Casa’s disruptive
technology unifies the functionalities for video-over-MPEG and
video-over-IP into a single platform at a cost level unimaginable with
previous technologies. This unification provides a single management
point for HFC spectrum resources for all digital services and a seamless
migration path from one architecture to another without costly fork-lift upgrades.
Casa Systems' products
provides all
the functional components needed in deploying digital broadcast, digital
simulcast, switched digital video, and unicast services.
Casa Systems’ first
line of products – the C2000 Digital Cable Termination Systems (DCTS) –
provides five categories of functionalities:
-
MPEG Edge-QAM:
The DCTS performs traditional edge functionalities such as conditional
access encryption and QAM modulation. However, the DCTS has dramatically
increased the density and reduced the cost compared to traditional
Edge-QAM.
-
Video-over-IP:
The Casa DCTS provides a flexible and complete DOCSIS 3.0 implementation at a
cost which will make video-over-IP an economically viable solution
today. The DCTS implements a hierarchical QoS scheme to allow sharing
of the RF spectrum between MPEG traffic and IP traffic with guaranteed
bandwidth and jitter.
-
Video Switching
and Grooming: The DCTS performs MPEG stream processing, MPEG switching and
multicasting to provide switched digital video services.
The statistical multiplexing capability also
makes it an ideal platform to groom VBR traffic for TV programs on
demand.
-
Transrating &
Statistical Multiplexing:
The DCTS offers
statistical multiplexing of VBR traffic and intelligent trans-rating.
This allows the operator to control the bit-rate change from input to
output to achieve optimal bandwidth utilization with minimal image
quality degradation and low latency.
-
Digital Program
Insertion:
The DCTS
provides standards-based splicing compatible with all leading digital
ad server offerings. Built-in high capacity switching provides
targeted local ad insertion in a much finer granularity than available
with other systems in its category, thus giving the service providers
added revenue generating capability.
