I had the chance to attend the HbbTV Symosium in Paris last December. Here are some interesting slides I collected.
HbbTV is now really on the launching ramp.
ProSieben channel in Germany reports 1.4M connections of unique TV set to its HbbTV service per month with a growth of 20%.
More intersting is the usage of HbbTV to improve the experience of impaired people.
Sign language assistance is available through HbbT for hearing-impaired
Improved contrast and font size are also available for visually impared people.
So HbbTV is not only introducing interactive advertizing as one often reduces it, but also improving the whole TV experience.
