The purpose of an add is to sell product.... not piss people off to the point that they will never do business with that company.... the advertisers need to re-consider what they are doing....'splain me this then...
A few days back, I clicked through some links, likely starting here, got to the Canon Europe CPN site, augured in a bit further to this page.......
OK Canon, I've been lured in, advertising is successful so far, now I'd like to watch the video, maybe I'll get more interested in your product(s).
But, the video won't play, according to Chrome on PC, the video stream is blocked, possible causes include.........
Adservers, analytics, whatever else, I'm already there Canon, I've jumped the hoops and hurdles, do you really have to further analyze the traffic that has already passed the road blocks? You'll get no clue whether I'll actually purchase this specific product or not, what else could you possibly care about?
I'm not an IT guru by any means, but it looks to me like the port needed to play the video is blocked. This could be a problem with the configuration on your PC (firewall settings perhaps), your home cable or DSL modem (whichever is applicable), your router if you have one, or it could be something that your ISP chooses to block for some reason. I once ran into a problem like this for video streaming, and I worked with my ISP to get it resolved.
The majority of users have no idea how the internet works, and quite reasonably most don't care - they just want it to function properly every time they use it. However, the process of supporting a wide range of services between a server and a computer which may be located almost anywhere in the world (and could in fact be moving, on a bus or a train for example), is far from trivial. The internet is a distributed network operated by a vast number of different companies, and often there are multiple interpretations of the standards they are trying to support. To me it is far more incredible that it usually works as intended than that there are occasional glitches.
Big companies like Canon with lots of resources to devote to their websites generally put a lot of effort into making sure the content is accessible to as many people as possible, because as you note it is in their best interest. So when you encounter a video that won't play, more than likely the problem lies at your end or somewhere in between, as Canon will do their best to make sure the video plays under every possible scenario. Most of the variables are outside Canon's control, so unless a lot of people report the same problem it is probably not their fault.
For the record, the video plays perfectly with Chrome on my PC, even when accessed through a company firewall and a VPN. That's actually quite impressive, if you think about it!
I'd suggest you contact your ISP to see if they can help.
