Analysis of HD video conferencing system

Video Conferencing has been developing for many years. So far, the quality of images that video communication can transmit is still limited. When the resolution is low, the participants seem to be fuzzy. However, enterprises still want to maximize the video quality.

With the continuous improvement of processing technology and the emergence of new standard display technology, the resolution of video images that enterprises can obtain in their existing video conferencing systems has increased by 10 times. A new system that provides HD resolution video quality can bring users an immersive experience, greatly improving the Conference efficiency and quality. In addition, the plug-and-play functions and simple control features of the new system are equally important to video conferencing users.

The requirement of the video communication system is that the following 10 questions have an important impact on the user's correct decision.

1) Why are you planning to purchase a video conferencing system?

Global Business is going global and people need to meet and communicate with each other frequently. Although the expenditure such as cost difference does not account for a large proportion of the enterprise's income, other invisible factors often have a very important impact on the development of the enterprise, video Communication systems can help enterprises improve production efficiency, grasp market trends in real time, and improve the efficiency of team collaboration. These factors are usually very important for enterprises.

For enterprises, the use of video conferencing systems can grasp the market in real time and win a competitive advantage. Educational institutions can connect students and teachers in different regions to share classroom content and learn from each other. Public authorities can provide immediate information, increase security factors, and provide critical communication tools for emergencies.

2) Why is HD resolution important in audio/video communication?

The benefits of video communication systems can only be seen and heard by people in different regions, and people feel like they are in a room. However, due to processing capacity, bandwidth, and other factors, the quality of video conferencing systems is also limited. In many cases, the "real experience" promised by the vendor cannot be fully achieved.

Compared with traditional video conferencing systems, the new HD video system solution provides 10 times higher resolution than the system 10-15 years ago. The resolution currently used by the system is FCIF (352x288 pixels), while that of the HD system is 1280x720 pixels. In the real sense, this is the difference between seeing each other and clearly feeling each other's expressions.

For example, in order to make timely decisions as soon as possible, a textile factory that purchases fabrics needs to communicate with buyers of the other side of the globe. In this process, clear textile details and quality can have an important impact on decision making.

High-Definition and high-fidelity audio communication is also an important factor to ensure production efficiency. The natural and full-duplex audio quality covers the entire conference room, making it very important for all attendees to hear the Meeting clearly. Video Effects without high-definition audio quality cannot meet the expectations of end users.

3) is the HD video conferencing system compatible with my existing installed video conferencing system? How should I protect my investment?

First, make sure that the system you are currently using uses general standards (such as H.264) rather than some proprietary protocols. All users want their systems to maximize interconnection and connect more colleagues, suppliers, customers, and other enterprises. One of the issues to be considered is resolution conversion, which ensures optimal quality of each system in each call.

4) Will HD systems be more expensive?

Compared with the existing video conferencing system, the cost-effectiveness of the HD conferencing system is extremely competitive, and the resolution of the new system is 10 times higher than that of the existing system, the price is similar to that of a general conference system. In addition, the price of HD display is also falling rapidly, and the bandwidth demand for conference calls is also decreasing.

5) How much bandwidth is required?

This problem mainly depends on the system you plan to use. For HD video communication, you need to prepare a bandwidth of 1 Mbit/s. The previous system bandwidth is 384 Kbit/s or 512 Kbit/s. In addition, some enterprises are using up to 25 Mbit/s (bidirectional) or 2-5 Gbit/s to obtain high-definition video quality. In the past five years, with the popularization of bandwidth, the quality of high-quality HD videos will be more accessible.

In addition, both 384 Kbit/s and 768 Kbit/s can provide better video image quality at any bandwidth, because the processing and encoding capabilities of the new system have been greatly improved.

6) Can I run HD video communication on the display screen of a standard definition TV device?

In fact, the user can run the HD system on the standard definition TV display, but it cannot reach the Full HD standard of 1280 × 720.

7) Can I share multimedia and PC presentations?

In many applications, the ability to share multimedia content and perform PC demonstrations is an important factor. Users should consider these issues when measuring the system. These functions allow you to connect a PC to the system, plug-and-play, and obtain a high-definition resolution in the 16-9 format without losing any resolution. At the same time, it is extremely important to ensure that multimedia shared content is compatible with other standards. In addition, you should also consider whether you need to add another camera in the application to display other locations in the room or other participants.

8) Can the ease of use of the system be improved?

The simplicity and ease of use of the system is usually very important for users and can greatly improve work efficiency. Interestingly, compared with the standard definition in the 4-3 format, the high definition in the 16-9 format may need to constantly move the camera to see all attendees. Therefore, the transparency of technology is for users, it will be very important.

It is vital to make the system easy to use when initiating a call, multiple calls, running a camera, and sharing multimedia content.

Of course, it is equally important for the system to have video management software. This will help users to book, monitor, solve problems in real time, and report to systems of multiple vendors for intercommunication ). With video management software, the IT department can provide end users with the best user experience and meet service level requirements.

9) Can I hold multi-point HD meetings?

Before purchasing a system, confirm with the manufacturer whether the system they provide has a multi-point control unit or an external multi-point control unit that supports HD video communication. Many meetings are not limited to end-to-end calls between two points.

10) Many vendors say they have high-definition conferencing systems. What should I do?

When selecting a high-definition conferencing system, consider the following factors:

Fully demonstrate system functions;

Cost effectiveness;

Real HD quality vsFCIF, 2CIF, 4CIF;

Market development and product development direction;

The product adopts standards and interconnection support;

Comprehensive and comprehensive product lines, including video systems, multi-point control units, management software and gateways;

High-Definition and broadband audio quality;

Stability of enterprise partners and enterprises.
