GENERAL DESCRIPTION The TDA9178 is a transparent analog video processor with YUV input and output interfaces. It offers three main functions: luminance vector processing, colour vector processing and spectral processing. Beside these three main functions, there are some additional functions. In the luminance vector processor, the luminance transfer function is controlled in a non-linear way by the...
