By any analysis, today's pay television operators are facing a more competitive marketplace than ever before. Pure play over-the-top (OTT) providers have joined the traditional battle between cable, satellite and IPTV, creating more concern for legacy players.

This new competitive landscape for video services has increasingly meant delivering content in parallel over different networks to a wider variety of devices. With the latest technologies and protocols enabling OTT video, operators are now combining their proprietary delivery networks with wireless and the Internet for a more compelling consumer experience.

But these new offerings require more complex solutions for encoding, managing, and distributing content – and navigating the thorny arena of content rights on new types of devices that operate inside and outside of the subscriber's home. As early TV Everywhere ventures have illustrated, the challenges of acquisition and management of such rights should not be underestimated.

View the presentations from the Multi-network Solutions in the Real World Forum during NAB 2012. An expert panel presented the opportunities, challenges and solutions for commercial video delivery over combinations of managed and unmanaged networks.

  19. 19. Mobile Devices From walled gardens to open platforms  iOS, Android, etc. Screen resolutions getting higher  PD becoming irrelevant  Trend is towards treating everything like HD Pay TV “TV Everywhere” vs. OTT services  Licensors tend to require same levels of security for both  Yet market forces may cause them to differ #multinetwork #nabshow - 19
