Assero Industries’ Defender Backpack seems tailor-made for assistant directors, unit production managers and production coordinators who must always have their iPads accessible, but would rather keep both hands free. It’s a 4-in-1 pack that provides multiple ways to tote your digital companion — the most obvious being as a backpack.

Here are a couple new products from IK Multimedia that should appeal to iDevice owning voice actors, voiceover artists, and soundtrack singers.

When I’m on set directing, I don’t want any unnecessary distractions… like losing my iPad. Which is exactly what happened a couple months ago. It turned up during a company move, but for those few hours it was missing, I was totally stressed. I joked about making a custom strap, so I could sling my iPad over my shoulder like a laptop bag, or around my neck like Flava Flav’s watch. Looks like someone beat me to it!

The DryCASE lets you take your iPhone underwater! So the next time a great white shark is torpedoing in your direction, you can shoot some awesome iPhone video! That will come in handy when the coroner’s office is trying to identify your body.

As long as I was at the expo, I wanted to cover it for HHH. So, I walked the expo floor, in search of all the latest cool stuff for iPhone, iPod Touch and iPad, and found… well… perhaps you should just watch our comprehensive, and totally complete tradeshow report.

Every so often, we’ll cover a Mac or PC application simply because it ties in so nicely with your iDevice. Such is the case with AlterMedia’s Studio Suite 9, a great looking system for facility and studio management.

As you may remember, we covered Doddle during NAB earlier this year. In addition to showing off Doddle’s primary function as an industry directory, Doddle’s developers teased us with news of some sexy call-sheet functionality they were planning for future versions. Well, the future is now-ish! Doddle was at the ShowBiz Expo, showing off Doddle Pro, complete with the aforementioned sexy call-sheet sexiness! Check out the video below for a spiffy demo.

This is without a doubt the niftiest thing I’ve seen in a while. The Cube by Teradek is a real-time, camera-mounted video streaming encoder. In other words, it takes video from your camera, encodes it into h.264 video, then streams it over a wireless network to your laptop. The video is then immediately available for viewing via your iPhone, iPod Touch, and iPad running the Air Video app. That means instant wireless dailies! SICK!

Calling all DP’s! Chemical Wedding has just released Toland ASC Digital Assistant ($39.00), a new iPhone film calculator unlike any calculator you’ve seen before. It’s totally sick. If the Cray XT5 Supercomputer, and an Arri Elexa had a love child, my guess it would grow up to be Toland.

I had seen it all — Stood in every line, tasted every bit of crap food, and tried not to stare at every scantly-clad booth babe. Yes, I was done with NAB, and heading out the door… when suddenly I noticed this: Blackmagic Designs was using an iPad to control their line of VideoHub routers!
