The document discusses trends in managed content distribution moving from satellite-based to IP terrestrial distribution. Key points include adopting file-based workflows and IP distribution as satellite contribution is augmented by terrestrial IP. This allows for more cost-effective playback and collaboration without moving content. It also addresses the increasing requirements for handling multiple formats, partners, and time-based aggregation and distribution of live and on-demand video content.

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)

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

5.  Service Availability
Optimize Service Up time using network availability techniques
 Throughput
Design network with proper capacity for required traffic
Configure correct QoS for Video
 Delay/Jitter
Minimize end to end delay using QoS
Allocate sufficient jitter buffers at application layer
Minimize application layer jitter buffer size to improve channel
change time
 Loss
Minimize outage time to reduce packet loss

6. • Transport (Acquisition, Contribution and Primary Distribution)
Stadium to Production Studio
Studio to Studio
• IPTV (Secondary Distribution) / CATV
IP multicast distribution from centralized super headends
Driving enhanced multicast features and functions
• VoD (Secondary Distribution)
Distributed architecture for better scalability
Non-real-time content distribution to caches
More 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

7. • 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
