Abstract:
A device for decoding a television video signal, the device comprising:a tint controller for converting a plurality of color space converting coefficients which are used for converting a color space signal into R, G, B signals into tint considered coefficients for tint control by using a sine theta value and a cosine theta value, both of which are variables, wherein the tint controller comprises: a first multiplexer and a second multiplexer each for receiving a first to a ninth color space converting coefficients in parallel: a third multiplexer for receiving the first variable sine theta value and the first selection signal in parallel; a fourth multiplexer for receiving the second variable cosine theta value and the second selection signal in parallel; a first multiplier for multiplying outputs of the first multiplexer and the third multiplexer; a second multiplier for multiplying outputs of the second multiplexer and the fourth multiplexer; and, an operator for carrying out an operation in which outputs of the first multiplier and the second multiplier are summed at one side and the outputs of the first multiplier and the second multiplier are subtracted at the other side; and, a color space converter for producing the R, G, B signals displayable on a monitor by using the tint considered coefficients from the tint controller and the color space signals.
