Q: Would you please give us a brief
introduction to which areas are you involved in TD-SCDMA?
Dilithium Networks focuses upon 3G video.
Our core technologies are developed in accordance with 3G.324M standard, which supports video communication services over 3G networks. 3G.324M standard was developed by 3GPP and 3GPP2
for video services and was adopted by TD-SCDMA for video services. In
the past few years, we mainly focused on WCDMA. Our major products and
technologies include: first, 3G.324M protocol
stack software for the development of video-enabled mobile handsets;
second, Dilithium Networks Analyzer (DNA) for the development of mobile
handsets and network video equipment. It can be used to analyze and
test 3G.324M equipment, such as conformance testing and interoperability
testing; third, DTG2000, a transcoding multimedia gateway. It supports
the communications over 3G mobile
terminals and IP video terminals, and the application of video contents.
Over two years ago, our team in North Asia and greater China region
started to report the development of TD-SCDMA to our headquarters. For
instance, we have invited our CEO to visit Datang Mobile, China Academy
of Telecommunications Research (CATR) and TD-SCDMA Alliance and meet
the leaders to know the development of this standard, of which Chinese
enterprises hold significant IPRs. Through these activities, our senior
management acquired a good understanding of TD-SCDMA business. With
the support of the headquarters, we provided protocol stack software
and testing analyzers for Datang Mobile to jointly develop the first
TD-SCDMA video handset. Several months later or in mid 2004, Datang
demonstrated this handset to the leaders of the Ministry of Information
Industry (MII), showing that TD-SCDMA video handset can have the same
functions as WCDMA video handset.
Q: What are the differences with video
application in WCDMA, CDMA200 and TD-SCDMA?
A: With regard to the quality of WCDMA and TD-SCDMA
video services, I think that they can reach the same level from the
technological perspective, including video quality on terminals. However,
at present there is a small range of TD-SCDMA handsets available. When
TD-SCDMA video handsets get more mature, I believe the difference of
video effects will disappear. At present the application of video services
in TD-SCDMA and WCDMA networks is the same, including the application
in both CS and PS domains while the video application in CDMA2000 networks
is mainly in PS domain. As for the CS-based application in CDMA2000
networks, we have to wait and see its further development.
Q: As we know, Dilithium Networks has
the experience in developing video services for both TD-SCDMA and WCDMA
networks. Could you compare their pros and cons?
A: Our video technologies are widely applied in WCDMA
networks. For example, Qualcomm¡¯s 6250 chip solutions are widely adopted
by many manufacturers as the platform to develop WCDMA handsets.
Q: Could you specify which companies
adopted video telephone technologies developed by Dilithium Networks?
A: In the area of TD-SCDMA, I can only specify the
name of one company, Datang, our major partner in developing mobile
handsets. When the time comes, I can tell you the names of other partners.
Q: Do you think that video services
developed by your company can pass the TD-SCDMA testing?
A: At present, the testing is focused upon basic
networks. There are also some demos and testing on gateway application.
It is expected the next-phase systematic testing will be organized by
CATR and TD-SCDMA Alliance. We have demonstrated our video application
in WCDMA and TD-SCDMA trial networks to the leaders and operators.
Q: Could you give us a brief introduction
to AnswerFast Plus technology?
A: This technology is mainly used in handsets and
gateways to shorten call setup time and improve the experience of end
users in the process of video call so that the users may have similar
experience as 2G handsets in terms of call setup time. For detailed information,
you may visit our website. For specific project, you may also contact
our team.
Q: Can your technology be applied in
on-line gaming over mobile handsets?
A: With respect to on-line gaming over mobile handsets,
I can say that if the games are CS-based, they are the same as ordinary
video communication and if they are PS-based, 3G terminals are capable
of supporting on-line gaming.
Q: Could you tell us a little about
your DNA?
A: For detailed information of our DNA, you may visit
our website for product description or provide your e-mail address to
the TD-SCDMA Forum, through which we can e-mail product description
to you.
Q: Have you ever contacted any operator?
A: As a matter of fact, we had very frequent communications
with operators. The R&D center of China Mobile has adopted our DNA
to test 3G video services. In the application front, our communication
with operators has never stopped. In 2006, we will demonstrate new services
and application to the leaders and planners of market operation of telecom
operators through our demo system so that they could make a decision
based upon practical trials, experience and judgment.
Q: Is Ericsson your competitor? How
do you view your competitors?
A: This question is about the competitive and cooperative
relationship in the field of TD-SCDMA. First, I believe that competition
is a driving force behind technological progress and quality improvement.
If there are many vendors participating in the competition for the development
and application of TD-SCDMA products, it¡¯s good for the development
of this industry. But operators have the final say whether to select
which equipment and technology. Of course, they will choose the system
and products with better quality and performance for commercial services.
Q: What is the prospect of video communication
over mobile handsets in China? What challenges it will face?
A: This is a very important issue concerning the
development of 3G video services. In light of the development of WCDMA over
the past few years, there are a lot we have to improve. But the industry
has reached broad consensus. I¡¯d like to give you some examples. First,
many friends have noticed that what really matters is what the habits
of end users using 3G video
handsets are and for what types of communications they will use video
communications. Many users feel that video communication is not suitable
for work, but for the communication between family members and friends.
For instance, you are on a business trip, you may have video communication
with your parents and children. This is considered as a suitable communication
form. It can also be used in information services and entertainment.
Take Beijing Olympic Games as an example. It is a grand event attracting
the attention of all Chinese and the people in the world. The 3G video terminal will become a very important personal information
media. During the Olympic Games, the results of matches and races will
be a great focus. The information can be delivered to different terminals
through different media. If you wish to watch a complete soccer match
live, TV is probably the best media. But there are people who cannot
stay beside TV for various reasons such as working, but have a strong
desire to catch up with the development of matches. For instance, some
wish to know whether Liu Xiang wins the gold medal immediately after
the match is over. Others wish to watch the match from the very beginning
through different media. For one match, there are two types of demands:
knowing the results and knowing the process. The first type of demand
can be fed through SMS or MMS with the supplementation of streaming
media rebroadcast or clips. The 2nd type of demand can be
met through 3G video terminals. 3G subscribers can access
the portal of mobile operators anytime anywhere to watch the whole process
of 110m-hurdle
race. These examples show that we must adopt market segmentation methods
to design suitable 3G video services while developing
3G video
application. Looking into the future, we feel that TV, plane media,
Internet, and personal mobile terminals, especially 3G multimedia terminals will form a complementary and integrated system
of personal communication, information and entertainment to meet different
needs of different people for communications at different time and places
and on different occasions. 3G handheld terminals can meet the needs for communication
anytime anywhere. They are personalized terminals, unparalleled by other
terminals. They enjoy huge potentials for further development. From
the perspective of China¡¯s 3G operators, 2008 marks the beginning of a new communication era
to provide Olympic information for 3G video subscribers through various means (SMS, MMS, live
broadcast, streaming media rebroadcast, web page browsing, etc) on the
mobile communications networks. If 3G is launched timely, China¡¯s 3G services and application will take the lead in the international
arena after 2008 Beijing Olympic Games. The success of SMS is a typical
example. When the Spring Festival comes, we all send SMS to pay a new
year call to our friends, families and workmates. From the eve to the
first day of Spring Festival, SMS has become a successful service in
the communication sector. From the marketing perspective, the success
of SMS is a combination of text message with the tradition of the Chinese
people to pay new year calls.
Q: Would you please predict which 3G application will succeed?
A: According to the feedback we got from the market,
we feel that video application for the communications between family
members or friends will enjoy a huge potential of growth. As for video
communications and entertainment, I¡¯ve already given you the example
of the Olympic Games. I think they will have their chances of success.
Q: For the industry and users, they
are concerned of whether major 3G standards can be unified or there will be problems with
the communications between these standards. What do you think about
that?
A: This question concerns the convergence of 2G and 3G, including
the convergence of broadband services over 3G networks and IP networks. It is a process of service and
application expansion. 3G networks will have to offer services already delivered by 2G and GPRS networks, such
as SMS, MMS, color ring back tone, voice mailbox. New services with
video as the core will be added, including video call from mobile terminals
to video terminals, multi-party video telephone conference on mobile
terminals and IP video terminals, video mailbox, video color ring back
tone, and live information services in CS domain and PS domain, such
as the Olympic broadcast, family security system, monitoring of elders¡¯
residence.
We believe that there is no problem with the interconnection
between TD-SCDMA and WCDMA networks. Video communication is possible
not only between TD-SCDMA subscribers but also between TD-SCDMA and
WCDMA subscribers. Transnational communication will also be available.
With respect to the interconnection between major 3G standards, there is not
problem with the interconnection of voice and video services from the
perspective of technical standards. We participated in the TD-SCDMA
development and we provided DNA, one of whose functions is the interconnection
of videophone between TD-SCDMA subscribers, between WCDMA subscribers,
or between TD-SCDMA and WCDMA subscribers.
Q: Most of 3G handsets in the market
are WCDMA handsets. It¡¯s rare to see TD-SCDMA handsets. As a consumer
greatly concerned of China¡¯s 3G industry, what I care is the interconnection issue.
A: Actually many chip makers and handset manufacturers
are developing TD-SCDMA video handsets. I believe there will be more
types of TD-SCDMA handsets available in the market very soon. A major
decision that will affect the development of TD-SCDMA industry is to
provide sufficient types of TD-SCDMA video handsets for Chinese consumers.
As far as we know, not only major Chinese manufacturers but also well-known
international handset manufacturers are developing TD-SCDMA video handsets.
As the commercialization of TD-SCDMA approaches, we believe that the
development of TD-SCDMA video handsets will speed up with the joint
efforts of both domestic and international manufacturers.
Q: Most of 3G operators do not perform
well and data business is so not hot as expected. So how do you think
about that?
A: Looking back upon the development of 3G in the
past few years, we can say that Japanese and European operators took
the lead. There are also some new operators coming in. When 3G networks were rolled out in some countries and regions,
the operators met some challenges in introducing attractive services
and application that can generate satisfactory economic returns. Through
our discussion with operators and equipment vendors and based upon our
consumer analysis, I feel that the consensus we reached is that 3G multimedia communication
network and personalized terminals will bring about more and better
multimedia communication forms in the new era. However, different countries
and regions have different cultures, living habits, and ways of communication.
Therefore, demands for multimedia communications are diversified and
differentiated. Take SMS and voice mailbox as an example. In North American
and European markets, voice mailbox generated considerable revenues
and profits for operators. while in China and other Asian regions, voice
mailbox is less used while SMS is every popular. Therefore, we feel
that the primary task in the process of deploying 3G in China is to explore and develop services and application suited
for Chinese subscribers. This needs the early participation of marketing
and planning teams of operators.
Q: What is the status quo of mobile
video application in foreign countries? One short question, how can
we walk safely while watching TV or having a video call?
A: We believe that this year and next year will embrace
a new round of investment. Many WCDMA operators that have constructed
3G networks start to make more input to develop new services including
video services. if you follow the market trend closely, you may find
that there will be more and more services to be introduced to end-users.
With regard to watching TV on 3G handsets,
there is a lot discussion going on. What is worth mentioning is that
whether 3G video terminals are suitable
for watching TV programs for a long period of time. We think 3G video terminals are communications
tools that have multimedia functions. It may not be suitable for watching
long TV programs. Take the Olympic Games as an example. 3G terminals may not be suitable for watching
soccer match, which is long and big. But such terminals are suitable
for watching short TV live program such as track and field events like
110m hurdle race. The demand
of customers and application types can be categorized according to the
analysis of market segmentation. While using video communications, we
think consumers should not be driving or walking. One should take a
responsible attitude for his or her personal safety.
Q: In China¡¯s 3G market, which standard
will be the winner? Will CDMA2000 be marginalized in China?
A: China is a huge country. There are sufficient
customer bases to support services over different 3G networks.
We think that the success is determined by whether you have cost-effective
and attractive application. With regard to the tariff issue, I think
TD-SCDMA operators should work out their operation strategies based
upon sufficient market analysis.
Q: How do you think the timing of issuing
3G licenses in China?
A: As for 3G licenses, the Chinese
leaders have announced to the whole world that china will provide 3G communications services for the Olympic
Games. I think this is a positive indication. From now on, I think it
is still feasible to construct 3G communications networks. Even if Beijing and coastal regions are
covered at the initial stage, it will also be a good start for the development
of 3G communications
in China.
Q: What are the immaturities of TD-SCDMA?
A: Your question is about the technological maturity
of TD-SCDMA. We are convinced that through the testing and improvement
one round after another TD-SCDMA will become mature quickly. In my view,
the challenge the whole industry faces is that handset manufacturers
have to develop more types of TD-SCDMA multimedia terminals in a relatively
short period of time. You know timing is very important.
Q: If TD-SCDMA is commercially deployed,
what will be your focus?
A: If TD-SCDMA is commercially deployed, we, as a
participant in the TD-SCDMA undertaking, will focus upon developing
various good application and services in collaboration with the vendors
in the TD-SCDMA Forum. Just now, we talked of the Olympic Games. I¡¯d
like to say that it is our wish to make good application ready and provide
better information services for TD-SCDMA subscribers before the Olympic
Games comes.
Q: Do TD-SCDMA multimedia terminals
have to be smartphones?
A: No matter TD-SCDMA or WCDMA, there are several
types of terminals. There are low-end video-enabled ordinary handsets,
which are cheap. There are also middle-end and high-end terminals, including
smart phone, PDA and pocket PC. The middle-end and high-end WCDMA terminals
have been released in the market, some of which adopted WinCE operating
system and some of which adopted protocol stack software of our company
to develop handsets in collaboration with experts from our company.
