Description

[0001] Apparatus and Method for Providing Wireless Audio Streaming Service [0002]

The present invention relates to a device for providing a wireless audio streaming service using a smart device and a dongle device for converting audio of a media device to wireless in order to transmit audio of a public media device in a public place to a smart device and provide audio service through the smart device, ≪ / RTI >

Generally, large-sized TVs and multivision are installed in public places such as banks, train waiting rooms, bus waiting rooms, and resting places of subways. In addition, LCD panels are installed inside the subways and trains to provide a sight to passengers. On the roof of a large square or a building, a large screen is installed to display a predetermined advertisement or to broadcast a broadcast such as a soccer game .

However, in the case of an outdoor broadcasting terminal such as an LCD panel, a large TV, and a large screen installed and operated in public places or outdoors, the output volume of the audio signal is set to be very low due to the work or noise problem inherent in a public place, .

Accordingly, viewers who actually watch the broadcast content can not understand the broadcast contents properly, and relies on a certain guess or accepts it without meaning through the subtitles displayed on the screen, so that even if an expensive broadcast terminal is installed at a high cost, It has not been possible to fully demonstrate the above.

Further, since a remote controller capable of controlling the volume of such broadcast terminals installed in a public place or outdoors is not provided due to failure or the like, it is recognized as a very unreasonable administration from the standpoint of viewers who should enjoy the convenience given by such a broadcast terminal There was also a problem.

In order to overcome such a problem, there has been developed a method of allowing a user to listen to broadcast audio by having a predetermined number of headset devices that can be used by an individual. However, this method requires not only a separate headset device but also a separate And there is a problem that the possibility of loss is very high.

Meanwhile, various technologies for wirelessly transmitting multimedia contents between smart devices having computing and networking functions and smart TVs are being commercialized. For example, Google's Chrome Cast connects to an HDMI port on a smart TV to receive audio or video via WiFi and plays it on a TV, allowing users to connect to YouTube, Google, Play Music, Google Play Movies, and other content can be viewed on a TV connected to Chrome Cast. In another example, Miracast can transmit multimedia between two devices connected via Wi-Fi Direct, similar to Bluetooth technology. As another example, Apple's AirPlay can stream multimedia content from Apple devices (iPhone, iPad, iPod Touch) to other devices wirelessly with that information.

However, the above-described air play and mirror cast have a limitation in that they can be used only if both the transmitting device and the receiving device support the technology, and in the case of chrome casting, there is a limit to the technology of reproducing web contents through a TV.

The present invention provides an apparatus and method for wirelessly transmitting audio output from a media device installed in a public place or outdoors to a smart device possessed by a user so that the user can view a broadcast output from the media device regardless of the surrounding noise.

The present invention provides an apparatus and method for receiving audio from a smart device possessed by each individual without requiring a separate headset device for receiving an audio signal.

The present invention provides an audio streaming dongle apparatus and method capable of wirelessly transmitting audio of a media apparatus without having to separately produce a media apparatus.

The present invention provides a method for providing a wireless audio streaming service received from an audio streaming dongle device connected to a public media device, the method comprising the steps of: downloading and installing an application for using the audio service of the public media device; Receiving the audio signal output from the public media device from the connected audio streaming dongle device, and outputting the received audio signal.

A method for providing a wireless audio streaming service in an audio streaming dongle device, the method comprising: receiving an audio signal from a connected public media device; converting the audio signal to enable wireless transmission; And streaming to at least one set of smart devices.

The present invention relates to a smart device, comprising: a wireless communication unit for establishing connection with an audio streaming dongle device in the vicinity; an audio receiving unit for receiving audio signals output from the connected media streaming dongle device from the connected audio streaming dongle device; And outputting the processed audio signal.

The present invention relates to an audio streaming dongle apparatus, which comprises an audio input unit connected to a common media device for receiving an audio signal, an audio signal converter for converting the audio signal to enable wireless transmission, And a wireless audio transmitter for streaming to the smart device.

According to the present invention, a user can wirelessly listen to audio from a media device installed in a public place through a smart device carrying the audio. For example, it is possible to watch TV while listening to the audio of the TV through the earphone of the smart device, without disturbing the examinee at the home where the candidate is present. In addition, when a large screen is shared by a large number of users in a waiting room such as a train station, a bus terminal, an airport, or a public place such as a karaoke room, the user can listen to clear audio using his or her own smart device . In addition, even if there is no TV audio at a designated place such as a hospital hospital room or a bank customer waiting room, the user can listen to the audio through watching the TV through the earphone of his / In addition, it is possible to listen to the interpreter's audio using the portable smart device of the user rather than the expensive interpretation device in the place where interpretation such as a meeting is required.

Also, according to the present invention, the service provider can utilize the user's smart device as a customized advertisement and information providing screen. In addition, the wireless audio streaming apparatus of the present invention can be installed in a built-in TV or an audio device, thereby enabling the same type of service.
