The ease with which consumers can nowwatch video on mobile devices has been a defining feature of wirelessnetworks since the advent of 4G, and this trend shows no signs of abatingthroughoutthe rest of this decadeinthe steady transition to 5G. Beyond this, standardisation efforts are buildingupon thesolidfoundations of5G while introducing entirely new capabilities, with thesixth generation, 6G,destinedto offer extreme performance and expanded coverage.The vision isbuilt on creating a seamless reality where the digital and physical worldsconverge,deliveringmuch faster, ubiquitous connectivity than ever before.Inconcert with advanced and more efficient video codecs, such as H.265/HEVCand H.266/VVC, this will provide new ways of meeting and interacting withpeople, novel possibilities to work from anywhere and entirely new ways toexperience video and entertainment. Commercial 6G services are projected to launch around 2030, with trialsbeginning as early as 2028 and initial proof-of-concept demonstrations takingplace even sooner.Meanwhile, 5G capabilities will continue to advance inparallel, ushering in the era of 5G Advanced networks. This evolution will serveas a crucial stepping stone toward the development of future networks. A surge in the rich data economy TV and video enterprises are focused on building a robust online revenue mix,embracing a data-first growth strategy. The increasedfocus of TV and videoenterprisestowards digital revenue streams is predominantly driven byconsumer preferencesforvideo-first experiences.Someexamples: 12x Increase in global dataacross the last decadeto 182 zettabytes. ➢In 2024, there were 5.52 billion internet users worldwide,covering68%of the global population.Of this total, 5.22 billion(or 64%)of theworld'spopulation were social media users,with an averageengagement timeof 12 hours 15 minutes per month.➢Media consumption andvideocallsnow happenroutinelyon mobilenetworksacross asmartphone installed base of4.8billionworldwide.➢Ease of communication and commerce via internet resultsin anaverage time spent online per userof6 hours 36 minutes,representinga 3% increase overthe lastdecade.
