Technology is getting more and more advanced every day. In this world of competition when it comes to televisions, cameras, music, and video games, people are always looking to have the newest and latest thing out. One of the major topics in the entertainment industry is which is better, DVD or Blu-Ray' Despite the similarities, the Blu-ray disc’s advantages greatly out weigh those of Digital Video Disc.
When it comes to media quality, DVDs have less to offer in comparison to Blu-rays. A DVD presents the consumer with a restricted 480p resolution. 480p, which is 480 megapixels, is slightly better than the image resolution available on basic television. The images on the screen may not be very clear and can sometimes look blurry. The DVD menu also lacks accessibility for special features making it hard to navigate through screens. The audio quality comes in two formats Dolby Digital and DTS. Dolby digital and DTS (Digital Theater System) are two different features that allow the DVD to project audio in surround sound.
Blu-rays have more to propose to a buyer. Blu-ray discs offer a better image quality. The Blu-ray image resolution is at 1080p, which is currently the highest quality available. Blu-rays are so clear and detailed that sometimes people feel like they are in the movie theater. The audio features on a Blu-ray are Dolby True HD, and DTS HD Master. Just like the DVD, these are two audio formats that allow the Blu-ray to project audio in surround sound but these formats give a sound that is very similar to the master studio sound. One thing very neat thing about the Blu-rays is the special feature menu. Blu-rays have a great improvement that allows a person to access the main menu while still watching the movie as opposed to a regular DVD, which forces you to exit the movie just to access the main menu.
The availability of DVDs surpasses those of Blu-rays. There are over ninety thousand available titles to choose from. You can find anything from shows and movies to documentaries and music videos. The cost for DVDs can range from retail price at twelve dollars to five-dollar sale bins at a local Wal-Mart, or the used section at a blockbuster video rental store. Also DVD players are fairly cheap. You can buy a DVD player nowadays for one hundred dollars or less. You can even find some at garage sales or flea markets. DVDs are also compatible with almost all gaming system consoles.
The downside for the Blu-ray is the lack of available titles compared to DVDs. There are roughly a thousand titles, but the selection will continue to grow within the years. A Blu-ray price can range from twenty-three dollars to twenty-eight dollars. Blu-ray players can be a bit costly. Blu-ray players are on sale anywhere from one hundred and seventy dollars to four hundred dollars. The Blu-ray is only compatible with one gaming system, which is the PlayStation three; it is the only game system advanced enough to play them.
Many people can argue that DVDs and Blu-rays are the same thing. Yes, DVDs maybe cheap and available everywhere, but when comparing the advantages, the Blu-ray discs exceed the DVDs in almost every category. For a few more dollars, one can have a close to a movie theater experience right at home. I believe Blu-rays will continue to expand and grow and will one day become what the DVD is today.
