The instability of mobile network, high packet loss rate and call quality have always been the obstacles to the good user experience of mobile instant messaging app, and it is also a key issue to be solved in audio and video communication technology. China has a leading audio and video technology of Bai Rui Network based on the mainstream of the current video codec technology and AAC audio editing technology, technology precipitation 10, long-term focus on the field of audio and video technology research and development and innovation.

First Instant Messaging video technology, Bai Rui Technology anychat Adoption of the international leading video coding standard H. MPEG-4 part , H. h) is a new generation of digital video compression formats, which is jointly proposed by the International Organization for Standardization (ISO) and ITU (ITU) following MPEG4. The biggest advantage is the high data compression ratio, in the same image quality conditions, the compression ratio of H. MPEG-2 is more than twice times, is the MPEG-4 1.5~2 times.

Anychat using advanced mosaic technology, to ensure that the video communication process does not appear in the flower screen, mosaic and other phenomena. and also for different clients to set different video quality, including video capture resolution, frame rate, encoding output code rate, quality factor and other parameters, dynamic adjustment.

In the instant communication process voice becomes the most basic and the most important function, the voice acquisition plays and transmits also becomes the numerous instant communication tool's important competition, Anychat uses the advanced AAC audiocoding Speech Coding System, AAC is MPEG1/2 audio Of the next generation of lossy audio encoding, and is the audio encoding used by MPEG-4, AAC uses the perceptual sub-band technology, compared with other encoders such as MP3, AAC encoder greatly improves the data compression rate and sound quality. The system is continuously optimized with anychat, which supports sound processing such as silent Detection (VAD), noise suppression (NS), Automatic gain (AGC), and Echo cancellation (AEC), which greatly improves the user experience.

Instant communication to make friends and relatives of communication breakthrough time limit, so that the office of communication breakthrough limit, so that the communication of strangers breakthrough the limits of the environment, so that the communication between the self and the outside limits the psychological limit, with the 2015 4G network popularization, smart phone more app application, Instant Messaging tools will continue to grow in the coming year. The Anychat Interactive development platform will provide professional and stable underlying audio video technology and communication technologies for a wide range of instant messaging applications.
