The HTTP protocol allows the clients to identify themselves using a user-agent header field. This enables distinguishing the Portal Application software, usually for statistical purposes or for tracing of protocol violations.
The KreaTV Portal application will identify itself with a user-agent string similar to this:
Motorola KreaTV STB (Linux)/WebKit
On the client side (in the IP-STB) it is possible to find out if a
portal page is displayed on a KreaTV IP-STB by checking for the
existence of platform services, for example
the informationService
object.
