The AVerMedia 61051 MPEG Encoder is a hardware component used in some of AVerMedia's video capture and TV tuner cards. It is designed to offload the video encoding process from the CPU, compressing video into the MPEG format (typically MPEG-2 or MPEG-4), which allows for better performance and reduced CPU load during video recording or streaming. This chip is commonly found in devices that capture TV signals, video game footage, or analog video sources.

The Windows driver for the AVerMedia 61051 MPEG Encoder allows your computer to properly interface with the device, ensuring that your operating system can detect and use the hardware for video capture and encoding.
