720p Vs 1080i HDTV

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

NOTE: You should be aware though that lots of TVs which support 1080i have fewer than 1080 lines and so scale the 1080 signal down. That's not a huge issue as even scaled down 1080i is far ahead of a regular NTSC signal. It is worth bearing in mind that more expensive HDTVs tend to have better scalers than cheaper 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 huge chunk of bandwidth and be hugely expensive for very little gain.

720p Vs 1080i HDTV

To answer the question, it's important to understand the difference between 720p vs 1080i. A 720p signal is made up of 720 horizontal lines. Each frame is displayed in its entirety on-screen for 1/30th of a second. This is know 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 every other lines is displayed for 1/60th of a second and then the alternate 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 can cause problems which manifest themselves as a 'stepping' effect on-screen. Progressive scan signals don't have this problem and so are better suited to sports.

ESPN puts it like this: 'Progressive scan technology produces 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 technology makes perfect sense.'

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

Black Friday TV Sales Predictions From WalMart - Samsung TVs Possible at Discounted Prices

Before going out and paying full price for any TV as a Christmas gift it is always smart to look and see what HD TVs will be on sale during the Black Friday deals. One of the most popular items during this huge sales event always happens to be a new TV. There are many retailers that offer amazing discounts and one of these retailers happens to be the largest retailer in the world - WalMart.

Before making any predictions when it comes to TV sales in 2010 it would be very smart to look at the Black Friday deals that were available in 2009. The follow is a listing of the TV discounts that took place on the Friday after Thanksgiving at WalMart last year:

Black Friday TV Sales Predictions From WalMart - Samsung TVs Possible at Discounted Prices

When looking at these sales it seems to be the case that WalMart has a long term relationship with Sony and Samsung. With this being the case we can predict that we will see sales and deals from these types of TVs in 2010. The price of the actually TVs remains a debate. One thing is for certain, there will be some very good deals that can help Americans save quite a bit of money during the Thanksgiving Friday sales.

With the overall economy greatly struggling there is very little argument to be made that Americans will be looking to save as much money as possible during the shopping season. Some reports have stated that Americans are looking to cut back greatly this year. Will customers cut back on TV purchases? There is only one way to find out and that is to wait and see how WalMart and the other retailers do when it comes to sales.
