if you will take a look on IPP sample package you may find many examples of threading on top of IPP. Not with TBB (we plan to have such sample in future) or boost but with OpenMP API and operating system threading API.
I would refer you to JPEG sample (UIC) for OpenMP threading and UMC MPEG2 sample for OS threading. These samples might be not so simple but still can provide a general idea of how to do threading on top of IPP.
Note, TBB itself has many samples/tutorials, not based on IPP though.
