Sony PVW-2650

Description

Superior Picture Quality: The PVW-2650 has superb playback picture quality, a result of its use of the world standard Betacam SP recording format. Betacam SP is a component recording format, in which the chrominance signals (R-Y, B-Y) are time compressed and recorded on one track by using CTDM (Compressed Time Division Multiplex) a technology originally developed by SONY. The luminance (Y) signal is recorded on a separate track so that cross colour and cross luminance effects do not exist in this system. This component two-track.
The performance advantages of Betacam SP can also be attributed to the use of the metal particle tape.The PVW-2650 can playback both metal particle tapes and oxide tape. Any metal tape recorded by the PVW-2800, PVV- P and BVW series Betacam SP VTRs, or oxide tape recorded by the BVW series VTRs, can be played back by the PVW-2650.
The PVW-2650 provides broadcast quality noiseless playback pictures within the range of -1 to +3 times normal tape speed due to the Dynamic Tracking technology originated by Sony. The highly advanced DT system has new head dither circuitry and computerized control to ensure accurate head tracking. The DT heads are mounted on a ceramic bimorph, with positional information derived from strain gauges and fed back to the control system. In the VARIABLE mode, continuous noiseless pictures are reproduced over the range of -1 to +3 times normal playback speed in 54 steps.
The PVW-2650 also features a JOG mode in which the tape is moved frame by frame in either direction in step with the rotation of the search dial. This mode also provides clear, still pictures.
Variable Speed Playback Memory: The PVW-2650 provides Dynamic Motion Control (DMC) playback. This function memories the desired tape speed within the DT range of -1 to +3 times normal speed and plays back noiseless pictures at that speed. The PVW-2650, equipped with the built-in DMC facility, can perform DMC editing when used as a feeder with the PVW-2800
High Audio Quality: The PVW-2650 provides two longitudinal audio channels. The tape speed of the format and the adoption of the proven DolbyTM C-type NR (Noise Reduction) give the PVW-2650 high quality audio performance-a wide dynamic range, even at high frequencies, minimum distortion and an excellent S/N ratio.
Long Playback Time: Accepts both L-size and S-size cassettes, giving playback times of over 90 minutes and 30 minutes respectively. Both grades of Sony Betacam SP videocassettes, the BCT series and the SBT series, can be used in the PVW-2650. For the highest possible performance, the BCT series is recommended.
Compact and Lightweight: Compactness and lightweight are key factors designed into the PVW-2650P, which weighs approximately 25kg (55lb 2oz), and is 5 units high (19-inch rack mountable). The power consumption is 130W.
High Speed Picture Search: Has a high speed picture search facility which provides recognizable monochrome pictures at up to 24 times normal speed in forward and reverse. At speeds up to ten times normal these pictures are reproduced in color. In the jog mode, tape movement accurately follows the rotation of the search dial in both directions.
Built-in Time Base Corrector: The PVW-2650 is equipped with a built-in TBC (Time Base Corrector) as standard, providing stable pictures without a requirement for additional time base correction. Advanced, high quality digital dropout compensation also ensures consistent picture performance.
TBC Remote Control: In addition to the TBC controls built into the PVW-2650 remote adjustments can be made with an optional BVR-50 connected via a D-sub 15-pin cable to the rear panel connector (TBC REMOTE).
Built-in Time Code Reader: Reading of both VITC (Vertical Interval Time Code) and LTC (Longitudinal Time Code) to the SMPTE format, together with user bits, is a standard feature of the PVW-2650.
Color Framing: PVW-2650 is free from color framing as long as signals are fed directly from the component signal source. However, when playing back the tape-recorded from the composite source, the color framing function is needed for keeping the video signal impairment to the minimum. The Color Framing System of the PVW-2650 is the combination of the 4-field capstan servo function using the off-tape CF (Color Framing) ID pulse and the off-tape VISC (Vertical Interval Subcarrier) function which matches the decoding axis to the encoding axis. As a result,superior composite output is achieved.
Character Display: The PVW-2650 is provided with a built-in character generator and its output can be superimposed on the signal from Video Output 3 or Monitor Output. It displays either time code (VITC/LTC/U-BIT) or CTL timer data read from tape. VTR function status, including shuttle tape speed, can also be displayed by accessing the setup menu. Furthermore, error number and status can be automatically displayed when an error is detected. Character display is On/Off switchable from the subcontrol panel.
