The AVerMedia Hardware MPEG TVTuner Windows Driver is a software component that allows your Windows computer to interact with AVerMedia TV tuner cards or devices that have hardware MPEG encoding capabilities. These hardware MPEG TV tuners are designed to decode TV signals and encode video in the MPEG format (such as MPEG-2 or MPEG-4), which is more efficient for playback, recording, and streaming. By using this driver, your PC can access and control the TV tuner, allowing you to watch and record TV broadcasts through compatible software.
