In 1911, a Russian scientist created a television system that used a mechanical mirror-drum scanner to transmit very crude images to the receiver. Moving images were not possible then.

In 1928, a Scottish engineer demonstrated the world's first colour transmission.

Now Toshiba has brought liquid crystal display television into a new era with Meta Brain Pro, the latest motion enhancement technology, under the brand name Regza.

And with all eyes focused on the final stages of the World Cup, it might provide a welcome addition to football fans wanting a crystal clear image of the final.

Regza is the first unified brand for Toshiba's large-screen flat panel televisions. Meta Brain Pro stands out, according to Toshiba, because it incorporates several advanced technologies to provide sharper and better-looking pictures.

The Meta Brain Pro achieves real 3D effects by analysing each pixel on each frame and independently adjusting the contrast, colour and brightness of the pixels to achieve the best balance. Noise reduction in moving pictures is achieved by the use of Motion Adaptive DNR, which takes into account the extent of the whole picture movement.

According to Toshiba, extending scanning and adjustment of the picture movement achieves a clearer and cleaner image on screen. A process called Motion Adaptive Cross Colour Suppression essentially detects the amount of motion in each scene and automatically varies the correction level to produce the cleanest image.

Conventional luma enhancement methods tend to overshoot and undershoot the edges between objects and background, which can cause an artificial outline effect.

Meta Brain Pro carefully monitors and controls the luma transition, so the overall picture is reproduced with clear details.

Meta Brain Pro also uses Intelligent Motion Adaptive De-Interlacing to achieve a smoother progressive picture.

It performs the de-interlacing by adjusting the scan line on a per-pixel basis, with additional reference to the amount of movement of each pixel, brightness and noise, as well as the extent and direction of the whole picture movement.
