Digital audio and video industry is predicted to replace
communications industry as the first backbone industry in
Chinese national economy by 2010. As a basic standard with
much impact on digital audio and video industry, AVS
presents a rare opportunity for China to establish an
industrial chain: Technology ¡úPatents ¡úStandards ¡úChips and
Software ¡úMachine and System manufacturing ¡úDigital media
operating and Cultural industries.
For DTV receiver manufacturers, it is not difficult to adopt
AVS. For a standard, what matters most in physical
implementation is by a decoder chip. A DTV receiver can
support verified source code standards just by changing
decoder chips. Therefore, the cost of AVS replacement is not
as high as imagined.
AVS means much for digital TV operators. Digital television
operating system is made up of three main parts: program
producing, broadcast and transmission. Of the three, program
producing (executed in TV studio) and transmission (by
digital television transmission network) account for most
majority of the total input, but have nothing to do with
broadcast format, so the replacement with AVS does not
affect those already inputted efforts in the two links.
Using AVS requires fix AVS coders, but the effort will
certainly be rewarding. It can save at least half of the
transmission bandwidth resources and provide HD business to
transmission system deployed for SDTV, and as a result for
television network, transmitted program capacity will be
doubled. It benefits the state-owned resources as well,
because half of the wireless spectrum resources can be saved
in terrestrial broadcasting.
China is developing native CD-ROM and CD-ROM technology &
standards. The red optical disc servo system is practicable,
but it needs three or even more discs to store an MPEG-2
encoded high-definition movie. AVS coding efficiency is
three times that of MPEG-2 in compressing high-definition
programs, so one AVS-based disc will be large enough. When
it comes to film sources, program producers hope discs
issued in different regions in different formats. To publish
AVS format CD-ROM in Chinese market will facilitate the
healthy development of Chinese audio and video distribution
industry and high-definition optical disk driver industry as
AVS industrialization work has commenced since standards
drafting. It is now in start-up period for large-scale
The main applications for AVS include but not limited to the
1) Chips, HD /SD encoding and decoding chips, Chinese annual
demand in the next 10 years will reach an average of over
2) Software, program production and management systems, AVS-based
stream media broadcast, on demand, playback software on
Linux and Window platforms.
3) Machines, set-top boxes, hard broadcast servers,
encoders, AVS HD DVD, high-definition DTV set-top boxes and
receivers, Mobile, AVS portable digital devices and etc.
In short, the direct result of AVS industrialization are
China¡¯s demand for 300-500 million decoder chips in the next
10 years, to save more than 1 billion US dollars of patent
fees, directly provide high-definition operations by making
use of SDTV transmission system and create a new generation
of HD DVD on the basis of the current optical disc
technology. Therefore, it presents a rare opportunity for
China¡¯s digital AV industry to develop by leaps and bounds.
AVS is to usher in a bright future in cooperation with
powerful manufacturers of chips, software, machine and media
operation in the field of home appliances, IT, broadcasting,
telecommunications, audio, and etc.
