PNC Arena specifically lists tablets, Nintendo DS, e-readers as prohibited.
Consol Energy Center does not list those specifically, so it isn't a NHL policy:

No bags, back packs, air horns, cooler (hard/soft sided), thermoses, large purses, cans, bottles, flasks, alcoholic beverages, laser pointer, video or audio recording devices, professional cameras/lens, tripods, banners or signs on poles, weapons or any other items deemed dangerous and/or inappropriate.
Small purses, camera cases, binocular cases and diaper bags will be permitted, however, all items that do not pass security must be returned to vehicles.
I'm wondering if it's more of an annoyance to your neighbors, rather than an actual recording/streaming issue.
