I'm a sports nut and have noticed when watching games that my signal is delayed. For instance, I'll be on the phone with somone and they'll see something occur a good 5 seconds before me...very annoying. It may have to do with the area/apartment I'm in, but I wanted to see if anyone else has experienced this issue and if they were able to fix it. Thanks in advance!
It's a very simple set up with no receivers or anything else. Cable box is connected in to the wall with the newest equipment versions (as far as I know). Certainly there are variables as I mentioned a couple, but my signal is noticably behind. For sports, the online tracking of scores and plays is ahead of my cable, which I know is not normal.
How is that other person watching? Do they also have Comcast? If it's on a broadcast network, it will typically be seen by an antenna user first. There will always be some delay in Comcast's retransmission as they run channels through multiplexers that compress and combine multiple channels into one QAM frequency sent to the boxes Further, if you watch through a streaming device, there may be an additional few seconds of delay.
Different boxes may have slight differences, too. A true DVR may further delay a second or so due to the internal buffer. I'm not as sure about X1, but when I had a legacy box, I could tell it was mostly pass-through if I simply changed channels. If I did any kind of pause or replay on the "live" channel, then even if I went back to live, it would be a few seconds behind (using another TV with a basic DTA as comparison).
