Envivio today launched its HD television platform which makes it possible for iPad owners to tap stream video content to their devices. Envivio‘s 4Caster platform is meant to be leveraged by content distributors like movie publishers and television broadcasters who can use it to stream to their audiences.

“Apple devices have been tremendously influential in driving consumer interest in Mobile TV services,” said Julien Signes, President and CEO at Envivio. “The combination of Apple’s brilliant displays and adaptive streaming technology with Envivio’s video over IP platform and compression technology deliver the quality of experience that has driven most successful Mobile TV service launches to date. One only has to look at to the reviews posted to iTunes by users themselves to see the importance that quality has on capturing the interest of subscribers. The iPad promises to open entirely new dimensions of content consumption and Envivio is pleased to deliver the engine that will power that opportunity.”

Zinio, self-dubbed “the world’s newsstand” launched their iPad app last Friday. The app enables iPad-owners to buy and read interactive full-color multimedia magazines. After purchase, the magazines can be shared on all sorts of devices. From your iPad to your iPhone to your desktop.

Zinio’s line up of magazines is impressive taking into account how early we still are in the digital magazine revolution. Zinio includes over 1,500 magazine titles like BusinessWeek, Cosmopolitan, Seventeen, National Geographic, Popular Science. In addition, it runs an adult publishing platform called UndercoverMags.com sporting the same technology and delivering titles like Penthouse, Playboy and Hustler.

A video of Zinio’s app on the iPad is shown below, although you’ll have to tilt your head to get the full experience:

Zinio is not the only one getting into digital magazine on the iPad. Major publisher Conde Nast of titles like WIRED previously reported to start publishing most of their titles on the iPad by the end of 2010.

Zinio is available now from Apple’s App Store.

Today, the Internet Movie Database or IMDb launched its IMDb Movies & TV app for the iPad in the App Store. IMDb is the most popular destination for movie related information on the web. It receives over 57 million unique visitors each month.

The IMDb app does exactly what it says on the tin: it makes all of the IMDb website’s information available in a special interface on the iPad. It also gives access to trailers and other movie related videos in high definition video. Apart from that, it can give you show times of your local cinema, TV listings and you can check out the latest box office results.

Nothing we couldn’t do on the IMDb website already, but hey, it makes the interface a bit easier to work with.

It’s now available from the App Store.
