I was wondering if there are companies or tools around that do testing of MHP compliance of applications?
I see a testing suite for set-top boxes, but are their equivalents for applications?
can someone point out some resources please?
There are no formal test suites for testing application interoperability. The MHP knowledge base (http://www.mhp-knowledgebase.org/index.html) has some information about this.
Most broadcasters will test applications on their own STB farm (or on one belonging to an industry body like the DGTVI in Italy) before broadcasting them.
Try XletView: http://sourceforge.net/projects/xletview/
It does not implement all of the MHP functionality, but can be successully used to test many of its features. Its probably the best open-source MHP emulator.
