Definição do conceito
[POR] HDCAM SR | HDCam SR (2003-2016) : O HDCam SR foi apresentado em 2003 como um formato superior ao HDCam, por isso a existência da sigla "SR" (de Superior Resolution, resolução superior). O formato, além de gravar em uma compressão superior de imagem (sinal RGB a 10-bits por 4:2:2 ou 4:4:4), também grava em uma taxa de compressão maior (440 Mbits/s ou 880 Mbit/s, dependendo do equipamento) do que a HDCam. | FONTE : Betacam. in: Wikipedia.

[SPA] HDCAM SR | HDCAM SR es una variación del anterior creada en 2003. Utiliza una cinta con alta densidad de partículas que permite grabar una señal RGB con muestreo 4:4:4 a un bitrate de 440 Mb/s. Esto permite capturar una resolución máxima de 1920x1080 y hasta 12 canales de audio. HDCAM SR usa una compresión MPEG-4 Studio Profile de alta calidad que no utiliza grupos de imágenes (GOP), por lo que no da los típicos problemas de MPEG a la hora de editar, y usa compresión intracuadro en progresivo y compresión intracampo en entrelazado. Algunos magnetoscopios HDCAM SR tienen un segundo modo que alcanza los 880 Mb/s, lo que permite un único flujo de vídeo con menor compresión o dos flujos simultáneamente. El modo 440 Mb/s es SQ y el modo 880 Mb/s, HQ. HDCAM SR sigue permitiendo un 4:2:2 por componentes. | La duración de cintas es la misma que el formato Betacam Digital: 40 para la talla S y 124 para el tamaño L. En su versión de 24 fps, alcanza los 50 y 155 minutos, respectivamente. | HDCAM SR usa cartuchos negros con pestaña azul. | Dentro de los formatos HDCAM y HDCAM SR, Sony cuenta con la gama CineAlta, con equipos especialmente diseñados para su uso en rodajes de cine. | FUENTE : Betacam. in: Wikipedia.

[ENG] HDCAM SR | HDCAM SR was introduced in 2003 and standardised in SMPTE 409M-2005. It uses a higher particle density tape and is capable of recording in 10 bits 4:2:2 or 4:4:4 RGB with a video bit rate of 440 Mbit/s, and a total data rate of approximately 600 Mbit/s. The increased bit rate (over HDCAM) allows HDCAM SR to capture much more of the full bandwidth of the HD-SDI signal (1920×1080). Some HDCAM SR VTRs can also use a 2× mode with an even higher video bit rate of 880 Mbit/s, allowing for a single 4:4:4 stream at a lower compression or two 4:2:2 video streams simultaneously. HDCAM SR uses MPEG-4 Part 2 Simple Studio Profile for compression, and expands the number of audio channels up to 12 at 48 kHz/24-bit. | There are 12 channels of audio recorded uncompressed at 24 bit 48 kHz sampling. Each channel is capable of recording AES3 non-audio data. | HDCAM SR was used commonly for HDTV television production. In the mid-2000s, many prime-time network television shows used HDCAM SR as a master recording medium, but it is no longer in widespread use. | Some HDCAM VTRs play back older Betacam variants, for example the Sony SRW-5500 HDCAM SR recorder plays back and records HDCAM and HDCAM SR tapes, and with optional hardware also plays and upconverts Digital Betacam tapes to HD format. Tape lengths are the same as for Digital Betacam, up to 40 minutes for S and 124 minutes for L tapes. In 24p mode the runtime increases to 50 and 155 minutes, respectively. | HDCAM tapes are black with an orange lid, and HDCAM SR tapes black with a cyan lid. | 440 Mbit/s mode is known as SQ, and 880 Mbit/s mode is known as HQ. | SOURCE : HDCAM. in: Wikipedia.

[ENG] HDCAM SR | HDCAM SR (2003 – 2016) | HDCAM SR (Superior Resolution) was a professional high-definition digital video cassette format, introduced by Sony in 2003 as a higher quality variant of its existing HDCAM system. | Like other Betacam-related formats, HDCAM SR cassettes were available in large and small sizes, and had the same tape lengths as Digital Betacam (up to 40 minutes for S and 124 minutes for L tapes). | It used higher particle density tape allowing an increased bit rate (a choice or 440 or 880 Mbps). Like HDCAM, it was commonly used in high-definition television production. | Sony HDCAM SR tapes were black with a cyan lid and contained a 1K memory chip to store metadata about the tape. | In 2016, Sony announced that it was ceasing production of its remaining ½-inch video tape recorders and players, including those for the HDCAM SR format. | 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.

[ENG] HDCAM SR | HDCAM / HDCAM SR | Description : HDCAM was introduced in 1997 as the high-definition version of Digital Betacam. Like others in the Betacam family, HDCAM came in both small and large cassette profiles. Small HDCAM cassettes bear resemblance to the original Betamax casing. Panasonic´s DVCPro HD was the HDCAM´s competitor of this early era of high-def video | HDCAM SR was introduced in 2003 with increased bit rate capacity and higher particle density tape composition. Since the late 2000s, HDCAM SR has been used for HDTV television production. HDCAM tapes are black with an orange tape guard; HDCAM SR tapes are black with cyan. | SOURCE : PSAP - Preservation Self-Assessment Program. Collection. University of Illinois at Urbana-Champaign.
