Summary of the invention
Therefore, the TV card that the purpose of this invention is to provide a kind of Express of having Card interface and USB interface.
According to above-mentioned purpose of the present invention, a kind of TV card device is proposed.This TV card device comprises TV card body, Express Card connecting interface and USB connecting interface.Express Card connecting interface is arranged on the TV card body.The USB connecting interface can be arranged on the TV card body or by the usb signal line and be connected with this TV card body.The TV card body can be connected with a computer by Express Card connecting interface or USB connecting interface.
From the above, use TV card of the present invention, allow the user can use Express Card connecting interface or USB connecting interface to be connected with its computer.For product vendor, then can save half research and development, marketing, production and stock's cost.
Description of drawings
For above-mentioned and other purposes of the present invention, feature, advantage and embodiment can be become apparent, preferred embodiment of the present invention is elaborated below in conjunction with accompanying drawing:
Fig. 1 is a kind of TV card schematic diagram according to a preferred embodiment of the present invention;
Fig. 2 is a kind of TV card schematic diagram according to another preferred embodiment of the present invention; And
Fig. 3 is a global concept calcspar of the present invention.
Embodiment
As mentioned above, the invention provides the TV card of a kind of USB of having and Express Card connecting interface, make product vendor can save half research and development, marketing, production and stock's cost.Below will cooperate preferred embodiment to describe this TV card device in detail.
Please refer to Fig. 1, it is a kind of TV card schematic diagram according to a preferred embodiment of the present invention.This TV card is to design with the USB framework basically, but its external mode can be Express Card connecting interface 102 (or being called connector) or USB connecting interface 104 (or being called connector).On TV card body 100, also comprise NTSC/PAL connector 106, so as to being connected with the TV signal cable; And AV terminal connection connected device 108, so as to receiving the signal of audio-visual household electrical appliances.
Please refer to Fig. 2, it is a kind of TV card schematic diagram according to another preferred embodiment of the present invention.This TV card also is to design with the USB framework, but its external mode can be Express Card connecting interface 102 or USB connecting interface 104 (or being called connector).Different with a last preferred embodiment is that USB connecting interface 104 is connected with TV card body 100 by a usb signal line 104a.Also comprise in the TV card body 100 and store groove 112, the USB connecting interface 104 when not using to store.On TV card body 100, also comprise NTSC/PAL connector 106, so as to being connected with the TV signal cable; And AV terminal connection connected device 108, so as to receiving the signal of audio-visual household electrical appliances.
Please refer to Fig. 3, it is a global concept calcspar of the present invention.The electric connection of the solid line presentation-entity of calcspar; Dotted line is then represented separable electric connection (for example the user can or not engage by the joint of connector, controls it and whether electrically connects).USB framework image and sound processing unit 101 is the sound processing of a TV card and the control centre of signal transmission.USB framework image and sound processing unit 101 is connected to audio-visual device in succession 110 and Express Card connecting interface 102 respectively.Audio-visual device in succession 110 can be that above-mentioned NTSC/PAL connector, AV terminal connects connected device or other audio-visual connector, so as to receiving the signal from video-audio signal source 400.Express Card connecting interface 102 can be connected directly to computer end Express Card connecting interface 304.Another kind of mode is to be connected with USB framework image and sound processing unit 101 at TV card body 100 designs one USB connecting interface 104.USB connecting interface 104 just can be connected to computer end USB connecting interface 302.By the function by this TV card, the user just can receive the signal from video-audio signal source 400, and convert the image and sound program that computer can be play to by the Express Card connecting interface 304 or the USB connecting interface 302 of computer end.
By the invention described above preferred embodiment as can be known, use TV card of the present invention, allow the user can use Express Card connecting interface or USB connecting interface to be connected with its computer.For product vendor, then can save half research and development, marketing, production and stock's cost.
Though the present invention discloses as above with a preferred embodiment; yet it is not in order to limit the present invention; any person skilled in the art person without departing from the spirit and scope of the present invention; when the change that can do various equivalences and retouching, so protection scope of the present invention is when looking accompanying being as the criterion that the application's claim scope defined.
