I was in HK over the most recent xmas and new years. I used the trains multiple times a day, traversing much of the network and almost didn't notices these screens. There is a lot of static adverts displayed and video didn't seem to be utilised much from what I saw. They are just TV screens with sound, nothing more and don't have train approaching tech as HK's trains are driver less. JCD's system is inferior, especially when you factor in the analytics XTD's system provides, whilst it has taken JCD around 4 years+ plus to expanding across HK (take waht you will from that). Although they are a global behemoth, from memory JCD they don't have many major rail advertising contracts, and what they have is limited to Asia or in Europe. When a good friend asked them, JCD replied that they don't have other contracts of scale to implement this system. JCD don't have any of the major US rail contracts, thus their competitive threat (if there is one at this point) is likely limited to Asia and Europe if XTD get around to there at some point. The top networks worth dealing with in the US are mostly split between CBS and Titan 360 (now Intersection after the merger with Control Group) neither of which have a solution for cross-track as they have limit digital applications for other digital advertising in other areas of a metro station.
