Description

BRIEF DESCRIPTION OF DRAWINGS

[0005] This invention will be understood by referring to the accompanying drawings, wherein:

[0006] FIG. 1 is a connecting operation example of the present invention;

[0007] FIG. 2 is a functional and schematic module diagram of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0008] As shown in FIGS. 1-2, a preferred embodiment consists mainly of a set top box with karaoke functions 1 is composed of a video and audio real-time casting function processor 11, an audio/video decoding processor 12 and an audio remix processor 13.

[0009] The video and audio real-time casting function processor is mainly to receive Wi-Fi connection from intelligent terminal equipment, and to download and play the multimedia of karaoke songs. The audio/video decoding processor 12 is mainly to receive signals from the video and audio real-time casting function processor 11 and send signals to the audio remix processor 13, as well as receive returning signals. The audio remix processor 13 is mainly to receive and process the audio receiving module 130 and A/D converter 131 of the microphone, it is able to process the received audio module and video signals of the audio/video decoding processor 12 by mixing them with sound effects, and then send them back to the audio/video decoding processor 12 for the final output to a television or projector.

[0010] The present invention is mainly to receive audio signals (first audio signals) and video signals of the audio/video decoding processor 12 (second audio signals) by the audio remix processor 13. The audio remix processor 13 performs the sound mixing and tuning process on the first and second audio signals, outputs the mixed and tuned audio signals to the audio/video decoding processor 12, performs the synthesis and then outputs to a television or projector after separating the mixed and tuned audio signals from the audio frequency.

[0011] The invention has the following advantages as can be seen from the foresaid description.

[0012] 1. The present invention, a set top box with karaoke functions, is mainly able to perform separation of the projecting video and audio of the microphone, and then carry out the sound mixing process, which allows the output video to achieve more optimized karaoke sound effects.

[0013] While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
