An alternative approach is the IPTV version of the Headend in the Sky cable TV solution. Here, multiple TV channels are distributed via satellite to the ISP or IPTV provider’s point of presence (POP) for IP-encapsulated distribution to individual subscribers as required by each subscriber.
This can provide a huge selection of channels to subscribers without overburdening Internet trunking to the POP, and enables a best IPTV in market as service to be offered to small or remote operators outside the reach of terrestrial high-speed broadband connection. An example is a network combining fibre and satellite distribution via an SES New Skies satellite of 95 channels to Latin America and the Caribbean, operated by IPTV Americas.
While the future development of IPTV probably lies with a number of coexisting architectures and implementations, it is clear[according to whom?] that broadcasting of high bandwidth applications such as IPTV is accomplished more efficiently and cost-effectively using satellite and it is predicted that the majority of global IPTV growth will be fuelled by hybrid networks.
The Internet protocol-based platform offers significant advantages, including the ability to integrate television with other IP-based services like high-speed Internet access and VoIP.
A switched IP network also allows for the delivery of significantly more content and functionality. In a typical TV or satellite network, using broadcast video technology, all the content constantly flows downstream to each customer, and the customer switches the content at the set-top box. The customer can select from as many choices as the telecoms, cable or satellite company can stuff into the “pipe” flowing into the home. A switched IP network works differently.
Content remains in the network, and only the content the customer selects is sent into the customer’s home. That frees up bandwidth, and the customer’s choice is less restricted by the size of the “pipe” into the home. This also implies that the customer’s privacy could be compromised to a greater extent than is possible with traditional TV or satellite networks. It may also provide a means to hack into, or at least disrupt (see Denial of service) the private network.
