Hello. You probably have Time Warner, this is a cable box problem. The software of the box can get behind it seem (not sure of the exact cause as i did not design it).Try to reboot the cable box by disconnecting it a minute. Note that the problem may come back, if that happen contact Time Warner Cable about it. The network traffic may be too high, network signal quality may be low or the software may enter deadlock loop or retry loop.So essentially it's not a function but a bug. You probably triggered the problem simply by changing channel or something trivial like this.
Studied video technologies before university. I still fix TV's in spare time.
