However, the need to install and maintain multiple TV devices is exactly the case where a solution based on a dedicated IPTV set-top box might prove to be the better choice. The main reason for this is that the IPTV field is still rapidly evolving and more and more IPTV content sources are becoming available. Since virtually every smart TV manufacturer deploys its own IPTV solution, which limits the availability of IPTV content from the outset, there is a high probability that the integrated IPTV functions of a given smart TV device will be completely obsolete before its life cycle of eight to ten years is over. This leads to replacement costs that can be considerable, e.g., in hotels with several TV devices.
