Вот немного про технологии Томсона. Скопировал на диск, откуда не помню.
Thomson – Hi-Pix
Thomson’s picture technology will debut on its Scenium 4 CRT
TVs, due for launch in September. This 100Hz processing mode is said to offer ‘high-resolution’ pictures, increasing the amount of visible detail as well as improving colour reproduction. How is this achieved? Hi Pix takes the original video signal, which has an average bandwidth of 3MHz (corresponding to around 320 phosphor dots per horizontal line) and increases the bandwidth to 8MHz (по другим данным до 16 MHz и увеличивает разрешение с 320 до 1400 точек на линию) using a new 100Hz processing algorithm. This in turn increases the dots per line to over 800 – over twice their natural amount.
Hi Pix is also said to produce more vivid colours by doubling the number of colour samples. The digital processing in standard 100Hz TVs uses the 4-1-1 system, which samples the black and white part of the signal (known as luminance or Y) four times, samples the red (U) component once and the blue (V) component once. Hi Pix takes two samples of the red and blue components to create the 4-2-2 system, which Thomson describes as ‘broadcast-quality’.
Thomson – Hi-Focus
Another of Thomson’s picture processing modes is Hi-Focus, featured on its current range of TVs (such as the 28W201S). This advanced 100Hz mode claims that it can improve picture quality from a poor analogue TV feed, working to remove echo and interference. The signal is amplified to bring it back up to a watchable level, but here’s the clever part – it assesses how badly the signal has degraded and alters the amount of amplification it uses accordingly. This is to avoid over-amplifying pictures, which could make them look even worse.
Hi Focus also detects picture ‘ghosting’ caused by the signal
bouncing off buildings and other large obstructions, then cancels it out. The technology can also detect fast-moving objects and correct them so that they don’t look blurred. Again, this processing is adaptive, so it isn’t applied to objects moving more slowly.
