Abstract

An embedded household network gateway which supports wireless audio and video transmission is capable of enabling a remote user to be connected to a PC on internet; a close user on PDA can, through the invention, wirelessly and uniformly control electric appliances such as a washing machine and an air conditioner, watch audio and video with large flux and high speed transmitted at real time by film and video entertainment equipments such as a digital television, a DVD, play and store at real time the information recorded by video monitoring aids. The network gateway device comprises an audio and video signal processing module, a core module, a Bluetooth module, and an IEEE802.11g module. The audio and video signal processing module is mainly composed of an audio and video compression and encoding chip, a video A / D decoding chip, and an audio A / D converter. The core module, taking a micro-processor as the center, is connected with the audio and video signal processing module through a bus, with the Bluetooth module through a RS232 interface, and with the IEEE802.11g module through a USB interface, and can be connected to the netting twine of a local area network through a Rj45 tie-in.

Description

technical field [0001] The invention can be used for long-distance and short-distance real-time control and access to various electrical equipment in the home, that is, through this equipment, the remote user can connect to the Internet on the PC, and the short-distance user on the PDA, wirelessly Unified control of electrical equipment (such as washing machines, air conditioners, etc.), watching video entertainment equipment (such as digital TV, DVD, etc.) The device belongs to the technical field of home network gateway devices. Background technique [0002] With the development of computer electronic technology and network technology, and the improvement of people's living standards, the concept of home network came into being. A home network is a network system that provides intelligent services in an all-round way, that is, connects various electrical equipment and electrical subsystems through a certain transmission medium inside the home, realizes resource sharing in...
