【 Weak current College 】 hardware video meeting system and software comparison-video conference--Power By 【 China power house network 】

Current market broad popular video conference is divided into two types: hardware video meeting system and software, video conferencing, this difference between the two species is mainly expressed in the following areas:

1. audio and video quality Hardware products: audio encoding uses the International Telecommunication Union ITU organized H.320 standard audio encoding specification G.7xx. The sound is a lossy compression.
2. software product: traditional software solutions to give people the impression that the audio and video quality is relatively poor. But with the PC's CPU power constantly fast enhancement, as long as the user has a certain bandwidth, audio encoding can encode in addition to the International Telecommunication Union ITU organized H.320 standard G.7xx, you can also use other third-party audio coding standards (such as GIPS voice standards). You can achieve better than hardware video conference system with clearer sound effects. Easy-to-use 1. Hardware products: this is the traditional advantages of hardware solutions, easy to use, consistent with the traditional use of the user.
2. software product: on the one hand with computer and Internet applications in General, people are becoming more and more familiar with computer application and habits; on the other hand, the software product in the technical design and implementation on the full account of products with ease and friendly, most users do not need special training to immediately use price 1. Hardware products: one-time purchase expensive. Moreover, because of the need for a certain bandwidth, the user will pay the cost of bandwidth access to long term.
2. software product: product price is only a fraction of the hardware product, or even lower. You can fully leverage existing network conditions. Technology Update 1. Hardware products: hardware product's life cycle is about 3 years and technology daily update, dedicated hardware device cannot catch up with the pace of development in hardware technology. Hardware update or replace the new upgrade modules are very expensive and not easy to implement.
2. software product: any new technical application and enhancements can be timely for the user to update, anytime, anywhere, very convenient. Product upgrade prices hardware products are much lower. Network bandwidth adaptation 1. Hardware products: the higher the bandwidth requirements, generally need more independent line 384kb or private network. Resolving firewall issues too complex.
2. software product: you can use the user's existing network environment. Suitable for dial-up from 56kb, xDSL, leased lines, or other means to access the network environment, adapt to all kinds of proxy servers and firewalls. You can meet the needs of different network environments. 1. the data collaboration Hardware products: early hardware product does not provide data collaboration features; some high-end hardware manufacturers need to increase in their systems, special modules require additional PC to support this feature, the system is complex.
2. software product: have one data collaboration features that can provide document sharing, whiteboard, collaborative browsing, text-chat and other features. System deployment and expand 1. Hardware products: hardware products according to the requirements of the MCU, deployment point limit is relatively large.
2. software product: according to the server and bandwidth requirements, user content can reach hundreds of thousands of users. Firewall support 1. Hardware products: firewall support very weak, strict demands on each terminal must have external IP, and direct access to the Internet rather than through a firewall.
2. software product: NAT firewalls, proxy servers, and packet-filtering firewall has appropriate solutions, in most user environment, users do not need to do any configuration to use. Portability 1. Hardware products: most of the hardware product is applied to a fixed conference room. Current market some video conferencing support desktop Terminal, but the use, functionality, efficiency will be greatly limited.
2. software product: you can use your own laptop computer, anytime, anywhere via the Internet (or IP networks) held a video conference. 1. the Conference Management Hardware products: session management functionality is simple.
2. software product: you can provide a wide range of Conference Management and control functions, such as the user database management, Conference booking, conference announcements, meetings, meeting agendas, voting, etc., according to a variety of meeting demand for different session types and control patterns. Customers of 1. Hardware products: almost can not meet the needs of any user-personalized.
2. software product: can according to user needs, providing customer-oriented interface, functionality, and customer brands.
