This industry is dominated by vendors who make money selling boxes
(at the cell tower or
upstream), they came from a regulated world and an ITU type
development process that engenders
lots of pieces in the signal path (thus lots of boxes), and they have
gotten advice from the
major content industries, who, when asked, will always say that they
want authentication and DRM and etc.
(of course, without feeling a need to pay for their development),
thus putting more boxes in the signal chain.
This gives rise to very complicated and expensive signal chains,
which apparently suits many major
players just fine. If you doubt me, look at all of the pieces in IMS.
Or BCMCS. Or DVB-H.
In other words, DSS is much too simple for what they perceive their
needs to be.
Of course, the ability of this ecosystem to predict its future is not
that great either, so it may be
that all of this complexity will just be another few wasted billions
of USD, and it even may be that
DSS will win in the end.
