Let every online communication stand in front of you like the other party.

As ZOOM is banned in the domestic market, Chinese consumers are beginning to re-find online video conferencing software. Currently, in addition to ZOOM, which is already listed on the US stock market, there are also conferences developed by many startups. software.

The recently-touched “Face App” is a premium video chat tool featuring high definition, high fluency and low latency. Users can open or join video conferences through the app; Conference types and a variety of tools to meet online education, consulting, multi-person meetings and other scenarios.

The founder and CEO of Qingliu Dingdian Zhiwen Tao told that since the video call function appeared, different users of many scenes have begun to rely on this method to save communication time and improve communication efficiency, but high delay, blurred picture card Problems such as Dunton still exist on major social platforms and even professional video conferencing software.

In 2018, the development of low-latency audio and video interactive technology and the provider “Qingliu Dingdian” began to internalize the face App, the team hopes to optimize the experience based on existing scene service software such as video conferencing and distance education.

On September 13th, the App began to enter the grayscale test phase, version 1.1.2, the software already supports Android and iOS systems, and will soon log into the Windows PC. Mac, OTT TV, etc. The current scene and corresponding functions include:

  • Online Music Education: Provides low-latency and ultra-low-latency interactive technology to dramatically reduce latency and ensure teacher-student dialogue in music teaching while maintaining audio and video quality Online training for chorus needs. At the same time, it provides multiple teaching tools to enrich the teaching scene.

  • Online Discipline Education: Provides a clearer, smoother, and less time-delayed video interactive experience that allows you to see the teaching scenarios and enhance communication efficiency and experience.

  • Online Counseling: Directly provide a video interaction experience that is clearer, smoother, lower latency, and better sound quality, allowing consultants and visitors to join the same online meeting. The privacy model enhances mutual trust and helps users gain a better communication experience.

  • Online Video Conferencing: Directly provide a clearer, smoother, lower-latency, better-quality video interactive experience, support for 1-on-1 and multi-person conferences, and support for group feature quick invitations Friends meeting, support fixed meeting room function to facilitate users to continually hold meetings with the same theme.

Among them, the music therapists who participated in the interviews learned that, like many psychotherapy and psychological education jobs, the therapist needs to quickly and clearly grasp every detail of the user’s reaction during the treatment process. Including body language, facial expressions, etc.

The music therapist told told, “In the past, when we used products such as WeChat video, high latency would make it difficult for us to quickly capture and make decisions about the next treatment. During the communication, both parties are easily formed due to high latency. The situation of ‘beating the mouthpiece’. After using the face-to-face app, these two pain points have basically disappeared.”

In addition to the centralized application scenarios described above, telemedicine is one of the things that can be achieved in the future. Wentao said that the center facing the current stage is still in the field of conference, education and rehearsal, and Qingliu Ding Point will continue to research and upgrade technology.

Technology, Qingliu Dingdian has long been engaged in the research and development of audio and video core technologies, such as the ultra-low latency interactive technology introduced earlier, and the related products using this technology can already enable users to realize online chorus and instrumental ensemble. This type of work is currently difficult to complete with online audio and video software. Specifically, the core technologies and barriers included in the face-to-face app are:

  1. Ultra-low latency audio and video interaction:End-to-end delay delay can be reduced in the case of clear, smooth, low-calorie video Up to 40-50ms, it is one-fifth of the delay of the mainstream video communication software in the market, which can meet the scenes with high delay requirements such as online band, online training and music teaching.

  2. Low-latency audio and video interaction: Dynamically adjust the delay effect according to different quality levels and fluctuations of the network when the video is clear and fluent and low. The ios device delay can be as low as 50ms, and the Android device can be delayed to 100ms, which meets the needs of users in different scenarios

  3. MP Technology: Multi-Path multipath technology, which can simultaneously transmit data using multiple networks (such as WiFi and 4G), reducing the transmission instability of a single network, thereby reducing the card. Rate, improve the audio and video communication experience.

  4. Video optimization technology under medium and weak network: AX technology, SVC coding technology, MP transmission technology, etc., greatly reduce the network of the card, the improvement of the experience under the weak network obvious.

  5. Complete independent intellectual property rights:From the underlying transport protocol to the upper-layer application, the direct app has complete independent intellectual property rights and does not depend on WebRTC, QUIC and other projects.

Wen Wentao said that the face-to-face positioning is a tool app, not a social platform, so its business model also uses time as the billing unit, and customizes different functions and prices according to different usage scenarios. For example, services such as double meetings that do not require ultra-low latency and multi-view capabilities are less expensive than online bands because they require lower latency techniques and more camera angles. “The current pricing is about 2-5 yuan per minute, but we are also continuing to adjust based on user feedback. As a whole, our annual usage fee is about one-third of ZOOM.”

The team that has been facing the team has more than 10 people. It is expected that the official version will be on sale in November. The team will still belong to the Qingliu Ding point at this stage, and will be separately financed after the split.
