Bestv TV needed to deliver smooth ultra-HD live broadcasts for sports events and exclusive performances even when network conditions fluctuated and very large audiences surged into streams at once. It also wanted to improve perceived picture quality for motion-heavy scenes and celebrity close-ups without forcing every broadcast to run at the highest possible bitrate.
Reported impact
Bestv TV improved the visual experience of high-concurrency event streaming while keeping transmission stable under difficult network conditions. Alibaba Cloud's live-video stack let the platform combine lower-bitrate delivery with clearer images, stronger burst handling, and better resilience for major sports and entertainment broadcasts.
Bestv TV used Alibaba Cloud Video Live as the base for an AI-enhanced live-streaming workflow tuned for sports and performance events. Incoming live video is processed through Narrowband HD 2.0, which applies adaptive encoding to reduce bitrate and then uses generative detail restoration to recover visual clarity lost under constrained transmission conditions. For distribution and resilience, MediaUni supplies a globally scaled delivery fabric with thousands of nodes and large bandwidth reserves, plus disaster-recovery plans and automatic primary/backup stream switching when interruptions or frame-rate anomalies occur. Bestv also deploys custom transcoding templates and AI restoration models, using portrait-oriented settings for concerts and detail enhancement for basketball so faces, jersey numbers, floor textures, and court lines remain clearer. The design combines bandwidth efficiency, AI-based image restoration, and high-concurrency delivery in one production live-video pipeline.
Live event streams enter Alibaba Cloud Video Live, where Narrowband HD 2.0 and custom AI restoration models transcode and enhance the video before MediaUni distributes it through the global delivery network. During peak events, reserved bandwidth and primary/backup streams keep the signal available while viewers receive clearer images at lower bitrates.
Bestv also used event-specific transcoding templates and AI repair models to improve concert facial detail and basketball scene clarity. (original: 针对赛事和演唱会定制不同转码模板和 AI 修复模型，如针对演唱会的人像定制模板对偶像面部和肤色进行特殊处理……针对篮球直播赛事的转码模板和 AI 修复模型让球衣数字、地板纹理、球场边界线更加清晰。)
