Abstract
This disclosure describes an intelligent network communication device in an audio video distribution system that uses a local area network that includes a network speaker node; an audio input device that receives the analog audio signal and that couples to a network speaker node through a speaker/microphone driver; and an audio output device that transmits the analog audio signal and that couples to the network speaker node through the speaker/microphone driver. The network speaker node further includes a controller with a network interface that couples to the local area network, where the controller further comprises an embedded controller with memory and which is programmed to function as a web server. The network speaker node further includes a digital signal processor that couples to the controller. And, the network speaker node further includes a speaker/microphone driver that couples to the digital signal processor.
