Every one is already familiar with standard definition television broadcasts. Most people have also heard of high definition but few have heard of Near High Definition.

Near High Definition is a new feature that television producers have created for raising the picture quality of Standard Definition (SD) broadcasts to a claimed Near HD quality.

Is there any need for a Near High Definition Television?

Whilst there is an increasing amount of HD content available via Sky and Freesat it isnt possible to watch all available programs in High Definition. The only other sources of HD are Blu-ray and downloads from the internet. Furthermore if you arent prepared to pay a monthly subscription or pay for Blu-ray discs then the choice is limited to Freesat or a small selection of On Demand programmes and movies from Virgin Media or Tiscali. With such a limited choice of High Definition content the television manufacturers believe there is a case for near High Definition televisions that upscale the picture to allow you to make the most of your HD television.

Standard Definition Broadcasts

A TV picture consists of 1000s of little cells known as pixels. Broadcasts in the UK use the PAL system which in standard definition has 576 horizontal lines of 768 pixels across the screen or 768 x 576 pixels.

When a television picture is broadcast the moving picture is broken down in to frames. These frames are actually split in to two half fields A and B, where the A field consists of the odd lines and the B frame consists of the even lines. This type of picture is known as an interlaced image. When the two fields of each frame are combined or interlaced they create a complete frame as each field is alternately scanned or painted onto the television screen. Where the odd and even fields are displayed alternately each showing 25 times a second or 50 times a second when displayed alternately together, hence the term a 50hz picture.

The total number of pixels that a television screen has is known as the resolution. A high resolution or High Definition (HD) picture has more pixels than a Standard Definition picture. HD TVs will generally have a sharper picture, or will be capable of displaying a sharper picture, than a Standard Definition TV.

At present UK broadcasts of HD content are at 720p (1280 pixels x 720 pixels) or 1080i (1920 pixels -1080 pixels) resolution. To benefit from this you will need a television that is at least HD Ready with 720p (1280 pixels x 720 pixels). Alternatively you can buy a Full HD Ready 1080p (1920 pixels x 1080 pixels) television although there arent any broadcasts that will allow you to benefit fully from this specification. The only source that is available is either Blu-ray disc or downloads via the internet.

The quality of the picture of a Full HD 1080P TV compared to an ordinary SD TV is around five times greater than a standard definition and hence the reason for the terrific image quality.

On TVs that have Near HD they use an upscaler to transform an SD picture into 1080P.

An Upscaler is also referred to as an Upconverter which converts the resolution of a source signal. Upscaler can convert low resolution images to a resolution that fills the screen. When a Full HD 1080P TV, with a resolution of 1920×1080 pixels, receives a signal from a DVD or a Freeview broadcast of 768×576 pixels it has to upscale the image to fill the screen. It does this because the two resolutions are different and if it didnt upscale the image then some parts of the screen wouldnt be filled by the picture and it would be smaller the screen.

HD televisions have a video processing chip that upscales the image so that the incoming picture signal has the same resolution as the native resolution of the screen. This is done by first interlacing the picture which allows the digital algorithms and filters to interpolate the image by adding extra pixels and lines.

The ability of a TV to upscale an image is dependant on how good the source input and the quality of upscaler chip. The quality of upscaling chips varies from TV to TV as does the quality of other internal components and the actual screen which affect the quality of the picture displayed.

All LCD and Plasma televisions have an upscaler to accommodate the different resolutions of various sources so that they fill the native resolution of the screen. What is different about a Near HD televisions is that they use a much more powerful processor in the upscaler that allows them to do a much better job than other televisions.

The higher quality upscaling chip employs sophisticated software algorithms that approximate how the additional created pixels should look in the upscaled image. However this approximation isnt as good as a Full HD sourced image where the TV doesnt have to guess what the extra pixels look like. Any approximations will sometimes be inaccurate but an educated guess.

The first and only company to launch Near HD TVs at present in the UK is Toshiba with their Resolution + ZV TVs. These will produce a significantly better picture from a SD source than other standard TVs. This is done by means of a Sony PS3 cell processor upscaler which upscales the picture to 1080p.

The enhanced picture is achieved by the cell processor comparing adjacent image frames which it then combines the pixel detail of to enhance the definition. The picture quality is clearer with sharper and richer pictures. The detail is enhanced which sharpens the edge of images and reduces 3D noise. The colour palette is more natural due to enhancement of the blue and green shades minimizing the loss of clarity that upscaling can often cause. Contrast Enhancement results in dark areas becoming darker whilst at the same time the bright areas maintain their brightness. This results in Standard Definition images being crisp and rich with sharper edges and improved texture but the flat areas are not changed.

Upscaling Near HD DVD Players

A DVD players with near HD picture processing isnt the same as one with progressive scan which converts interlaced images into full frames by combining the two fields that make up the frame so that they are both displayed at the same time. This results in more fluid motion, improved vertical resolution and no interlace artifacts such as flickering between lines. Progressive scan uses the existing two A and B fields pixels from each frame to create a full frame but it doesnt generate additional lines or pixels like an upscaler does.

There is a number of upscaling DVD players presently available on the market. These machines dont deinterlace the image before upscaling it from SD. Only Toshiba currently has an upscaling Near HD DVD Player, the XDE model, that upscales the SD 576 line picture to 1080P lines Near HD. This is done in a similar way to the Resolution + TVs from Toshiba where the picture is enhanced so that it is more detailed with lifelike colours and better contrast levels.

Is near HD worth buying?

Obviously a 768 x 576 image isnt as good as a 1,920×1,080 image and no amount of digital processing will make them the same but a good upscaler is able to produce something that is closer. If you arent prepared to purchase films on Blu-ray, or pay a monthly subscription for high definition channels, and you arent happy with the limited HD content that is available on Freesat then a near HD product is the right choice. It isnt as good as a genuine HD 1080p source but it does deliver noticeable improvements in the picture quality on virtually all content including 480i, 576i, 720p (DVD, Standard Definition TV broadcasts and Video Games) all of which it will upscale to 1080p.

A further benefit of purchasing a Near HD TV is that if more free HD content becomes accessible in the future or if you subscribe to Skys HD service then you will not need to buy a HD TV because the Near HD TVs are also Full HD 1080P TVs. In the United Kingdom the only Near HD products that are currently available are made by Toshiba but other products will be launched by alternative manufacturers soon.

Technological advances has catapulted photography onto an whole new level. Advanced techniques and equipment are always on the horizon.

35mm cameras use 35mm film which is both suitable for still photography and motion pictures. The 35mm camera was unveiled to consumers in 1934 and reached huge popularity by the late 1960s.

The typical number of exposures on a roll of 35mm film is 36. However, the number of exposures can vary depending on the needs of the photography and cost constraints. Disposable cameras can be found in 6, 8, 10, or 15 exposure quantities.

The first still camera to become popular with the public, using 35mm film was the American Tourist Multiple, which began selling in 1913. The new invention cost a lot of money for the times. It was the 1925 Leica 35mm camera however, that really set the seal of success on this type of product.

The Leica quickly caught on amongst photography enthusiasts. Its compact size, quality glass and German craftsmanship all contributed to the success of the 35mm Leica camera. The Leica became the standard for professional photographers, fashion photographers and photojournalists.

Film cartridges were not introduced until 1934, when the Kodak Company released the Kodak Retina. The Kodak Retina was manufactured in Germany. In 1960, photography would take another industrial leap the Single Lens Reflex camera (SLR).

This was the beginning of the Single Lens Reflex system, a technology that went on to dominate photography. This type of camera proved more user friendly with functions such as a viewfinder, focusing screen and motor drive to automatically move the film on.

Traditional 35mm film camera sales took a big hit when digital cameras first hit the scene. But with the advent of Digital SLR cameras, the 35mm seems to have weathered the storm and is regaining its popularity.

Today, the camera and film market is shared by Kodak, Ilford, Fuji, Nikon, Olympus and Canon. The technology will, no doubt, evolve once more into territory not even thought of as yet but there will always be a place of affection for those early cameras that people grew up with.

When it comes to television, more and more people prefer having HD televisions in their living rooms instead of SDTV, which is now fast becoming a thing of the past. SDTV or otherwise known as Standard Definition Television, which we witnessed rise as far back as 1970’s refers to those television systems which are not enhanced or not high definition.

HD television is topping the sales charts at the moment because of the apparent advantages it offers the viewers compared to the ragged visuals emitted by SDTV. The smoother and sharper images coming from HD television gives the viewers more pleasurable viewing experience which led to the phasing out of SDTV.

You maybe wondering why television shows do not look good when you are using your SDTV or when you are playing your video games. This is because television networks and makers of cool gadgets like iPod, Xbox 360, Playstation, AppleTV have agreed to deliver media in HD Television format.

HD Televisions enjoy preference in the latest gadgets that can be attached to it. This is with reference to game consoles and media players such as Xbox 360, Sony Playstation, Nintendo Wii, iPod and AppleTV. No wonder members of the family from all ages prefer this unit.

Well, the fact is HD Television would have been able to make it really quite well in the market even without the television networks and manufacturers of the latest gadgets backing it up. The reason is that the thing is good in itself. In fact, it features capabilities, which have been long anticipated by avid TV users from all over the world.

HD television has features like simultaneous browsing of channels or TV and video at the same time. It goes with quality speakers that can bolster the whole viewing experience. And for those who are lazy to customize colors or sounds, it can quickly adjust everything to cater to everyone’s preference. There are other features of HD Television that cannot be found in SDTV.

The best thing about HD Television is that it gets better video quality if it is in wider screen unlike your SDTV which appears the same in smaller or wider screen. Hence, in getting a HD television, here are a few things that you should remember:

It is advised that you get an HD television with the fastest bit rate and proper connector cables. These are the things which you should not dispense with since this affects the quality of the video on the user side. As to question among which between SDTV and HD Television is better, no doubt the latter is the best.

You can buy an HD television virtually everywhere. However, there maybe variation in prices due to features, sizes, brands and quality. If you are looking for an HD Television at a reasonable price or with discounts, then I have a good list for you and where to find it. The link below will direct you to the right place. I am certain that you will find the one suited for you with their great selections of HD Television.
