K Resolution – Fourfold full HD

Description: 4K Resolution – Fourfold full HD

In 2012, 3D would not be the only focus for TV-panel developers. 2D presentation will undergo a significant progression. 4K Resolution, or Quad-full-HD, will see its way to succession. The 4K panels display can achieve 4,096 x 2,160 pixels, which is four times more than regular full HD resolution (1,920 x 1,080 pixels). Panasonic has already presented a prototype of the 4K panel and 152-inch screen, which costs a total 500,000 Euros (that’s about 2 million in MYR). Handier and more affordable devices could definitely be expected in the coming year. They are also necessary to present 3D without glasses, which is only possible when several pixel on the screen jointly represent one pixel of the 3D image (see picture below). Right now, content for the (mega) high-resolution display is still unavailable widely. This, of course, may also change. YouTube is already offering special videos with 4K resolution. Britain’s BBC would like to go the extra mile during the upcoming Olympic Games in London by planning an 8x full HD broadcast. That, however, will only be for public viewing with special projectors – suitable TVs will not be available by then still.

Active polarisation – polarizer in full HD

Polarizer technology is being implemented into more and more 3D TV sets lately, mainly because polarised glasses are more convenient compared to shutter glasses and are theoretically compatible with any polarised 3D TVs. However, current uses of polarisation also has a great technical disadvantage, as the image is filtered line by line for the right and left eye. Thus, the resolution of a 3D video is halved, resulting in no traces of full HD. To counter this, upcoming 3D TVs with active polarisation will integrate the image change method that shutter glasses are known to have. The filters will polarise the light for the right and left eye in full HD.

Pol-filter with shutter technology

Televisions with active polarisation combine the advantages of the polariser and shutter technology together. The 3D-image is transmitted in Full HD.

Short shutter lag

The TV switches the polarisation in a quick change.

Polariser

The polariser layer switches over quickly and in this way generates one image for the right eye and one for the left eye.

Covenient glasses

As the TV processes the 3D images, passive polarised glasses are sufficient.

GBit-WLAN – Wireless high-speed network

If you wish to connect a Blu-ray player, video game console, media centre and a NAS server all without the oft inconvenient LAN cable, you’re rapidly impinging upon known wireless technical limits. Though current WLAN standards are capable of sending a HD stream, once online family traffic kicks in only shortfalls will arise. This would not be a problem with the coming GBit WLAN. Devices then can roughly transmit with a data transfer of more than 1GB/sec as per the new IEEE 802 Standard, and a transfer rate of up to 6.9GB/sec is planned for 2013. Even if the net throughput currently only amounts to half the amount, it would still be fast enough for the wireless connection of all communication devices. For GBit-WLAN, one reallt relies on optimisation rather than new technology – a more powerful modulation, great frequency bandwidth, and more streams to transfer and receive data. Only by increasing the modulation from 64 QAM (Quadature Amplitude Modulation) to 256 QAM, the throughput can be increased by 33%. Furthermore, the radio channels expand from 40MHz to 160MHz, with transmission taking place in the 5GHz range with up to eight antennas – broadening the radio channels could lead to massive distrurbances in other WLAN routers because only two networks with 160MHz running simultaneously is possible. The MU-MIMO technology (Multi-User Multiple Input, Multiple Output) is an interesting advancement. This technology enables the distribution of different data to several clients at the same time – in an optimum case, there are no breakages in the transfer when many approach the WLAN. First such devices are coming in mid-2012 at the latest.

More antennas

New routers will transmit with 8 antennas in the range of 5-GHz.

Multhuser-MIMO

The router recognises several clients and can simultaneously provide data optimally at the same time with the help of MU-MIMO.

3D without glasses – the third generation of 3D

In 2010, 3D shutter technology was the first pathway for bringing 3D to home television. Last year, almost all manufacturers rely on the cheaper polarised glasses used in theatres instead. In 2012, glasses-less 3D TVs could be starting out and gaining its own momentum. Toshiba has already introduced the ZL2, which can present 3D without glasses at 720p resolution. The image is optimised to nine different viewing angles in front of the device. Though these overlap, double images can be generated via and interface. A layer of jelly-like lenses is present in front of the LCD panel to reflect the images in all zones. The disadvantage to this technology is that it requires nine pixels on the panel to radiate a point of the 3D image in all zones. Thus, the panel has to be able to display at least at 4K Resolution, which is still very expensive at the moment. The ZL2 now cost around 8,000 Euros – almost $10,785.

Smart-TV – remote-control apps

Smartphones and tablets are turning into universal remote controls of sorts via apps in 2012 because, thanks to Smart TVs, all new televisions have WLAN connectivity which allow smartphones to connect to them. They could replace the infrared interface of standard remote controls in the long run. It is also applicable to TV sets which aren’t Smart TVs themselves. An adaptor can be connected via Bluetooth to the smartphone which input will be translated into infrared, thus transferrable to the TV. Through this way, the apps will also solve the problem Smart TVs face with standard remote controls, as website URLs are hard to type in using the standard remotes. Smartphones, on the order hand, can display a virtual keyboard. Manufacturers of these devices mostly provide the previous apps and are specially adapted to these devices. It is advantageous when, say, Philips app. You’ll need a lot more apps for devices of different companies.
