Definição do conceito
[POR] Blu-ray (BD) | Disco Blu-ray, também conhecido como BD (de Blu-ray Disc) é um formato de disco óptico com 12 cm de diâmetro e 1,2 mm de espessura (igual ao CD e ao DVD) para vídeo e áudio de alta definição e armazenamento de dados de alta densidade. É uma alternativa ao DVD e é capaz de armazenar filmes de até 1080p Full HD por até 4 horas em compressão com perda de dados. Requer uma TV Full HD de LCD, plasma ou LED para explorar todo seu potencial. | Sua capacidade varia de 25 GB (camada simples) a 50 GB (camada dupla) – gigabytes. O disco Blu-Ray faz uso de um laser de cor azul-violeta, cujo comprimento de onda é 405 nanômetros (nm), permitindo gravar mais informação num disco do mesmo tamanho usado por tecnologias anteriores (o DVD usa um laser de cor vermelha de 650 nanômetros). | Blu-ray obteve o seu nome a partir da cor azul do raio laser ("blue ray" em inglês significa "raio azul"). A letra "e" da palavra original "blue" foi eliminada porque em alguns países não se pode registrar uma palavra comum em forma de um nome comercial. Este raio azul mostra um comprimento de onda curta de 405 nm e conjuntamente com outras técnicas, permite armazenar substancialmente mais dados que um DVD ou um CD. A Blu-ray Disc Association (BDA) é responsável pelos padrões e o desenvolvimento do disco Blu-ray e foi criada pela Sony, Panasonic, Pioneer e Philips. | Em junho de 2011, o analista do The NPD Group, Russ Crupnick disse que "o mercado de vídeo em disco físico foi um pouco decepcionante." Em 2014 a Time listou o Blu-ray em "5 produtos tecnológicos que serão mortos em 5 anos". Em 2016 os DVDs e Blu-rays deixaram de ser o meio mais lucrativo para distribuição de vídeo nos Estados Unidos e em 2017 no Reino Unido, sendo sucedido pela mídia digital e streaming. | FONTE : Blu-ray. in: Wikpedia.

[SPA] Blu-ray (BD) | El "disco Blu-ray", conocido como Blu-ray o simplemente BD (en inglés: Blu-ray Disc), es un formato de disco óptico desarrollado por la Blu-ray Disc Association (BDA), empleado para vídeo de alta definición (HD), 3D y UltraHD y con mayor capacidad de almacenamiento de datos de alta densidad que la del DVD. Para la reproducción de contenido 4K, Blu-ray ha sido reemplazado por Blu-ray Ultra HD. | FUENTE : Disco Blu-ray. Disponible en : https://es.wikipedia.org/wiki/Disco_Blu-ray Acceso en: 23 nov. 2022
==================================
[ENG] Blu-ray (BD) | 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 in 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. | The polycarbonate disc is 120 millimetres (4.7 in) in diameter and 1.2 millimetres (0.047 in) thick, the same size as DVDs and CDs. Conventional or pre-BD-XL Blu-ray Discs contain 25 GB per layer, with dual-layer discs (50 GB) being the industry standard for feature-length video discs. Triple-layer discs (100 GB) and quadruple-layer discs (128 GB) are available for BD-XL re-writer drives. | High-definition (HD) video may be stored on Blu-ray Discs with up to 1920×1080 pixel resolution, at 24& 50/60 progressive or 50/60 interlaced frames per second. DVD-Video discs were limited to a maximum resolution of 480 (NTSC, 720×480 pixels) or 576 lines (CCIR 625/50, 720×576 pixels, commonly used with PAL). Besides these hardware specifications, Blu-ray is associated with a set of multimedia formats. | The BD format was developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. Sony unveiled the first Blu-ray Disc prototypes in October 2000, and the first prototype player was released in Japan in April 2003. Afterward, it continued to be developed until its official worldwide release on June 20, 2006, beginning the high-definition optical disc format war, where Blu-ray Disc competed with the HD DVD format. Toshiba, the main company supporting HD DVD, conceded in February 2008,[8] and later released its own Blu-ray Disc player in late 2009.[9] According to Media Research, high-definition software sales in the United States were slower in the first two years than DVD software sales. Blu-ray faces competition from video on demand (VOD) and the continued sale of DVDs. In January 2016, 44% of U.S. broadband households had a Blu-ray player. For playback of 4K content, the BDA introduced a variant of Blu-ray called Ultra HD Blu-ray. | Ultra HD Blu-ray : Ultra HD Blu-ray discs and players became available in the first quarter of 2016, having a storage capacity of up to 100 GB. | The Holographic Versatile Disc (HVD), described in the ECMA-377 standard, was in development by the Holography System Development (HSD) Forum using a green writing/reading laser (532 nm) and a red positioning/addressing laser (650 nm). It was to offer MPEG-2, MPEG-4 AVC (H.264), HEVC (H.265), and VC-1 encoding, supporting a maximum storage capacity of 6TB. No systems conforming to the Ecma International HVD standard have been released. The company responsible for HVD went bankrupt in 2010, making any releases unlikely. | SOURCE : Blu-ray. in: Wikipedia. Available at : https://en.wikipedia.org/wiki/Blu-ray Accessed : 23 nov. 2022
