It has been a fitful slow burn for mobile video broadcast and multicast over the last two decades, but under 5G commercial, regulatory and technological forces have at last become aligned. The result is that 5G networks will gradually assume the mantle for delivery of public service broadcasting in place of traditional terrestrial transmission, often over the same repurposed spectrum. A key milestone in this journey is about to pass almost unnoticed with the freezing of coding protocols for 3GPP Release 17, which means that implementation work on devices and network structure can begin. Release 17 brings many advances, including sidelink expansion and additional support for non-terrestrial networks (NTNs), but for video the key step is standalone broadcast enhancements…
