■ Domestic/Foreign Video Solution Market Trend

■ Domestic/Foreign Market TrendAs for domestic video solution market, starting with public offices in 2002,

nowadays many civil manufacturers have been emerged as major clients, which means the video solution market is now set on its way.

Increased usage of civil manufacturers is mainly due to the change of corporate management such as alliance with foreign partners, demand of quick decision making and plant construction in foreign countries. Besides manufacturing industry, financial sector is increasingly using it to meet client’s request for sharing information in real-time.

In case of desktop-based video and document conference market, in particular, it is expected that the local technology has high possibilities to be exported to foreign market conversely.

5. Video Chat

Obstacles of charging chatting sites Netizens’ reluctance to accept charging / Free contents providers still exist Lack of substantial experience and know-how of creating profits through the site Insufficient technical and systematic foundation in site management system, billing system, digital authorization

security, security, formatting, and relevant regulations

2004 200120012000 2002

Video chatting sites opened competitively

Free service provided for a certain period

Business worsened since they could not find proper income resource except ads and e-commerce.

Even those did not guarantee profitability.

Charging of video chatting & internet service sites emerged as a hot issue.

‘OhMylove’ and ‘eyemeeting’ : Flat-rate billing system

‘SeeNJoy’ : Charging by item and added function under process

Plan to activate charging chatting site (Top priority challenge – plan a site to persuade web users who will be charged) Minimize their resistance by applying such type like Premium Service Personalization : Need to figure out each user’s interest and their strong needs Need to use various licensing strategies : using authority for each function, period, usage limitation, licensing price

policy, etc. It would be better to evaluate the strategic incidental profits like ads, e-commerce, profits from contents sale rather

than direct profits through licensing itself. Billing policy : Pay-on-demand type is more desirable than flat-rate system (subscription).

Additional charging sites expected to appear

More complicatedness expected by diversified functions and items
