Betacam
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 analog Betacam, Betacam SP and Digital Betacam, 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 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 cassettes are available in two sizes: S (short or small) and L (long or large). 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 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 and 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 video tape format in history. However, by 2008, although Betacam remained in use in the field and for archiving, new tapeless digital products had led to a phasing out of Betacam products in television studio environments.[citation needed]
The original Betacam format was launched on August 7, 1982 as a relatively inexpensive cassette based physical format. It is an analog component video signal format, storing the luminance (Y), in one track and the chrominance, on another as alternating segments of the R-Y and B-Y components performing Compressed Time Division Multiplex, or CTDM. This splitting of channels allows higher quality recording with 300 lines of horizontal luminance resolution and 120 lines chrominance resolution. Image quality is significantly improved compared to domestic Betamax and the professional U-Matic formats.
The original Betacam cassettes, loaded with ferric-oxide tape, were identical in overall design and size (15.1 × 9.5 × 2.5 cm) to consumer-grade Betamax, introduced by Sony in 1975. Betacam cassettes could be used in a Betamax VCR; likewise, a blank Betamax tape would work on a Betacam deck. However, in later years, Sony discouraged this practice, suggesting that the internal tape transport of Betamax cassette was not well suited to the faster tape transport of Betacam. In particular, the guide rollers tend to be noisy.[citation needed]
Although there is a superficial similarity between Betamax and Betacam in that they use the same tape cassette, they are incompatible formats. Betamax records relatively low-resolution video using a heterodyne color recording system and only two recording heads, while Betacam uses four heads to record in component format, at a much higher linear tape speed of 10.15 centimetres per second (4.00 in/s) compared with Betamax's 1.87 centimetres per second (0.74 in/s), resulting in much higher video and audio quality. A typical L-750 length Betamax cassette that yielded about 3 hours of recording time on a Betamax VCR at its B-II Speed (NTSC), or on PAL, only provided 30 minutes' record time on a Betacam VCR or camcorder. Another common point between Betamax and Betacam is the placement of the stereo linear audio tracks.[citation needed]
Betacam was initially introduced as a camera line along with a video cassette player. The first cameras were the BVP-3, which utilized three Saticon tubes, the BVP-30, which utilized three Plumbicon tubes, and the BVP-1, which used a single tri-stripe SMF (Saticon Mixed Field) Trinicon tube. These three cameras could be operated standalone, or with their docking companion VTR, the BVV-1 (quickly superseded by the BVV-1A), to form the BVW-1 (BVW-1A) integrated camcorder. Those decks were record-only. The only transport controls on the deck were eject and rewind. The docked camera's VTR button started and paused the tape recorder. Later the Betacam SP docking decks had full transport controls (except a record button) but tapes could not be played back except in the camera's viewfinder in black-and-white only. Sony then came out with the playback adapter, the VA-500, a separate portable unit that connected via a multi-pin cable and had a composite video out jack for color playback. At first color playback required the studio source deck, the BVW-10, which could not record, only play back. It was primarily designed as a feeder deck for A/B roll edit systems, usually for editing to a one-inch Type C or three-quarter-inch U-matic cassette edit master tape. There was also the BVW-20 field playback deck, which was a portable unit with DC power and a handle, that was used to verify color playback of tapes in the field. Unlike the BVW-10, it did not have a built in time base corrector (TBC).
