are subjected to non-time-axis multiplexing. The processor has a further arrangement such that, at the reception side, there are provided a circuit for separating the non-time-axis multiplexed signal, a circuit for separating a luminance signal and a chrominance signal, a circuit for demodulating the chrominance signal, a circuit for effecting time-axis compression, a circuit for time-axis expanding the time-axis multiplexed signal, and a circuit for time-axis compressing the non-time-axis multiplexed signal. A receiver provided with this processor may receive images broadcast under the existing television systems without troubles and also may reproduce TV images with a larger aspect ratio than the conventional 4:3 aspect ratio by the application of synchronous detection, time-axis compression, time-axis expantion, etc.
