  • Television apparatus with automatic selection and processing of video input signals of composite and non-composite form
    Patent number: 5253044
    Abstract: A television system comprises a first input terminal (20) for providing a composite video (CSCC) signal or a separated luminance (SCC) signal, and a second input terminal (15) for providing a separated chrominance (C) signal. A change-over switch (11) has a first input (a) coupled to the first input terminal (20) through a path including a color sub-carrier filter (9), a second input (b) coupled to the second input terminal (15) through a path not including the color sub-carrier filter (9), and an output (c) coupled to the input (d) of a color decoder (8). The change-over switch couples the input (d) of the color decoder (8) to the first input terminal (20) in a first position (a), and couples the input (d) of the color decoder (8) to the second input terminal (15) in a second position (b). A sub-carrier detector (CK) is coupled to the output (c) of the change-over switch (11) for detecting the presence or absence of a color sub-carrier.
