Description
Technical field
The present invention is about a kind of TV card, and particularly relevant for a kind of TV card with Express Card interface and USB interface.
Background technology
By computer TV programme, it has been the application that a lot of computer users are general.As long as computer installs a TV card additional, from wired or wireless TV programme signal, just can be converted into the form that computer can be play, make to allow computer user without separately purchasing just energy TV reception of a television set.
Present computer transmission interface is a feast for the eyes, makes the interface of TV card also present same situation, for example, have the TV card of USB, Express Card interface.For product vendor, just need to release different product line, bear marketing, research and development, production and the stock's of different product cost.Or need to use in addition detachable interface adapter, and it has two kinds of interfaces that meet respectively TV card and computer, during use, one end of interface adapter is connected with the interface of TV card, and the other end is connected with the interface of computer.
Summary of the invention
Therefore the TV card that, the object 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 TV card body.USB connecting interface can be arranged on TV card body or by usb signal line and be connected with this TV card body.TV card body can be connected with a computer by Express Card connecting interface or USB connecting interface.
From the above, apply TV card of the present invention, allow user can use Express Card connecting interface or USB connecting interface to be connected with its computer.For product vendor, can save half research and development, marketing, production and stock's cost.
Accompanying drawing explanation
For above and other object of the present invention, feature, advantage and embodiment can be become apparent, below in conjunction with accompanying drawing, preferred embodiment of the present invention is elaborated:
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 global concept calcspar of the present invention.
Embodiment
As mentioned above, the TV card ，Shi product vendor that the invention provides a kind of USB of having and Express Card connecting interface can save half research and development, marketing, production and stock's cost.Below will coordinate 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 USB framework substantially, 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 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 is also to design with USB framework, but its external mode can be Express Card connecting interface 102 or USB connecting interface 104 (or being called connector).Different from a upper preferred embodiment, USB connecting interface 104 is connected with TV card body 100 by a usb signal line 104a.In TV card body 100, also comprise and store groove 112, the USB connecting interface 104 while not using to store.On TV card body 100, also comprise NTSC/PAL connector 106, so as to being connected with 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 global concept calcspar of the present invention.The electric connection of the solid line presentation-entity of calcspar; Dotted line represents separable electric connection (for example user can or not engage by the joint of connector, controls it and whether is electrically connected).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 respectively audio-visual device in succession 110 and Express Card connecting interface 102.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 AV 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 design one USB connecting interfaces 104.USB connecting interface 104 just can be connected to computer end USB connecting interface 302.By the function by this TV card, user just can, by Express Card connecting interface 304 or the USB connecting interface 302 of computer end, receive the signal from AV signal source 400, and convert the image and sound program that computer can be play to.
From the invention described above preferred embodiment, apply TV card of the present invention, allow user can use Express Card connecting interface or USB connecting interface to be connected with its computer.For product vendor, can save half research and development, marketing, production and stock's cost.
Although 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 doing various equivalent change and retouching, so protection scope of the present invention is when being as the criterion of defining depending on accompanying the application's claim scope.
