IP-enabled workflow advances set for NAB

IP transport will touch so many aspects of television that it is positioned over time to supplant most everything people know and understand about TV workflows.

The following is an excerpt of the original article from TVNewsCheck.com

Vizrt is a good example of a company that has one foot in the IP, file-based world and the other firmly planted in the baseband video world.

Most of what we do is an IP workflow already, at least before it goes out as an SDI signal or an IP stream, says Isaac Hersly, president Vizrt Americas.

All Viz Engines, the company's rendering processor and real-time graphics and video compositor, offer both SDI and IP output, he says.

Supporting an IP stream out of its products opens up new opportunities for broadcasters on several fronts. One example is the Viz Trio character generator, which integrates via an IP connection, not SDI, with the NewTek TriCaster video switcher, thereby freeing up an SDI input on the switcher that can be used for another camera source, Hersly says.

That graphics box is normally SDI, but because of the NewTek switcher accepting an IP stream, we are feeding two channels of graphics via IP to the switcher, he says.

Another is using the separate SDI and IP outputs from the Viz Engine to enable broadcasters to brand content flowing from the IP output as one version and that from the SDI as another.

So you get the same video coming into the box, yet the branding can be different for the SDI and IP streams. We see a lot of potential there and are already seeing some people using that type of operation, he says.

At NAB, Vizrt will be showing tight integration between its MAM systems from off-the-shelf to proprietary versions with Adobe Premiere, Hersly says. We will be able to move video and graphics to our engine, which will play it out as multiple streams from MAM to playout where graphics can be burned in or not. This gives us the flexibility to change graphics at the last minute, and allows us to change graphics but maintain metadata.
