Seoul, and the connections it runs on
Seoul is the capital of South Korea. With about 10 million people, Seoul is one of the largest cities on Earth — and its mobile networks are shared by millions at the same time.
Beyond Seoul
Heading to Incheon (about 27 km) or Daejeon (140 km)? Your library goes with you — the server stays at home and the app adapts as the signal changes on the way.
Crossing into China? Dalian is about 493 km away — the app works abroad too, and on roaming data the low data use counts double.
How much data a film uses in Seoul
In our measurements a film in full HD uses about 1.0 GB per hour on Silux Media, against 2.5–2.7 GB on Jellyfin and Plex for the same picture. A 5 GB mobile bundle in Seoul lasts about 8 hours of 720p instead of 3.7.
When Seoul sits down to watch
Local time in Seoul is UTC+9, with no clock change. Between 19:00 and 23:00 local (10:00–14:00 UTC) shared networks are at their fullest, which is when Silux Media's lower data use matters most.
Seoul gets about 9 h 34 min of daylight in mid-winter and 14 h 46 min in mid-summer.
Questions from Seoul
How much mobile data does a film use in Seoul?
About 1.0 GB per hour in full HD and roughly 0.6 GB in 720p, from our measurements — against 2.5–2.7 GB per HD hour on Jellyfin and Plex at the same picture quality.
Can I watch my films in China?
Yes — the server stays at home in Seoul and you watch from anywhere, including Dalian about 493 km away. On roaming data the lower data use makes a real difference.
Will it work on the way to Incheon?
Yes. On the roughly 27 km between Seoul and Incheon, the app re-checks the connection every three seconds and keeps playing — dropping to a lighter quality in weak spots and climbing back up after.
Can I watch my own films in Seoul?
Of course. Your own server holds the films; the apps for phones, tablets and TVs play them in Seoul or wherever you take them.
Does it help on crowded city networks in Seoul?
Yes. Using less data per minute means a stream needs less of a busy cell or Wi-Fi network — so it keeps playing when others start to buffer.
What's the busiest time for streaming in Seoul?
Evenings — roughly 19:00 to 23:00 in Seoul, or 10:00–14:00 UTC. That's when a stream that needs fewer megabits has the edge.
