Problems solved by technology

[0004] However, most of the general multimedia cards or storage cards with USB interfaces only have one interface, for example, multimedia cards only have an MMC interface, and smart sticks with USB interfaces only have a USB interface, although they can still be used in portable Digital images or MP3 audio signals are transmitted in electronic devices, but it is a pity to transmit MP3 audio signals with low data volume at high speed of USB interface, but consume high power; or use MMC interface at a lower speed Sending video signals with a large amount of data, although it saves power, the transmission speed is slower

Embodiment Construction

[0020] Please refer to FIG. 1 , which shows a combined diagram of the multimedia storage device of the present invention. As shown in the figure, the multimedia storage device 1 of the present invention includes: a printed circuit board 10 ; a controller 20 ; a storage medium 30 and a casing 40 .

[0021] Wherein, the printed circuit board 10 is used to present components such as the controller 20 and the storage medium 30, and one end 11 of the printed circuit board 10 is exposed to the housing 40, so that the exposed portion 11 can be inserted into a connector 50 of a host system . And the exposed part 11 has a set of terminals 12, so that when plugged into the connector 50 of the host system, the set of terminals 12 can be connected with the terminals in the connector 50 of the host system, wherein the set of terminals 12 Used to support the Smart Stick Interface (ISI), which includes ten terminals, namely V Power , GND, D0, D1, D2, D3, D4, D5, CMD and CLK. Among them, {...

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...
