Much has been said and written, including various articles by me, about ATSC 3.0 being IP-based rather than relying on transport stream as in ATSC 1 (A/53).
That is a reflection of a philosophical underpinning of the new standard that aligns next-gen television to the greatest degree possible with the rest of “digital media.” (It’s always kind of bugged me that there is a distinction made between TV and digital media, because TV was the original digital media. But that’s a discussion for a different time.)
The point is ATSC 3.0 will be able to leverage all manner of developments available to other digital media platforms that were off the table with the original DTV standard.
A case in point is HEVC or High Efficiency Video Coding. In fact, ATSC 3.0 will enable an even more powerful extension of the codec known as Scalable High Efficiency Coding. Sinclair Broadcast Group plans to leverage this extension in delivering content to mobile devices. (See: “Sinclair Free Chips Offer Key To Mobile Future.”)
The architects of ATSC 3.0 should see Apple’s announcement this week of HEVC support in macOS and iOS 11 as a strong affirmation that they are on track in aligning the next-gen TV standard with the digital media industry at large.
An article by Dan Rayburn at StreamingMediaBlog.com discusses the Apple move.
