Regarding the definition of cloud splicing, there are different opinions. In different periods, the market has different needs for products, and the definition of cloud splicing is also different. At this stage, cloud splicing is to use the network (cloud). image, interface, audio, etc.) transmission, calculation, unified processing (processor), and then displayed through the display terminal.
The final characteristics of the product are determined by the needs of the market. On the premise that technology can be achieved, every enterprise hopes to make products with more complete functions, so as to widen the gap with competitors.
Market demand for cloud splicing
In the customer cases of STONBEL for many years, the size of the project is different, the demand for the product is also different, the engineering structure is basically the same, and the difference is mostly in the function.
The framework is mainly divided into: acquisition, transmission, processing, storage, display.
Acquisition: common such as camera, DV, computer signal, TV box signal, etc.
Transmission: direct connection, network/cloud;
Processing: video and audio codec, processing
Storage: Storage Services
Display: splicing screen
The above is the basic demand framework. In the customer contact of STONBEL over the years, our common customer needs can be divided into the following two categories:
Software: matrix switching of analog and digital video, video and audio codec, network real-time preview, optical fiber network cascading seamless interconnection, ring network support, H.264 video compression standard, composite video stream encoding, IPC, Encoding by NVR and other methods, decoding of private protocols of mainstream brand cameras, access and decoding of ONVIF, RTSP protocol devices, screen segmentation, splicing, overlay, windowing, roaming, screen capture, 4K display, scene preset, android, ios Mobile client, operation and maintenance management...;
Hardware: Modular (single maintenance does not affect the overall use), redundant power supply, redundant network port, intelligent fan, RS485 expansion port.
The current form of cloud stitching
Today, with the diversification of products and brands in the market, the products of cloud splicing processors are flourishing. In terms of the underlying kernel, some use the same Linux framework as STONBEL, and some use Windows, DSP, FPGA and other frameworks; in terms of splicing, it is divided into single-machine, dual-machine splicing, single-machine splicing and single-machine, cross-screen splicing; output image quality , divided into 1080P and 4K; in terms of functions, it mainly focuses on windowing, roaming, screen segmentation, echo, large screen recording and broadcasting, screen capture, scene planning, IPC signal storage, etc. The control methods are mainly divided into mobile terminal, PC terminal, chassis panel, etc.;
Pros and cons of current form
Advantages: The splicing requirements of security videos are the basic requirements of video processing. Most of the equipment in the entire industry tends to be stable. Whether it is in terms of transmission or processing, each manufacturer has its own fixed methods and solutions, and the network information is mature. Under the general environment, the function of the product itself has become the main area for the competition of various manufacturers;
Disadvantages: Due to the technical limitations of current intelligent processing, there is no deeper mining for data and signal processing, and truly intelligent computing and processing cannot be achieved.
Conclusion: On the premise of the stability of the product itself, the STONBEL cloud splicing processor has been striving to find a balance between security and demand to develop new functions of the product. The STONBEL cloud processor has achieved most of the functions in the market. At the same time, it has been committed to the research and development of products. STONBEL upcoming network cloud central control system combines the Internet of Things and smart homes to fully realize a set of centralized signal processing and control of Internet of Things devices.
