THE BASIC CLASSIFICATION OF THE DVR
DVR due hundred schools of thought contend in the early stages of development, a wide range of stakeholders for the industry rather "confusing" feeling, after a period of time after the changes, the classification of various types, about the forming. According to the Taiwan Industrial Technology Research Institute Photoelectric Industrial Research Institute "Optoelectronic Industry Analysis" report, the DVR broadly divided into all three categories:
1. Type Digital STB
STB refer to the Set-top Box (generally translated into: digital satellite receiver, set-top boxes, Internet-TV, video-on-demand box, and so on, because translation differences, and therefore collectively referred to in this to the STB). Digital STB types of DVR functions in the nature of the signal reception integrated platform to provide digital video function and receive digital broadcasting and interactive applications based signals, the option to receive digital wireless terrestrial transmission (Digital Terrestrial), digital cable television distribution (Digital Cable), digital satellite transmission (Digital Satellite), and other different types of communication signals.
2. PC-based types
PC-based DVR types of its application platform for the general PC, portable computers, and so on. The installation of a PC video capture card or film, using software image compression and image editing function implementation, the system more unstable.
3. Single (Standalone) type
The DVR is a single-CPU and RAM to use to develop the design, using proprietary software program, research and development costs are relatively high. Using hardware compression, quality and stability, there will be no freeze up problems, and the images are stored in speed, resolution and image quality, both larger improvements. This type of products provide only purely functional digital video recorders, such as other broadcasting without additional signal reception, on the Internet, and other functions. As used in the field of security surveillance products are mostly above Category 2 and 3 category, this article will only do these two types of. PC-based and stand-alone type of system types merits of the dispute, so far still unable to draw a conclusion. Although the current PC-based DVR accounted for the majority of the market, but it has been observed, the two types of products will have a market segmentation each. 1995 is the development of the area into DVR Japan Ikegami company and its overseas manager Yasuhiko Saito pointed out: "DVR market will be two different directions towards development, on the one hand, as RTOS (Real time Operation System, real-time operating system) in the reliability of the operation is expected to be greatly the development; but on the other hand, stressed that the DVR could networking products, the Windows operating system because it is simple and will become a mainstream. "
DVR technology is still in development, one of which is the key technology operating system and imaging compression technology.
1. Operating system
1. Windows interface for operation
With regard to the PC as the main structure of the DVR, the use of the Windows platform with its simple, universal application of the characteristics of various operating systems and ranked list of the top. South Korea 3 R Group CEO Chang Sung - Ik said: "At present the majority of DVR and related products manufacturers use Windows-based operating system; Especially in the United States such a big market, users in order to facilitate future maintenance, and more inclined to use Windows-based DVR products. " Korea Digital Logic overseas marketing manager Jonathan Kim also said: "We believe that the Windows operating system is the most suitable for DVR family of products. Because Windows is a generic operating system, therefore a higher support, regardless of any local support can be most Windows-related products. "
In addition, Windows software upgrades, also stronger than other operating systems. In recent years, the IT industry is closely related with the Security Industry, when digital technology in the IT industry into the 10,000 kilometers At the same time, related technology development which is bound to affect the security industry. The reason why Windows will be loved by many vendors, is because it has a great scalability. Manufacturers that since DVR systems can not stay long-term at fixed levels, the upgrade of systems development is bound to become a key point. If cost considerations and eliminating the old, once users have a system for both higher requirements or legacy systems exposed some flaws, most of the customers less likely to buy a new system to replace, so that products on the escalation of a prime solution.
Although vendors, system stability depends on the user's actual operation, however, the Windows operating system itself is unstable, so that users still considerable doubt. Some manufacturers have said that if the use of only simple monitoring system, Windows 98 system fairly stable; But if the Windows platform running other procedures, system instability, or even crashed on the inevitable.
2. Linux interface for operation
IT industry in Windows and the Linux operating platform also spread to the fierce competition Security industries. Linux can be used for the operating environment will allow many users at the same time within the mainframe computer at the same time the use of the resources. Linux provides a complete people (Multiuser), multi-tasking (Multitasking) and multi-trip (Multiprocessing) environment, can be downloaded on the network to use. Because of its original code (Source Code) is open to the public, it can be developed, modified, so Linux users need not have to trouble the lack of applications, and has accelerated the pace of research and development, and the system itself and most of the application is free, allows developers to save large sums of R & D expenditures. In addition, lower demand for Linux hardware, users can save hardware costs more input, then reduce overall product cost. With the prevalence of Internet, the global use of the Linux people more and more, and attract numerous inputs improved core developers, the application software and hardware peripheral driver ranks so that the function and integrity of Linux growing to become parties to focus attention.
In addition, Linux is based on the network environment the operating system with a comprehensive network function, users can even Linux on the Internet singly, may also set up local area network (LAN); Linux can also set up various Server to provide Internet and Intranet in the mail, FTP, Web ... services. In such a trend, Linux DVR manufacturers eager to become the operating system. Some vendors even indicated that Linux more suitable than Windows applications on the DVR. South Korea Eastern Info-Com companies overseas markets that the Ministry of Associate Hyoksang Kwon, said: "As more Windows unstable, and the high prices, in contrast, Linux seems to be the most development potential of the mainstream operating system."
In fact, now under "Linux as a DVR will be superior to the Windows operating system" still too early to draw such a conclusion. According to other manufacturers respond in Linux compatibility there are still some problems, such as printer support, such as Internet connectivity, such as Windows do not. In addition, already accustomed to using Windows applications users, will be the beginning of the operations are not suited Linux; While Linux can read Windows files, but Linux still unable to read files on Windows systems shortcomings, coupled with the subsequent rise of the Linux operating system, so in the current peacekeeping staff is not very adequate for the circumstances, the use of many manufacturers choose to use Linux systems will also have some psychological barriers.
3. The operation interface to RTOS
For single - or PC-based DVR is, RTOS (Real Time Operation System) is the best operating system, currently available in the market this type of supplier mainly to South Korea and Japan. Many South Korean manufacturers such as 3 R, Korea Computer Technologies, Kodicom, Artinix feel that single-DVR with high economic efficiency, high stability and Security Controller and the existing high compatibility, and other features, it rolled out the first time, have a single type of DVR. For Japanese manufacturers, will be committed to the development of single-DVR is mainly based on considerations of image clarity, the majority of PC-based DVR image quality are not as single-DVR.
However, the current single-DVR is the greatest challenge facing the networking functions. All in networking today, a growing number of Internet users, Korea Digital Logic's Jonathan Kim that said: "When we talk about single-DVR, the networks often omitted swap part of the remote control. But DVR systems and network convergence if not, to be honest, it not a DVR system. " Most western manufacturers also have the same viewpoints, such as the United States, Germany, Britain and other Nordic countries, has been the network will function as digital CCTV products is the key. British Dedicated Micros chief executive Mike Fawcett illustrate: "Britain's chemical industry, manufacturers have adopted the function of the network DVR equipment, in addition to substantial savings in manpower costs, but also can be anywhere monitored the staff and production line status, thus saving many costs." Can networking features allow users through LAN / WAN, Internet and other network remotely monitor. This characteristic has been forecast to become the mainstream of the future CCTV market. To enable products with networking capabilities, single-DVR manufacturers into "price vs. Functional "dilemma. Korea Korea Computer Technology Corporation general manager Y. H. Min pointed out: "To allow DVR with networking capabilities, we must add standalone DVR certain type chip. Therefore, we must increase the amount of investment and cost, price competition in the increasingly severe circumstances, the cost increase to our considerable disadvantage. "
2. Compression Technology
At this stage DVR used by the compression technology to JPEG, MPEG1, MPEG2 - based. Strictly speaking, these compression technologies may not be able to fully meet the demand for a long time video.
1. JPEG
JPEG compression multiples of 20 to 80 times, for the static picture compression, resolution no choice. Previous JPEG compression technology is directly deal with the entire picture, so we have to wait until the completion of the entire compressed file transfers only started to extract video sources and picture, and the means to cause such a high resolution picture transmission to be time-consuming tens or even for a few minutes. The new generation of JPEG is gradually taken-layer technology, the first transmission Document Analysis low, and then supplemented send details of the information so that the picture quality improvement. The time required for this method although the same manner as with the original, but because it can first see the screen, so users will feel better this way.
2. MPEG1 and MPEG2
While MPEG1, MPEG2 in mobile imaging under the circumstances of having little compressed multiples approximately 100 times (General VCD, DVD about 35 times), from VCD, DVD specifications, MPEG1 the resolution of 320 x 240 (or less), MPEG2 is usually 720 x 480. MPEG1, MPEG2 is a transmission-in action partial picture.
3. MPEG4
As for the compressed multiples of 450 times (static images up to 800 times), the resolution can be imported from 320 x 240 to 1280 x 1024 MPEG4, it is designed for mobile communications equipment (such as mobile phones) in the Internet real-time transmission of audio / video signals and the latest development of MPEG standards. MPEG4 and MPEG compared to the previous version, the biggest difference is MPEG4 use of "layers" (layer), the images can be intelligent choices differ, the individual editors in the compressed images to map documents capacity substantially reduced, and speed up the audio / video transmission. Some people think that MPEG4 the emergence of the DVR manufacturers, is undoubtedly a blessing, but also some manufacturers that MPEG4 specifications Although set, but the actual application of the DVR technology has not yet matured, at this stage, both in software and hardware have to be to achieve a breakthrough (details of the "technical articles - MPEG4 pressure DVR technology in the reduction of the article ").
For what compression DVR products more applicable to the views of the views of manufacturers were very different. South Korea 3 R's IK Chang Sung-specific: "Generally speaking, compression technology uses two methods, one is intraframe, the other is Interframe. Interframe imaging can distinguish between each piece of the difference, and only transmit images of different parts of H.263 and MPEG is the representative of this format . The animation Intraframe way put a decomposed into a number of fixed images of a piece of a transmission to this end Wavelet and Motion JPEG mode representatives. from the transmission efficiency considerations, Interframe in performance is far superior to Intraframe; but, Interframe technical changes in the smaller screen circumstances, can not provide much wrong definition. " However, the security products must take into account the user image-quality problems, and in this connection MPEG and JPEG to Wavelet more favorably. Digital Logic's Jonathan Kim, said: "We recognize the MPEG4 video compression comparison outstanding, but there are MPEG series of images of interference and distortion of the picture distortion. If users want to buy a large amount of storage DVR, he can consider MPEG compression format; But if users want to have good quality, it should consider other means of compression; As for the good in one way, depending on customer needs. " Eastern Info-com companies Hyoksang: "image clarity, and image compression rate of the CPU and other related hardware is inversely proportional to the load, as MPEG4 with high compression ratio, the resulting image is not clear, the Security Industry to achieve the standards required for the image, a lot of room for improvement. " DM company's executive president Mike Fawcett further pointed out: "For static images, whether using JPEG or MPEG compression mode compression mode, the transmission speed is the same. However, if the object is the state of sports show, MPEG format will not immediately react transmission, it is because MPEG the slower speed transmission format, or in monitoring the scene prone to interference. " In his view, both in JPEG image compression technology in the quality or speed, is more suitable for Security industries. He said: "I think the quality JPEG better, more competitive, but also more secure." Along with the constant development of DVR technology, the storage capacity is expanding, and the quality requirements of users will inevitably rise higher and higher. British Visionfactory chairman David Beanland said: "Although the JPEG image format and Wavelet uses larger storage space, but this kind of compression technology in the DVR industry is still mainstream. Undoubtedly, the DVR storage capacity will be gradually expanded storage capacity of 200 GB above DVR will be the slowest in 2 three years later appeared in the market. Once the capacity problem is solved, users will be to focus on image quality, and MPEG compression technology approach will be eliminated. " Beanland also questioned MPEG compression technology can record images as reliable evidence in court, the current market in Europe and the United States also is open to question. Philips is working in the company, with 14 experienced Alan Everid think that the DVR products, Wavelet compression is the best way. Wavelet remove the main reason lies in the high-frequency components of the image (high frequency components), retaining only single-frame image signal. This feature is particularly applicable to the frequent changes in the screen occasions, such as time-of-use multi-screen display. However, although the Security Industry Wavelet Image request, but in consideration of whether interconnection factors, readers should pay attention to the Wavelet existing IT networks is not generally supported by the format, so the use of the network will be limited.
