Multimedia Engine
Voice Engine, Video Engine over PC and Mobile IP
Juphoon offers highly optimized Multimedia Engine for mobile video & rich communication services. It allows network operators, OTT (over-the-top) service providers and device manufacturers to launch superb mobile communication applications (like Viber, Skype and FaceTime) with premium quality of voice and video over IP, allowing end users to make standard and HD voice and video calls over wireless networks such as Wi-Fi, 3G and LTE. It can also be employed to offer rich video services (like video monitoring, video games, video share, video mall and cartoon films), for getting users’ attention and thus increasing the ARPU.
High-quality voice and video on every device, even over unreliable and heterogeneous wireless networks
We have optimized voice and video quality over unstable and heterogeneous networks and designed MDM (Media Device Management) to ensure comfortable calling experience on every device.
Intelligent night vision makes video clearer and brighter in the dark
The media engine uses intelligent technology of exposure and image intensification adjusting both brightness and contrast by simulation and digital method, which improves video effect in dim environment and makes image clearer and brighter.

Delivering a smooth and clear voice and video calling experience
Our Multimedia Engine uses industry-leading QoS technology, enabling clear and smooth voice and video calls over heterogeneous networks environment on various mobile devices. FDE-AEC (Frequency domain estimate AEC) is capable to resolve echo issues on most mobile devices. In addition, SPo technology is applied to ensure perfect adaptation of real-time video transfer to bandwidth via adjusting bitrate and frame rate automatically.
Reducing data usage by 30% to 90%
Bandwidth efficient mode is applied to help users saving 30% to 90% on their data plan without a perceived decrease in video quality.
Automatically adapting to device capabilities
Media Device Management (MDM) is designed to collect and store device capabilities and parameters for best video experience in our cloud server. When users make a video call, the app with our Multimedia Engine will get the device’s media processing capabilities and parameters from the cloud and adjust bitrate and framerate correspondingly to optimize video quality and ensure a most comfortable calling experience.
Voice quality can be accepted even when packet loss approaching 40%.
Our Multimedia Engine applies a group of PLC (Packet Loss Compensation) algorithms covering FIR, FEC, RED, NACK and RPSI/SLI. A reasonable voice call is carried on with packet loss approaching 40%, and video quality is acceptable even when the packet loss reaching 30%.
3 days to complete development and integration
Our Multimedia Engine offers abstract and cross-platform ANSI C APIs. With developing documents and samples, developers can complete development and integration very quickly.
