All use the same shape cassettes, meaning vaults and other storage facilities do not have to be changed when upgrading to a new format. The cassettes come in two sizes, S and L. Betacam cameras can only load the S tape, while VCRs can play both S and L tapes. The cassette shell and case for each Betacam cassette is colored differently depending on the format, this allows for easy visual identification. There is also a mechanical key that allows a video tape recorder to tell which format has been inserted. A professional video camera (often called a television camera even though the use has spread) is a high-end device for recording electronic moving images (as opposed to a movie camera, that records the images on film). ... The video cassette recorder (or VCR, less popularly video tape recorder) is a type of video tape recorder that uses removable cassettes containing magnetic tape to record audio and video from a television broadcast so it can be played back later. ...

Betacam / Betacam SP

The original Betacam format launched in 1982. It is an analog component format, storing the luminance (Y) in one track and the chrominance (R-Y, B-Y) on another. This splitting of channels provides a crisp, true broadcast quality product with 300 lines of horizontal resolution. 1982 is a number and represents a common year starting on Friday of the Gregorian calendar Events January-February January 6 - William Bonin is convicted of being the freeway killer.

In 1986 Betacam SP was developed, which increased horizontal resolution to 340 lines. Beta SP (for "Superior Performance") became the industry standard for most TV stations and high-end production houses until the late 1990s. The recording time is the same as for Betacam, 30 and 90 minutes for S and L, respectively. 1986 is a common year starting on Wednesday of the Gregorian calendar. ...

Sonys D1 format was the first major professional digital video format, introduced in 1987. ...


The Digital Betacam format records a DCT-compressed component video signal at 10-bit YUV 4:2:2 sampling in PAL (720x576) or NTSC (720x480) resolutions at a bitrate of 90 Mbit/s plus 4 channels of uncompressed 48KHz PCM-encoded audio. A 5th audio track is available for cueing, and a linear timecode track is also used on the tape. The discrete cosine transform (DCT) is a Fourier-related transform similar to the discrete Fourier transform (DFT), but using only real numbers. ... Component video is a type of video information that is transmitted or stored as two or more separate signals (as opposed to composite video, such as NTSC or PAL, which is a single signal). ... YUV 4:2:2 is a specific encoding for digital representation of the YUV color space. ... For other meanings of PAL see PAL (disambiguation). ... Pulse-code modulation (PCM) is a modulation technique. ... Timecode is also the title of a 2000 film directed by Mike Figgis which was shot in one continuous take. ...


Some Digital Betacam equipment can also read Betacam and Betacam SP tapes. Along with the identical cassette size, this meant for easy upgrading.


Digital Betacam is considered to be the gold standard of formats for standard-definition digital video, is capable of outperforming cheaper digital formats such as DVCAM and DVCPRO, and associated equipment is comparatively expensive. Panasonic offers the DVCPRO50 competing format, which has similar technical abilities. DVCAM is Sonys professional implementation of the DV standard, using 15 micrometre tracks instead of DVs 10 micrometre tracks. ... DVCPRO, DVCPRO 50, and DVCPRO HD refer to digital videotape formats using the DV codec, and devised by Panasonic. ... A MiniDV tape DV (disambiguation). ...


Another key element which aided adoption was Sony's implementation of the Serial Digital Interface (SDI) coaxial digital connection on Digital Betacam decks. Facilities could begin using digital signals on their existing coaxial wiring without having to commit to an expensive re-installation. Serial Digital Interface (SDI), standardized in ITU-R 656, is a digitized video format used for broadcast grade video. ...


Digital Betacam tapes are a muted blue.


Betacam SX

Betacam SX S tape

Betacam SX is a digital version of Betacam SP introduced in 1996, positioned as a cheaper alternative to Digital Betacam. It stores video using MPEG 4:2:2 Profile@ML compression, along with 4 channels of 48 KHz 16 bit PCM audio. All Betacam SX equipment is compatible with Betacam SP tapes. S tapes have a recording time up to 62 minutes, and L tapes up to 194 minutes. Download high resolution version (1783x1431, 280 KB) Wikipedia does not have an article with this exact name. ...

MPEG IMX

MPEG IMX is a 2001 development of the Digital Betacam format. It uses the MPEG compression system, but at a higher bitrate than Betacam SX. The IMX format allows for a CCIR 601 compliant video signal, with 8 channels of audio as well as cue and timecode tracks. 2001 is a common year starting on Monday of the Gregorian calendar. ... The Moving Picture Experts Group (MPEG) is a small group charged with the development of video and audio encoding standards. ... CCIR 601 is the old name of a standard published by the CCIR (now ITU-R) for encoding interlaced analogue video signals in digital form. ... Timecode is also the title of a 2000 film directed by Mike Figgis which was shot in one continuous take. ...


With its new IMX VTRs, Sony introduced some new technologies including SDTI and e-VTR. SDTI allows for audio, video, timecode, and remote control functions to be transported by a single coaxial cable, while e-VTR technology extends this by allowing the same data to be transported over IP by way of an ethernet interface on the VTR itself. The Internet Protocol (IP) is a data-oriented protocol used by source and destination hosts for communicating data across a packet-switched internetwork. ...


IMX VTRs such as the MSW-2100M are capable of playing back Digital Betacam cassettes as well as analog Betacam SP cassettes, but can only record to their native IMX cassettes. S tapes are available with up to 60 minutes capacity, and L tapes hold up to 184 minutes.


MPEG IMX tapes are a muted green.
