摘要:
An IEEE 1394 audio/video (AV) network system having a switching structure and a method of forming a network thereof. A method of forming a network in a network system using a digital interface includes checking a power on/off state of a digital interface device in the network, and if the power off state is sensed, transmitting a bus reset command to digital interface devices that form the network and bypassing a connected digital interface bus signal to another digital interface device.

The present invention relates to a double-sided metallic laminate for a printed circuit board and a method for manufacturing the same. The double-sided metallic laminate which comprises a metallic layer at one side, a resin layer of a polyimide for improving adhesion with a metal, a resin layer of a low expansion polyimide having a thermal expansion coefficient of 5×10−6 to 2.5×10−5/° C. and a metallic layer at the other side, has excellent flexibility and thermal resistance, can prevent curl and is securely laminated, particularly without the use of an adhesive. Therefore, it is suitable for a printed circuit board of a small size electric appliance.
