All TV screens used to be 4:3 (4 units across to 3 units in height), but now almost all new models, especially where there is digital television, are widescreen, 16:9. Pictures presented this way are believed to absorb more of our attention and have obvious advantages in certain productions, such as sport. In the change towards 16:9 some in-between ratios have been used for transmission, such as 14:9.

]]> Bayer Filter / Mask Array - A Bayer array is a pattern of red, green and blue non co-sited filters placed onto an imaging chip (CCD, CMOS) so that it can capture the separate red, blue and green primary colors of the image to make up a color digital image. As our eyes have more resolution for green light than red or blue, there are twice as many green cells as there are red and blue. Some redundancy of the green pixels produces an image which is less noisy and has finer detail than would be achieved if there were and equal number of red, green and blue cells.

The R, G and B pixels generated by the Bayer filter need to be ‘unmasked’ using a complex algorithm to produce white.

Traditionally professional TV cameras have used three image sensors, one to pick up each primary color. This arrangement demands that the three are finely registered together and involves a considerably more bulky construction and cost than the still digital cameras and consumer camcorders that use a single chip sensor with a Bayer, or other similar filter. However most new high-end professional cameras now have just one sensor.

It is fairly easily fooled by typical errors in data transmission systems so that, for most applications, a more sophisticated system is preferred.
