The audio processing components may include an AC97 interface and CODEC or an audio controller that processes PCI Express information. The audiovisual output signal may include a variety of combined or separate audiovisual appliance compatible outputs such as coaxial cable output, EVC output, HDMI output, HDTV output or 1394 output.Other References
