Description
The present invention relates to a connection device for a smart TV that selectively uses HDMI and MHL, and more specifically, to connect a general digital TV to the Internet through a WIFI module to use as a smart TV, HDMI installed in the digital TV The present invention relates to a smart TV connection device that selectively uses HDMI and MHL, which are universally available, having a connector that can be connected to both a port or an MHL port.
Smart TV is connected to the Internet network and receives various information through the communication network established by the Internet Service Provider (ISP), and functions as a computer such as games, video-on-demand, and mobile applications. Say TV possible.
In general, in order to construct a smart TV system, a wired / wireless connection module for enabling Internet access must be installed in a general digital TV, and a data processor must be provided to convert data into an Internet protocol.
However, most of the recently released smart TVs do not have internet access functions, so they can be used as smart TVs only when an external device such as a set-top box (STB) is connected to the digital TV.
1 is a conceptual diagram illustrating a digital content control system according to the related art, and illustrates a method of connecting to an internet network using a set-
Referring to FIG. 1, a conventional system basically includes an
The MDD 110 refers to a general display device (eg, a TV receiver) displaying a broadcast image provided from the STB 100. Therefore, the HD-class image can be received and displayed through the
The STB 100 performs various signal processing through communication with the
In addition, by transmitting the image displayed in the MDD (110) to the SDD (120), it is possible to provide and control the screen through a separate device. The image provided to the SDD 120 is reproduced in the same manner in the
In addition, the
In addition, the STB 100 has an Internet communication means, and various servers (eg, the ISO
ISO 130 is an Internet service operator and provides an internet communication service with each server.
The user may execute the Internet content provided by the ISO 130 in the MDD 110 through the Internet network. In addition, the user may receive and watch a terrestrial broadcast or cable broadcast signal.
In the smart TV content providing system according to the related art, the broadcast signal and the Internet access signal are transmitted only to the HDMI port of the TV. Recently, due to the widespread use of mobile terminals, TVs using MHL (Mobile High-Definition Link) ports in addition to high-definition multimedia interface (HDMI) ports, which are used as interfaces of ordinary video devices (DVD players, etc.), have become popular. In the case of a TV with only the MHL port, it is difficult to use a smart TV because it cannot connect a conventional set-top box.
The present invention for solving the above problems is provided with two connectors to be connected to both the HDMI port and the MHL port, and provides an Internet connection function to the digital TV through a variety of interfaces by selectively using any one of them It is an object of the present invention to provide a smart TV connection device that selectively uses HDMI and MHL.
In addition, the present invention, when supplying the DC power to the connector connected to the port of the TV, when connecting the main body of the connector and the connector, the terminal for the grounding of the power than the terminal for supplying the video signal and power contact the moment It is an object of the present invention to provide a connection device for a smart TV that selectively uses HDMI and MHL, which can prevent damage to a circuit caused by a transient supply of transient current.
The present invention has been made in order to solve the above-mentioned problem is a device for connecting the

According to the present invention, even if only one port of the HDMI port and the MHL port is installed on the user's digital TV, the user can freely connect the connection device to use his digital TV as a smart TV.
In addition, according to the present invention, even if the instantaneous transient current is included in the DC power supply to the connection device is bypassed through the ground terminal, there is an effect that the components inside the connection device is not damaged.
