U-matic is additionally accessible in a abate cassette size, clearly accustomed as U-Matic S. Much like VHS-C, U-Matic S was developed as a added carriageable adaptation of U-Matic, to be acclimated in smaller-sized S-format recorders such as the above Sony VO-3800, as able-bodied as the after VO-4800, VO-6800, VO-8800, BVU-50, BVU-100 and BVU-150 models from Sony, amid others from Sony, Panasonic, JVC and added manufacturers. To abbreviate weight and aggregate in the field, carriageable recorders had an alien AC ability supply, or could be operated from Ni-cad rechargeable batteries. The amount point of the VO alternation was aggressive against educational, accumulated and automated fields, featured asymmetric audio connectors, and did not about accommodate SMPTE time cipher (although one or two companies offered after-market modification casework to install longitudinal time code). The VO-3800 was abundantly metal, which fabricated the assemblage heavy, but still technically portable. The VO-4800 had the aforementioned functionality as the VO-3800, but at a abundantly bargain weight and size, by replacing abounding apparatus with plastic. The VO-6800 added the advance of a long, attenuate array accustomed ("candy bars") that acceptable accumulator of the batteries in a trouser pocket. Common archetypal numbers for these batteries were NP-1, NP-1A and NP-1B. The VO-8800 was the aftermost of the carriageable VO alternation to be produced by Sony, and featured solenoid-controlled transport.
The Sony BVU alternation added longitudinal and vertical breach SMPTE time code, counterbalanced audio XLR connectors, and heavier-duty carriage features. The BVU-50 enabled recording in the acreage but not playback, and the BVU-100 acceptable both recording and playback in the field. Carriageable recorders were affiliated to the camera with a multi-conductor cable concluded with multi-pin connectors on anniversary end. The cable agitated bi-directional audio, video, synchronization, almanac on/off control, and power. Aboriginal flat and all carriageable U-Matic VCRs had a drawer-type apparatus which appropriate the band to be inserted, followed by chiral cease of the drawer (a "top-loading" mechanism). After flat VCRs accustomed the cassette from a anchorage aperture and the cassette was pulled into and built-in in the carriage (a "front-loading" mechanism).
S-format tapes can be played aback in earlier top-loading accustomed U-Matic decks with the aid of an adapter (the KCA-1 from Sony) which adapted about an S-sized tape; newer front-loading machines can acquire S-format tapes directly, as the tapes accept a aperture on the base that rides forth a tab. U-Matic S tapes had a best recording time of 20 minutes, although some band manufacturers such as 3M came out with 30-minute tapes by loading the cassette with a thinner tape. It was the U-Matic S-format decks that ushered in the alpha of ENG, or Electronic News Gathering.
Some U-Matic VCRs could be controlled by alien video alteration controllers, such as the cuts-only Sony RM-440 for beeline video alteration systems. Sony and added manufacturers such as Convergence, Calaway, and CMX Systems produced A/B cycle systems, which acceptable two or added VCRs to be controlled and synchronized for video dissolves and added motion effects, affiliation of the appearance generator, audio controllers and agenda video furnishings (DVE).
In the aboriginal 1980s, Sony alien the semi backwards-compatible high-band or BVU (Broadcast Video U-matic) format, and the 'original' U-matic architecture became accustomed as low-band. This high-band architecture had an bigger colour recording arrangement and lower babble levels. BVU acquired immense acceptance in ENG and area programme-making, spelling the end of 16 mm blur in accustomed production. By the aboriginal 1990s, Sony's ½-inch Betacam SP architecture had all but replaced BVU alfresco of accumulated and 'budget' programme making. Sony fabricated a final advance to BVU by added convalescent the recording arrangement and giving it the aforementioned 'SP' suffix as Betacam. SP had a accumbent resolution of 330 lines.2 First-generation BVU-SP and Beta-SP recordings were adamantine to acquaint apart, but admitting this the autograph was on the bank for the U-matic family, due to built-in problems with the format.generational degradation. Use of a time-base corrector (TBC) or "dub" cable were methods of aspersing multi-generational affection loss. The TBC regenerates the accompany tip allocation of the video signal, convalescent playback reliability. The dub, demodulated (or "demod") cable was a multi-conductor cable that baffled a allocation of video circuitry, aspersing addition noise.its additionally acclimated U-matic cassettes as a accumulator medium.
