Samsung announced during CES 2015 is joining with several entities to create the UHD Alliance. The Alliance is made up of Hollywood studios, content distributors, and technology companies, and has a goal of establishing premium standards to be followed by both content and devices, particularly video content at 4K and higher.
From Samsung Tomorrow:
The UHD Alliance was created with the consumer in mind; it provides information on premium Ultra-HD content and devices to deliver best-in-class home entertainment. The Alliance is also focused on helping consumers benefit from a seamless, integrated and high-quality Ultra-HD ecosystem from end-to-end. Premium Ultra-HD content and devices will be clearly identified so consumers can easily recognize them in-store.
The UHD Alliance counts companies like DIRECTV, Dolby, and Netflix among their membership.
