Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0028] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

[0029] Unless otherwise def...

Abstract

The invention provides a low-delay transmission method. The low-delay transmission method comprises the steps that a USB Audio module acquires audio data of a user; and the USB Audio module directly calls a USB driving layer interface on an application layer of the karaoke device according to a preset call link, and sends the audio data to an audio output device for playing. According to the low-delay transmission method, the USB audio module can directly call the USB driving layer interface on the application layer, the UAC standard transmission protocol is achieved, the method does not depend on the system processing flow, and even if the system does not support the USB audio function, identification, control and data transmission of the USB audio equipment can be achieved. The transmission frequency is greatly reduced, and the real-time transmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of information transmission, in particular to a low-delay transmission method and system. Background technique [0002] There are all kinds of karaoke equipment on the market, and they all face a very big technical difficulty, which is delay. When our voice passes through the microphone, then through the system and then output by the speaker, the link is very long, and the information transmission delay is relatively high. If the delay If it is not handled well, the interval between the voice you sing and the voice output by the speaker will be very long, and you will hear two voices, which will greatly affect the user experience, which is also the biggest threshold of the karaoke system. Moreover, the Karaoke APP also has a scoring function. Uploading voices for scoring is another link. How to combine with the Karaoke APP to reduce the workload is another threshold. [0003] The current karaoke equipment n...
