Description

   Wireless audio and video receiving microphone convergence system   

The present invention relates to a wireless audio and video receiving microphone convergence system, and more particularly to a system that receives external sound and audio and video signals, and performs mixing and image processing and output.

With the rapid development of technology, people now pay more and more attention to the quality of leisure life. In terms of singing, in order to enable the user to have a sound of accompaniment while singing, the user can use a karaoke device to play music as an auxiliary accompaniment tool when singing, so as to set off the user's singing voice.

Common karaoke players use Video CD, Digital Versatile Disc (DVD), and Hard Drive as recording media to store accompaniment music information and background animation information, and a song is selected by the user Then, the karaoke player mixes the accompaniment music information stored on the media, mixes it with the user's song received through the microphone, and then plays it through the speaker.

Since not every song accompaniment tape is stored in the traditional karaoke device used by the user, the user will definitely encounter that when using the traditional karaoke device to order a song, they want to sing a specific song, but The traditional karaoke device does not store a backing tape of this particular song, so that the user cannot sing the song that he wants to sing.

Furthermore, many of the current singing software on the Internet and the singing app for mobile phones and tablets only provide personal singing, and cannot put videos on TVs, projectors, etc. to share with multiple people for entertainment.

For the above reasons, there is a need for a video-receiving microphone convergence system that enables users to rely on any portable device as an audio-visual input device, without having to sing in a specific place, such as KTV, and via audio-visual output devices and sound output Connect your device to share your videos with the people around you.

The audio signal is transmitted to the audio output device via a wired / wireless method.

The wireless audio and video receiving microphone convergence system of the present invention further includes an audio and video receiving module, a sound source receiving module, an image processing unit, a sound processing unit, a visual control adjustment (OSD) module, an audio and video processing unit, and an audio and video output module.

The audio and video receiving module receives the first audio and video signal of the audio and video output device, separates it into the first video signal and the first audio signal, and sends them to the image processing unit and the audio processing unit, respectively. The audio source receiving module receives the second audio signal input device The sound signal is transmitted to the sound processing unit. The sound processing unit mixes the first sound signal and the second sound signal through the mixing control module, and generates a third sound signal to be transmitted to the audio and video processing unit and the audio and video output module. The mixing control module adjusts the parameters through the video control adjustment module. The video control adjustment module generates a second image signal and transmits it to the image processing unit. The image processing unit performs image stacking on the first image signal and the second image signal. A third video signal is generated and transmitted to the video processing unit. The video processing unit mixes and superimposes the third video signal and the third audio signal, and converts the second video signal to the video output module, and finally the video output module Send the third audio signal to the audio output device, and the second audio signal to the audio output Device.

The main feature of the invention is that any portable device can be used as an audio and video input device. Through a sound processing unit, an image processing unit, and an audio and video processing unit, by connecting with the audio and video output device and the audio output device, it is not necessary to be in a specific place such as KTV. Being able to enjoy singing makes singing no longer restricted by location and equipment.
