Video and audio network distribution system

摘要

This disclosures describes a local area network (LAN) video and audio system 20. The disclosed system 20 includes a networked audio source node device 300 that couples to a plurality of network speaker nodes 100 via a TCP/IP LAN network 200 where the networked audio source node device is a video device. Additionally, the system includes an internet interface 400 and a network control server 310 that couple to the network speaker nodes 100 via said LAN network 200. Finally, the system 20 includes a legacy converter and controller 600 that couples to the LAN network 200 and further couples a legacy source 500 to the LAN network 200.

1. A video and audio system that uses a TCP/IP LAN (local area network) using TCP/IP as the communication protocol, comprising:
a networked audio source node device that further comprises a video device; a plurality of network speaker nodes, said network speaker nodes couple to said networked audio source node device via a TCP/IP LAN using TCP/IP as the communication protocol; an internet interface coupled to said network speaker nodes via said TCP/IP LAN using TCP/IP as the communication protocol; a network control server coupled to said network speaker nodes via said TCP/IP LAN using TCP/IP as the communication protocol; and a legacy converter and controller coupled to said TCP/IP LAN using TCP/IP as the communication protocol that couples a legacy source to said TCP/IP LAN, said legacy converter and controller further comprise an embedded controller with memory and which is programmed to function as a web server that uses TCP/IP as the communication protocol; wherein said network speaker nodes further comprise:
an embedded controller with memory and which is programmed to function as a web server that uses TCP/IP as the communication protocol;a pre-amplifier that couples to a digital signal processor and adjusts and filters the analog audio signal and an amplifier that couples to said pre-amplifier and amplifies the analog audio signal, said pre-amplifier further comprises an electronic crossover for frequency division;speaker sensors that include a microphone used for receiving and or gathering control information that enables internal auto adjustment by frequency separation to enhance speaker protection and performance from said network speaker nodes surroundings, said control information is sent to other devices on said TCP/IP LAN; anda speaker/microphone driver that couples to said amplifier and provides the external connection to the speaker/microphone components for the analog audio signal.
