A DVR is basically a hard drive that can be connected to the computer and to other video sources such as a VCR. It has a tuner which captures the signal using a cable, antenna, or a satellite. The analog signals are compressed and converted into digital signals, which are then stored on the hard drive. A built-in MPEG-2 decoder converts the digital signal back into analog signal when it has to reach the television for viewing. Each DVR has an operating system within the hard drive.

There are several advantages to digital video recorders. They do not require a recording medium like tapes, as the data is stored on the DVR itself. Another main advantage is that the recording and playback can be done at the same time. Using this, even a live program on the TV can be paused, in the sense that the program can be recorded on the DVR and then viewed instead of the live program. However, the space within a DVR is limited, which is its main disadvantage. DVRs also have a live-TV buffer that keeps them in a constant recording mode for an hour or more.

Another interesting feature of DVRs is their search tool, which allows searching of a particular program by name of the program, name of the actors, or even by keywords. Some DVRs can be programmed to record some programs that have certain words in them. DVRs have recording capacities ranging from thirty hours to 320 hours. This also depends on the quality of the stored files.

The main categories of digital video recorders are TiVo, ReplayTV, and UltimateTV. Some of the top manufacturers of digital video recorders are LG, Panasonic, Philips, Pioneer, RCA, Samsung, Sonic Blue, and Sony. Prices range from $600 to $1,200 or more, depending on the brand, the model, and the options provided.

But surely this capacity to store shows on the digital video recorders hard drive is something of a disadvantage too doesnt it eliminate also the portability of the cassette tapes we used previously? Does this mean that we cant share shows that weve taped with our friends, or bring the recording with us when we visit their homes? On the contrary, digital video recorders are more share-friendly than ever. Shows stored on the units hard drive can be transferred to DVDs, offering you that same convenience or portability you enjoyed before. But digital video recorders can also allow you send the shows you have taped over the Internet, meaning that sharing recordings is more instantaneous than ever before.

The barrage of new technology that hits us almost every day can undoubtedly be daunting, but much of it is actually quite easy to master. You dont necessarily have to understand the nitty-gritty of a digital recorders innards to be able to enjoy the simple convenience it offers. And once you master the recorders simple operations, youll never go back to those burdensome cassette tapes.

Digital Video Recorder Record Your Favorite Shows With Ease is a post from: Technology News and Gadget Reviews | Nimbusmeta.com

Theres probably not a one among us that would deny that our police officers have a difficult job to do. With rising crime rates, it seems that they need eyes at the back of their heads in order to protect the communities they have sworn to serve. But thankfully, developments in technology have been successfully used to make their jobs a little easier, and to help keep us a great deal safer.

Digital video recorders are increasingly used in the stead of the their analog counterparts to monitor the goings on at all kinds of locations. From stores to police interview rooms, these devices are a more cost effective and efficient way to record the happenings in a variety of locations. With clearer, more detailed pictures, and the ability to record audio, digital video recorders are helping law enforcers more reliably identify and track down criminals.

There is a time honored question that asks who will police the police, and digital vide recorders are helping to address this important aspect of law enforcement also. To ensure the honorable behavior of its officers at all times, in 2003 the Yakima, Washington Police Department installed digital video recorders to allow them monitor the conduct of both officers and suspects. The success of this program has lead many other departments across the country to follow suit, helping to ensure that law enforcement is always carried out fairly.

Technology is undoubtedly a wonderful thing that enhances our lives in a multitude of ways. But it is possibly used to its very best advantage when it not only makes our lives easier, but helps keep us safer too.

Digital Video Recorder Doing Good Work is a post from: Technology News and Gadget Reviews | Nimbusmeta.com

With so many manufacturers and models available in the digital video market, you may find it confusing trying to choose the perfect one for you. Your choice will, however, depend on the features that you want and how much you are willing to spend.

The most important thing to consider is the format in which your videos will be stored, as the video format determines the video quality. Digital 8 otherwise called D8, Mini-DV, DVD and HDD are the main types of video format that digital cameras offer. Both D8 and Mini-DV are tape-based formats, with the Mini-DV currently offering the highest quality video format to consumers. The DVD format allows direct video recording onto a digital disk, while the HDD type uses internal hard drives where the video is recorded. As the tape format is slowly being phased out by major manufacturers, it is a good idea to invest in disk or hard drive based digital video cameras.

Digital video cameras also come with charged coupled device or CCD imaging sensor. Digital video cameras come with 1-CCD or 3-CCD features. Cameras with 1-CCD suffer from poor video quality, whereas 3-CCD cameras produce much better quality videos. Most professional camcorders use the 3-CCD technology, thus making them more expensive than the other models.

The optical zoom feature of the camcorder lens generally ranges from 10X to 20X. The choice of zoom depends on how close you want to get to the action. Some digital video cameras also allow still photography at various resolutions, and some camcorders offer both video and still photography features. Some digital video camcorders have in-built flash for low-light photography, while some video cameras come with a ‘Night Shot’ feature. Other popular options include external flashlights, external microphones and external storage devices that can be attached onto the camcorder.

Camcorders with longer battery strength is also recommended. Digital video cameras have battery life ranging from 4 to 8 hours of continuous shooting. However, using the zoom or any external devices reduce the battery strength.

All cameras nowadays come bundled with a digital video editing software. But if you are not satisfied with the one provided, you can always buy a better and more expensive editing software from Adobe or any other reputable brand.

Video camera prices today vary from $500 to $4000, with Sony, JVC and Canon being the more popular brands.

Digital Video Cameras – More Fun Than Ever is a post from: Technology News and Gadget Reviews | Nimbusmeta.com

Digital projectors play an important role in the formation of home theater systems. These projectors use resolution of SVGA standard i.e. 800600 pixels in expensive devices. Cost of digital projector is determined by its resolution as well as its brightness. If youre going to use it in large rooms or big conference halls its brightness should be from 1,000 to 4,000 ANSI lumens.

First digital projectors, Eidophor projectors were introduced in 1950. Eidopher projectors used an oily surface in a rotating disk with light shining through it and employed an electron beam to disrupt oil in a specific manner. Eidophor projectors were not able to produce colors. Nowadays there are several high quality models of digital projectors are available in market so Eidopher projectors are less common.

Following four technologies are used in digital projectors:
High intensity CRT

LCD projectors using LCD light gates

Texas Instruments’ DLP technology

Eidophor oil-film projectors (obsolete)

At present LCD projectors use Texas Instruments DLP technology whereas the high intensity CRT devices are suitable for enduring installations. Entire working of cathode ray tube digital projectors is like CRT television set. These projectors may be configured with one RGB color tube that has three colors red, green and blue with a single lens, one black & white tube with a rotating color wheel or three RGB color tubes with three lenses.

Projectors having cathode ray tubes are usually bulky thats why these are the best projectors for fixed installations.

LCD digital projectors are portable and lighter enough in comparison to CRT and can be easily shifted from one place to another. These are very much popular and available in various shapes and sizes. CRT and LCD digital projectors come under the category of transitive projectors.

Reflective projectors are the superior digital projectors that provide high quality images. These are affordable and offer next level of entertainment. Everyone can enjoy home theater applications with the help of digital projectors.

Digital Projector Guide- Some tips for Digital Projectors is a post from: Technology News and Gadget Reviews | Nimbusmeta.com

The term “big screen” is used to indicate a TV size larger than 40 inches in diagonal measurement. Until recently these are usually rear-projection screens, although we are seeing more and more flat-panel displays at competitive prices.

The appeal of Rear-Projection TV (RPTV)

There certainly is a great deal of consumer appeal for RPTVs these days. And it’s easy to understand. Part of it is due to the simplicity of the product. After all, what could be easier than getting a bigger TV? If you want a larger image with no muss and fuss, it can be purchased from any local big-screen retailer and delivered within a day or two.

Another the appeal of RPTVs is the impression created by big-screen retailers that RPTVs are cheaper than front projection systems.

Clearly there is a market for both types of home theater solutions. From a practical perspective your room size has a lot to do with determining which approach is best for you. If you don’t have a large viewing room, a 40″ to 60″ diagonal TV will probably be plenty. In this case, the rear-projection solution is more practical assuming you can fit the box into the space.

But if you want the large screen cinema experience and your room size will allow it, front projection is the way to go. Front projectors are made to produce screen images in the range of 70″ to 120″ diagonal or more. Once people realize they can get a picture up to four times the size for the same money as a good RPTV, it opens up a whole new world of entertainment possibilities.

How good is the Rear-Projection TV:

As noted above, the advantages of RPTVs are obvious. There is a wide array of products in different sizes and price ranges. There are usually several local showrooms in most areas. And they are simple to buy and install.
However, RPTVs have several limitations that front-projection systems do not. Among them are limited screen size, poor viewing angles, excessive reflections, poor aspect ratio management, and loss of floor space.

Screeb size is an obvious difference, but still worth thinking about for a moment. A 100″ diagonal front projection screen is four times the surface area of a 50″ RPTV. If you want to put real “theater” in your home theater, the projector and movie screen approach delivers it. RPTVs are just big televisions.
Digital Projectors

A digital projector is an electro-optical machine which converts image data from a computer or video source to an image which is then displayed on a distant wall or screen using a lens system. A typical resolution for a portable projector will be the SVGA standard (800600 pixels), with more expensive devices supporting XGA (1024768 pixels). The cost of a device is not only determined by its resolution, but also by its brightness. For use in large conference rooms the brightness should be between 1,000 and 4,000 ANSI lumens.

There are four competing digital projection technologies: high intensity CRT, LCD projectors using LCD light gates, Texas Instruments’ DLP technology and LCOS or liquid crystal on silicon. In 2004 and 2005, LCD front projection has been enjoying a come-back because of the addition of the dynamic iris which has improved contrast up to the levels of DLP.

There is a genuine market for both RPTVs and projectors for home theater. RPTVs are simple, but they have limitations in screen size and performance. Projectors and screens require some installation work, but once it is done you end up with a more dramatic theater experience.

The bottom line is this: if you are looking at digital RPTVs and your viewing room can accommodate a 90″ or 100″ screen, don’t overlook the possibility of a projector and screen instead. If you can afford a digital RPTV, you can afford a projector. And dollar for dollar the projector will often deliver the maximum “wow” factor for the money invested.

Does that mean that the very progress that brought us the wonderful world of digital electronics is also digging us into a deeper and deeper hole of energy dependence and spiraling monetary and environmental costs? It doesn’t have to be that way. Business and the environment do not have to be at odds. There is, in fact, a green electronics movement that seeks to make our beloved electronics more energy efficient and environmentally friendlier. The movement covers the entire spectrum from huge international conglomerates pledging to recycle, reuse and conserve, all the way to electronics being more energy-efficient and either bio-degradable or easier to recycle, thus reducing what is now called “e-waste” from millions of tons of landfill to reused and recycled resources.

Saving energy and recycling makes perfect sense, and it’s no surprise that there are now companies devoting themselves to green electronics and energy sustainability. After all, it’s good PR and makes economic sense. But it goes farther than that. There are now even companies that sell both digital electronics AND renewable energy products. It’s easy to see how a firm belief in renewable energy, conservation and sound energy policies may drive an environmentally conscious business owner to sell items like solar and wind energy products as well as digital electronics made by companies that have realized that business and society are interdependent and thus embraced green technology.

What is “green technology?” It can be products certified for low emissions, products certified to be more energy-efficient (like the Energy Star pledge and standard), or products using solar chargers or other energy saving technologies. It can also mean support of companies that are actively “going green” by increasing recyclable content, removing environmentally harmful substances, using renewable energy in the production cycle, and supporting environmental conservation causes and projects.

Why would companies go green? Because it’s not only the right thing to do, but also because it’s an increasing competitive advantage to be seen as a green company that cares about the environment. Just like a lot of consumers reject pesticides and insist on organically grown food products, more and more consumers insist on buying green, energy-efficient technology from companies that care. It’s good to know that megahits like iPhones and Wii gaming consoles are made by such companies.

What we’re seeing here is really an inevitable, accelerating trend towards smarter, greener and more efficient and conscientious consumption. We all must fight waste and embrace clean, sustainable, renewable energy.

With a video capture feature on your camera, you can take low to medium quality video footage using your digital camera. All cameras with video capture are not created equal, though. Here are some things to check on before buying a camera with video capture:

1 Sound

Does the camera support sound? If so, does it capture it through a built in microphone, or does it have an input for you to plug in an external microphone?

2- Video Quality

There are two main factors that determine video quality resolution and frames per second. The higher the resolution, and the higher the number of frames per second, the higher quality the video.

3- Video format

What format is the video in? Ideally, it will be in a standard, easy to edit format, such as MPEG. Some cameras use proprietary video formats, which means that you can’t edit your videos with most editors. Windows Movie Maker, which comes free with Windows, is a great editor to use for most generic video formats.

4- Video length

Some cameras limit the length of video clips you can take, often to 30 seconds. This can be a great aggravation. The better cameras allow you to take as long of a video clip as your camera’s memory can hold. Of course, you can add a larger memory stick to take a longer video clip. You can now get memory sticks up to 2 GB or larger.

5- Zoom

On most digital cameras, you can use the zoom when taking video footage. However, you can generally only use your optical zoom, not your digital zoom.

In choosing a digital camera take into account your basic needs and what you plan to use the camera for.

Digital camera types

It doesnt matter whether you’re shooting film or digital images there are basically three types of cameras. There are point and shoot cameras, prosumer cameras and professional quality cameras.

1. Point and shoot cameras operate automatically. They do everything for you except for framing the subject. Exposure is decided by the camera as well as whether a flash is needed or not. All you need to do is to point and shoot.

2. Prosumer Cameras. This camera is a step up from your typical point and shoot because it allows the photographer not only to shoot in a fully automatic mode but also to have control over various aspects of the exposure. They typically have various modes including portrait mode, a close-up mode, action mode, and landscape mode.

Resolution

It doesn’t matter what sort of camera you decide to get you will have several decisions to make regarding resolution of the camera.

The salespeople of most electronics superstores are quick to tell you that the most important thing to consider when buying a digital camera is how many pixels there are. Now while it is important it is not the end all of digital image quality. Pixels are tiny squares and in some new models they’re starting to use other shapes as well. The more pixels you have in your image the sharper the detail of the image will be.

Most current digital cameras on the market today will produce an image with more than 4 million pixels. That’s enough resolution to easily print images up to 8 x 10 with good image quality. Is not likely that you will print images larger than 8 x 10 and so most of these camera should meet your needs.

Try various digital cameras before you purchase

There is a wide selection of digital cameras on the market with various image qualities even though they may have the same number of pixels. There are different kinds and sizes of image sensors, which is the chip that actually records the picture. It is recommended that you take a memory card into the store with you so that you can put it in each camera and take sample photographs that you can then take home to view on your computer to compare.

The technology is constantly improving and digital cameras will be constantly changing. Dont be surprised if several months after you purchase one there is one that is new and better with more pixels. If you take the time to choose a good quality digital camera which makes good photographs you’ll be able to enjoy digital photography for a long time in the future.

If you do make the move into digital photography remember this. Many people using digital cameras simply put their photos on their computers and never actually make prints anymore. It is easy for these photos to get lost and therefore it’s recommended that you print special photographs for generations to enjoy.
