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.
