A Comprehensive Platform for Audio/Video Interactive Live Streaming Abroad
Initially, Hago established its app's social profile via real-time voice interaction and text chats; over a period of development, it gradually progressed to highly interactive audio/video scenarios such as voice chatrooms, show live streaming, and video co-hosting.
Hago launched its audio interaction business in Indonesia and Southeast Asia, where the service environment is quite different from that of China.
Consequently, Hago faces the following main challenges:
Poor network quality
Highly unstable network situations result in packet loss, jitter, and high delay, while most users are on a 2.5G or 3G network.
Diverse user phone models
The phone models in many regions are primarily low-to-mid-range, and many Android devices use lower system versions and exhibit poor hardware performance.
Fierce bandwidth competition
Since both game services and audio interaction feature high bandwidth consumption and there is competition for network bandwidth in data transmission, excessive audio traffic may affect game functions.
To resolve the above issues, we have thoroughly optimized real-time audio interaction scenarios:
Optimized audio quality under poor network conditions
Hago has introduced several strategies for superior performance under poor network conditions, ensuring clear and fluent communication quality without freezing even under high packet loss, high delay and limited bandwidth conditions. Regardless of subjective or objective evaluation by audio device, the optimized quality can attain an MOS score > 4 points (the standard range for evaluating audio quality standards is 0-5 points, 5 points being the highest).
Optimized audio bandwidth occupancy
Optimized audio bandwidth occupancy When network quality declines during voice transmission, Hago has optimized bandwidth occupancy to cope with the competition with game service for bandwidth resources arising from successful data upload through data retransmission, thereby effectively reducing the occupancy of audio/video transmission bandwidth under various poor network conditions.
Ultra-low latency optimization
Hago offers high-quality audio/video services while ensuring low latency by virtue of continuously improved service nodes worldwide and transmission technology, optimal access, intelligent routing, and encoding/decoding performance improvement.
High audio quality
Poor network conditions (speed limit, packet loss or latency) are thoroughly optimized, thus ensuring smoothness and optimal experience.
Reduced traffic
Hagao has greatly reduced its traffic through deeply optimized transmission strategy while ensuring the stability and audio quality.
QoS and QoE systems
To manage the complexity and diversity of Android devices, we have established an indicator system related to the quality of experience (QoE) and quality of service (QoS), dynamically performing automatic analysis and active adaptation to all models, thereby ensuring that the platform can be compatible with various Android devices, without issuing a new version by developers.
