Abstract
A TV receiver with selectable signal processing systems in which main controller 103 selects a proper signal processing system according to signal processing unit 120 based on the results of monitoring the type and the number of the input signals by input signal monitor 102 and the monitor result for user's request by signal display monitor 123. Main controller 103 downloads the instruction program from program memory 104, and then transfers the instruction program to signal processing unit 120. Accordingly, signal processing unit 120 performs one unit of the three-dimensional Y/C separation, two units of the two-dimensional Y/C separations or three units of the one-dimensional Y/C separation on the NTSC video signal.
