2.2.2.2.2222.2.2.2.2 HighHighHighHigh FluidityFluidityFluidityFluidity

This system, processing the world’s leading original data transmission of high performance and the

strategy of notes distribution, integrates with HTTP, TCP, UDP(SUDP 、 RUDP), gateway penetration

module (UDP, RPNP) and IP chart of the whole world. These make the rate of nodes connection come up

to over 95% high. The super-high rate of data sending and receiving and large quantity of stand-alone

connections greatly ensures the quality of video playing under varieties of articulation.

Meanwhile, the design of this system has added the function of short connection hold under the

circumstance of disconnection and outbreak of unexpected network flow and it has optimized the strategy




of nodes distribution. Thus, no matter what kind of strike it suffers, the stable and smooth video watching

will be presented to audience eyes. In addition, considering the loading capacity of server it employs the

super-small bite stream that will not cause to much loads.

2.2.32.2.32.2.32.2.3 HDHDHDHD

The system supports various of stream protocols and code including streams like HTTP TS, UDP TS,

RTMP, MMS, MMS Over HTTP, etc. plus WMV9 ,H264,and VC-1 coding when live broadcasting. It can

use HD, SD data rate to achieve the broadcasting effect. What’s more, there are WME9, WMS, VLC,

FMLE, FMS, VJDirector, VJEncoder stream of push-and-pull for encoding software.

When using virtual file to broadcast, it can simulate the broadcasting system of TV station to realize

the function of hard disk broadcasting system with the help of playlist that produced by stream or HD

video file. Among the formats of HD video, there are wmv/asf/wma/mp3/rm/rmvb/flv, etc.

2.2.42.2.42.2.42.2.4 StartStartStartStart QuicklyQuicklyQuicklyQuickly

Considering that most broadcasting system which supports P2P start slowly, this system reaches

the starting speed of video that playing at once when clicking playing button by means of HTTP, optimized

code module, strategy of cluster links.

VJMS adopts the strategy of dynamic nodes adjustment like IP chart of the whole world and of the

region of operators. Gateway penetration of each level and gateway mapping of internal and external

network are supported. Also, it employs UDP and TCP self-adaptive mechanism for transmission which

can automatically switch to TCP to transmit when the UDP is not available. This ensures the connectivity.

For the complicated internal network environment like VPN, this system can map the port for

adjusting automatically in order to deploy in the Intranet with complex firewall and gateway. For

trans-gateway watching, it can use multiple protocols to penetrate nodes and connect them. It is easy for

different operators and transnational spots to arrange.

Thus, the operators can set up a series of live broadcasting system of fluent playing effect without

professional experience and purchasing of bandwidth.

CDN, also known as edging network is the network architecture that let more than one server to assist

each other to serve for millions of people.

Besides P2P, VJMS also offers CDN support procedure which can use various of live broadcasting

server (It can be set up separately in different regions, computer rooms of operators and this is called

mirror server)to mirror each other to realize broadcasting in super-large scale. So, its performance totally

superior to P2P.

For watchers, it can autosave the video segments which have been watched already for P2P sharing

via cache settings in order to relieve the stress of bandwidth of operators.

For operators, CDN automated storage means it needs to set up one central video resources pool

which other broadcasting servers download popular video files from according to hits and then carries out

P2P distribution.

This system employs the world’s leading P2P model of tree-net joint with net connection of high

penetrability that has greatly solved the problem about bandwidth consumption of server. What’s more,

two watching nodes are enough to save the bandwidth resources. The economy rate of bandwidth can reach

to over 90% if few people are using . When there are numerous users it will reach up to 95% that really

reduces the cost of bandwidth a lot.

The statistics conditions of reference data shown as below: vH264 code ， 400kbps data rate for

broadcasting. The sever is located in the room of ChungHwa Telecom, Taiwan. 1 hour later after starting

VJLive, the data collection begin. The data sampled for 3 hours every 10 minute are shown as below:

First, it can make the server disconnect from users and ensures a smooth process for watching at the




same time owning to the strategy of intelligent flow distribution. Second, it adopts the technique of short

byte connection hold that can greatly increase the number of users which a single server can carry.

According to the practical statistics results, the capacity of a single server has increased many times more

than the non-P2P one that can reduce the cost of hardware a lot for operators. Third, it uses the the CDN

structure so as to increases that number to a greater extend when the number of servers rises.

For computer-watcher (the specification about some terminals like mobile, STB will follow), VJMS

provides various modules of players that lower the dependency on plugins. This is different from P2P

system which must be equipped with webpage-plugins player. These plugins contains:

[standard P2P webpage-plugins]

——It requires users to install the traditional webpage-plugins player for only one time.

[FLASH player+ backstage P2P accelerator]

——In this mode，FLASH player is the defaulted item and users have an alternative download of a

backstage P2P acceleration program. Then the P2P mode will begin.




The superiority of this mode:

A. Operators can create a flash-based player and add functions in it.

B. The FLASH player can be used without compulsive demand for downloading any plugins,

software.

C. Flexible backstage P2P accelerator. You can choose to close or open the P2P function.

D. It is convenient for those websites which have used FLASH player before to transform into P2P

mode.

[shift between FLASH and standard P2P webpage-plugins]

—— Operators offers FLASH player and P2P webpage-plugins at one time for watchers to shift

between.


A. The articulation of videos displayed by FLASH player and P2P webpage-plugins are different.

Thus, it can achieve the effect of display at different kind of data rate.

B. The FLASH player can be used without compulsive demand for downloading any plugins or

software.

C. Flexible backstage P2P accelerator. You can choose to close or open the P2P function.

D. It is convenient for those website which have used FLASH player before to transform into P2P

mode.

[client software for watching]

—— It requires users to download and install the watching software. This software will become

independent playing one after starting. Also, it allows installing such module like standard P2P plugins

player and accelerator at one time.


A. It occupies the desktop of watchers that can increase access to operators.

B. Offering diversified client function.

C. One time is enough for finishing installation of the download tools and plugins which are needed

under other modes.
