Abstract
OpenCable is set of specifications created by CableLabs
to, “define the next-generation of advanced digital
cable-ready devices.” These devices support digital
cable services and systems with well-defined specifications
to allow interoperability and to promote competition
among system suppliers.
OpenCable specification (POD-Host) defines the subscriber
terminal equipment as consisting of a navigation device
(Settop box) and an external module called Point of
Deployment (POD). The Set Top Box (STB) consists of
the necessary electronics to transport and convert broadcast
signal from the plant facilities to the subscriber.
An intelligent “Host” inside the STB also
communicates with the plant facilities to direct and
steer the services. The POD is a detachable device,
which could be in the form of a PC card that plugs into
a PCMCIA slot on the STB. This POD module is a renewable
and replaceable device that addresses the issues of
Conditional Access/Security functions, as well as the
signaling functions. This whitepaper gives an overview
of the OpenCable Standards and Wipro’s expertise
on OpenCable STB.
