STB Authentication
There are two ways (STB IP address or user PIN) to authenticate and authorize Set-Top
Boxes in the ETV Portal Server. STB access control is slightly different from PC and
Macintosh-based authentication (which uses the commonly employed User Name and
Password mechanism). The two methods are outlined in the table below.
Table 12. Authentication Methods
Note The remaining options for
Resource Groups
(beginning with
Add/Modify Live
Channel Privileges
) are the same as those described earlier for individual Users on
page 81. The only difference is that the descriptions will apply to resource groups
rather than to individual users.
Method Description User Interaction Comment
User PIN If Access Control is
enabled, but the STB is
not defined in the system,
then Access Control
works based on a user
PIN. This PIN is defined
on a
per user (not per STB)
basis, so that users need to
be defined for this to
work.
When the user logs
into the system, they
will be prompted for
their PIN. The user
simply enters the PIN
with the remote
control or the wireless
keyboard, and can
then access the video. This implementation is appropriate
for environments where multiple
users with different privileges will
be accessing the same STB. An
example of this would be a shared
classroom where multiple teachers
are accessing the STB at different
times.
STB IP
Address or
Host Name The ETV Portal Server
system determines the
content that the STB can
view based on its IP
Address or Host Name. No user interaction is
required. The user
simply turns on the
STB and only the
content that the STB
user can view id
displayed. This implementation is similar to a
cable TV setup, e.g. if the cable
plan does not include CNN, that
channel cannot be viewed. This
implementation is easiest for end
users because you do not have to
remember user names or PINs. It is
appropriate for environments
where one or a few people with the
same privileges access the same
STB.
