A three-dimensional (3D) Blu-ray™ player is an electronic device that can play Blu-ray discs™ that are specially made to allow for a 3D signal to be sent by them. These devices are typically used with a High-Definition Television (HDTV) that is also designed to properly display 3D images. When a 3D movie is played on this type of setup, then viewers can wear special glasses that allow them to see the images on the HDTV as though projected into the room. A 3D Blu-ray™ player also typically includes other features, such as the ability to play standard movies and inclusion of streaming media services.
The primary function of a 3D Blu-ray™ player that sets it apart from many similar devices is the ability to play 3D movies. Blu-rays™ are a type of digital data storage disc, somewhat similar to other formats such as Compact Discs (CDs) and Digital Versatile Discs (DVDs), but with much greater storage capacity. This improved storage and advances in entertainment technology have made it possible for 3D Blu-ray discs™ to be made that contain data for 3D picture playback.
Use of a 3D Blu-ray™ player largely relies upon a 3D HDTV, however, as the signal sent by the player needs to be received and displayed properly. An HDTV has higher quality image resolution than traditional televisions, and 3D HDTVs are able to play signals for 3D television viewing. This requires the use of special glasses that allow the wearer to view the image in 3D. Different films and shows can use this technology in various ways, though it typically appears as though some or all of an image is coming out from the screen toward the viewer.
While a 3D Blu-ray™ player is intended for use with 3D Blu-ray discs™, it can also play other types of media storage. CDs and DVDs can usually play through these devices, and many of them can improve the picture quality of a DVD to be closer to the resolution and definition of a newer media. A 3D Blu-ray™ player can also be used to view movies on standard Blu-rays™.
There are also a number of additional features that are sometimes included with a 3D Blu-ray™ player, such as the ability to receive and play streaming media. These devices can be used with various services and connected to an Internet signal to then relay audio or video through the entertainment system to which they are connected. This allows a viewer to watch movies that are playing from a source over the Internet, or to listen to online music broadcasting stations.
