Working Principle

The TDA19998HL/C1,518 integrates a set of powerful signal processing functions. Firstly, the primary analog signals, such as the TV signal, are captured and digitally filtered to obtain digital signal information. Then the signal parameters, such as brightness, contrast, color saturation and hue, are adjusted by the digital filter, in order to compensate for the signal distortion and get the best picture quality. After that, the picture is converted to digital format, compressed and ready for digital output.

At the same time, the IC enables the video output to be more stable and clear at different resolutions, which is essential for video applications in various industries. Furthermore, the picture processing is performed by the built-in digital signal processor DSP, which enables digital signal processing, analysis and generation in real time, ensuring accurate output results and low latency.

In addition, the IC is equipped with built-in analog-to-digital converters, as well as synchronous detection functions, which help to accurately capture and process the input analog signal parameters. It is also designed with several programmable filters, which can be tuned to enable better filtering of incoming signals, achieving better picture and audio quality.
