1080p (where ‘P’ stands for progressive scan) is the highest resolution format of display for TVs. He often said that 1080p does not provide benefits to anything, except for very large screens and are usually not used because the media, using it is not always available. It is simply not true!
He often said that the format of 1080p, has a higher resolution than the format of 1080i. This can lead a better quality image, but they are both the same resolution of 1920 x 1080. It simply means that both the format of 1920 by 1080 pixels of horizontal lines.
The difference between interlaced and progressive scan techniques can be shown in this way.
With true 1080i HD TV images on the screen are selected and updated 60 times per second (60 Hz). Not all the 1080 lines but they are selected or updated each time. Interlaced only alternate rows updated for each instance and so for all rows to be refreshed by two cycles of the sample must pass.
This is the flip side is interlaced when the image is not moving to alternative lines correspond to normal, but the movement is currently the line does not match together, and the result is called jitter.
The fundamental difference with 1080p or a progressive format is that all images selected and is updated every time, which is 60 times per second. Why, then, with a 1080p TV can improve the input format of 1080i? What happens to the signal of 1080i 1080p television is that it is deinterlaced.
This method involves the processing of image areas that are moving and their interpolation and areas that do not move and then combined together. As a result, the output of photo is one area where traffic is only the areas where there is any loss in detail.
