Why is the delay (ping) on professional TV video calls absurdly high?

538 views

So many times I see a guy video calling another crew across the country and it can take a solid 5-10 seconds before we hear them reply. I’ve seen kids in siberia with better ping.

They are probably bouncing the signal off a satellite. That would create that kind of latency. No as for ‘why don’t they just use ground connections’… I have no idea.

1) Satellites are typically used unless really close. That causes delay. But even for close connections the data is still high bandwidth, watch a news segment from your cable provider and then watch it on YouTube, you can easily see the YouTube version isn’t as clear.

2) They have some delay if someone bombs the newscaster and starts swearing (this could be done for the whole feed though).

They’re using a satellite. There is a delay, but it’s more reliable than an unreliable internet signal when you’re pushing hi def video out live to millions of viewers

It’s the time it takes to encode and decode digital television.

Let’s say you have an announcer in a studio talking to a reporter in the field. The reporter sees and hears the announcer through a video path, probably through an internet connection. The announcer video and audio is encoded (that can take a second or 2), then it’s transmitted through the internet to the reporter’s location, where it’s decoded so the reporter can see and hear the announcer. That can also take a second or 2. Then the reporter replies to the announcer’s question. That video and audio has to be encoded for transport through the internet (another second or 2) and then decoded at the other end so the announcer can see and hear and added to the broadcast. That takes another second or 2. Total that all up, you get 4 to 8 seconds delay.

It’s because they are using a mobile satellite connection for areas without internet connection. Those have large delays as the satellites are high in orbit. It takes a few physical seconds for signals to be transmitted and received.

They use satellites for the video feed rather than an internet connection. Most communications satellites are in a geosynchronous orbit (rather than low-earth orbit) so the signal makes a roughly 45,000 mile (70,000 km) round trip. This alone creates a *minimum* delay of about a quarter second.

So it’s already been pointed out that this most likely using a satellite. Just as a interesting thought, when you tune in to watch a show see how many seconds it begins after it’s scheduled time, 4K can be around 45 seconds. Really makes those New Years Countdown shows awkward as hell if you try celebrating along.

Everybody in this thread is explaining the mechanism that makes satellite slower than a cell connection, but nobody is really explaining why they’re using the slower satallites over a cell type connection that can fall back to slow satellites if the cell signal cuts out.

If they’re reporting from a warzone it makes sense they would just do satellite, but so often hosts are talking over each other from two different studios.

local news traffic teams reporting from two miles outside the studio on a clear day seem like they could figure out a way to not have a 3 second delay.

The illuminati has to process the video and audio first.

Do you have any example clips?

I’ve worked in broadcasting and haven’t seen anything higher than a few seconds.
