Embodiment
Fig. 2 is the calcspar of the embodiment of data transmission system of the present invention.Data transmission system 1 comprises electronic installation 11 and expander 12.
12 of expanders have first splicing ear 121, second splicing ear 122, the first device extended interface 123 and the second device extended interface 124.The first device extended interface 123 electrically connects first splicing ear 121.The second device extended interface 124 electrically connects second splicing ear 122.Wherein, first splicing ear 121 can be USB (USB) splicing ear or IEEE1394 splicing ear, and second splicing ear 122 can be identical USB (USB) splicing ear or IEEE1394 splicing ear accordingly.The first device extended interface 123 can supply the lower device of transmission band demand to connect.For example, the first device extended interface 123 can be audio input translation interface, audio output translation interface, network switch interface, USB extended interface or IEEE1394 extended interface.The audio input connects translation interface can connect microphone; Audio output translation interface can connect loudspeaker or earphone; The network switch interface can supply grid line to plug connection; The USB extended interface then can be provided with a plurality of usb connecting ports; The IEEE1394 extended interface can be provided with a plurality of IEEE1394 connectivity port; It all can supply storage device, connect like external hard drive or calculating punch, or electronic equipment such as network camera connects use.Second 124 of the extended interfaces of device can supply the higher device of transmission band demand to connect.For example, the second device extended interface 124 can be a display interface connectivity port translation interface, connects for display screen.The second device extended interface 124 can also be the network switch interface, particularly adopts the network switch interface of high transfer rate standards such as 802.11n, 802.11b.
When using this expander 12; And when first splicing ear 121 and second splicing ear 122 inserted the first data transmission port 111c and the second data transmission port 111d respectively; First 123 of the device extended interfaces and the first controller 111a electrically connect; And setting up first data transmission channel, second 124 of the device extended interfaces and the second controller 111b electrically connect, and set up second data transmission channel.Through splicing ear being electrically connected to corresponding data transmission port individually, and device extended interface that can be corresponding and controller foundation data transmission channel independently mutually.
All electrically connect with corresponding electronic installation when the first device extended interface 123 and second installs extended interface 124, as the first device extended interface 123 is plugged external hard drive, the second device extended interface 124 plugs display screen.For example; When the user will play the film information that is stored on the external hard drive; Then see through first data transmission channel film information is reached the first controller 111a; After the processing unit (not shown) that through peripheral controller 111 film information is sent to electronic installation 11 is again deciphered processing, see through second data transmission channel again and be sent to display screen and play.Because first data transmission channel and second data transmission channel can independently operate, thereby can increase the transmission band of overall system, can not feel just when user's ornamental film that therefore picture or audio postpone, play the sensation that has some setbacks.
In addition; First splicing ear 121 of expander 12 and second splicing ear 122 can be provided with in abutting connection with (adjacent) mode or storehouse (stack) mode; Shown in the 2nd figure and the 3rd figure, and the first transmission FPDP 111c and second of electronic installation 11 transmits the set-up mode of also corresponding first splicing ear 121 of FPDP 111d and second splicing ear 122 and is provided with abutment or storehouse mode.When electronic installation has a plurality of first transmission FPDP 111c and the second transmission FPDP 111d; Can avoid causing first splicing ear 121 and second splicing ear 122 all to be connected to same controller and can't to bring into play due effect through the above-mentioned set-up mode person of avoiding the use of wrong plug.In addition; Every group of data transmission port 110 can also different colours or the different printing mode distinguish, and each splicing ear that person easy to use judges expander 12 and data transmission port group 110 be oppositely arranged the position with correct expander 12 and the electronic installation 11 of being connected.
In sum, data transmission system of the present invention can increase transmission band by this through between expander and electronic installation, setting up independently data transmission channel of two frequency bands, and then promotes the data transmission efficiency of expander.
The above only is an illustrative, and nonrestrictive.Anyly do not break away from spirit of the present invention and category, and, all should be contained in the accompanying Claim scope its equivalent modifications of carrying out or change.
