Sliding type portable device for using visual equipment having HDMI connector slot as smart equipment}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peripheral device of a video device capable of connecting to the Internet. In particular, the present invention relates to a high definition multimedia interface (HDMI) for transmitting a digital video signal and a digital audio signal in a single digital interface having a bandwidth of 5 Gbps or more. It provides an application device that can be used as a smart device based on Android (Android ICS (4.0)), and at the same time adopts the structure of a conventional USB portable device for easy portability. A sliding type portable device for using a video device having an HDMI connector slot as a smart device.

Recently, IPTV service is widely used, which is a service that provides information service, video contents, and broadcasting through TV using high-speed Internet, and is a type of digital convergence in that it is a convergence of the Internet and TV. . The difference with conventional Internet TV is that it uses a TV instead of a computer monitor and a remote control instead of a mouse.

To use such an IPTV, only a TV, a set-top box (STB), and an Internet line need to be connected. In other words, you only need to connect an STB or a dedicated modem to the TV, and turn on the power as if you were turning on the TV. Therefore, even a user who is not familiar with a computer can use the remote control to provide services such as watching an internet, watching a movie, home shopping, home banking, and online games.

IPTV is not different from general cable broadcasting or satellite broadcasting in that it provides broadcasting contents including video, but it has great features in that it adds bidirectionality. Unlike general public broadcasting, cable broadcasting or satellite broadcasting, viewers can watch only the programs they want to watch at their convenience.

By the way, although IPTV is bidirectional, it is still true that the limitation is still present. For example, a broadcast program has a re-broadcasting function so that it can be viewed at a desired time, but content related to the program (for example, program background, character introduction, etc.) cannot be provided. You will need to access a separate web site to obtain relevant information.

In addition, with the spread of digital home appliances such as digital TVs, LCD monitors, PDPs, and the like, digital interfaces capable of digital data communication with peripheral devices such as IEEE 1394 and USB have been widely adopted.

In particular, a digital video interface (DVI) technology capable of digitally transmitting high-band uncompressed video signals is widely used in the home appliance market. The DVI is a standard created by the DDWG (Digital Display Working Group) to accommodate analog video signals and digital video signals in one connector, and is widely applied to products such as PCs, TVs, and DVDs.

However, since the DVI technology supports only a digital video signal, there is a shortage of support of a digital audio signal and a large size of the connector.

Recently, a high definition multimedia interface (HDMI) standard for transmitting digital video signals and digital audio signals in a single digital interface having a bandwidth of 5 Gbps or more has been developed and announced.

The HDMI is a next-generation digital interface capable of supporting high definition video and audio signals, and having a small number of cables and a small size of the connector, it is convenient to use. Although home appliances with HDMI interfaces have not been released yet, the world's major home appliance manufacturers are planning to launch products with HDMI interfaces.In the home appliance industry, digital TVs, set top boxes (STBs), DVD players, etc. In the same home appliance, the adoption of the HDMI interface is expected to be active.

1 is a diagram schematically illustrating a configuration of a video display device employing an HDMI interface. The video display device includes an HDMI connector 10, an HDMI receiver 12, and an image signal processor 14. And a display panel 15, a voice signal processor 16, a voice decoder 18, a speaker 19, and a controller 20.

The HDMI connector 10 receives a digital video signal and a digital audio signal in combination with a cable of an external device according to the HDMI standard and transmits it to the HDMI receiver 12.

The HDMI receiver 12 decodes the input digital video signal and the digital audio signal, and transmits the digital video signal to the video signal processor 14, and the digital audio signal is passed through the audio signal processor 16 to the audio decoder 18. To send.

The video signal processor 14 converts and processes a digital video signal input from the HDMI receiver 12 into a signal suitable for the display panel 15, and the audio decoder 18 is input from the HDMI receiver 12. The audio signal is converted into a signal suitable for the speaker 19, and the control unit 20 controls the operation of all components of the video display device.

Such a device is usually connected to the Internet and receives information through the Internet, but since the main function is to simply receive external information, the device is not a substantially interactive device.

At this time, smart TVs based on the operating system of smartphones are generally the main axis of platform expansion in the Digital Home environment, and the actual detailed components are almost the same, but only new expensive equipment is purchased according to different operating systems. In terms of consumers, the burden is very burdensome.

An object of the present invention for solving the above-mentioned problems is a peripheral device of a video device capable of connecting to the Internet. In particular, high-definition multimedia for transmitting a digital video signal and a digital audio signal in a single digital interface having a bandwidth of 5 Gbps or more To provide an application device that can be utilized as a smart device based on Android (Android ICS (4.0)) video device having a connector slot according to the Interface (High Definition Multimedia Interface; The present invention provides a sliding type portable device for using a video device having an HDMI connector slot employing the structure of a conventional USB portable device as a smart device.

In order to achieve the above object, a sliding type portable device for using a video device having an HDMI connector slot according to the present invention as a smart device is characterized in that it comprises a main PCB with a built-in control device chip based on the Android operating system. ; A first connector electrically connected and fixed to one side of the main PCB; An HDMI port terminal unit provided at a front side for connection with a digital imaging system; A sub-PCB having one side connected to a rear end of the HDMI port terminal and electrically connected to a 19pin of an HDMI standard to perform signal matching; A second connector electrically connected and fixed to the other side of the sub-PCB; A flexible flexible PCB for signal connection between the first connector and the second connector; And the HDMI port terminal part is formed to protrude on one side of the upper end of the HDMI port terminal part and penetrates the sliding port through hole formed in the housing for protecting the internal components, and introduces the HDMI port terminal part into the housing or externally. And a knob for protruding from the housing and maintaining the HDMI port terminal portion protruding from the housing.

According to the proposed embodiment, the HDMI interface is developed with a sliding structure to realize convenient portability and function optimization, and it is possible to provide a powerful mobile computing environment based on the latest Android OS ice cream sandwich and ARM Cortex-A8, and user's existing LCD. The convenient and simple streaming plug-in technology that turns HD TV into a smart TV environment can provide the optimal smart platform environment that can utilize various contents such as web browsing, YouTube, email, SNS, games, and so on. It is expected to be able to provide a ubiquitous computing environment that can interoperate with various mobile devices.
