The Screen Builder contains an application useful for sending
announcement messages to one or more STBs in a real-time fashion. It is installed as "...DMB Screen Builder\paging.exe". When started with no command line parameters it runs in graphical mode. Command line usage is as follows:
paging.exe <DestIP> <DestPort> <Timeout> <Param1> ... [Param6]
where:
DestIP: The Unicast IP Address associated with a particular STB or the Multicast IP Address associated with a group of STBs
DestPort: The Port on the STB(s)
Timeout: The number of seconds to display the announcement message
Param1: The text string to display - associated with parameter 1. There can be up to 6 parameters
examples:
Send 2 parameters to a single STB to display for 5 seconds: paging 192.168.1.15 3333 5 "unicast hello" world
Send 3 parameters to a group of STBs to display for 10 seconds: paging 228.7.6.5 1234 10 "multicast hello" small world
The screenlist running on each target STB must contain one or more
Overlay assets tuned to the paging address (e.g., port 3333 for unicast) to be able to catch and process these announcement messages.
Lastly, a screenlist can contain both unicast and multicast overlay assets thereby offering the ability to process an individual paging announcement, targeted to a single STB, or a group paging announcement, sent to two or more STBs for simultaneous display.
