through a dedicated portion of the operator’s broadband spectrum.The article also mentions how Virgin intend to become a customer of the proposed Fujitsu-built fibre network, which would allow Virgin to expand their cable network, "across a further 20 percent of UK homes initially, with the help of its TiVo box, in effect as a hybrid IPTV/OTT provider outside its footprint."
In the case of cable TV, this is over DOCSIS and ensures that the TV service is independent of broadband Internet activity, making it easier to ensure high QoS. In effect, this makes it a walled-garden IPTV service, but it also brings genuine over-the-top (OTT) Internet content to subscribers. In the latter case, QoS is largely beyond the control of the operator at present and is dependent both on the wider Internet and on the third-party content providers themselves.
For the Virgin Media TiVo subscribers, all content is delivered via the TiVo box, including scheduled services. TiVo has therefore had to adapt the box to integrate with both Internet content and Virgin Media’s own catch-up service with the normal linear broadcast schedule. This was a challenge for TiVo because it has not so far had to integrate catch-up services to the same extent for its existing U.S. customers.
