Description

A system and method for changing the connection type of an HDMI dongle,

In the following embodiments, a connection form of a Wi-Fi connection between an HDMI dongle and an HDMI dongle is connected between two devices including a user terminal, an HDMI dongle and an AP (Access Point) To a connection.

Many simple IT devices that use Wi-Fi at home are being developed. The most representative example is a High Definition Multimedia Interface (HDMI) dongle that allows you to watch broadcasts from your TV to your Internet connection.

The HDMI dongle receives a stream wirelessly and outputs it to a display device (for example, a TV) connected via HDMI. At this time, the HDMI dongle can wirelessly receive a stream from a user terminal or an AP (Access Point) according to the connection type.

The HDMI dongle can be connected and served in the following two connection forms. The connection mode for receiving the wireless stream from the user terminal in the HDMI dongle will be referred to as a first connection mode in the following description, (AP) is referred to as a second connection form in the following description.

The first connection mode is a connection mode in which the user terminal operates as a hotspot and the HDMI dongle is connected to a user terminal and wirelessly receives a stream and outputs the stream to the TV. That is, the first connection mode is a form in which a user terminal operating as a hotspot and two HDMI dongles are wirelessly connected.

The second connection mode is a connection mode in which an HDMI dongle is operated in an application (App) of a user terminal, a HDMI dongle is connected to an AP in the vicinity, and a stream is received wirelessly and output to a TV. That is, the second connection mode is a form in which three APs, a user terminal, and an HDMI dongle are wirelessly connected. At this time, the user terminal and the HDMI dongle operate as a station.

When the service connection configuration of the first connection type or the second connection type is completed, the user transmits a stream of the content of the user terminal through the DLNA (bubble upnp) app of the user terminal to the HDMI dongle, So that it can be watched.

DLNA is an abbreviation of Digital Living Network Alliance. It is a protocol for sharing and reproducing various media contents (music / photo / video) through the network between DLNA products. DLNA can be composed of DMS, DMC, DMR, and DMP.

A DMS (Digital Media Server) is a device that has content to be shared and enables the contents to be transmitted to other devices connected to the network.

A DMC (Digital Media Controller) is a system that finds a list of contents distributed by a DMS and connects them with another device (DMR) that can execute the content, thereby controlling operations such as content reproduction.

DMR (Digital Media Renderer) is a device that is connected to DMS by DMC and can reproduce contents selected by DMC.

DMP (Digital Media Player) is a device that searches contents list distributed by DMS and selects contents and play them.

The user terminal may be a DMS and a DMC, and the HDMI dongle may be a DMR.

If an external dongle and a user terminal are configured as a station with an external AP as in the second connection mode, a connection configuration by another AP through the setup application (app) of the user terminal, or a first connection mode in which the user terminal becomes a hotspot There is no problem in changing to a connection configuration.

However, when the user terminal becomes a hotspot without an external AP as in the first connection form, the service connection configuration becomes impossible to change to the service connection configuration by the external AP through the setup application (app) of the user terminal. The reason for this problem is that if the user terminal turns on the hot spot, the Wi-Fi function is automatically turned off, and the user terminal can not search neighboring APs after this, This is because the user can not show the neighbor AP list. The WiFi and hotspot functions of the user terminal are mutually exclusive and can not be turned on.

In the case of an existing HDMI dongle, the following process is required to change from the first connection mode to the second connection mode, which makes the user feel very uncomfortable.

In the first step, the hotspot function of the user terminal is turned off and the Wi-Fi is turned on.

In the second step, if the HDMI dongle is disconnected from the user terminal, the HDMI dongle changes to a soft AP to broadcast a Wi-Fi beacon.

In the third step, the user terminal and the HDMI dongle are connected to the WiFi through the setting application of the user terminal.

In step 4, one of the APs searched around by the setting application of the user terminal is selected, and is set to the second connection form through the selected AP.

Therefore, there is a need for a method that makes it easier to change from a first connection type to a second connection type.
