- 2. • New Business Models and “TV Everywhere” (TVE) initiatives requiring more flexibility from the infrastructure. • Multiple formats, increasing aggregation and distribution partners, and the element of time are major obstacles to overcome. • Satellite-based IP contribution and distribution being augmented by terrestrial IP contribution and distribution systems for both Live and Non-Live content. • Pricing of terrestrial 10Gb/sec links between two locations ~$4K/month seen as an enabling factor for Video over IP and file-based movement. Further, playback of video over the IP network for collaboration / review / approve without moving content will become standard practice. • Seen as an economical alternative to leased HD-SDI lines. • Three main areas for investigation: Satellite-based contribution and distribution Software-based aggregation / distribution Video-Optimized Transport (Video over IP) © 2010 Cisco and/or its affiliates.

- Developments in Managed Content Distribution: The shift from satellite-based IP distribution to IP-terrestrial distribution. The continued growth of content consumption across an ever-increasing range of devices has created the need for multiple media formats and has also created new demands for content distribution methodologies. Satellite-based IP delivery has traditionally focused on the one-to-many multicast requirements and typically for linear content. However, hybrid methods of terrestrial IP distribution for both linear and nonlinear content delivery and consumption are increasingly being employed and implemented. This Cisco Knowledge Network segment will explore this shift in managed content distribution models and Cisco’s Video Optimized Transport solutions.
