DVD logo in Buses

This time when i went to TN, I noticed that there are "DVD logo" and captions like "Digital Theatre", "Digital surround", "Dolby stereo".

:-)

Having experience in working in DVD, I could know the pain behind getting the DVD Forum certified DVD logo (passing set of test disk), getting DTS & Dolby certification.

I dunno the reason or inspiration behind printing such logos and captions. It might be reason that the buses are equipped with DVD players.

This could be seen in private and also government buses. anyway its fun to see these kinda stuffs.

DVD certified buses. :-)
