- HDMI allows the availability
of a new mini connector for devices such as camcorders
- The availability of HDMI 1.3
depends on your specific equipment.
- All HDMI cables should be
made using the largest gauge (AWG) wire with individually
shielded pairs possible with top quality workmanship. This
protects your signal from Electromagnetic Interference (EMI)
and Radio Frequency Interference (RFI).
- Increases single-link
bandwidth to 340 MHz (10.2 Gbit/s)
- Optionally supports 30-bit,
36-bit, and 48-bit xvYCC with Deep Color or over one billion
colors, up from 24-bit sRGB or YCbCr in previous versions.
- Incorporates automatic audio
syncing (Audio video sync) capability.
- Optionally supports output
of Dolby TrueHD and DTS-HD Master Audio streams for external
decoding by AV receivers.[8] TrueHD and DTS-HD are lossless
audio codec formats used on Blu-ray Discs and HD DVDs. If
the disc player can decode these streams into uncompressed
audio, then HDMI 1.3 is not necessary, as all versions of
HDMI can transport uncompressed audio.
HISTORY:
HDMI 1.0
- Single-cable digital
audio/video connection with a maximum bitrate of 4.9 Gbit/s.
Supports up to 165Mpixels/s video (1080p60 Hz or UXGA) and
8-channel/192 kHz/24-bit audio.
HDMI 1.1
- Added support for DVD audio
HDMI 1.2
- Added support for One Bit
Audio, used on Super Audio CDs, up to 8 channels. Ability
for PC sources to use native RGB color-space while retaining
the option to support the YCbCr CE color space.
HDMI 1.3
- Increases single-link
bandwidth to 340 MHz (10.2 Gbit/s)
- Optionally supports 30-bit,
36-bit, and 48-bit xvYCC with Deep Color or over one billion
colors, up from 24-bit sRGB or YCbCr in previous versions.
- Incorporates automatic audio
syncing (lip sync) capability.
- Supports output of Dolby
TrueHD and DTS-HD Master Audio streams for external decoding
by AV receivers.
What does HDMI 1.3 do that
previous versions didn’t do?
HDMI 1.3a adds six benefits to the HDMI palette. The most
obvious and easiest to understand is higher data transfer speed.
The HDMI 1.3a standard increases single-link bandwidth to 340
MHz (10.2 Gbps), which will support demands of future HD display
devices incorporating higher resolutions, Deep Color and high
frame rates. Keep in mind that previous versions of HDMI are
fully capable of 1080p performance. Even more, the FCC has
presented no imminent plans for a “higher” high-definition
system than 1080p. Because 1080p has just begun to enter the
market this increased bandwidth can be considered more a hedge
against future applications than something the industry and
consumers can benefit from in the near future.
HDMI 1.3a also supports a format known as Deep Color. You may
see this referred to as Extended-gamut YCC (xvYCC). Deep Color
is a new color space used in video electronics. It can support
1.8 times as many colors as RGB. RGB, as you may know, creates
colors through a mixture of Red, Green, and Blue primary colors.
Deep Color defines colors by means of an algorithm that can
specify any color in nature.
This improvement in color performance is significant only in
specifications. Current HDTV broadcasts (and the current HDMI
standard) uses 8-bit color depth. The new HDMI 1.3a standard
with Deep Color capability expands the number of colors viewable
on an HDTV from millions to billions, while eliminating color
banding and subtle gradations between colors through the use of
10-bit, 12-bit, and 16-bit color depths. It is vitally important
to understand that every movie ever transferred to DVD or any
other digital format has been done using 8-bit color depth.
While the new Deep Color format could provide an improvement in
picture quality, there currently is no content (no movies, TV
shows or archived material) available that can be easily
trans-coded into the new system. With the existing issues of
Digital Rights Management (DRM) and High-bandwidth Digital
Content Protection (HDCP) just beginning to be worked out it is
highly unlikely that Hollywood and the entertainment industry
will rush to provide software that is a clone of the original
movie quality. The first place Deep Color is likely to be used
is in advanced gaming systems, but even that milestone seems
beyond the immediate future.
HDMI 1.3a incorporates automatic audio syncing (lip sync)
capability. This is a system that will automatically adjust for
the difference in electronic latency between the processing
circuits of the sound and image. This discrepancy sometimes
manifests itself as a slight delay in the sound compared to the
image.
HDMI 1.3a supports output of Dolby TrueHD and DTS-HD Master
Audio streams for external decoding by AV receivers. TrueHD and
DTS-HD are lossless audio codec formats used on HD DVDs and Blu-ray
Discs. If the disc player can decode these streams into
uncompressed audio, then HDMI 1.3 is not necessary, as all
versions of HDMI can transport uncompressed audio.
HDMI 1.3a provides for a new mini connector for devices such as
camcorders.
Which products use HDMI 1.3?
The Sony PlayStation 3 is the first product available on
consumer market that claims an HDMI 1.3a connection. Epson has
released the EMP-TW1000 as the first display supporting 30-bit
deep color, one of the benefits of HDMI 1.3a. There are no other
products currently on the market that offer HDMI 1.3a interface
capability. Several new products will likely be shown at the
2007 CES show, but it is likely to be several years before the
expanded capabilities of HDMI 1.3a trickle into mainstream
products.
