1.2.1.2 Application #2: Disaster Recovery

Many operat

ors run disaster recovery sites in case some localized issue (flooding,

fire damage, power loss, adverse weather, etc.) prevents the main head-end from

working. Disaster recovery sites therefore exist to temporarily take over from the

main site.

Such sites are run to a budget, because it does not make sense to replicate an

expensive, premium head-end if the back-up head-end is only for occasional,

temporary use. Hence space is at a premium (real-estate being a key method to

reduce costs), and the need for premium picture quality is also reduced if this is a

route for cost reduction.

In such applications, the SPR1100 is a perfect offering. It can cover the entire

channel line-up in only a few chassis, and offers very low cost per channel pricing.

1.2.1.3 Application #3: New Services

Operators are always looking to dep

loy new value-added services in order to reduce

user churn and remain competitive. However, such new services need to fit into

existing head-end real-estate and, as ever more services are added, space

becomes a constraining factor.

The next service launch operators are targeting is catch-up TV, in which channels

are encoded differently to the linear channel ready for recording. For example, in a

cable system, linear channels might all be encoded using MPEG-2 for backward

compatibility with old boxes. The catch-up service, however, can be targeted only at

newer H264-capable boxes, and hence can take advantage of the better bit rate

efficiency of H264.
