As the revenue composition of MSOs evolves into more IP-centric services, the cable
networks are also becoming more IP-centric. The video delivery network from
video servers to the network edge has already been converted to IP while the
edge device (Edge-QAM) is still native MPEG. The industry trend is to unify the
delivery of digital video and IP data into one edge platform based on IP. The
motivation is to simplify the network design, to reduce total capital expenditure,
to reduce network operational cost, to reduce set-top-box cost, and to offer
flexible services in a single platform. Casa products will completely change the
cost structure of video-over-IP.
