Tektronix, the market leader in broadcast video testing, monitoring and analysis solutions, has announced that it has added many new features to its award-winning Sentry® digital content monitoring solution. The release of Sentry 5.0 enables Sentry to perform in-depth monitoring of video streams at full line rate (1 Gbps per unit). Other video monitoring solutions on the market cannot compare with Sentry in terms of speed and monitoring depth. This capability enables video service providers to monitor hundreds of video streams on a single machine, which can reduce the number of devices required to fully monitor a large number of multi-channel programs.
Sentry 5.0 introduces the concept of eMOS or Perceptual Video Quality, which can help service providers solve the problem of content that has good QoE scores but is distorted due to excessive compression-this is in sports-intensive sports Very common in the program. In addition, the new version also includes GOP length statistics, RTP support, and new reason codes to help service providers quickly understand the source of the problem.
"Cable operators and other video service providers continue to add new real-time and on-demand services, which increases the complexity of their networks, which in turn increases the possibility of video and audio errors," said Eric Conley, vice president of Tektronix video network monitoring , "We are committed to adding new features and functions to the industry-leading Sentry product line to enable our customers to stay one step ahead of the competition and enable them to rapidly expand their service scope while ensuring a high-quality viewing experience."
Full line speed monitoring complements Sentry's QoE scoring capabilities with new reason codes and its new mean opinion score (eMOS) scoring function, and the recently introduced advanced distortion detection function. These indicators can be used to compare and track the quality and performance of audio and video programs throughout the video network, thereby helping to analyze the root cause of quality degradation and automatically distinguish between the priority of problems based on user impact. For example, Sentry can generate a video quality score on incoming feeds at the head-end location before multiplexing the program, which can provide a baseline score for each program. After the program is multiplexed, another Sentry can generate single-ended MOS and QoE scores for related channel programs to determine whether the video or audio quality is affected. This scoring process can be performed at all recommended monitoring points in the network to provide an overview of the status of each program.
About Sentry monitoring solutions
Sentry is a comprehensive content monitoring solution for cable TV, communications, IPTV and other video service providers. Sentry supports early detection, diagnosis and repair of video and audio errors (ie picture freezing, macro-blocking, audio loss, etc.)-no matter when it occurs or where on the network, service providers Able to provide services with excellent quality to ensure that users get the best quality of experience (QoE). Sentry achieves this through its unprecedented network abnormal visibility at the IP and MPEG layers, the scalability of monitoring all programs in the network, and its unique combination of functions that run in real time and around the clock (24/7). Sentry's performance has been fully verified in the deployment of global service providers, including nine of the top ten cable operators in the United States.
TFT LCD screens are characterized by good development, high screen, strong sense of layering, and bright colors, but there are also relatively power consumption and low cost. TFT screen technology legendary the development of mobile phone color screens. Many of them support 65536 color displays, and even have 160,000 color displays. With a very high screen TFT, the visual advantage is important.
Technical characteristics
TFT technology was developed in the 1990s. It uses new materials and new processes for fine semiconductor all-electronic manufacturing technology. It is the basis of liquid crystal (LC), inorganic and organic thin-film electroluminescence (EL and OEL) flat panel displays. It is a variety of films made on non-single materials such as glass or plastic products (of course also on the surface) through methods and chemical reaction forming processes, and a large number of micro-integrated circuits (LSIC) are produced through the processing of the films. Non-single crystal crystals can achieve cost reduction, which is an extension of traditional small integration to large area, function, and direction. Manufacturing TFTs that control the switching performance of pixels (LC or OLED) on large glass or plastic products has a higher technical content than manufacturing complete ICs on silicon wafers. The required production equipment and production technology surpass the production of large-scale integration of semiconductors, which is the luster of modern technology. The main features are:
(1) Large area: The first generation of large-area glass products (300mm×400mm) TFT-LCD-production line was put into production at the beginning of the nineties, and the area of eye glass has been expanded to 60mm×80mm in 2000), as well as 950mm×1200mm glass The design will also run.
(2) High integration: The size of the 1.3-inch TFT chip used for the projection of liquid crystal is one million for GA. The resolution is SXGA (1280×100×1280×1000×1280×1000×1280×1000×16.1 inch TFT screen amorphous film) 50nm, and TAB ON GLASS and SYSTEM ON GLASS technology, its IC integration, The technical requirements for equipment and supplier technology are more difficult than traditional LSI.
(3) Powerful function: TFT as a matrix selection solution provides the light valve characteristics of liquid crystal. TFT-LCD is the first Liquid Crystal Display in human history whose display quality exceeds that of CRT. The function will be more powerful, which is unmatched by traditional small integrated circuits.
(4) Design: Glass products and plastic products have fundamentally solved the problem of large semiconductors and opened up potential applications for the application of small semiconductors.
(5) Ingenious process: In addition to the use of vapor phase, chemical vapor deposition (chemical vapor deposition) MCVD (molecular chemical vapor deposition) and other processes to form films, laser flame technology has also begun to be applied traditionally, not only making amorphous films, polycrystalline films, but also Single crystal films can be manufactured. Can make silicon film, can also make other II-VI group and III-V group semiconductor thin film.
(6) Wide range of application fields. Liquid crystal display based on TFT technology is a rich industry in the information society, and the technology can also be applied to the rapid growth of thin-film organic electroluminescence (TFT-OLED) flat panel Display Screen shots. .
