At present in the market the popular video frequency conference approximately divides into two kinds: Hardware video frequency conference system and software video frequency conference.
these two kind of between comparison:
sound video frequency quality
- hardware product: The audio frequency code uses International Telecommunication Union ITU organization H.320 standard G.7xx the audio frequency code standard.The sound is the process damage compression.
- software product: The traditional software solution gives people's impression is the sound video frequency quality relative bad.But fast strengthens unceasingly along with the PC CPU handling ability, so long as the user has certain band width, the audio frequency code might use the code besides International Telecommunication Union ITU organization's H.320 standard G.7xx, but also might use other third party audio frequency to code the standard (for instance GIPS pronunciation standard.May realize compared to the hardware video frequency conference system clearer sound effect.
easy to use
the hardware product: This is the hardware solution traditional superiority, the easy to operate, conforms to the user tradition use custom.
software product: On the one hand along with computer and Internet application popularization, the people are more and more familiar to the computer application and the custom; On the other hand, software product in technical design and function realization full consideration product use conveniences and friendliness, causes mostly the user not to need special training then immediately to use
price
the - hardware product: The disposable purchase price is expensive.Moreover because needs certain band width, user long-term payment band width turning on expense.
- software product: The product price only is the hardware product several 1, even lower.May use the existing network condition completely.
the technology renews
the - hardware product: The hardware product life cycle is approximately 3 years, but the technology is renewing every day, the special-purpose hardware equipment is unable to catch up with the hardware technological development the step.The hardware will renew or replaces the new promotion module extremely to be expensive, moreover will implement is not convenient.
- software product: Any new technical application and the function strengthen all may renew promptly for the user, anytime and anywhere, extremely convenient.The product promotion price compares the hardware product to have to lower a lot.
network band width compatible
- hardware product: Is high to the band width request, needs above 384kb generally the independent line or the special net.The solution firewall question too is complex.
- software product: May use the user existing network environment.Suits in from the 56kb digit dialing, xDSL, the special line, or other way turning on network environment, adapts each kind of proxy server and the firewall.May meet the different network environment need.
the data cooperates
the - hardware product: The early hardware product does not provide the data cooperation function; At present some high end hardware manufacturer needs to increase the special module in its system, needs extra PC to support this function, the system connection is complex.
- software product: Has a body data cooperation function, may provide documents sharing, the electronic tabula rasa, the coordination browsing, the writing exchange and so on each kind of function.
system deployment and dilatancy
- hardware product: The hardware product acts according to MCU the request, the deployment points limit quite is big.
- software product: According to the server and the band width demand, the volume of users may achieve hundred and thousand of user quantities.
the firewall supports
the - hardware product: Is extremely weak to the firewall support ability, requests each terminal all to have strictly to have exterior IP, but and may visit the Internet not to be able directly to pass through the firewall.
- software product: To the NAT firewall, the agent server as well as the package of filtration firewall all have the corresponding solution, under the majority user environment, the user does not need to make any disposition then to use.
portable
- hardware product: The majority hardware product is applies in the fixed conference room.At present in the market some video frequency conference supports the tabletop terminal, but these in the use, the function, the efficiency all receive the very big limitation.
- software product: May use own notebook computer, anytime and anywhere (or the IP network holds the video frequency conference through the Internet.
the conference manages
the - hardware product: The conference manages the function to be simple.
- software product: May provide the rich conference management and the control function, like the user data bank administration, the conference appointment, the conference inform, the conference counts, summit agenda, voting and so on; Provides the different conference type and the conference according to each kind of conference demand controls the pattern and so on.
customization
- hardware product: Cannot satisfy any user personalization nearly the demand.
- software product: May act according to the user the demand, provides the customization the contact surface, the function, as well as customer brand.
