Uses and Benefits of Video Test Pattern Generators

Video test pattern generators provide a convenient and effective way to calibrate, test and troubleshoot video display devices such as HDTVs, projectors, LCD (liquid crystal display) screens and CRT (cathode ray tube) monitors for the ideal viewing experience.

Specific patterns are produced by the video test pattern generators to determine a variety of performance criteria, including: video resolutions, brightness and uniformity, purity and color saturation, linearity, edge geometry, sharpness, stability, etc. By comparing the video input pattern to the video output on a display unit, it is possible to determine how accurately a monitor displays the video it receives and if any defects can be rectified. Some video test pattern generators also allow a user to test digital and/or analog audio signals through generated frequency waves. Using the corresponding video cable needed, simply connect the video test pattern generator to the supported display unit to run the test patterns on the screen. No other video source, such as a computer, DVD player or set-top box is needed for the testing process. If multiple display units are to be compared, the use of a video splitter can ensure that the same pattern is displayed on all desired monitors and subsequently calibrated so that the video output is identical on all screens.

Three of the most common video test patterns are: color bars, grayscale charts and crosshatch, with each serving a distinct function. Several variations of the color bar test pattern exist, with the most well-known being the SMPTE color bar, which are used to test analog NTSC video. All color bar test patterns serve the same purpose of testing and calibrating color saturation, balance and brightness. Most grayscale charts consist of a gradient of monotone bars with the goal being to obtain a smooth range of neutral grays from pure black to white. Adjustments can be made to brightness and contrast to achieve the optimal display. Crosshatch patterns are used to check and calibrate centering, aspect ratio, convergence, and both vertical and horizontal linearity. Other test patterns can range from focusing on one or two specific issues to universal patterns that cover most key aspects.

Most video test pattern generators are compact, portable devices that allow easy field calibration, testing and maintenance of many applications such as: production line quality assessment; studio equipment for both installers and users; television sets by TV engineers or technicians; digital signage configurations with extenders, switches, splitters or video wall processors; and discerning home theater users. High-end models tend to support multiple video signal types while lower-end models offer a more limited and specific selection. Video Products Inc (VPI) offers a wide selection of video test pattern generators that can fulfill the needs of varying applications.

VPI’s MONTEST-HDMI and MONTEST-HDMI-LC respectively provide a high-quality and low-cost option for testing HDMI or DVI display units. The low-cost unit can generate 34 video test patterns, 48 timings and a single audio tone. In comparison, the MONTEST-HDMI provides 39 distinct test patterns, 35 resolution and timing settings, and a range of analog and digital audio signals via a built-in sine wave tone generator. It can also be controlled via the IR remote control or RS232 in addition to its front panel buttons. Both units can test for HDCP compliance and support HDTV resolutions up to 1080p.

The MONTEST-LCD signal generator supports analog computer monitors, LCD displays and video projection systems with the following four connectors: VGA, MAC II, SUN and RGHHV for BNC. It can generate four video patterns with 16 colors and intensity control, and over 100 frequencies that cover a wide range of monitor types.

The MONTEST-HDSDI can generate eight video test patterns and seven timings up to 1080p resolution at full broadcast quality, making it ideal for testing and maintaining studio equipment such as monitors, cabling and recording equipment. It also supports single-tone audio testing and dual SDI output for side-by-side comparison of displays.

All encompassing, the MONTEST-DA supports both analog and digital video signals, including: HDMI, DVI, NTSC, PAL, component Y/Pb/Pr, S-video, VESA, and more. It not only provides a variety of video test patterns, but also allows a user to play stored video and audio files from an embedded 80G hard drive. Remotely control the unit via its RS232-port. Supporting stereo audio test signals, DDC2B, and HDCP, the unit can scale a source to fit a display based on its EDID data. The MONTEST-DA is an ideal, comprehensive solution for applications that need to test, calibrate and maintain various display types.

Video test pattern generators are necessary for achieving optimal displays in many different settings and VPI’s range of MONTEST video test pattern generators can help both consumers and businesses achieve the highest quality their display units can deliver.

What is behind VoIP Technology

This is the back end article. It does not tell you what you need to do to make something operative. On the other hand, it talks about how the things work in the technological world. Therefore, dont expect me to entertain you. You can surely expect me to increase your knowledge levels. How many of you know about the technology called SIP? Most of us use the technology and call ourselves tech savvy people but what do we know about the back end processes going on? It is surely not enough to know about how to use the technology. It is also essential to get to know the workings behind what you can see. Take a microscope and look for that. Only then, you are eligible enough to call yourself a tech save person. Read on and you might change your profile to a tech savvy person on the personal level.

First of all, let me assert that SIP is a technology and not software to be used. It is one of the biggest platforms to use the VoIP calls made from the internet. They are much cheaper and with voice quality well assured. In the ordinary persons language, calls are not made from the phone. They happen based on the internet connections in the form of transference of digital signals. It is the upper level of technology where the distances between the loved ones are reduced enormously.

The next appropriate question that arises is where does SIP Softswitch lie? Before that, let me answer the question as to what is softswitch? It is device by which you can connect your basic telephone to internet. It connects the two networking systems and this is the exact place where the signals for incoming and outgoing calls are controlled. Its basic function is to analyse the nature and destination of the call and send them off accordingly. While doing all this, it has to compulsorily adjust the properties of the signal.

When you do the SIP calling, softswitch converts the PSTN signal; let them carry the IP properties making it appropriate to connect to SIP. The same procedure is followed when you connect the SIP system to PSTN number.

This basic function makes it a favourite of many. Various companies, individuals and private firms are using this technology to reduce their costs of their businesses. It is quite helpful for many and can prove to be equally useful for you too once you start using it.

Technology Of Mobile Computing Changes The Way We Evolve, Rapidly!

In the new information age all people are connected on the Internet, this swiftly feeds innovation on all fronts of the modern society. Computers are used In third world countries more often every day. Not only fixed desktop computers, but specifically mobile computing devices. These new forms of communication help people in underdeveloped countries connect, share and exchange knowledge. What has propelled us forward, and still is pushing us in new stages is knowledge creation and sharing. In fact , this is what separates us from animals, our ability to communicate on superior means. In the old days knowledge was shared through books. A privileged few who had access to libraries and reading/writing abilities could learn, create and share new knowledge with those that are born after them. Through these means, we as civilizations have evolved over the centuries.

Consider what kind of effects mobile computing technology has on our means to learn, create and share knowledge. No longer a selected privileged few have access to libraries, now almost everyone on this planet has access to Internet, and fast amounts of information it holds. Given, that not everybody has reading/writing abilities as of today. Still, we are making huge advancements towards creating individuals who are smart, connect and share/integrate their insights, to create new knowledge. This knowledge has been building over the past thousands of years and shapes our world today. The past few decades our technological breakthroughs are expanding exponentially. Not so long there were people who thought it was impossible to land on the moon, yet today we take this for granted. What about cloning animals? Although there are some ethical issues involved concerning cloning, my point is this: The pace at which we learn and evolve as a species is growing rapidly!

The reason I am so excited about mobile technologies, is that smart phones, tablet pcs and laptops are a means to create and share knowledge at speeds we cannot even begin to grasp. Not only are more and more individuals connected, the geographic boundaries are virtually broken. A very smart individual from Africa, can connect with an European to create new knowledge. This diversification of social network ties, provide means to connect individuals with different cultural backgrounds, worldviews and thought processes. The unique insights that evolve from these kinds of connections, could create the Nobel prize winners of tomorrow. Call me an optimist, but I strongly believe mobile computing technology is shaping our future, to become even more brighter than we can imagine today.

When we take one step back in our minds eye a couple of hundred years, there is no doubt. Learning, creating and sharing of knowledge has been going faster, and faster each year! No one knows what the future may hold for us exactly. Only some amazing technological breakthroughs will come, of that I am sure!
