With Analog TV the captions are imbedded in video itself and so it always in sync with the video unless someone mistiming the caption when adding it to the video.
With Digital TV
Video and Audio and Caption all have it own tracks seperately so if it not in sync they can seem to either be delayed or going too fast. Same with audio can be delay or going too fast.
So many networks are still learning how to take old analog programming and covert it to digital signal.
When networks convert it to digital it seperate the video audio and caption to it own tracks that networks may have send it over air or on cable out of sync so all seem to be delayed from each tracks
I am sure networks check video and audio tracks carefully but probably did not think about checking caption track too to make sure it in sync too!!!!!
So networks are still learning and it will improve but always let your networks know when it not in sync to remind networks to check the closed caption track to make sure it in sync with video.
