Frequent problem: In-flight live TV suddenly rewinds about 90 seconds
Mods: I tried to search the forum to see if this has been covered before, but could not find any such thread. If there is such a thread, feel free to move this post, or delete it.
This has now happened to me on enough flights that I am convinced it isn't "just me" and is in fact recurrent glitch: I'm (passively) watching live TV aboard a DL flight, and suddenly it rewinds about 60-90 seconds. This is independent of any in-flight announcements, has nothing to do with the timing of commercial breaks, has no connection to any simultaneous engagement by me with the IFE, or any other correlate. Most commonly when I watch live TV, it is CNBC or CNN; it has happened on both of those networks. It seems to happen about once or twice an hour.
Any ideas what this is all about? Is Delta aware of it? It's rather annoying.

Sounds like Viasat is buffering 60-90 seconds to handle transient outages in the air, but instead of always being 60-90 seconds behind, it's jumping back 60-90 seconds when it loses signal.

As a flight attendant I have never seen this glitch or been made aware of it. Curiously - Have you had this issue on both viasat and gogo planes? If I had to guess the system probably buffers a certain amount of content To keep a continuous stream given connection is not entirely lossless and perhaps something happens during that process?

Lets do some math: Assume it happens every 45 minutes, and the player jumps back 90 seconds. That means it played 2700 seconds of video in 2610 seconds, and then repeated the last 90 seconds. That's 3.4% fast. Hmmm, that's right in the range of the 4% "PAL speed-up" when a 24 frame-per-second film is played on 50Hz based PAL TV's.
FYI, I think I've experienced this TV rewind while watching news on a Delta 739.
