23. Contribution Link Alternatives
• Contribution links do not necessarily need to rely on
DVB standards
• Contribution links do not always transmit live feeds
• Contribution links do not need to transmit MPEG
video
• The face of contribution is changing, data, 2-way
comms and file based transfer vs. real-time transfer
is changing the way broadcasters perceive
contribution

25. Contribution Over IP
CDM-625, CinC & Video
• FOX News is based in New York
• Desired a Fly-Away Terminal for Video Contribution
• Also wanted 2-way voice comms and interconnect
with FOX Intranet
• Test done between NYC hub and 1.4m
transportables
• 3 Independent Fly-Away terminals all running video,
voice and data over IP
• 2 Mbps contribution feed to Hub, 512 kbps Return
• Use of Carrier in Carrier for BW reduction

29. Video Distribution Methods
• MPEG Transport Stream over DVB-S
• MPEG Transport Stream over DVB-S2
• MPEG Transport Stream over non-DVB standards
• Standards based Encapsulation of IP video over
DVB-S / DVB-S2
• IP video over non-DVB standards

30. Live Video Distribution
• Most live video distribution is the distribution of
MPEG Transport Streams (MPEG-TS)
• MPEG-2 and MPEG-4 (H.264) are the most common
forms of compressed audio and video
• DVB-S and DVB-S2 are the most common methods
of transmitting MPEG compressed audio and video
over satellite

31. MPEG TS Over DVB-S
What’s the point: DVB-S was designed to send
individual MPEG Transport Stream Packets and wrap
each individually.
Each
MPEG TS
has it’s own
FEC frame
