proposal to replace HDMI is called Super MHL,
backed by Samsung, Sony, Toshiba, Nokia and chip-maker
Silicon Image. It¡¦s aimed at 8K video, a new
format not expected for several years that offers
pictures with 16 times the resolution of today¡¦s
best high-definition TV.
based on the MHL standard already in existence,
but one you¡¦ve probably not come across. MHL
sends video over the USB connector on a phone
to a flat-panel display. If the display also has
MHL support, a straight cable into the HDMI connector
is all that¡¦s required, but TVs without the standard
require a more expensive adapter.
compatible products first went on sale in February
2011, more than 750 million have been sold, according
to the MHL Consortium.
technology has advanced through several versions,
moving from conventional high-definition video
to 4K video, which is four times the resolution
of high-definition video. Each time it¡¦s been
upgraded, it¡¦s retained reliance on the HDMI
connector present on all TVs today, but that all
changes with Super MHL. The HDMI port can¡¦t carry
enough data or the accompanying multi-channel
audio for the sort of services envisaged with
8K broadcasting, thus the need for a new connector.
Super MHL plug is reversible and also supports
charging of mobile devices, so consumers will
be able to stream content from their phones while
the battery replenishes.
will be able to carry 8K video at up to 120 frames
per second¡Xtwice the number of images per second
of today¡¦s high definition, which should mean
fast-moving video appears smoother.
consumers still haven¡¦t moved beyond high-def,
but the electronics industry is always looking
for ways to sell more TVs, so there are already
plans to replace next-generation 4K with next-next-generation
the pack is NHK, Japan¡¦s public broadcaster,
which has been developing 8K for years and plans
to begin domestic broadcasts in time for the Tokyo
Olympics in 2020. NHK was the first broadcaster
in the world to begin regular high-definition
broadcasting when it launched a daily, hour-long
satellite service in 1989.
