Why is there such a long delay?

I started to notice recently that channels are delayed behind real time.  It's most noticeable when watching news programs that have a clock fixed on the screen.  So the time on the news will show 8:25am, but the actual "real" time is 8:26am.  I compared it to the time on my phone and computer, and the broadcast is almost exactly a full minute behind real time.  It's not just live news either.  I have noticed it during regular broadcasts on other channels too.  I could see maybe 10 or 20 seconds, but why such a long full minute delay?

When you are watching via any streaming device, it is a longer process, to get the signal to you, than watching TV with an over the air antenna. Watching over the antenna, the signal goes directly from the transmitter to you.

Watching over a streaming service the same signal has to be sent from the TV station to the streaming service, run through their system and processed for the Internet, then sent to you.

Have more fun. Run the same program on a laptop, tablet,  and main tv, if able, probably see programs at slightly different points.

If you have a another device hooked to the main server you will also see a delay between the two.  There is the processing time for each device from the studio to the final TV. Digital transmission does take some time to progress through the "system".

There is no telling which device taps into what server. I get a chuckle when the same program shows different adds. Just a reminder this is not cable.

Think about how many steps a signal has to go through to get to your TV.  From the camera to the control room for selection of this video.  Also, the initial picture is analog so it has to be converted to digital.  Then this digital signal is sent to some server which then puts it onto the internet for distribution to the network stations.  Even if this signal is transmitted by fiber there is some transmission time.  As a point of information, the velocity of propagation in fiber is SLOWER than in cable and cable is not at the speed of light. It has a Vp depending on the dielectric constant of the cable.

Now, this digital signal has to be converted to either a QUAM or 8VSB analog RF signal, sent to the satellite, back down to your receiver, demodulated into digital again, and then sent to your TV.  Not the fastest way but this provides an error-correcting packet for viewing.

When you think of it, it's pretty slick.

This is not an all server issue.   I have multiple TVs in my garage for sports viewing.  Two use DirectTV stream on Samsung OS, one has a roku.  All devices show 200mbps+ connection. 

The same app on the same channel all Ethernet connected to the same network, the Roku display is always about 30-45 seconds behind the others.  

This is actually quite annoying for big live  sports events.  App notifications and texts from others watching same event come through before the roku displays them.  

Sure you can silence your phone, but for something like the local team being in the World Series, the neighbors cheering an almost a minute before you see them is no  fun.   

This issue is persistent on 3 different models of roku, wifi as well as wired.

There is computer processing time associated with each provider.  ROKU may be getting its program information from sources that have already done post-processing and reconversion.  This will add considerably to the overall transit time.  I have seen a delay between the main TV next to the DirecTV server and another TV connected by MOCA. It is at least a one-second delay.

Ansky360.  I have both Direct TV Stream and Direct TV Satellite and when watching the same program on both services and toggling between them, there is an "almost" 1 minute difference.  That's a lot and it didn't used to be that way.

We'd like to confirm if you're getting the same results with all the channels or just one. Also, when did you start having this delay? Thanks in advance.

I was not complaining, just stating a fact.
