Advantages of hardware equipment: embedded operating system, anti-virus, high stability, and no virus data leakage caused by other software jamming, or downloading data or inserting USB flash drive. Professional equipment audio-visual effect is very good; In terms of appearance, the appearance of professional equipment is higher; You can use the LCD stand to integrate all the devices and wires on the stand for easy movement. As shown in the figure:
Suggestions on collocation method: software and hardware can be mixed: for example, if the number of people attending the meeting in the venue or sub-venue is less than 3, you can choose to bring your own computer+software and a small venue; If there are less than 10 people, you can choose desktop+professional external equipment; If there are more than 65,438+00 people attending the meeting place or branch, you can choose hardware equipment, personal office or business travelers, and you can choose laptop access (Note: when using laptop or mobile phone to attend the meeting, you must ensure the surrounding area.
Advantages of hardware devices:
Hardware video conference system mainly includes embedded MCU, conference room terminal and other equipment. Among them, MCU is deployed in the network center and is responsible for the processing and forwarding of code streams; The conference room terminal is deployed in the conference room, interconnected with cameras, microphones, televisions and other peripheral devices, and centrally processes data encoding and decoding.
1, highly integrated
Hardware video terminals can provide a variety of video and audio interfaces and network communication interfaces, and some of them also have built-in video matrix functions. When in use, you only need to connect peripheral video and audio input/output devices and access the network to use it. Hardware multipoint control unit (MCU) can integrate multi-screen segmentation, T. 120 data service, GK, digital mixing and other hardware modules. Its integration is much better than the way that multiple servers run together in a software system.
2. It has high security and stability.
The architecture has good anti-virus ability, and more than 99% viruses circulating on the network can't attack embedded systems. The design based on DSP processor makes the hardware video conference equipment have low power consumption and good stability. Some high-end hardware video conferencing equipment also has the functions of key processing unit backup, redundant heat dissipation, hardware AES encryption, firewall and so on, which further ensures the safety and reliability of the system and realizes the uninterrupted operation of the network for 7×24 hours.
3. Good audio and video effects
Due to the adoption of real-time operating system and efficient coding and decoding technology, the video quality of hardware video conferencing products is generally higher than that of software products, and the synchronization of video and audio is also easy to realize. Hardware video conferencing products can integrate video preprocessing, video optimization and audio optimization technologies to further improve the video and audio effects.
4. Flexible operation
Hardware video terminals generally integrate remote control function, and people who are not familiar with computers can set up and operate video conferences through remote control and OSD menu. Of course, the hardware video conference system can also be built and operated by PC, which is convenient for the control and management of large-scale conferences.
5. It has a good QoS guarantee mechanism.
Hardware video conferencing system can support RSVP, Diff Serv and other QoS technologies, through a variety of flying stars? Excellent low-level control and processing technology has been established for many years to ensure the good operation of video conferencing in an environment with poor network quality.
6, support a wide range of communication networks
The hardware video conference system can support system standards such as H.264, H.323 and SIP at the same time, and can adapt to various network transmission conditions of private lines or Ethernet.
Advantages and disadvantages of software
1. Advantages:
Software video is a video communication mode based on PC architecture, which mainly relies on CPU to encode and decode video and audio. Its biggest characteristics are low price, good openness and convenient software integration. However, the stability and reliability of software video need to be improved, and the video quality cannot surpass that of hardware video system. Its current market is mainly concentrated in individuals and enterprises.
Software video conference system is an important application of software video, which mainly adopts the structure of server +PC. Deploy MCU server, multi-screen processing server and streaming media server at the central point; Configure USB camera, earphone and conference terminal software on ordinary desktop PC; Configure high-performance PC, video capture card, conference camera and conference terminal software in the conference room. When holding a video conference, use a Windows-based user interface to set up and manage the conference.
1. Easy to deploy
2. Integrable data conference
3. Low cost
2. The weakness of the software video conference system:
Security and stability depend on computers.
Software video is based on Windows operating platform and PC architecture, vulnerable to viruses and hackers, and not suitable for long-term operation. Especially the conference room terminal based on software, which uses a large number of board cards and peripheral supporting equipment, has low integration, many fault points and is difficult to troubleshoot.
Video and audio effects are average.
The USB camera used in general desktop software terminals can only provide video quality lower than that of hardware 720P, with low frame rate and poor color reproduction. Although the conference room software terminal can be equipped with a dedicated conference camera, there is still a certain gap between video delay and quality hardware after video acquisition and software coding.
Advantages and disadvantages of Fishmeier in the industry
Advantages:
U 1, patented audio-video separation technology. In the case of poor network quality, automatically start audio priority, first of all to ensure that the conference sound is not stuck.
U 2, strong stability and safety. The server works stably for 7*24 hours, all audio and video data are encrypted with 256 bits, files are encrypted with MD5, and the server memory forwards them.
U 3, with a variety of software and hardware combination modes, multi-terminal mixed use, simple and fast conference use.
U 4。 With the exclusive patented HG264 video algorithm, the full HD effect of 1080P can be achieved in less than 1M bandwidth.
U 5, patented multi-screen * * * assistant, each participating client can push up to 8 PC desktops in the same LAN to enter the meeting.
U 6, Feishi Micron has as many as 9 patent certificates for video conferencing software, and each technology is one of the best in the industry with its own characteristics.
U 7, Fishmeier has service centers in more than 20 central cities across the country, which can provide our customers with faster and better technical after-sales support services.
U 8, Feiyuxing Company was established in 2002, focusing on providing network-related solutions. Feishimei brand relies on Feiyuxing's excellent network platform and has the underlying network technology that does not lose the first-line brands in the industry.
Disadvantages:
1, Fei Shimei software has been privatized based on international standard communication protocols, so Fei Shimei software is not compatible with international first-line brands (Huawei, Baolitong, Cisco), but the hardware is compatible;
2. In order to provide customers with a more stable and secure conference experience, Feishimei focuses on the C/S architecture (that is, the computer downloads the software client) and abandons the B/S architecture (that is, attending the conference through the webpage without downloading the client). B/S architecture is based on browser, which has the advantage of convenient participation, but it can't experience all the functions of video conference and make full use of computer configuration to provide better conference effect.
