they are
correspondingly decoded and the corresponding actions are
then taken.
By using the proposed methods, the operators can also
provide uniform digital TV user interfaces to the consumers.
In comparison, without using the proposed solution, different
set-top boxes will usually provide different user interfaces to
the consumers.
For the reasons of easy description, the proposed method in
this paper can be called set-top box based solution and the
original universal remote controller based method can be
called remote controller based solution.
