Rovi White Paper: The Cable Operator’s Guide to Migrating to IPTV

Posted on October 12, 2015

Today Rovi released a new white paper entitled “The Cable Operator’s Guide to Migrating from QAM to IPTV.” The publication addresses the problems posed by the limitations of MPEG-2/QAM-based infrastructures and outlines common IPTV migration strategies to consider.

With traditional MPEG-2/QAM-based models, cable operators push program information downstream to subscriber set-top boxes; this one-way information flow limits program choices to what fits in the content “pipe” into the home and does not support personalized experiences like those offered by streaming video services.

Conversely, Internet Protocol TV (IPTV) is a two-way system; content remains in the network and is only sent to customer homes upon request. It delivers TV services via an IP-based network, such as a LAN or the Internet, rather than through traditional satellite signal and cable TV formats, so media players can begin displaying content before the entire file has been transmitted. With IPTV, operators can provide a much broader range of content to consumers, including video on demand (VOD) and interactive TV (iTV), in addition to live TV.

The advantages of migrating to IPTV are numerous, as are the benefit for both operators and subscribers. But, while the need to migrate to IPTV is clear, the industry has yet to adopt one standard migration path. The Rovi white paper explores the pros and cons of three common migration strategies: unicast, multicast and hybrid. It also details business considerations and proposes next steps for operators looking to make the transition.
