Description
Advanced satellite channel modulation and video compression
technologies offer a quantum leap in efficiency that fuels structural
changes in satellite-delivered entertainment and connectivity across a
wide range of scenarios. Applications that benefit from advanced
modulation and/or video compression range from satellite
HDTV
distribution and contribution, to professional applications, to
satellite broadband, to the emergence of new "HITS" platforms, content
"push" and satellite backhaul.
DVB-S2 modulation and
MPEG4
AVC (H.264) video compression have been widely accepted as the
prevalent standardized means to optimize satellite links in video
broadcast and point-to-multipoint networks. However, despite wide
industry acceptance and validated bandwidth savings, questions remain
as to what speed will these technologies be deployed, where and how for
the relevant scenarios. Depending on application-specific
considerations, including installed base of legacy components, network
scale and new competing delivery models, the business case of deploying
MPEG4 and/or
DVB-S2 systems against matured MPEG2 and/or
DVB-S
can be challenged. Factors affecting migration include higher costs of
advanced set top boxes outweighing space segment savings,
region-specific satellite footprint characteristics preventing
efficiencies from features like advanced code modulation (ACM) from
realizing their full potential, local regulatory and completive issues
discouraging the emergence of new cable/telco distribution platforms,
and collective switching costs deterring or discouraging system
migration.
The drivers and specific contextual considerations for each of the
sub-sectors where advanced coding and modulation apply imply varying
degrees of adoption speed and tipping points for hardware suppliers,
operators and service providers to take into account when planning
deployments in both greenfield and replacement scenarios. HDTV is
clearly a strong driver toward the adoption of both DVB-S2 and MPEG4 in
some key markets, and the leadership position that companies like
DirecTV, BSkyB and EchoStar have taken on HDTV as an ARPU enhancer
against cable VOD has helped accelerate a virtuous cycle in hardware
development that stretches from semiconductor companies to equipment
vendors.
Future proofing considerations of these technologies also become vital
in the context of fast changing technology and increased diversity of
network environments with new ways to access media. This NSR report
analyzes the characteristics of each application, regional market
considerations and trends to identify greenfield deployments and
migration schedules for the implementation of DVB-S2 and MPEG4
satellite-based networks and systems
