Video ICs (video integrated circuits) are integrated circuits dedicated to processing video signal capture, encoding, decoding, transmission, enhancement and display driving. Their core functions include image signal processing, video codec (H.264/H.265/AV1), color correction, frame rate conversion, scaling and cropping, and interface conversion. Common types include ISPs (Image Signal Processors), video codecs, display driver ICs, HDMI/DP interface chips and video processors. They are widely used in televisions, monitors, mobile phones, security cameras, projectors, in-vehicle audio-visual systems and video conferencing equipment, serving as the core chips for various video capture and display systems.
