It lags behind. All programs I compare with analogue cable, lag behind by 2 seconds. With analogue cable and in the past: radiowave-transmitted TV, there was no such delay. Until today I can demonstrate that difference between digital and analogue cable.
I would not be able to notice it with a delay of not 2 seconds but just 40 ms.

The time differences between analogue & digi cable are mainly the result of various de- and encoding procecces of the didital stream. However usually also the stream which will be transmitted to you analogue is usually digital before and gets converted before by your cable provider.
But you raised an interesting question for me: At which time the teletext gets embedded into the different transmission signals and if the embedded time signal gets an slightly "advantage" so that it reaches the consumer at the right time. Have to check it out with the people who work in the control room of the channel.
PS: The camera zoom at the beginning of the ZDF news is one of the worst which I have ever seen. The travel speed of the camera, the desk and the background differ totally! Maybe they changed it meanwhile, but in the first weeks it looked awful! Bah!
