Interesting. My bet is that this mysterious new Satellite and
Terrestrial Interaction Multimedia (STiMi) mobile TV broadcast standard
is something similar to satellite radio. Meaning, a robust satellite
link assisted by terrestrial translators. Still, to make the satellite
signal work with handheld device antennas must be a challenge.

China rolls two more mobile TV specs

SHANGHAI, China - A pair of Chinese mobile TV technologies are competing
for a shot to prove their worth at the 2008 Olympics at Beijing.
The competitors are Terrestrial-Mobile Multimedia Broadcasting (T-MMB),
a derivative of South Korea's Terrestrial-Digital Multimedia
Broadcasting, and STiMi, short for satellite and terrestrial interaction
multimedia.
Supported by academic-industrial coalitions in China, the mobile TV
technologies will compete with more established global standards being
tested in Chinese cities: Europe's DVB-Handheld and South Korea's T-DMB.
They will also compete against a handheld derivative of a
soon-to-be-approved terrestrial digital TV standard, known as DMB-T/H,
developed here.
Few technical details are available regarding the new technologies.
T-MMB was jointly developed by Beijing-based software firm Nufrontsoft,
the Communication University of China and Southeast University. It is
supposedly compatible with DAB-based T-DMB. The spec supports
frequencies from 30 MHz to 3 GHz and a prototype chip is ready, with
samples expected in 2007, a Nufrontsoft spokesperson said.
STiMi was developed by the Academy of Broadcast Science, part of a
government ministry that regulates broadcasting here. STiMi supports the
S- and UHF/VHF bands and will use both satellites and terrestrial relays
to implement coverage. Little more is known about the technology.
Chinese officials said they hope to finish trials with the new
technologies by the end of 2006, and move into commercial trials in 2007
so that the technologies could be ready for the 2008 Olympics.
With three mobile TV standards already competing for attention here,
adding two more to the mix is likely to lead to confusion, said Zhiqing
Wang, vice director of the Telecommunication Standard Academy at the
Ministry of Information Industry.
There is already disagreement in China over which mobile TV standard to
use, and over whether using broadcast or cellular networks would be
best. China also has a poor track record for getting standards to market
quickly, which could complicate making either of the technologies a
serious contender for widespread use by 2008.
