    "abstract": "Ultrahigh-definition (UHD) delivery over terrestrial networks is a challenge in countries where there is no dedicated spectrum allocated for it. In an environment where UHD has to be simulcast with existing standard-definition (SD) and high-definition (HD), only a limited number of channels can be broadcast in UHD. In some cases, instead of a allocated spectrum for a 24/7 UHD broadcast, only a part-time channel through a time slot system is available. With the advance of low-latency scheme for over the top (OTT), it is now possible to mix and match broadcast and OTT without a noticeable difference in delay between the two delivery mechanisms. Broadcasters can offer a UHD experience 24/7 using other delivery channels for UHD, while HD (1080p60) is transmitted over the air (OTA). This paper examines OTT UHD delivery and assesses which solution is the best from a technical and financial point of view.",
