Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1, a display source apparatus 100 according to an exemplary embodiment of the present invention includes a wireless connection unit 110, an application control unit 120, storage units 132 and 134, a power input interface 140, a PMIC (Power management IC, Power Management IC, 145), an A / V interface 150, and a dual power input unit 160. [ However, it is needless to say that the present invention can also be implemented as a display source device including only a part of the above components or including more components than the above components.

Here, the 'display source device' refers to an external display device (a device having a screen capable of displaying images such as a TV, a monitor, another computer, or a mobile device) through an A / V interface provided in the device, , Web pages, and various application execution results, and so on. That is, in the embodiment of the present invention, the display source device stores (i.e., temporarily saves or temporarily stores) contents such as image contents, executes the contents, and transmits the video data and / (I. E., It becomes an A / V implementation medium). Therefore, the above-mentioned display source device may be a device having a screen capable of displaying images and the like on its own.

In the present specification, however, the above display source device is a product having no own screen and transmits content data such as various application execution screens executed in the device to an external display device to be connected thereto, And a case for allowing display through a screen of the apparatus will be mainly described. That is, it is assumed that the display source device is a product of the HDMI Dongle type (a portable device having no own screen) as shown in FIG. Of course, the category of the display source apparatus according to the present invention may be varied as described above.

1, the wireless connection unit 110 is a part for implementing connectivity with an external device and includes a wireless Internet module (not shown) such as WLAN and WiFi, a short-range wireless communication module Not shown), and the like. The display source device 100 of FIG. 1 does not have a configuration (for example, a USB interface) capable of performing wire data communication with an external device, so that the display source device 100 can communicate with an external device via the wireless connection unit 110 Data communication is performed. For example, data communication between both devices can be made through the Bluetooth pairing between the display source device 100 and the external display device. Also, the display source apparatus 100 can access various contents stored in the web server through communication with an external web server through a WLAN or the like. At this time, the video / audio data acquired through such an approach may be displayed on the screen of the external display device by being transmitted to the external display device.

The application control unit 120 executes various contents stored in the storage units 132 and 134 or contents received from an external web server or the like by including an Application Process and transmits the video / To the external display device through the interface 150.

In the embodiment of the present invention, the connection between the display source apparatus 100 and the external display apparatus (not shown) (i.e., the establishment of the video / audio data transmission path between the two apparatuses) is performed in the docking cradle 200) is used as a medium. Of course, the present invention does not exclude a direct connection method or a connection method via a cable as a connection method between the display source apparatus 100 and the external display apparatus. In the following description, for the sake of conciseness of the description, a description will be given of a case in which the display source apparatus 100 and the external display apparatus 100 are connected to each other via the docking cradle 200 having the configuration as shown in the block diagram of FIG. 5, The case where the connection is made will be mainly described.

An A / V interface (Audio / Video Interface) 150 of the display source apparatus 100 is an interface for external output of audio or / and video data. Here, it is assumed that the A / V interface 150 is HDMI (High-Definition Multimedia Interface). Of course, it is obvious that various video / audio input / output interfaces can be utilized.

The display source device 100 may be docked through physical coupling between its A / V interface 150 and the first A / V interface 210 of the docking cradle 200. 6, the A / V interface 150 is formed on the bottom surface of the stick-shaped display source device 100, and the first A / V interface 210 is formed in a shape of a cradle And may be formed on the bottom surface of the predetermined insertion space 202 of the docking cradle 200. Thus, by physically inserting the display source device 100 into the insertion space 202 formed in the docking cradle 200, a physical coupling between the A / V interfaces 150 and 210 of both devices can be achieved.

And a second A / V interface 220 is separately provided in the docking cradle 200. The second A / V interface 220 is responsible for the connection with an external display device in which the content is actually displayed. After the docking connection between the display source device 100 and the docking cradle 200 described above, Video / audio data transmitted from the source apparatus 100 can be transmitted to an external display apparatus through the path of the first A / V interface 210, the second A / V interface 200, and the external display apparatus do.

Also, according to the embodiment of the present invention, the power supply path to the display source apparatus 100 can be determined as follows depending on whether a docking connection is established or not. In other words, in a docking-unconnected state in which no docking connection with the docking cradle 200 is made (more precisely, when power is not supplied through a reserved pin of the HDMI as described later) A power supply path through which the power supplied through the power input interface 140 provided in the display source apparatus 100 itself is used as the power of the corresponding apparatus 100 through the dual power input unit 160 may be formed. This is shown in FIG.

That is, the display source device 100 according to the embodiment of the present invention may have a separate power input interface in the device itself and may be connected to an external display device directly or through a separate cable without the docking cradle 200 It is also guaranteed to be portable. According to this, even if the docking cradle 200 is not carried together, direct power input is possible, and the display source device can be freely used while being carried around.

It should be noted that the dual power input unit 160 and the reserved pin of the HDMI connector are still connected to each other by a dotted line in FIG. In this case, there is no problem in operation even when a universal HDMI cable is connected to the HDMI output, and it can be prevented from affecting the external display device. This can be achieved by implementing a connection portion between the dual power input unit 160 and the reserved pin by applying a Schottky diode.

Hereinafter, the reserved pin of the HDMI will be briefly described as follows. As to the pin configuration of HDMI, it has common reserved pins as shown in Tables 1 to 3 below.

[Table 1 - HDMI type A]

[Table 2 - HDMI type B]

[Table 3 - HDMI type C]

This reserved pin is a pin for additional function of HDMI 1.4, which does not use up to HDMI 1.3c and is not required to be used in the scenario of using HDMI Dongle product. Accordingly, in the embodiment of the present invention, when the display source device 100 is docked with the docking cradle 200 by using the reserved pin as a power supply pin, the display source device 100 can receive the docking cradle 200 At the same time as the power is supplied, the multimedia transmission of the original purpose of HDMI becomes possible.

That is, as described above, when the docking connection is made between the display source device 100 and the docking cradle 200 (that is, when power is supplied through the HDMI reserved pin), the power input interface 140 A power supply path may be formed so that the power supplied through the power input interface 230 of the docking cradle 200 is used as the power source of the display source device 100 via the HDMI reserved pin. The drawings relating thereto are shown in Figs. 2 and 3. 2, it is assumed that there is no power input through the power input interface 140 of the display source apparatus 100. [ The power supply path at this time is formed in the direction of the power input interface 230, the HDMI reserved pin, and the PMIC 145 of the docking cradle 200.

Therefore, according to the embodiment of the present invention as described above, it is expected that the present invention can solve the inconvenience that current consumers feel while maintaining the advantage of being portable easily when using a display source device such as HDMI Dongle. Furthermore, in case of other products which have A / V output function such as HDMI and not limited to HDMI Dongle, the power input method described above can enhance the design and usability of the product.

Although the above description is based on a structure using a docking cradle, a cable assembly instead of a cradle can be used alternatively. That is, a separate cable may be used to supply power to the reserved pin of the existing HDMI cable. 6, the display source device is an HDMI Dongle in the form of a stick or a bar, and the docking cradle is illustrated as having a cradle shape having an insertion space into which the upper display source device can be inserted, But may also be embodied in various other forms and forms.

In the above description, the case where HDMI is used as the A / V interface has been mainly described, but it goes without saying that various video / audio input / output interfaces may be utilized. In the case of the display source apparatus 100 of FIG. 1, the case of data communication through the wireless connection unit 110 is described. However, it is needless to say that a wired interface (USB interface, etc.) for data communication may be further provided. For example, if MHL (Mobile HD Link) is alternatively utilized as a video / audio input / output interface, the data communication itself can be performed in a wired manner via the interface. In doing so, the power supply to the docking cradle -> display source device will be made by the MLH's inherent function. In such a case, in some cases, an HDMI-MHL converter or a separate connector having such a function may be required for interface compatibility between docking-connected devices. Or the HDMI-MHL converter may be added to the docking cradle if the first A / V interface 210 of the docking cradle is MHL and the second A / V interface 220 is HDMI.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the following claims .
