2HD Content, DCMWG
- In February 2009 analog television broadcasting
in the US will give way to digital. For many
viewers / passengers, High Definition in16x9
aspect ratio content will become the preferred TV
viewing with new HD TVs and HD service. - When DTV happens, many of the viewers will switch
to16x9 aspect ratio and some form of digital
display resolution. (480P, 720P, 1080i, 1080P.
Near HD, HD, Full HD.....). - This is a little more than year from now and the
IFE industry and technical community should be
ready for and understand the implications.
- The IFE industry relies heavily on consumer
technology and consumer content that is changing
rapidly. The trend and technology advances will
be toward HD and its improvements.

5HD Content, DCMWG
- IFE industry and technical community should have
an HD digital content specification or guidelines
in place when we switch to DTV.
- All the stake holders including airlines, content
owners, content service providers and system
developers should participate in this activity to
revisit the existing specifications and make
changes to include HD.
- There are many content and display
resolutions.(240, 480i, 480P, 720P, 1080I,
1080P... SD, ED, Near HD, HD, Full HD.....). A
review of these resolutions and bit rates are in
order.
- For IFE the choices will be few due to system
limitations
6HD Trends
- The number of households around the world with
high-definition television (HDTV) will treble
over the next five years as viewers switch to its
clearer, more vivid picture, according to a
report by Informa Telecoms and Media. - The transition to HDTV has been called a landmark
move for the industry, similar to the shift from
black-and-white television to color. - The number of homes taking the product will jump
to 151 million worldwide by 2011 from 48 million
when an estimated 1.2 billion households had a
television. - The report said some 58 percent of HD homes were
currently found in the United States and 20
percent in Japan, with Britain,Canada, China and
Germany also high on the list.
7LCD Market
- LCD panel market for 2008 is likely to grow by
18 from 2007 to 447.7 million units. - LCD TV panel prices are predicted to drop by 4
to 11 from 2007 through 2008. - In 2008, LCD panel manufacturers' operating
profits are likely to improve compared to 2007. - Dec.11 2007 Displaybank
8WAEA SPECIFICATION 0403 and 0395
- Reviewing the 0395 and 0403 specifications-
- Neither specification deals with HD
- Both specifications have provisions for 16 x 9
aspect ratio - The highest resolution is 720 x 480 for both 4 x
3 and 16 x 9 aspect ratio - 16 x 9 display panel resolutions available for
IFE today are 400 x 234, 800 x 480 and 1366 x 768
pixels - Much of the IFE digital content resolution used
today is at 352 x 240
9HD for IFE Systems
- New IFE systems are 16 x 9 format with SD
displays in coach class and HD displays in upper
class. - The major system manufacturers have or will soon
support MPEG-4. This will enable higher
definition resolutions with the same file sizes
and bit rates as MPEG-2. - Hard drive advances have increased the number of
movies and short subjects and could include HD
content.
10DCMGW Goals for HD
- With the participation of all stake holders, the
0403 specification should be updated to include
HD. - Resulting in a specification that does not
increase the number of content formats. - A specification that leverages on consumer
technology and reuse of available content. - In earlier working group discussions separate
encodes are required for the different formats
and content quality. Explore encode or transcode
technology to achieve above goals.
11HD Discussion Points Define High Definition in
the context of IFE usage What is the
likelihood airlines will choose HD? Examine
the practicality of HD encoding and integration
from the perspective
of Labs (multiple codecs, transcoding
and conversions) Studios (content
availability, early window viability)
Hardware Companies (compatibility, overhead
vs. seatback, displays)
12Points to ponder about HD in IFE Can we
eventually agree on what it will be, avoiding the
Elephant Test? Is one solution to
simply not adopt HD at all?
