The need to acquire a clear image on your video recordings is obvious, but the team of the potential safety benefits can provide the image recorded is less clear. For network security applications, video bit rate - the rate by which the recorded data is transmitted - is critical to the efficiency of any system and its successful implementation. Reducing the bit rate required to maintain excellent video quality leads to a more efficient product. Ateme H.264 encoder has been optimized and enhanced to provide high video quality at exceptionally low bitrates. It is totally normal according to the guidelines governing the H.264 standard. The company uses an open standards approach, which means that the computer can be used with many other products on the market and therefore customers will not be forced to stay with the property of the assembly, giving a total cost of the property. Even compared to MPEG-4 encoding technology, the previous generation, customers can expect to benefit from a 30% reduction in bit rate of the same quality video. This results in reduced network costs, reduces storage requirements due to smaller file sizes and most importantly, reducing costs for end users. In some cases the results obtained in the video quality may even be greater as MPFG-4 H.264 can not compete in quality with low bitrates. The company has defined its H.264 encoding technology for many years and in that time has implemented solutions to improve their customer sites worldwide. Of course, these are not just at airports, this team can be found overlooking many other facilities such as roads, railway stations and toll booths. This latest version of the compression standard - H.264 MPEG4 Part 10 or AVC (1) (Advanced Video Coding) The video compression techniques used in the H.264 standard, jointly developed by ISO and ITU -T. See H.264. (2) (Audio Visual C (Advanced Video Coding H.264 Advanced Video Coding See H.264 -.) CODEC - replaces the previously successful MPEG-4 (MPEG-4 Part 2) video coding is the last cutting-edge video compression standard available in the market today. The reason that unlike other encryption technologies (MPEG-2, MPEG-4) is due to its many sophisticated techniques that allow video to be compresses much more efficiently, making it more flexible and suitable for any type of network constraints that may exist. Details of a similar technology to other encryption technologies Ateme create profiles to be used to group together certain sets of features that target specific types of applications. There are four main profiles that exist in the H. 264 The first is your basic profile, which provides low latency applications such as videoconferencing and mobile applications This is complemented by an extensive mobile applications streaming, .. in your main profile, for interlaced video and media systems and. high-profile, high-definition of requirements, such as television screens the H.264 's improvement was achieved mainly through Using techniques such as motion estimation, which minimizes temporal redundancies (similar blocks at different locations in two video frames) Intra estimate that minimizes spatial redundancies (duplication of the elements within a portion of a frame) , reduction of compression artifacts,. entropy coding, which assigns fewer bits to frequent symbols and more bits to symbols frequently found two versions of entropy coding used in the member ATEMF ATEMF of the Association for Tertiary Education Management products include CABAC CABAC binary arithmetic context Adaptive Coding (video encoding algorithm) (context adaptive binary arithmetic coding context-adaptive binary arithmetic coding (CABAC) is a form of entropy coding used in H.264/MPEG-4 AVC video encoding. As such it is a lossless compression technique inherent.) Adaptive Coding and CAVLC context of variable length (video encoding algorithm) CAVLC coding based Adaptive Variable Length Coding (video encoding algorithm) (adaptation to the context of variable length coding Context-adaptive variable length coding (CAVLC) is a form of entropy coding used in H.264 / MPEG-4 AVC video encoding. It is used to encode residual, zig-zag for 4x4 (and 2x2) blocks of transform coefficients. ..... Click the link for more information.). The data are compressed more efficiently with CABAC to CAVLC, CABAC coding but requires much more processing power to drive it. Although CAVLC is less complex than CABAC, it is still much more efficient than other techniques used in coding coefficient, as used in MPEG-4. New advances in video quality and the prediction of performance is achieved through the use of a deblocking filter, which eliminates block artifacts (common to other coding techniques). This is possible to soften the edges between the blocks within a frame. This filter also greatly improves the visual quality of a frame in comparison with similar bit rates of MPEG-4. Ateme has introduced a revolutionary feature that allows two H.264 video streams to be encoded from the same source and live different frame rates in a single digital signal processor digital signal processor (DSP) is a specialized microprocessor designed specifically for digital signal processing, usually in real-time computing. Typical features of digital signal processors designed for * real time * processing (DSP (1) (Digital Signal Processor) A special-purpose CPU for applications in digital signal processing (see definition # 2). It offers ultra -fast instruction sequences, such as change and add and multiply and add, which are commonly used in math-intensive), which is a version of an alternative technology CPU CPU in full component main central processing unit a digital computer, comprising a control unit, a unit of instruction, decoding, and arithmetic-logic unit. But is essentially the ability of the processing equipment / power. This is especially due to the limited processing power available in the DSP and can only be achieved due to the aerodynamic evolution Ateme encoding engine. This is important for situations where the video is being monitored on a full frame rate, but recorded in a lower bit rate. Variable frame rate (. VFR VFR abbr visual flight rules) is a feature that reduces and increases the frame rate depending on the movement in a given area, ie no activity in the frame, the images may not are necessary and can therefore be discarded. This, together with the bit rate and low, further reduces the amount of disk space required to store a video file. The latest version of the H.264 can automatically adjust the bit rate depending on the actual activity of the image. It is perhaps the most important technology incorporated in H.264 encoders in recent months. This gives you the ability to consistently produce sharp images with variable bit rates. The need for this limitation came from a constant bit rate (CBR (1) (Computer-Based Reference) Reference materials accessible by computer in order to help people do their jobs faster. For example, this base data on the disc! (2) (Constant Bit Rate) A uniform transmission rate.) encoding mode. By implementing this process, the bit rate reductions of 60% can be achieved compared with bit rates of video-like quality MPEG-4 "The company's engineers found that the CBR mode encoding produced great image quality in low activity was -. But when there was a lot more activity and movement, image quality can be degraded. With this technique, the probability of dropped frames are degraded or removed, as it is much more flexible than the CBR and also allows the image to remain sharp and clear while still providing the control on the maximum bandwidth used. Another advantage that the manufacturer claims that H.264 has been compared to CBR equipment is its high efficiency. With the new product, the bitrate is consumed only when needed, resulting in network traffic, even less, and reducing storage needs. the user of open technology standards Ateme H.264 coding of 's is 100% compatible with the guidelines for the rules, and is believed to be an important consideration for potential customers, saying other teams, may lack what he calls open standards, will result in fewer options for those who require such a system. that meets the flow also means that H.264 's video can be decoded with the standard software such as VLC Media Player VLC VLC VideoLAN Client VLC variable length coding at very low cost Logic Controller Visual VLC VLC Valencia, Spain - Valencia (code airport) Virtual Collaborative Learning VLC VLC codeword of variable length Settlement VLC player or QuickTime[R] low, which can be an important consideration in the management of licensing video over a network this -. As mentioned earlier in this article - you can lock customers into proprietary systems, which means that buying compatible with standard technology gives users greater flexibility and avoids the need to gain complete (and potentially more expensive) H.264 solutions is designed so that its customers have the extension. option to combine the security components of the system without worrying about integration or data formatting problems. If the buyer has the following options, more competition exists, which should mean that the client benefits from commodity prices lower. Today and tomorrow Ateme current product range is based on H.264 technology to significantly reduce the costs of upgrading the security systems can be integrated directly with the user's existing infrastructure. It is possible to retain existing analog cameras, while the simple installation of H.264 encoder, which will become standard analog CCTV CCTV abbr. CCTV closed circuit television closed circuit television solutions up to a state of the art IP network video solution providing the highest quality video at lower bitrate. To completely new video security installations, customers are opting for the use of analog cameras with the Ateme encoder for video quality resulting from mixing with the analog camera is far superior to that obtained video from IP cameras. This, he argues, is due to the fact that the IP camera technology is still in a stage of evolution and is limited by the hardware and price limitations, although the company believes that this trend will change in the next five years. The prototype of the latest version of the H.264 encoder made its public debut at the recent exhibition from Munich airport in Europe. It is expected to be commercially later this year If you want to download VLC Media Player visit:. vlc media player
