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...
