Abstract

The invention relates to the technical field of communication, in particular to display equipment, external sound equipment and an audio output method of the external sound equipment. The problems that the playing delay of the audio data is high after the audio data is transmitted through the network in the WIFI sound equipment, and the left surround sound and the right surround sound are not synchronously played by different WIFI sound equipment can be solved to a certain extent. The external sound equipment comprises a second controller which is configured to receive a first instruction which is sent by display equipment and comprises a first parameter, the first parameter is used for configuring an audio data pool, and the audio data pool stores received audio data; when the data length in the audio data pool is greater than a first threshold value configured by the first parameter, the second controller controls the audio data to actively lose frames so as to shorten the data length, and plays the audio data after frame loss; otherwise, sending a second instruction to the display equipment.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular, to a display device, an external audio device, and a method for audio output of the external audio device. Background technique [0002] With the development of wireless audio technology, wireless audio equipment has made great progress in response time, transmission rate, and convenience, and thus appears more and more in home audio-visual systems. [0003] Wi-Fi is often written as "WiFi" or "Wifi" is a wireless local area network technology based on the IEEE 802.11 standard. IEEE802.11 devices have been installed in many products on the market, such as: smart TVs, audio equipment, personal computers, game consoles, MP3 players, smart phones, tablet computers, printers, notebook computers and other peripheral devices that can access the Internet wirelessly . [0004] However, the transmission of audio data from the TV side to the audio device side requires d...
