iTX On-Demand
Automated VOD Asset Preparation and Publishing

iTX On-Demand specifically addresses the preparation of VOD and Catch-Up TV assets in a way that dramatically reduces operational costs and the time it takes to get content onto VOD platforms, for both pre-recorded and live content. iTX On-Demand automates the VOD process. It’s not a separate, or downstream, process — VOD asset creation is embedded into the production from the start, using powerful recipes that take the pain out of complex workflows making them easy to execute.
