In this case, when the signal is input to either the HDMI connection unit 210 or the DVI connection unit 220, the signal control unit 240 may transmit an input signal to the signal conversion unit 250, When a signal is input to both the HDMI connection unit 210 and the DVI connection unit 220, the signal conversion unit 250 transmits a signal with a later time point at which the signal is connected.
In the following, the signal conversion apparatus 200 according to an embodiment of the present invention is divided into parts and examined in detail.
First, the HDMI connection unit 210 and the DVI connection unit 220 are searched. The HDMI connection unit 210 and the DVI connection unit 220 receive the HDMI signal and the DVI signal, respectively, and transmit the HDMI signal and the DVI signal to the signal transmission unit 230.
The HDMI connection unit 210 and the DVI connection unit 220 include an HDMI connector and a DVI connector, respectively, and may be connected to an external device via an HDMI cable and a DVI cable. However, the present invention is not limited to this, and the signal conversion apparatus 200 according to an embodiment of the present invention may be built in a specific device and receive an HDMI signal or a DVI signal directly from another module, And may be connected to a substrate or a module.
In a case where the signal conversion apparatus 200 according to one embodiment of the present invention is configured as one independent apparatus, the HDMI connection unit 210 and the DVI connection unit 220 may include an HDMI connector and a DVI connector, respectively, , It is possible to conveniently connect and operate using an HDMI cable and a DVI cable conforming to the standard specifications.
Next, the signal transmitting unit 230 transmits the HDMI signal or DVI signal received from the HDMI connection unit 210 and the DVI connection unit 220 to the signal conversion unit 250. At this time, the signal controller 240 determines which of the HDMI signal and the DVI signal is to be transmitted to the signal converter 250 by the signal transmitter 230. Accordingly, the signal transmitter 230 receives a part or all of signals including signals necessary for converting the HDMI signal and the DVI signal into the display port signal under the control of the signal controller 240, 250, respectively.
For example, the signal conversion unit 240 may convert the number of signals input from the HDMI connection unit 210 and the DVI connection unit 220 and the number of signals output to the signal conversion unit 250 into one or two And may include the above-described switches swtich. The switch can be used as a switch circuit or a switch element capable of transmitting a signal without distortion in consideration of a waveform and a data rate of an HDMI signal and a DVI signal.
The signal control unit 240 detects whether a signal is input from the HDMI connection unit 210 and the DVI connection unit 220 and outputs a signal to either the HDMI connection unit 210 or the DVI connection unit 220, Determines whether to transmit the signal to the signal converting unit 250, and controls the signal transmitting unit 230 accordingly.
The signal controller 240 determines whether a power signal of the connection unit 210 and the DVI connection unit 220 is input to the HDMI connection unit 210 and the DVI connection unit 220, And it is possible to detect whether each signal is inputted or not.
For example, when the HDMI connector is used as the HDMI connector 210, since the pin 18 of the HDMI connector is assigned to the + 5V power input line, it is determined whether the + 5V power is input to the pin 18 It is possible to judge whether a cable is connected to the HDMI connector. Similarly, when the DVI connector is used as the DVI connector 220, since the pin 14 of the DVI connector is also assigned to the + 5V power input line, as described above, whether the + 5V power is input to the pin 14 It is possible to judge whether a cable is connected to the DVI connector.
At this time, it is not always necessary to determine whether each signal is input based on whether the HDMI connector and the DVI connector are powered or not, and it is also possible to determine whether each signal is input by sensing another HDMI / DVI signal. For example, the HDMI / DVI data signal input to the HDMI connection unit 210 and the DVI connection unit 220 may be sensed to determine whether each HDMI signal and DVI signal is input.
The signal controller 240 controls the signal converter 250 to transmit a signal to the HDMI connector 210 or the DVI connector 220 when the signal is input to the HDMI connector 210 or the DVI connector 220, When a signal is input to both the connection unit 210 and the DVI connection unit 220, the signal conversion unit 250 may transmit a signal with a later signal connection point.
The signal control unit 240 verifies whether the signals input to the HDMI connection unit 210 and the DVI connection unit 220 are HDMI / DVI signals and transmits the signals to the HDMI connection unit 210 and the DVI connection unit 220, DVI signals that are input to the signal conversion unit 250. The signal conversion unit 250 may receive the HDMI / DVI signals.
For example, when an HDMI signal is input to the HDMI connection unit 210 and a wrong signal other than the DVI standard is input to the DVI connection unit 220 (for example, an appropriate DVI signal The signal input to the signal conversion unit 250 can be continuously maintained as an HDMI signal by adding a verification process of a signal input to the DVI connection unit 220. [ Accordingly, it is possible to prevent an erroneous signal from being input to the signal converting unit 250 by simply adding a verification process, not merely inputting a signal.
The signal controller 240 determines which signal is to be transmitted to the signal converter 250 considering the result of sensing the signal input to the HDMI connector 210 and the DVI connector 220, And controls the signal transfer unit 230 accordingly.
Next, the signal converting unit 250 converts the HDMI signal or DVI signal received from the signal transmitting unit 230 into a display port signal and outputs the signal. The HDMI signal, the DVI signal, and the display port signal can all be generated and converted in accordance with a standard standard, so that they will not be discussed in detail here.
In this case, even if a signal transmitted to the signal converter 250 of the signals input to the HDMI connection unit 210 and the DVI connection unit 220 is changed, the signal converter 250 And a signal storage unit (not shown) for buffering the pre-change input signal or the output signal thereof so as to prevent the output signal from being cut off.
For example, when an HDMI signal is input and converted into a display port signal and a DVI signal is being supplied to a user as an image, the signal transmission unit 230 transmits a signal input to the signal conversion unit 250 DVI signal. At this time, it takes a certain time to convert a newly input DVI signal into a display port signal, decode the converted display port signal again and provide it to the user as an image, etc., and the user feels the inconvenience Therefore, the signal storage unit may be configured using a flash memory or the like so that the HDMI signal is stored or a signal obtained by converting the HDMI signal into the display port signal is stored.
The display port signal converted by the signal converter 250 may be output through a display port connector 260 such as a display port connector or directly connected to a display port device to be provided to the user .
Further, the signal conversion apparatus 200 according to an exemplary embodiment of the present invention may include a power supply pin (for example, pin 18 of the HDMI connector) of the HDMI connection unit 210 such as the HDMI connector or the DVI connection unit 220 such as the DVI connector, Lt; / RTI > pin of the DVI connector). In this case, the signal conversion apparatus 200 according to the embodiment of the present invention can be miniaturized, and the manufacturing process can be simplified, and further, the cost of the product can be reduced.
If necessary, power may be supplied from an external source through a mini-USB connector or the like to an AC to DC adapter to drive the signal conversion apparatus 200 according to an embodiment of the present invention. And a selection device may be added to allow the user to select and use the power source.
In this way, it can be implemented in various forms such as a notebook, a display device, and the like, which is applied to a product having a large space constraint.
Furthermore, the signal conversion apparatus 200 according to an exemplary embodiment of the present invention may include a reset function for responding to the instability of the signal conversion unit 250, which may occur according to the switching of the input signal. For example, when the signal input to the signal conversion apparatus 200 is changed from the HDMI signal to the DVI signal, there is a possibility that the signal is changed to the DVI signal and the signal conversion unit 250 may malfunction A signal conversion unit 200 that is reset when a signal input to the signal conversion apparatus 200 is changed to a DVI signal and then the signal conversion apparatus 200 is reset, 250). ≪ / RTI >
In addition, the signal controller 240 determines whether the display port signal output from the signal converter 250 is an appropriate signal according to the standard, and if necessary, initializes the signal converter 200 ) So as to be driven again. In addition, the signal conversion apparatus 200 may be configured to include a reset switch (not shown) or the like so that the user can directly reset the signal conversion apparatus 200 and restart it.
FIG. 3 illustrates a flowchart of a signal conversion method according to an embodiment of the present invention. As shown in FIG. 3, the signal conversion method according to an exemplary embodiment of the present invention includes the steps of (a) detecting which of the HDMI signal and the DVI signal is input (S310), (b) In the case where either of the HDMI signal and the DVI signal is input, it is determined to convert the input signal into the display port signal.
