HDR Ultra-HDTV — Part 6 Ultra-HD sources (3/17)
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 on 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 the disc in the 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. The 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.
