Is 720p vs 1080i worth being concerned about? Yes and no. If you’re a buyer looking for a new TV, you may happily ignore the 720p vs 1080i debate because each TV which is described as HDTV or HDTV Ready is required to aid both formats.

NOTE: You ought to be conscious altho that a large total of TVs which aid 1080i have less than 1080 lines and so scale the 1080 signal down. That’s not a big issue as even scaled down 1080i is far in front of a regular NTSC signal. It is worth bearing in mind that more costly HDTVs tend to have better scalers than for less ones, and this may be an issue.

However, for broadcasters it’s a live issue. Should they broadcast 1080 lines of interlaced video or 720 lines of progressive scan? They could just broadcast two signals, one in each format, but that would use up a big chunk of bandwidth and be hugely highpriced for very little gain.

To answer the question, it’s important to understand the divergence amongst 720p vs 1080i. A 720p signal is made up of 720 horizontal lines. Each frame is displayed in it is entirety on-screen for 1/30th of a second. This is recognise as progressive scan (hence the ‘p’)The quality is like watching 30 photographic images a second on TV. A 1080i signal comprises 1080 horizontal lines but all the lines are not displayed on-screen simultaneously. Instead, they are interlaced (hence the ‘i’), ie each other lines is displayed for 1/60th of a second and then the substitute lines are displayed for 1/60th of a second. So, the frame rate is still 30 frames per second, but each frame is split into two fields, which your brain then puts together subconsciously.

Most of the time interlacing works fine, but for fast moving images, such as sports like baseball and hockey it may cause difficulties which manifest themselves as a ‘stepping’ effect on-screen. Progressive scan signals don’t have this problem and so are better suitable to sports.

ESPN puts it like this: ‘Progressive scan engineering formulates better images for the fast moving orientation of sports television. Simply put, with 104 mph fastballs in baseball and 120 mph shots on goal in hockey, the line-by-line basis of progressive scan technology better captures the inherent fast action of sports. For ESPN, progressive scan engineering makes perfective sense.’

Bottom line? For us, as buyers 720p vs 1080i is not a debate worth worrying about, so you may relax and focus on all the other criteria on your list when you buy your next HDTV.
