HTML 5 dubious, quote
"While it may not look anything like a website, what we are unveiling today - initially on the PS3 games console - is built using the same technology: HTML and Javascript. The increasing use of standards for playing media, such as HTML5 and CE-HTML (both elements of the the Dbook7 standard for hybrid TV devices in the UK) is making it easier for us to roll this out more widely. So, expect to see it come to other devices in the coming months."
They're demonstrating that HTML 5 is something they've heard of. And here "HTML 5" evidently means "placing a video player in a web page".
Also that it's 300 models of TV-compatible device such as set top box OR overambitious TV set, and not 300 TV models or indeed 300 TV owners as in the dear old days at Alexandra Palace, when BBC TV could be received by a moderately large area of central London. All right, I'd be a bit surprised - a bit - if an Internet-connected product had a geographical limitation as strict as -that-.
