Developments in Managed Content Distribution
The Shift from Satellite-based distribution to IP-terrestrial distribution

OTT & TV Everywhere Affecting Traditional Distribution Methods
• 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)

Trends Implications
• Adoption of file-based workflows.
• Migration from SD-HD-3D.
• Changing Distribution Patterns: Downloads, International Day/Date Releases, OTT, etc.
• Increasing amounts of B-B partners with different SLA requirements for content contribution, aggregation, and distribution.
• More digital media files being created while decreasing videotape usage.
• Individual file size increases requiring more storage and more network throughput.
• Multiple file types, unicast and multicast delivery requirements, automated “lights-out” aggregation and distribution.
• Hybrid transport handling and increased capabilities of Video over IP.

Video SLA Requirements
Service AvailabilityOptimize Service Up time using network availability techniques
ThroughputDesign network with proper capacity for required traffic
Configure correct QoS for Video
Delay/JitterMinimize end to end delay using QoS
Allocate sufficient jitter buffers at application layer
Minimize application layer jitter buffer size to improve channel change time
LossMinimize outage time to reduce packet loss

Terrestrial-Based IP SolutionsTypes of Video Services
• Transport (Acquisition, Contribution and Primary Distribution)Stadium to Production Studio
Studio to Studio
• IPTV (Secondary Distribution) / CATVIP multicast distribution from centralized super headendsDriving enhanced multicast features and functions
• VoD (Secondary Distribution)Distributed architecture for better scalabilityNon-real-time content distribution to cachesMore impact on metro and access networks, less impact on the core
• Over-the-Top (e.g., Hulu, Apple TV, Netflix)Adaptive streaming methods are quickly becoming ubiquitous

Satellite-Based IP Services
• Long-realized methodology for large scale multicast delivery requirements
• Most cost-effective multicast solution for compressed video for point to multi-point distribution
• System of choice for relaying real-time data / video / in “first-responder” situations
• Low cost receivers enable ubiquity and minimal costs for additional receive sites
• A virtually maintenance-free service
• Historically “five nines” (99.999%) reliability
