It is curious to watch these discussions among highly educated and highly

times, the discussion often reveals a complete lack of understanding of the
consumer of what those on this list produce.
This has always been the tough part of technical marketing. That is,
understanding the ways in which technology can enable markets.
Mark Aitken asked: "Why is CBS (and dragging Sony & others) so
adamant about making sure 1080i is included in the upcoming h.265
spec? Is there more than religion at stake here?"
The simple answer is YES.
The MPEG-2 process was corrupted to protect the TV industry from "the
next Big Thing." In simple terms, one can define this as the
transformation of video from a a highly controlled analog medium,
into a form of data that can be managed and shared by the masses.
Interlace was a critical component of MPEG-2 (and then h.264) for
three reasons:
1. To protect the (primarily Japanese) investment in interlaced HDTV.
2. To recreate and extend the life of Intellectual Property related
to the use of interlace in the standard, and the downstream benefits
to the owners of this IP.
3. To preserve a perceived barrier to competition from the IT
industry, which identified interlace as a major barrier to the
"convergence" of television and computing.
My best guess is that CBS. Sony et al, are trying to get interlace
into h.265 for two reasons:
1. To participate in the patent pool;
2. To protect and extend the perceived life of 1080i acquisition and
production gear.
Leonard hit the nail on the head with respect to the vision thing.
By the time the U.S. HDTV standard was approved, any technologist
worth his or her salt knew that this standard would not be relevant
to the future of consumer electronics for very long. In essence the
CE industry was trying to manage the future based on a dying business
model rooted in scarcity and financial barriers; they incorrectly
believed that HDTV would dominate for several more decades.
Instead, a new CE industry has been created based upon easy access to
content anywhere, anytime.
