You will already be familiar with standard definition television and you will have heard about high definition, but what about 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?
There has never been so much choice of HD programmes and movies. Both Sky and the BBCs and ITVs Freesat provide multiple channels of HD. Alternatives to these are Blu-Ray, HD downloads on the Web, or On Demand services from Virgin Media or Tiscali. It might appear as if there is a lot of choice but it still isnt possible to watch all channels in HD. If you arent prepared to pay a monthly subscription fee then Sky isnt an option and your choice will be narrowed considerably because they have the most choice of channels. Furthermore if you dont want to buy or hire Blu-Ray Discs the choice is even more limited leaving 2 channels of free HD channels on Freesat or a small amount of On Demand programmes or films from Tiscali or Virgin Media. Because of these limitations on available HD programmes the television manufacturers believe that there is a need for Near High Definition television.
What is a Standard Definition picture.
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.
The movement on the picture of a television is created with 25 still frames being displayed successively every second. Each frame is split in to 2 fields that each contains half of the lines that form the picture with the even lines in one field and the odd lines in the other field. The combining of the 2 fields from each frame is called interlacing which produces a full frame. The odd and even fields are shown alternately as the picture is painted or scanned on the screen each at a rate of 25 times per second. The combined display rate of the odd and even fields is 50 times a second which is referred to as 50 Hz.
The number of pixels that make up a picture is known as the resolution. So a television with more pixels will have a higher resolution. Generally the higher the resolution is on a television the sharper the image that it can produce. Televisions with a high resolution are known as High Definition televisions.
High Definition broadcasts in the United Kingdom are at 720P (1280×720 pixels) or 1080i (1920×1080 pixels). If you want to experience HD TV programmes you will need a TV set that is at least HD Ready with a resolution of 720P (1280×720 pixels). There are also higher resolution televisions than HD Ready TVs known as Full HD Ready 1080P (1920×1080 pixels) but there are not any 1080P broadcasts available at present. To benefit from this increased resolution you will have to rely on Blu Ray discs or HD down loads from the web.
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.
So how are near High Definition images created from Standard Definition? A process known as upscaling is used to create a near HD image. But what is upscaling?
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.
The upscaling process is done by the TV using a digital video processing chip which interlaces the input signal and then the advanced algorithms and filters interpolate the picture by creating the missing lines and pixels that are required to fill the screen. This process matches the input resolution with the TVs native resolution.
The quality of the upscaled image thats displayed will be determined by the quality of the upscalers processing chip, other electronics and the screen. The source signal quality will also be very important in determining how the internal electronics manage the picture and how they well they display it.
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.
Whilst advanced software algorithms are able to estimate what the extra pixels should display in the upscaled picture it isnt able to turn a Standard Definition image in to a genuine High Definition picture.
Toshiba has a near HD upscaling technology called Resolution + which they incorporate in their ZV range of televisions that they say will vastly improve the quality of a Standard Definition picture. They use the powerful upscaling cell processor that is used in the Sony PS3 which upscales any image to 1080p resolution.
The image cell processor compares adjoining images which it merges the detail of to improve the image detail. This gives an image that is lucid with rich colours. The extra detail means the image has sharp edge detail with noticeably reduced 3 D noise. Also the blue and green colours are enhanced to compensate for potential clarity losses that can result from upscaling. Also the contrast is improved in dark scenes but the light areas are still as bright. The combined effect of all of these enhancements is that an SD picture is crisper and with sharp edge detail and better texture whilst the flat areas are unchanged.
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.
Toshibas upscaling DVD player is the XDE model which isnt the same as other DVD upscalers that are available because it deinterlaces the picture and then upscales the Standard Definition 576 lines to a 1080p near HD resolution. As with the Resolution + on the Toshiba ZV range of Televisions the picture is enhanced to give more detail, more vivid colours, and improved contrast using the same techniques as detailed above.
So should you buy a Near HD TV or DVD Player?
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.
The Near HD TVs offer the ultimate flexibility with the ability to enhance almost any source. As more HD options become available either chargeable or free the TV is capable of receiving and displaying 1080P sources so you wont need to upgrade your TV. Toshiba is the only company that offers Near HD TVs and a DVD Player but others will follow soon.

When shopping for a new television, it is important to remember that a cheap TV is not always the best choice. Think about what you hope to get out of your television before committing yourself to one of the cheapest TVs that are unlikely to hold up over time.
Brand name televisions are almost always going to be more expensive than off brand and unbranded LCDs and plasmas you might see online. The brand names cost more due to the fact that their brand name is recognizable. Cheap televisions can survive by constantly creating new brand names so that no one can recognize a new television as an inferior product they bought years ago.
Buying a Cheap TV: When’s and Why’s
Obviously, if reliability is a priority, then a cheap television is probably not the best buy. A brand name TV set should last a good, long time without any major hassles for the customers. It is important to remember, though, that brand names doesn’t have to be synonymous with expensive! A savvy shopper will be able to find cheap brand name televisions without any frustration.
Cheap TV sets aren’t entirely worthless, however. A TV that only lasts a few years might not be a downside when you’re in a situation where you don’t plan on using a cheap television for long. Rather than buy a new television that’s going to be disposed of soon, buying a cheap, low quality TV could be the perfect solution. For instance, college students who’ll soon be moving out of the dorms might prefer a shorter-lived television that can be disposed of guilt free in a few years.
Cheap LCD TVs: Worth the savings?
LCD or plasma TVs can be expensive. However, the higher price might tempt some to unwisely cut costs and purchase an inferior product. Because cheap plasma TVs and cheap LCD televisions are cutting back on manufacturing costs, the quality is almost always significantly lower. When customers buy an offbrand Plasma TV, they can expect washed out colours and other problems.
This is because the ability for these types of televisions to display dark blacks and other deep colours is dependent on the quality of the manufacturing. The cheapest LCD TVs and the cheapest plasmas are going to suffer due to the cost cutting taking places in the overseas factories where they’re made. There might be some mileage to be found in pubs or other venues that require multiple cheap TVs, but most people will get more value out of a slightly more expensive name brand television.
Overall, most customers will have a better experience with name brand televisions compared to cheap TVs. However, there may be certain situations where buying the cheapest television available will make sense. Just take a little bit of time and review what you need before making a purchase and the decision should come easily.
