Color Bars at the beginning of TV episodes

[DataMeister]

I was ripping a TV show from a Blu-ray and the beginning of each episode contains a color bar test pattern for about 60 seconds. However playing the Blu-ray in a player doesn't show these bars.

Is there a reason this might happen?

Thank you. I tried searching for color bars, but that didn't bring up any of these threads.
