"Speed ​​and Passion" dual-stream playback technology under high-definition surveillance
Today's security industry has entered the era of so-called big Internet. Many companies, especially financial institutions, have established multi-level video surveillance networking platforms. Using a network throughout the country, the headquarters of a financial institution can call the surveillance video of each branch at any time. However, in real-world applications, due to bandwidth limitations, many enterprises cannot meet the remote call requirements at low network speeds under high-definition surveillance. “Speed ​​and Passion†seems to be unable to balance the security industry in China. In view of this situation, Blue Star has pioneered the “Double Stream Playback Technology†in China, which can export both high and low resolution videos in real time. It can meet the remote call requirements at low network speeds and ensure the storage of high-definition video. This undoubtedly provides a new solution for HD applications and remote management in the domestic security industry.

Cost and management requirements spawn double stream playback
Today, using the network to watch HD video remotely has become a normal state. Especially for financial institutions such as banks, this demand is even stronger. Some senior practitioners of the bank said: "In the past, we only occasionally watched the live broadcast. But now, the security monitoring system has taken on more and more management functions. We must not only respond to the remote call video of the public security department. Demand. Now the daily meeting video of each branch, the management of the operation of the mortgage car, etc., the headquarters needs to be able to call real-time video data in time."
However, perfect HD video surveillance and remote calls are not an easy task. "Now, the lengthening of video data storage time and the continuous expansion of monitoring scope have caused tremendous cost pressure on us. The hardware has to be upgraded and the software has to be upgraded. Sometimes it is really powerless." Bank IT managers This complaint is often issued.
In fact, the above complaints are not groundless. At home, bandwidth is still one of the main factors limiting Internet HD applications. At the just-concluded "2013 Asia-Pacific Big Video CDn Development Summit", experts in the industry have suggested that foreign countries not only have broadband speeds far higher than domestic ones, but because of the particularity of the Chinese market, the cost of domestic bandwidth is about four times higher than that of foreign countries. 5 times. In this case, Chinese security users want to guarantee high-definition storage and remote real-time calls, which undoubtedly cost a lot of money. It is also unrealistic to solve the problem of high-definition storage and transmission by greatly increasing the bandwidth. It is based on this situation that dual-stream playback technology came into being.
Large network HD monitoring drives future application trends
The biggest advantage of the new dual stream playback technology is that it can provide low bit rate substreams to meet the needs of remote network transmission without any additional hard disk resources, ensuring consistent playback of the picture, even in low bandwidth situations. You can also view smooth video recordings. In essence, dual-stream playback technology takes into account image quality and transmission quality in the absence of existing network bandwidth. Allows users to flexibly select the stream format based on network bandwidth to achieve local HD storage and back-end low-stream network transmission.
Dual stream playback technology is a speed increase for network video surveillance. Especially in the financial institutions with increasing network points and limited network resources, but the video surveillance system is constantly generating massive video, audio, storage, alarm and management data, it can ensure the stable operation of the transmission system.
For dual stream playback technology, the prospect of dual stream playback technology is very promising. On the one hand, network transmission of large networks has become a trend, which is the best monitoring transmission method to solve the long distance between the metropolitan areas and the extremely scattered points. As long as there is an internet network, it can be monitored by installing remote monitoring software. And control. In this case, dual stream playback technology will inevitably be recognized by more and more customers. On the other hand, HD has also become a trend, and our dual stream playback technology is moving in the direction of high-definition dual stream playback. HD real-time dual stream playback allows customers to achieve high-definition pictures when storing and outputting video. Quality, even the 1080p resolution format is 25fps full frame rate real-time browsing, users can not only see continuous images, but also miss or miss any key event.
The era of big Internet has broken the phenomenon of “information island†of security monitoring, and the dual stream playback technology has made the connection between different “information islands†closer. Today, with limited bandwidth and increasingly stringent cost control, Blue Star's dual stream playback technology allows customers to achieve higher roi (return on investment), and the "speed and passion" of HD video surveillance storage and transmission. It will inevitably become a new trend leading the development trend of the industry!
