The Blu-ray Disc (BD), often known simply as Blu-ray, is a digital optical disc data storage format. It was invented and developed in 2005 and released on June 20, 2006 worldwide. It is designed to supersede the DVD format, and capable of storing several hours of high-definition video (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X. The name "Blu-ray" refers to the blue laser (which is actually a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.

As with the implementation of region codes for DVDs, Blu-ray Disc players sold in a specific geographical region are designed to play only discs authorized by the content provider for that region. This is intended to permit content providers (motion picture studios, television production company etc.) to enact regional price discrimination and/or exclusive content licensing. According to the Blu-ray Disc Association, all Blu-ray Disc players and Blu-ray Disc-equipped computer systems are required to enforce regional coding. However, content providers need not use region playback codes.[194] Some current estimates suggest 70% of available movie Blu-ray Discs from the major studios are region-free and can therefore be played on any Blu-ray Disc player in any region.[195]
The Blu-ray Disc Association (BDA) created a task force made up of executives from the film industry and the consumer electronics and IT sectors to help define standards for putting 3D film and 3D television content on a Blu-ray Disc.[230] On December 17, 2009, the BDA officially announced 3D specs for Blu-ray Disc, allowing backward compatibility with current 2D Blu-ray players,[231] though compatibility is limited by the fact that the longer 3D discs are triple-layer, which normal (2D only) players cannot read. The BDA has said, "The Blu-ray 3D specification calls for encoding 3D video using the "Stereo High" profile defined by Multiview Video Coding (MVC), an extension to the ITU-T H.264 Advanced Video Coding (AVC) codec currently implemented by all Blu-ray Disc players. MPEG4-MVC compresses both left and right eye views with a typical 50% overhead compared to equivalent 2D content, and can provide full 1080p resolution backward compatibility with current 2D Blu-ray Disc players."[232] This means the MVC (3D) stream is backward compatible with H.264/AVC (2D) stream, allowing older 2D devices and software to decode stereoscopic video streams, ignoring additional information for the second view. However, some 3D discs have a user limitation set preventing the disc from being viewed in 2D (though a 2D disc is often included in the packaging).[citation needed]

The projector also comes with an Android TV dongle and a capable Netflix app. And its three-LCD-chip design eliminates any possibly of seeing the red, green, and blue flashes, known as rainbow artifacts, that some people see more easily than others. The price is a little high for the 720p resolution, but most 720p and 1080p projectors that offer both portability and 2,000 lumens use lamps that, unlike lasers, have to be replaced over the life of the projector, raising the total cost of ownership.
Most mini projectors are less expensive than any room-to-room portable, and the Solar Portable is our top pick in the category. Even better, along with a low price, it fits a lot of features into a small package, including native 1080p resolution, built-in Android TV 9 for streaming over a Wi-Fi connection and for screen mirroring, and a built-in rechargeable battery that can outlast most full-length movies. Anker rates the Solar Portable at 400 ANSI lumens, which isn't as bright as most room-to-room portables, but we found it bright enough to fill a 90-inch screen in the dark and be watchable on an 80-inch screen in moderate ambient light.
The Solar Portable will appeal to those who are either on a tight budget or want a 1080p projector that's more portable than room-to-room models. Its only important limitation for watching movies is its audio. In our tests, the dual 3-watt speakers delivered distorted sound at top volume and offered no better than serviceable quality at mid volume. But if you already have an external audio system or powered speakers you can use with it outdoors, you can still get the benefit of the budget price. If not, the cost of the Solar Portable plus speakers may not save you money over a projector with a more robust onboard sound system. However, if you also need a fully portable projector for, say, business presentations on the go, it can save you the cost of buying separate projectors for home and work.
The EpiqVision Mini EF12 is built around a 1,000-lumen laser-phosphor light source and a set of three 1080p LCD chips. The three-chip design is an absolute guarantee that it can't exhibit the red-green-blue flashes called rainbow artifacts that some people see easily and find unacceptable. The 1,000 lumens makes it bright enough for an 80-inch image even in backyards with unusually bright ambient light, and suitable for larger images in darker yards. Other key features include integrated Android TV and a 4.7-pound weight, which is unusually light for a laser projector. The Android TV doesn't support a reliable Netflix app at this writing, but Epson says one may be added.
Anyone who sees rainbow artifacts easily and finds them annoying should consider the EF12 a prime candidate for a 1080p outdoor projector. They may even consider it preferable to currently available 4K projectors, since no 4K models available yet are both suitable for outdoor use and also offer a guaranteed rainbow-free technology. Even if rainbow artifacts don't bother you, it's worth considering. In fact, it's our top pick among 1080p room-to-room portables, delivering good image quality and a brighter image for picture modes that you'll actually want to use, versus most of the like-priced competition. 2ff7e9595c
