Building a Profitable Telco Video OperationThis paper offers headend and network design recommendations for both large and small Telco operators to leverage their core competency and build a profitable video operation. More...
Digital Simulcast Transition to the All-Digital Network This paper proposes that digital simulcasting, in which basic and enhanced basic programming are carried both in analog and in digital, provides a smoother migration towards all-digital cable by allowing a gradual swap-out of analog devices, rather than a singular transition. More...
Optimizing Bandwidth Efficiency through Intelligent Channel Multiplex Definitions Newly emerging tools perform sophisticated technical and statistical analysis of multiple program stream characteristics for the most intelligent multiplexes. More...
All-Digital: Whether and How to Get There This paper describes how "all-digital networks" initiatives can free abundant bandwidth to support hundreds of additional TV channels, faster Internet service and more rapid launches and scaling of advanced video services such as video on-demand and high definition. More...
The Triple-Play Network Platform This paper proposes the emergence of a new triple-play platform that consolidates all processing and communications functionality required for video, voice and data services, by combining the best elements of headend video services platforms and DOCSIS cable modem termination systems (CMTSs). More...
Seamless, Scalable HDTV Roll-Outs Over Today's HeadendsThis paper describes a comprehensive way to roll out full HDTV experiences in existing headends, suggesting among other things channel line-up scenarios that achieve bandwidth efficiency with high quality content through advanced video bit rate adaptation techniques. More...
Network Design for a Multiplicity of Services There is an increasing realization of the cable plant as an integrated multi-service and multimedia infrastructure. This paper explains how it is key to evolve the network from a collection of isolated silos supporting particular services, towards more inherent fitness for multiple services and media. More...
