H.264 is perhaps best known as being the most commonly used video encoding format on [[Blu-ray Disc]]s. It is also widely used by streaming Internet sources, such as videos from [[Netflix]], [[Hulu]], [[Amazon Prime Video]], [[Vimeo]], [[YouTube]], and the [[iTunes Store]], Web software such as the [[Adobe Flash Player]] and [[Microsoft Silverlight]], and also various [[HDTV]] broadcasts over terrestrial ([[Advanced Television Systems Committee standards|ATSC]], [[ISDB-T]], [[DVB-T]] or [[DVB-T2]]), cable ([[DVB-C]]), and satellite ([[DVB-S]] and [[DVB-S2]]) systems.

H.264 is restricted by [[patent]]s owned by various parties. A license covering most (but not all{{cn|date=February 2024}}) patents essential to H.264 is administered by a [[patent pool]] formerly administered by [[MPEG LA]]. Via Licensing Corp acquired MPEG LA in April 2023 and formed a new patent pool administration company called [[Via-LA|Via Licensing Alliance]].<ref>{{citation |url=https://www.streamingmedia.com/Articles/ReadArticle.aspx?ArticleID=158547 |title=Via LA’s Heath Hoglund Talks MPEG LA/Via Licensing Patent Pool Merger |first=Jan |last=Ozer |date=2023-05-08 |publisher=StreamingMedia.com}}</ref>. The commercial use of patented H.264 technologies requires the payment of royalties to Via and other patent owners. MPEG LA has allowed the free use of H.264 technologies for streaming Internet video that is free to end users, and [[Cisco Systems]] paid royalties to MPEG LA on behalf of the users of binaries for its [[Open-source software|open source]] H.264 encoder [[openH264]].
