Definição do conceito
[ENG] Betacam is a family of 12.7 mm professional videotape formats created by Sony in 1982. | Betacam / Betacam SP : The first format ´ Betacam´ was released in 1982. It is a system analog of component video , which stores the luminance (Y) on a track and signals chrominance (RY, BY) in another. | ... | The original Betacam uses magnetic tapes, which are exactly the same as its home version, the Betamax , also created by Sony in 1975. Blank Betacam tapes can be used in Betamax VTRs and vice versa. | ... | The Betacam SP system ( Betacam Superior performance , Betacam of superior performance) was created in 1986, and improved its resolution to 340 vertical lines and added two AFM audio tracks, in addition to the 2 longitudinal ones already existing. Betacam SP became the video standard for broadcasters and high-end production until the advent of digital formats in the mid-1990s. | Digital Betacam | The Betacam Digital (also known as Digi Beta and DBC ) was launched in 1993. | ... | Betacam Digital records using a component video signal compressed with the DCT algorithm (the compression ratio is variable, usually around 2:1). Its color depth is 10 bits and its sampling pattern is 4: 2: 2 in PAL (720x576) and NTSC (720x486), resulting in a 90 Mb/s bitrate. In terms of sound, it provides 4 channels of PCM audio at 48 kHz and 20 bits. Includes two longitudinal tracks for track control and time code. | ... | In terms of sound, it provides 4 channels of PCM audio at 48 kHz and 20 bits. Includes two longitudinal tracks for track control and time code. | Audio channels 4 PCM channels | Audio sampling 48 kHz / 20 bits || Betacam SX | Betacam SX is a digital format created in 1996, with the idea of ??being a cheaper alternative to Betacam Digital, especially for ENG work. Compresses the component signal using MPEG-2 4: 2: 2 Profile @ ML (MPEG-2 4: 2: 2P @ ML), with 4 channels of PCM audio at 48 kHz and 16 bits. Betacam SX is compatible with Betacam SP tapes. Size S holds up to 64 minutes and size L holds up to 194. | Audio channels 4 PCM channels | Audio sampling 48 kHz / 16 bits | SOURCE : BETACAM. in: Second Wiki. https://second.wiki/wiki/betacam Accessed : 10 aug. 2022.
