Time:2022-3-30

The first audio and video technology conference of Netease ended in 2021。 Technical experts from many audio and video fields, such as Netease smart enterprise, Netease game, Netease cloud music, Netease Hangzhou Research Institute and so on, gathered together, combined with their own research and experience for many years, to communicate with the audienceWe have jointly discussed the cutting-edge technological innovation of audio and video and shared the practical achievements of audio and video applications, which has brought many new thoughts and opinions to the development of the industry.

As we all know, vision is the main source of information for the perception of all things. Hearing makes the silent information further and become “vivid”. In the era of mobile Internet, online learning, work and entertainment with “good voice and color” are widely popular, and new scenes such as interactive live broadcasting, video conference and remote recruitment have emerged one after another. Behind it is the strong support of audio and video technology, which imperceptibly integrates the online scenes of all walks of life.

Based on this background, the first audio and video technology conference of Netease came into being.Closely focusing on “color” and “sound”, the conference set up two special chapters: “wide vision: vision of video technology innovation” and “sound in its environment: audio technology immersion experience”, the whole process lasted for two days, and a hearty science and technology feast was dedicated to all guests and online audiences.
