Definição do conceito
[POR] Betacam | Betacam é uma família de formatos de videoteipes profissionais de meia polegada (1/2") criada pela Sony em 1982. Todos os formatos utilizam o mesmo tipo de fita magnética, que é o que define a Betacam, com a mesma largura e forma de fita. Suas distintas variantes o tornam um sistema altamente compatível e com uma ampla evolução. Os videoteipes Betacam têm dois tamanhos diferentes: "S" (do inglês small, pequeno) e "L" (do inglês large, grande). Porém, as câmeras Betacam suportam apenas o tamanho "S", enquanto que os aparelhos de videocassete suportam ambos os formatos. Os cassetes e caixas possuem cores diferentes, dependendo do formato específico em questão. Betacam incorpora uma chave mecânica que permite ao aparelho de videocassete identificar a que sistema pertence a fita inserida nele. | Betacam (1982-1990) : Introduzido em 1982 pela Sony, com uma linha de câmeras e um leitor de fitas, alcançou um rápido sucesso devido à sua qualidade de imagem e também com o lançamento das primeiras camcorders, câmeras que uniam as funções de captar e registrar as imagens. As fitas Betacam tinham sua estrutura semelhante às fitas Betamax. Tanto que um fita virgem de um formato podia ser utilizado para gravar no outro formato. ... | FONTE : Betacam. in: Wikipedia.

[SPA] Betacam | Betacam es una familia de formatos de videocintas profesionales de 12,7 mm creada por Sony en 1982. | Todos los formatos usan el mismo tipo de cinta magnética, que es lo que define a Betacam, con idéntico ancho de cinta y forma de enhebrado. Sus distintas variantes lo convierten en un sistema altamente compatible y con una amplia evolución. Los casetes tienen dos tamaños distintos: S (del inglés small, pequeño) y L (de large, grande) . Las cámaras Betacam sólo admiten el tamaño S, mientras que los magnetoscopios soportan S y L. Los casetes y los estuches tienen colores distintos dependiendo del formato específico del que se trate. Betacam incorpora una clave mecánica que permite al magnetoscopio identificar a qué sistema pertenece la cinta insertada en él. | ... El primer formato ´Betacam´ fue lanzado en 1982. Es un sistema analógico de vídeo por componentes, que almacena la luminancia (Y) en una pista y las señales de crominancia (R-Y, B-Y) en otra distinta. La separación de las señales proporciona una calidad suficiente para un entorno de teledifusión con 300 líneas verticales de resolución. | El Betacam original utiliza cintas magnéticas, que son exactamente las mismas que su versión doméstica, el Betamax, creado también por Sony en 1975. Las cintas vírgenes Betacam se pueden usar en magnetoscopios Betamax y viceversa. La diferencia entre ambos formatos consiste en que Betamax graba una señal de vídeo compuesto (al igual que otros formatos como VHS, U-Matic y el formato C de 1 pulgada), mientras que Betacam usa una señal por componentes y una mayor velocidad de paso de cinta, lo que proporciona mejor calidad de audio y vídeo. Una cinta L-750 permite 3 horas de grabación en Betamax y sólo 30 minutos de grabación en Betacam, pero con una calidad muy superior. }| FUENTE : Betacam. in: Wikipedia.

[ENG] Betacam | Betacam : N.B.:This article is about the professional Betacam format. Not to be confused with the related but incompatible Betamax format, nor the consumer-oriented Betamovie camcorder line. | Betacam is a family of half-inch professional videocassette products developed by Sony in 1982. In colloquial use, "Betacam" singly is often used to refer to a Betacam camcorder, a Betacam tape, a Betacam video recorder or the format itself. | All Betacam variants from (plain) analog recording Betacam to Betacam SP and digital recording Digital Betacam (and additionally, HDCAM and HDCAM SR), use the same shape videocassettes, meaning vaults and other storage facilities do not have to be changed when upgrading to a new format. The cassettes are available in two sizes: S (for Short) and L (for Long). The Betacam camcorder can only load S magnetic tapes, while television studio sized video tape recorders (VTR) designed for video editing can play both S and L tapes. | The cassette shell and case for each Betacam cassette is colored differently depending on the format, allowing for easy visual identification. There is also a mechanical key that allows a video tape recorder to identify which format has been inserted. | The format supplanted the three-quarter-inch U-Matic format, which Sony had introduced in 1971. In addition to improvements in video quality, the Betacam configuration of an integrated professional video camera/recorder led to its rapid adoption by electronic news gathering (ENG) organizations. | DigiBeta, the common name for Digital Betacam, went on to become the single most successful professional broadcast digital recording video tape format in history, but now although Betacam remains popular in the field and for archiving, new tapeless digital products have led to a phasing out of Betacam products in television studio environments since 2006. | SOURCE : Betacam. in: Wikipedia : Available at : https://en.wikipedia.org/wiki/Betacam Accessed at : 18 n ov. 2022

[ENG] Betacam | Betacam (1982 – 1990s) | Betacam was a ½-inch analogue video cassette format for broadcast use, first introduced by Sony in 1982. As the name implies, the format was a professional version of Betamax and was rapidly adopted for electronic news gathering, replacing the Sony U-Matic ¾-inch format. Whereas Betamax lost out to VHS in consumer video, Betacam and its successors were very successful in broadcasting. | Betacam was a component video format using ferric-oxide tape and offering broadcast-quality 300-line horizontal resolution. The smaller version came in a shell the same size as Sony’s Betamax format and whilst it was possible for the two formats to use each other’s tapes, this practice was discouraged. Betacam also introduced a new large size shell, for use in video editing machines, and this offered longer recording times.| In 1986, Betcam SP was launched, and although still an analogue format, it offered increased resolution by using metal-formulated tape. | Dimensions (S-size): 15.6 cm × 9.6 cm × 2.5 cm | Dimensions (L-size): 25.4 cm × 14.5 cm × 2.5 cm | SOURCE : MUSEUM OF OBSOLETE MEDIA.
