The answer depends on what you’re after. Both disc players differ in many ways. You have to determine from the following factors that which features are essential for you.
Two factors are involved in evaluating the Video Quality of both Blu-ray Discs and digital discs.
DVDs are a 2D version of movies, which were produced mainly to entertain people at home. Then, movies material is stored on several DVDs, so what we can see is one movie. But Blu-ray Discs record many frames simultaneously to see many different scenes, which means more than one movie can be displayed on each disc. Playing Blu-ray Discs on a video player will show us this complex image with complex colors and sharp edges because it provides information about each frame.
The next factor is the compression of digital video data. As digital discs store videos as data, we can not get such complex images as Blu-ray discs. It depends on the type of compression chosen by the production team of a specific movie.
In general, Blu-ray Discs provide more information for each frame and better video data compression than DVDs and digital disc players. So, we will get more and more precise pictures and fewer noise (digital artifacts) with Blu-ray discs than we do with DVDs or digital disc players.
Audio quality is another factor that is evaluated in comparing the audio quality of Blu-ray Discs and digital disc players. There are two ways to store or record sound on DVDs or play them back on a DVD player. The first way is stereo recording, which records the original sound as separate channels at different times. The second method fixes to a particular time or time code of various parts of the soundtrack into which these parts are then stored separately.
As Blu-ray Discs store movies as data, we can not get such a rich sound as we will get with Blu-ray discs. However, this is not the case for digital discs. So, they can provide us better quality sound than Blu-ray discs. On average, just like video quality, most music recorded on DVD uses Dolby Digital 5.1 encoding technology to encode the movie’s soundtrack to be viewed at home.
Blu-ray Discs are more versatile than digital disc players because of their capability to play music and video formats other than CD/DVD originals (including content encoded in HDV and AVCHD formats).
Digital discs Players are becoming more popular among video lovers because they can play videos from all digital disc formats and are very easy to use than Blu-ray Disc Players and Blu-ray Discs. DVD players are top-rated, and most people have them. In most restaurants, you can watch a DVD movie with your family or friends. In most homes, DVDs are very popular because most people have DVD players.
According to most research studies, most Blu-ray Discs are more expensive than digital discs players. The reason is that producing Blu-ray disc products is very costly than making products specifically for DVDs because of its complexity and proper usage of advanced technology. digital disc players are more prevalent among people; they are available in all types of markets, with the price range varies according to model and features. Since both Blu-ray Discs and digital disc players are available in the market, the prices of both products vary according to quality.
Most of the movies recorded on DVDs look very flat and without any sharpness. The contrast ratio should reach 10000:1, but it rarely reaches 30000:1. So, Blu-ray Discs provide us an analog experience than digital disc players or DVDs because of their high contrast ratio, which can provide us clearly, sharp pictures with high sound levels.
Emulation is a software technology used to play the contents of one format on another format. For example, suppose you have a Blu-ray player emulation for DVD movies or vice versa. In that case, the movie will appear to be recorded using the same kind of disc as recorded initially without losing quality. Many manufacturers are now offering Blu-ray Disc players that emulate old DVDs. It means that the native format that they are made for can run on them just as it can run on a Blu-ray Disc player.
In some cases, you can have both Blu-ray discs and DVD players on one home entertainment system, depending on the content. In this case, it is possible to use a Blu-ray Disc player as a video recorder or as a player for videos on DVDs. Some DVD players also give the option of being able to play games. If you have a DVD-Video disc with some games on it, it will play on most DVD players without losing quality compared to what was initially recorded.
Sometimes it is nice to watch your favorite movie again and again without buying new discs each time. Once burned onto a disc, a Blu-ray Disc cannot be removed without affecting the quality. It means that you will always need to buy Blu-ray Discs when you want to watch your favorite movie again and again. Digital disc players and DVDs can be replayed many times thanks to their low manufacturing cost and ease of use. They also have much lower prices than Blu-ray Discs, so buying new discs is less of an issue than with Blu-ray Discs.
Many Blu-ray players have built-in internet access, which means that you can use the player to read news, view movies and even listen to audiobooks. It also makes it much easier to look up information related to your favorite movie or game. If you own a Blu-ray Disc player that does not have this capability, you will need to connect your player directly to your home computer. It may require purchasing an additional cable or adapter. Digital disc players do not offer the same capabilities as Blu-ray Discs because they are designed mainly to play video content rather than digital multimedia entertainment.
Thus, you are the one to make the d3ecision which one you should buy, as per your needs and preferences.
