ATSC 3.0 Passes Key Test, But Is It Ready to Graduate?

摘要

When LG Electronics tested an end-to-end 4K broadcast using the next-gen ATSC 3.0 standard Feb. 23 in South Korea, it promised to be a signal moment in the progress of the world's first IP-based broadcast system. The test wouldn't be a repeat of the live 4K HDR broadcasts using ATSC 3.0 at January's CES. Those trial runs used pre-recorded material loaded directly to a transmitter. This time, the test would feature a live camera feed with real-time IP transmissions, involving Korean broadcasters SBS and MBC, broadcast equipment supplier TeamCast of France, video software supplier Media Excel of the U.S. and the Electronics and Telecommunications Research Institute (ETRI) of Korea. "It's a first, and it's a major step for ATSC 3.0," said LG spokesman John Taylor. "It shows the progress being made."
