What else is worthy of our in-depth understanding of videoconferencing?
As more and more enterprises and institutions begin to adopt video conferencing and experience the advantages it brings, video conferencing systems are rapidly gaining popularity at an unprecedented rate. Coupled with technological advances, integration of voice, video, and data, and the development of network infrastructure, video conferencing is becoming a key tool for companies, educational institutions, and medical service providers. What is the direction of future video conferences? We can simply understand them first.
One topic that is currently very popular in the videoconferencing industry is 4K video conferencing. The advantages of 4K are numerous, but its system requirements for the entire project are also quite high, because the current H.265 encoding is not very mature, so the mainstream coding technology still exists. For H.264, this kind of coding technology, the demand for storage in 4K will increase exponentially with respect to 1080P, and in many current monitoring projects, the expenditure occupied by storage has reached more than 50%. This cost is Increasing the weight that will bring unbearable costs to users, how to solve this problem is worth pondering.
Low-light video conference camera is also an inevitable development trend in the future. The biggest difference between low-light camera and ordinary camera is the imaging effect of the camera in a low-light environment. Without the need of additional lighting equipment, the effective illumination value is 0.001Lux and below. , often referred to as a star-class camera, this is the best type of low-light camera, Danone has also launched the latest star-class camera, the effect is obvious to all.
The mainstream of the future is the application of high frame rate technology. Before the popularity of H.265, 1080P@50fps requires a bit rate of about 8Mbps to achieve good results, which means that the storage space and bandwidth increase users. The cost. Whether it is the front-end camera or back-end storage, the increase in the frame rate will inevitably increase the amount of data. For 50fps, the data volume is twice that of 25fps. Faced with double the storage, double the storage time, idle hardware and software, system performance in this, the processing screen has doubled, making the data management and processing workload also increase. In addition to this camera's sensor, bus design, video processing chip, encoding compression algorithm and body heat issues, it also means that the cost has been increased to some extent.
