The video signal-processing circuits required to implement an LCD TV set can be easily formed by combining this IC with a digital decoder, a microcontroller, and an LCD panel. Since this IC does not require an external frame memory for resolution conversion, it can contribute to minimizing total costs. As additional functionality, it also provides inputs for personal computer video (up to XGA) and digital TV (480p/480i).
