Description

Multi-Channel Audio-Video Output Device

The present invention is to allow a user to selectively connect to a multi-channel image and sound providing medium to enjoy moving images and corresponding sounds in three-dimensional sound, and more specifically, a set-top box and a voice amplifier in a housing having a woofer speaker The present invention relates to a multi-channel audio-video output device capable of reproducing and transmitting various moving images and sounds selectively input from a broadcasting satellite, the Internet, a DVD player, and the like.

Generally, as an apparatus capable of reproducing and outputting sound, an audio component including a tuner, a CD player, a cassette tape player, an amplifier, and the like as an integrated device is representative.

In addition, each component constituting the audio component functions as a separate playback device, and an MP3 player for reproducing a media file such as MP3 has been developed and has been in the spotlight as a sound playback device.

In order to have a video output device added to the sound reproducing apparatus to simultaneously produce a video output and a sound output, an integrated device in which a video reproducing apparatus is combined with an audio apparatus may be developed. It refers to a form equipped with multi-channel speakers to enable a three-dimensional sound listening, not the same form.

However, conventionally developed devices capable of listening to three-dimensional sound in addition to moving images usually consist of a large projection TV, various external audio devices and a plurality of large speakers connected thereto.

Therefore, the installation is impossible in a narrow space due to its large size, and is sold as an integrated device, but since each component is mostly external, installation is complicated and it is difficult for general users to easily use.

However, it is difficult to construct a video output device such as a TV or a general speaker as a single unit, so at least an audio device such as an amplifier or a tuner that outputs sound is integrated, and a woofer speaker in charge of the bass region is added. There is a demand for the development of a device that can be integrated integrally.

In addition, as the Internet is becoming more common and digital satellite broadcasting is being followed, the importance of devices capable of outputting various video media in the multi-channel multimedia era is not limited to simply outputting broadcasting signals transmitted from cable broadcasting. Is rising.

As a result, devices that can break down the boundaries between computers and general home appliances, such as set-top boxes, are being accelerated, but development and subsequent generalization are still far from complete.

Therefore, the present invention was conceived in view of the above-described conventional problems, and the first object of the present invention is a built-in set-top box to selectively output video and audio signals (data) from media such as the Internet, digital satellite broadcasting, DVD, etc. It is to provide a multi-channel audio-video output device that can be provided and output.

In addition, the second object of the present invention is to include a multi-channel amplifier and woofer speakers, and a terminal for connecting to an external speaker and a monitor so that a moving picture output to the monitor can be viewed along with a three-dimensional sound including low and high ranges. It is to provide a multi-channel audio-video output device.
