If you don’t want to go to the cinema after work but prefer to relax at home, you should set up a home cinema. The devices for a home cinema are designed to play DVDs and Blu-Rays in true cinema quality. In other words, both sound and picture quality are much better and convincing than in a real cinema. The actors appear more authentic, the stories are more real, the music more spectacular. So for real film fanatics, a home cinema is definitely worth an investment!

DVD and Blu-ray Disc

Exceptional image quality

The question of the reason for the popularity of Blu-Ray discs can best be answered with the quality of the movies and videos on this storage medium. The DVD has a maximum resolution of 720 x 480 with 414,720 pixels, while the Blu-ray Disc offers an HD resolution of 1,920 x 1,080 with 2,073,600 pixels. This five times higher resolution is clearly visible in the image comparison.

Of course, users need an appropriate Blu-Ray Player. Another advantage is that Blu-Ray drives are downward compatible. This means that DVDs can be played with them in the same way as Blu-Ray discs, which is not the case with the DVD drive.

Higher sound quality

Not only in terms of picture quality is the BD ahead of the DVD by a few lengths: If you watch your movies on Blu-ray Disc, you also enjoy better sound. While the DVD only supports the audio codecs Linear PCM, Dolby Digital and DTS, BDs also feature the lossless audio codecs Dolby TrueHD and DTS HD as well as the multi-channel sound system Dolby Digital Plus.

Data volume

Blu-ray Disc

The qualitative advantages of the Blu-ray Disc are due to the storage space of the newer media. A DVD has 4.7 gigabytes of storage space as a single layer, while the Blu-ray Disc already has a proud 25 gigabytes in the single-layer version. Double-layer Blu-ray discs even offer 50 gigabytes compared to the 8.3 gigabytes of the corresponding DVD variant. This means that considerably more information can be stored on the blue discs.

In addition, the data is written much more densely onto the disc with shorter-wave laser light and a smaller laser dot. So-called BD-XLs, i.e. Blu-Ray discs in extra-large format, offer particularly large storage space. These are available in the three-layer version as triple-layer BD with 100 gigabytes of storage space and as quad-layer BD with 128 gigabytes of storage space.

Blu-Ray players and drives must be able to handle the high data volumes with a correspondingly high reading speed, which is why they can handle a data transfer rate three times as high as DVD drives: 35.96 megabytes per second compared to 11.08 megabytes per second for DVD drives.

Alternatives

Blu-ray player

If you don’t have a Blu-ray player but still own some of these storage media, there is a choice. Blu-Ray to DVD conversion allows you to convert the data to other formats. On PC or laptop, the Blu-ray disc file format can be converted to DVD format so that it is available in DVD format. Users can burn this format to a regular DVD and play it on a regular DVD player. However, the loss of quality is inevitable with this conversion.

Nonetheless, this is a great way to get data from Blu-ray discs to the storage medium of choice. The user’s own laptop or PC, Blu-Ray drive Blu-Ray player software blue disc is recommended.
