HDR Ultra-HDTV — Part 6 Ultra-HD sources

Ultra-HD sources currently include Ethernet rental/purchase services, Ethernet real-time streaming, and the Blu-ray disc.

Streaming services have a bandwidth issue. 25Mbps seems to be the download speed ‘sweet spot’ for Ultra-HD streaming. Yet the average consumer connection is only 15 Mbps.  Unlike streaming, download only services avoid the issue by storing the data to a media server device (hard drive with user interface) for later playback.  Blu-ray discs also avoid the issue.  Just buy or rent a disc.  Load disc in player.  Press play and view.

The initial Ultra-HD Blu-ray players and most TVs are limited to the HDR10 format. Many will soon offer Dolby Vision upgrades. They jury is still out on other formats.  Finally Ultra-HD broadcast is currently limited to DirectTV and Dishnet via a limited selection of channels.  Off-air terrestrial broadcasts do not yet exist.
