Topics in the track
In this topic, will introduce the general solutions for QoE optimization in different industries, and share XueErSi's practice specifically for online-education scenario, about how to use data collection & analyzation mechanism to drive technology upgrades, production improvements and live-broadcast specifications.
In the field of live games, the balance between clarity and fluency has always been a pain point in the industry. How to choose the most suitable resolution and rate gear for users is a big problem in the industry. This presentation will bring the fast-handed in the streaming protocol-based live multi-rate adaptive framework, how to use data to drive deep tuning in the player, CDN, algorithm and other links, and get QoS and QoE improvement.
Several common misunderstandings of multimedia quality evaluation will be introduced. Some ideas which are needed to be considered when design a new product evaluation system will also be discussed. Taking real-time scene as example, the practices relevant to QoE and some evaluation tools of ours will be proposed in presentation.
