The TA1268N integrates chroma signal processing which handles the color information in the video signal. It processes the color burst, color subcarrier, and color difference signals to accurately reproduce the colors in the video image. Luminance signal processing is responsible for handling the brightness information in the video signal. It processes the luminance signal to provide the appropriate contrast and brightness levels in the image. It also incorporates synchronization signal processing to generate the necessary timing signals for the video signal. These signals are used to synchronize the horizontal and vertical scanning of the video display.

Automatic Gain Control (AGC) ensures that the signal level is maintained at a consistent level, even when the input signal strength varies. This helps to prevent distortion and ensures a clear and stable picture. Automatic Frequency Control (AFC) keeps the frequency of the local oscillator locked to the frequency of the incoming video signal, ensuring that the video signal is properly synchronized. The TA1268N also incorporates deflection processing, which generates the signals necessary to control the horizontal and vertical deflection of the electron beam in the CRT (Cathode Ray Tube) display.
