Abstract

The invention relates to a medium design mode of a multimedia data transmission, which can be used as the working medium of the data storage and communication apparatus. It also discloses a multimedia data storage which can embed into a computer or around the apparatus so as to transmit the data. The multimedia storage apparatus comprises: a printing circuit plate used to load the units with one end of the multimedia storage apparatus possessing a group of ends which can provide a differential signals and a level transmitting signals of the synchronic time pulse to provide the working medium which is connected with the out device; a controller positioned on the printing circuit and connected with the ends which switches the end signal connecting condition to control the transmitting speed and the power consuming of the multimedia storage; and a storage media positioned on the printing circuit and connected with the ends which is used to store the data.

Description

technical field [0001] The present invention relates to a multimedia data storage and communication device and its judging method, especially to a device that can switch the multimedia device to work in an appropriate signal interface mode according to the control signal sent by the system, so as to control the transmission of the multimedia device speed and power consumption. Background technique [0002] Press, there are many interfaces between a general small memory card and a host or a portable electronic device, such as CFC (Compact Flash Card) or SD (Secure Digital Card) / MMC (Muiti-Media Card), etc. are two of the more common interface. However, the newly developed USB interface memory card has the advantage of high-speed transmission, such as the American Intel  The ExpressCard developed by the company and the PQI developed by the Chinese  Self-developed Intelligent Stick system. The traditional smart stick is actually a memory card with a USB interface, and the...
