  • Patent number: 7562169
    Abstract: A Video and Audio Front End Assembly and Method. The device and method of this invention takes advantage of the hardware improvements available in personal computing machines that enable higher speed bus communications and much greater computational capacity. The system converts many of the processes needed to convert analog video and audio inputs so that they are displayable by a personal computer from a hardware integrated circuit to a set of software routines. The system combines a simplified hardware front-end interface between the computer and the analog input signals and a very flexible set of software applications running on the host computer. The hardware front end employs an integrated circuit device that is much lower in complexity and cost than the conventional audio/video decoder integrated circuit.
