What is the purpose of PSS?
A. The PSS specification defines a multimedia streaming service within 3G wireless networks, and so enables the application scenarios mentioned above, as well as others. An important point is that PSS standardizes the communication used in the service. This makes it possible for vendors to design equipment that will interoperate (i.e. communicate properly with equipment from other vendors). For example, one company could provide a streaming server, and another company could provide the client solution.While the PSS specification is defined to enable interoperable implementations, the specification itself cannot guarantee interoperability. Implementations from different companies must be tested together to ensure that the implementations are correct, and that companies have a consistent interpretation of the specification. Testing is also needed to identify and correct parts of the specification which are unclear or inconsistent.
