Abstract
A scanning line converting system comprises down-converters arranged in parallel for converting an input high definition television signal to a current television signal, and double-frequency converting sections for respectively doubling the frequency of the down-converted current television signals, for synthesizing them, and for delivering the synthesized signal as a non-interlaced video signal. The non-interlaced video signal can be obtained by properly controlling a vertical filter which is a part of the down-converter with no additional interlace/non-interlace converting unit.
