Zero-buffer live, instant playback
Built for live, streaming, and large-scale video delivery. One service reaches Hong Kong, Mainland, and global viewers with HLS, MPEG-DASH, and MP4 support.
Every plan includes free SSL, WAF, and DDoS protection. Priced in HKD, billed after use, with itemised monthly statements.
Video CDN caches your live streams and on-demand files on edge nodes worldwide. Viewers connect to the nearest node, cutting buffering and the chance of stalls.
A modern video CDN is more than delivery. It bundles multi-protocol support, adaptive bitrate, content protection, and edge security as a baseline for any video business.
A video CDN does more than push signal to viewers. It directly affects subscriptions, ad revenue, retention, and operating cost.
When viewer counts surge, edge nodes absorb the load and the origin serves only cache fills. Live shows, matches, and sale days no longer buckle under congestion.
On phone, tablet, desktop, or smart TV, on 4G, 5G, or Wi-Fi, viewers get smooth playback, lifting average watch time and retention.
Authorisation controls block hotlinking and out-of-region viewing, protecting content investment and licensing terms.
Edge nodes carry static and high-volume video while the origin handles only source content and dynamic logic, so you do not have to scale up every time viewership grows.
No need to rebuild your player or ingest pipeline; the whole live and on-demand setup fits within one business day.
Log in to the UD CDN console, add your live ingest URL or on-demand source (HLS / MPEG-DASH / MP4), and verify your domain.
Choose streaming protocols, adaptive bitrate, signed URLs, and anti-hotlinking rules; manage them via API too, with no change to your existing player.
Point your playback domain to UD Video CDN to go live instantly. Watch concurrent viewers, stall rate, bandwidth, and node distribution from the console.
From protocols and low latency to content protection and local support, combined into one video CDN.
Low-latency live
With low-latency profiles (LL-HLS / LL-DASH), end-to-end delay can drop from tens of seconds to seconds, depending on your setup.
Multi-protocol, multi-format
Live protocols and on-demand files are natively supported, with no extra packager or encoder integration.
One account activates Hong Kong, Mainland China, and global nodes, routing each viewer to the best line by location.
Works with major streaming servers and packagers, pushing 4K / 1080p / 720p / 480p renditions to the CDN; viewers switch automatically by network speed.
Signed URLs (token), anti-hotlinking, and geo-restriction: three controls, used alone or combined.
The console tracks concurrency, bandwidth, and hit rate in real time, split by region and device, so you can adjust during a live event.
Edge nodes back one another up; if one goes down mid-event, traffic fails over automatically with no disruption.
24/7 email, phone and live chat, with a real person responding the moment something happens on event day.

A general CDN mainly caches static web assets (images, JS, CSS). A video CDN adds optimisation for live signals and large video files: low-latency chunk handling, native multi-protocol support (HLS / MPEG-DASH / MSS / HDS), adaptive bitrate, signed URLs and anti-hotlinking, and real-time viewing analytics. If your business involves live or heavy on-demand video, a video CDN is the right choice.
Live protocols: HLS, MPEG-DASH, MSS, HDS. On-demand files: MP4, M3U8, MOV, WebM, AVI, FLV. HLS and MPEG-DASH together cover about 85% of modern streaming, and UD Video CDN fully supports both.
Activate Hong Kong, China, and global region plans in one account; each viewer is routed to the matching nodes by origin. Smart CDN can also direct each region to the best line automatically.
No. UD Video CDN uses China Telecom CN2 GIA lines to nodes around the Mainland, so you can serve Mainland viewers without an ICP filing.
On event day, traffic is distributed automatically across edge nodes while the origin serves only cache fills. For very high concurrency, such as major matches or brand launches, let our sales team know in advance via the form above so we can reserve dedicated nodes and bandwidth.
Use signed URLs (token, issued by expiry and IP), anti-hotlinking (blocked by referer), and geo-restriction (allow or deny by country or region). Configure them in the console or the developer API.
Log in to the UD CDN console, enter your video domain, verify ownership, set cache rules, and point it to UD CDN to go live. No change to your existing ingest server or on-demand storage, and it finishes within one business day.
All Video CDN traffic automatically masks the origin address, with free SSL certificates, a web application firewall, and DDoS protection built in, and no extra security modules to buy.
Yes. UD Video CDN supports high-concurrency live (live commerce, sports), long-form on-demand (OTT, online education), and short-video push (social platforms).
Video CDN handles video (live and on-demand); Dynamic CDN handles API and WebSocket real-time data such as live chat and polls; Smart CDN handles cross-region routing. Run all three together for full coverage of a video business.
