Index 1-1 (E)

To take best advantage of the many features of this unit, note the following important points.

Usable cassette tapes (see page 3-3(E))

Use only metal cassette tapes with this unit. Do not use oxide tapes.

Reference video input (see page 3-5(E))

When recording or playing back videotapes on this unit, always input a composite video signal synchronized with the video signal to be used to the REF. VIDEO INPUT connector. Especially when recording and editing, failure to input a reference video signal to the REF. VIDEO INPUT connector will prevent the built-in time base corrector (TBC) from functioning correctly, causing picture breakup. Even if you are recording only audio signal or time code, do not fail to input a reference video signal.

Input video signal type selection (see page 4-5(E))

For recording, it is important that the VIDEO IN switch on the subsidiary control panel is correctly set to match the type of video signal input. In particular, when inputting a component signal, set this switch to the "Y-R,B" position, and set the component signal input connector selection switch on the rear panel to the appropriate position. If these switches are not set correctly, not only will recording not be possible, but the input signal will also not appear on the monitor.

Setting the cassette record-inhibit plug (see page 3-4(E))

Recording on a cassette is impossible when its record-inhibit plug is pushed in. If the record-inhibit plug is pushed in on the cassette you are going to use, either use a new tape, or pull out the plug and use the tape after making sure that it contains no important material.

Controlling tape transport remotely (see page 7-3(E))

The tape transport buttons on this unit are normally disabled when the REMOTE indicator is lit. However, you can use these buttons if you set the LOCAL ENABLE menu item to ALL ENABLE. The factory default setting for this item is STOP & EJECT.

Storing in a rack

When installing this unit in a standard 19-inch rack, you can stack up to three units in one rack. When stacking four or more units, be sure to leave space equivalent to one unit height, or 44.45 mm (1 3/4 inches) between units.

Chapter 1 Overview

This chapter overviews the features of the UVW-1800/1800P.

Features.... 1.2 (E)

The UVW-1800/1800P is a Betacam SP videocassette recorder, capable of recording and playing back composite video, component video and analog audio signals. With an external control unit connected, jog and shuttle functions are available, and the unit can be used as the recorder in an editing system.

Betacam SP format

Excellent video and audio characteristics

Compared with a conventional format, Betacam SP format provides better video and audio performance, with improved signal-to-noise ratio, frequency characteristics, and detail reproduction, and greatly enhanced overall video and audio quality.

Compatibility with other Betacam SP VTRs

A metal tape cassette recorded on this unit can also be played back on other Betacam SP VTRs. Again, metal tape cassettes recorded on other Betacam SP VTRs can be played back on the UVW-1800/1800P. The cassette size is detected automatically.

Full range of recording and playback functions

Built-in time code generator and reader

The built-in time code generator allows the unit to record time codes (LTC or user bits) simultaneously with the video and audio signals. The built-in time code reader allows the unit to read time codes (LTC or user bits) from a tape.

Built-in time base corrector (TBC)

The built-in time base corrector allows you to obtain a stable playback picture with no horizontal jitter or color fluctuation.

Microprocessor servo system

Four microprocessor-controlled DC motors provide direct drive for the drum, capstan and reels, enabling quick and accurate tape access.

Audio noise reduction

Longitudinal audio tracks 1 and 2 use the same Dolby C-type noise reduction ²¹ as a conventional Betacam SP system. These circuits are always operating when recording or playing back.

1) Because this unit does not record the AFM carrier wave, noise may be heard when tapes recorded on this unit are played back by other VTRs in the BVW series. If necessary, lower the audio levels of channels 3 and 4 on the other VTR.

2) Dolby noise reduction manufactured under license from Dolby Laboratories Licensing Corporation. "DOLBY" and the double-D symbol DO are trademarks of Dolby Laboratories Licensing Corporation.

Other features

Compact, power-saving design

The unit is light and simple, and very energy-efficient.

Menu-based set-up system

All the initial settings for system operation conditions and so forth are accessed through a simple menu system, from the subsidiary control panel.

Remote control function

The unit can be operated from a remote control unit through the RS-422A serial interface.

It is also possible to use the CONTROL S connector on the front panel to connect a simple remote control unit (SIRCS type remote control unit such as an SVRM-100) to carry out search operations.

Digital hours meter

The digital hours meter keeps cumulative totals of four values: the total hours powered on, the drum rotation time, the tape running time, and the numbering of threading/unthreading operations. These are displayed as superimposed text on the video monitor.

Superimposed text output

The VIDEO 2 (SUPER) OUTPUT connector provides a monitor video output which can have various information (time codes, tape speed, system settings, etc.) superimposed on it. The superimpose function can be enabled or disabled as required.

S-Video connectors

With VTRs or other peripheral equipment having S-Video connectors, these connectors provide a high-grade interface for video signal transfer.

Self-diagnosis functions

If an operating fault occurs, the system attempts to diagnose the problem, and produces an error code on the time counter display and superimposed video output.

Alarm indications

If an erroneous operation or connection is made, the system superimposes information on the monitor screen giving the nature of the error and actions to be taken. The cause of the problem is also indicated in the time counter display.

Phase Adjustments

When using two or more players, as in an A/B roll editing system, phase synchronization of the signals (i.e. system sync) is necessary and for composite signals only, the subcarrier phase must also be in sync. If not, picture instabilities or color break-up may occur at edit points. After configuring the editing system, use a Vectorscope to adjust the sync and subcarrier phase of the recorder and players. Subcarrier phase adjustment is necessary only when using composite signals.

Connections for phase adjustment

Phase adjustment procedure

1 Press the SCH button on the Vectorscope.

The Vectorscope switches to "SCH" mode.

2 Press the B channel button on the Vectorscope.

This displays the black burst signal from the switcher.

3 Press the EXT button on the Vectorscope.

This switches the Vectorscope to external synchronization mode.

(Continued)

Phase Adjustments

4 Adjust the phase synchronization control on the Vectorscope so that the sync and subcarrier phases are close to the reference line.

5 Output the player 1 signal from the PVE-500.

6 Press the A channel button on the Vectorscope.

This displays the sync phase and subcarrier phase (composite signals only) of the signal from player 1.

On the subsidiary control panel of player 1, adjust the SYNC and SC adjustment controls, using a Phillips screwdriver, so that the output from player 1 on channel (A) is in correct phase alignment with the black burst signal on channel (B).

Note

When component signals are used the subcarrier phase does not appear.

8 Output the player 2 signal from the PVE-500.

Repeat steps 6 and 7 to adjust the sync and subcarrier phase of the output from player 2.

Chapter 6 Time Data

The time data used by the UVW-1800/1800P for both recording and display include CTL signal count values, longitudinal time codes (LTC), and user bit data. This chapter describes how to display time data, and how to set LTC and user bit values.

Note

If you power off this unit while it is in the process of saving the settings, settings may be lost. Wait until saving is completed before powering the unit off.

Internal time code generator running modes

There are two different modes of operation for the internal time code generator, selected by the RUN MODE setting as follows.

"FREE RUN": The time code generator begins to run from the instant the preset value is saved.

"REC RUN": The time code generator runs only during recording.

Presetting the time data value to reflect real time

In the menu, set RUN MODE to "FREE RUN", and set the time data value to the current time.

Synchronizing the Internal Time Code Generator With an External Time Code Generator

If a time code signal (LTC values) is input to this unit, the internal time code generator is automatically synchronized to the time code value input from an external source. Using this function, it is possible to have a number of VTRs all set to synchronized time codes, and to copy time codes precisely from one tape to another.

Connections and switch settings

Carry out the following connections and switch settings.

Connections and switch settings

When an external time code is input, the running mode of the internal time code generator is as follows.

RUN MODE: Automatically set to "FREE RUN."

DF MODE (for UVW-1800 only): Automatically set to either drop-frame mode or non-drop-frame mode according to the mode of the input time code.

After setting the TC IN selector switch to EXT position, the internal time code generator begins to run in synchrony with the external time code generator.

The internal time code generator continues to run in the same way even if the external time code generator is disconnected.

Checking the internal time code generator counting

Stop the tape, and press the REC button.

Check that the same value as the input time code value is displayed.

If the unit is suddenly moved from a cold to a warm location, or used in a very humid place, moisture from the air can condense on the head-drum. If the tape is run in this state, the tape may stick to the drum, in which case it is highly likely to be damaged. To lessen the risk of this occurring, this unit is fitted with a condensation detection system.

If moisture condenses on the head-drum while the unit is operating

The indication "HUMID !" appears in the time counter display. The following indication also appears on the monitor.

Condensation warning indication

If this happens, the cassette is ejected automatically.

Before resuming the operation, wait until the alarm message disappears, without turning the unit off.

If the condensation warning appears immediately after powering on

Leave the unit powered on and wait until the indication disappears. While the indication is present, it is not possible to insert a cassette.

Once the warning indication disappears, the unit is ready for use.

Regular Checks and Maintenance

Digital Hours Meter

The digital hours meter keeps a cumulative count of the total operating time, the drum rotation time, the tape transport operating time, and the number of threading and unthreading operations. These counts can be displayed on the monitor and time counter display; use them as guidelines for scheduling maintenance. Consult your Sony service representative about necessary periodic maintenance checks.

Digital hours meter indications

The digital hours meter provides the following four display items.

T1: OPERATION

Cumulative total of hours unit is powered on, in units of 10 hours

T2: DRUM ROTATION

Cumulative total of hours of drum rotation with tape threaded, in units of 10 hours

T3: TAPE RUNNING

Cumulative total of hours of tape transport operation, in units of 10 hours

CT: THREADING

Cumulative number of tape threading/unthreading operation pairs, in units of 10 operation pairs

Except for the total operation time, there are two counts for each item: the cumulative total from manufacture, and a 'trip' count resettable.

Displaying the digital hours meter

Press the HOURS METER button.

Monitor display

All four counts appear.

The four-digit value to the left of the slash is the resettable trip count, and the right value is the cumulative total from manufacture.

Time counter display

One of the four indications appears. Use the □ and ↓ buttons to change the item displayed.

Initially, only the trip value appears. Press the ☐ button to display the cumulative total to the right of the slash, as long as the button is held down.

Digital hours meter

Ending the digital hours meter display

Press the HOURS METER button.

Resetting the trip values

Consult your Sony service representative.

Head Cleaning

Clean both the video and audio heads using the special BCT-5CLN cleaning cassette. Follow the instructions for the cleaning cassette carefully, as improper use can damage the heads.

Cleaning procedure

Insert the cleaning cassette, hold down the PLAY button and press the EJECT button. This carries out a five-second cleaning operation. The EJECT indicator flashes during this period, and all tape transport buttons other than the EJECT button are disabled.

Notes

• Up to three consecutive cleaning operations are possible. Cleaning above this level may damage the heads.
• Be sure the unit is not left with the cleaning cassette in place, as this can cause damage to the heads.

Alarm Messages

There are a number of messages which may appear on the monitor screen during operation. (A message also appears in the time counter display.)

Alarm messages

These alarm messages indicate misoperations or problems with the unit such as condensation on the drum.

To display these messages on the monitor screen, the monitor must be connected to the VIDEO 2 (SUPER) OUTPUT connector, and the CHARACTER switch on the subsidiary control panel must be in the ON position. It is possible to disable the display of warning indications in the menu system, by setting the ALARM and REF. ALARM items to OFF.

For details of the menu settings see the section "Menu Operations" (page 7-8(E)).

If an alarm message is indicated, take appropriate action according to its contents.

Tape problems
Symptom	Cause	Remedy
Recording is not possible.	The record-inhibit plug on the cassette is pressed ina).	Pull out the plug, or use a different tape.
The tape transport controls (PLAY, F FWD, REW buttons etc.) do not operate.	The REMOTE/LOCAL switch is in the REMOTE position, and the LOCAL ENABLE menu setting is "STOP & EJECT" or "ALL DISABLE"a).	Set the REMOTE/LOCAL switch to LOCAL, or change the menu setting to "ALL ENABLE".
	No cassette is loaded3).	Insert a cassette.

Time code problems
Symptom	Cause	Remedy
It is not possible to preset the time counter display to an arbitrary value.	The TC IN selector switch is in the EXT positiona).	Set the TC IN selector switch to the INT position.
	The CTL/LTC/U-BIT switch is in the CTL position.	Set the CTL/LTC/U-BIT switch to the LTC or U-BIT position. (It is not possible to preset time counter values.)
	The REMOTE/LOCAL switch is in the REMOTE position, and the LOCAL ENABLE menu setting is "STOP & EJECT" or "ALL DISABLE"a).	Set the REMOTE/LOCAL switch to LOCAL, or change the menu setting to "ALL ENABLE".
Although the tape transport is operating, the time counter value does not change.	The MENU button, TC PRESET button or HOURS METER button has been pressed.	Press the button again, to exit from menu setting mode, time code presetting mode or Hours meter mode, as the case may be. (In either of these modes, the time counter display does not show time counter information.)
	The time counter display is showing user bit data.	Set the CTL/LTC/U-BIT switch to the LTC or CTL position.

a) In these states an alarm message appears both on the monitor screen and time counter display.

Monitor problems
Symptom	Cause	Remedy
A "V" appears on the screen.	The TBC DELAY menu item is set to "VIDEO DELAY".	Set TBC DELAY to "SYNC DELAY". (The UVW-series has a built-in time base corrector. Therefore, in editing mode or video EE mode, the output video signal is delayed exactly 8 lines behind the reference signal. This means that when the TBC DELAY setting is "VIDEO DELAY", the video appears 8 lines lower on the monitor, and a "V" appears. However, even if the TBC DELAY item is set to "SYNC DELAY", if the monitor is synchronized to an external reference, a "V" also appears. This is not a malfunction.)
	A reference video signal is not being input. Alternatively, the input video signal is not synchronized to the reference signala) .	Input a reference signal which is synchronized to the input video signal. Alternatively, use the REF. VIDEO INPUT connector on this unit in loop-through mode, and connect to the player REF. VIDEO INPUT. (In editing mode, the servo synchronizes to the input video signal. Therefore, if the input video signal and reference video signal are not synchronized, the time base corrector and servo will not synchronize, and therefore the picture will break up. Recording in this condition, however, will not affect the quality of the recording.)
The time code (or other time counter indication) superimposed on the monitor is one frame behind.	The time code is being displayed in the top third of the screen.	Move the display position down. (When using a superimposed time code, and recording on another VTR avoid the top third of the screen. In the UVW-series, the time code is superimposed as soon as read, and therefore even discontinuous time information such as user bit data can be displayed with the minimum of delay. However, since the new data value is still being processed while the beam is scanning the top third of the screen, the data from the previous frame appears if the time code is displayed within this area.)
The picture does not appear in video EE mode.	The connector to which the video signal is input does not match the setting of the VIDEO IN selector switch.	Make the setting of the VIDEO IN selector switch match the connector to which the video signal is input. When inputting a component signal, also set the component input connector selection switch correctly.
No superimposed information appears on the monitor screen.	The CHARACTER switch is in the OFF position.	Set the CHARACTER switch to the ON position.
	The monitor is not connected to the VIDEO 2 (SUPER) OUTPUT connector.	Connect the monitor to the VIDEO 2 (SUPER) OUTPUT connector. (To display superimposed information, the monitor must be connected to the VIDEO 2 (SUPER) OUTPUT connector.)
The monitor screen is too bright.	The monitor INPUT connector 75 Q termination switch is in the OFF position, or there is no terminating device.	Set the monitor INPUT connector 75 Q termination switch to the ON position, or connect a terminating device.
The monitor screen is too dark.	The 75 C/termination of the video signal input is duplicated. For example, when using the REF. VIDEO INPUT connector for a loop-through connection, the 75 a termination switches of the REF. VIDEO INPUT connector and the VIDEO INPUT connector are both set to the ON position.	Set the 75 ft termination switch of the connector being used for a loop-through connection to the OFF position.
The video image is too dark when editing a composite video signal.

a) In this state an alarm message appears on the monitor screen and time counter display.

Glossary

A/B roll edit

An edit in which two or more players are used to create special effects such as dissolve and wipe, and one recorder is used to record the results of the edit. Using an editing controller allows efficient control of the VTRs and very precise editing.

B-Y signal

A chrominance signal determined by subtracting the Y (luminance) signal from the B (blue) signal. One of the component signals.

Bridging connection

A connection which allows a signal input to an input terminal to pass through the unit and exit from an output terminal as input to external equipment. Also called loop-through connection.

Capstan

A drive mechanism that moves the tape at a specific speed. Its rotation normally synchronizes with a reference sync signal.

Chrominance signal

Color signal containing color information such as hue and saturation. Also called C signal.

Color frame

The color subcarrier phase, whose one cycle consists of two frames (four fields) in NTSC format and four frames (eight fields) in PAL format.

Color framing

Maintenance of continuity in the color subcarrier phase between one frame and the next, for the purpose of avoiding noise on the picture.

Component signal

A video signal consisting of a luminance signal (Y) and two chrominance signals (R-Y, B-Y).

Composite signal

A composite video signal containing video, burst, and sync signals.

CTL

Abbreviation of control signal. A pulse signal recorded on a longitudinal track of the tape in units of fields. Counting this signal allows the number of frames to be used to display the tape running time. It is also used as a control signal to adjust the relationship between the scanning position of the video heads and tape movement during playback to match that during recording.

Drop frame mode

In NTSC format, the actual number of frames per second is approximately 29.97, while that for the time code is specified as 30. Drop frame mode is a mode in which the time code is advanced in such a way that the difference in frame value between real time and the time codes is corrected. In this mode, two frames are skipped at the beginning of each minute, except for every tenth minute, so that the frame value for time codes matches that for real time.

EE mode

Abbreviation of Electric to Electric mode. Video and audio signals are supplied to the VTR's internal circuits, but not to the recording heads.

External synchronization

Synchronization of the signals and tape transport of a VTR with those of a reference VTR.

IRE

A unit for expressing video level as determined by the Institute of Radio Engineers (now called the Institute of Electrical and Electronic Engineers).

LNG recording

Abbreviation of longitudinal recording. A method of recording audio signals by radio frequency bias method on the longitudinal track of the tape using the fixed head.

LTC

Abbreviation of Longitudinal Time Code. A time code recorded in a separate track at the edge of the tape.

Luminance signal

The signal that determines the brightness of the picture. Also called Y signal. One of the component signals.

Metal tape

Magnetic tape coated with microscopic particles of metal dispersed in a liquid binder. It allows high-density recording.

Moisture condensation

Condensation of moisture on the tape transport mechanisms. If moisture condenses on the head-drum, the tape adheres to the drum and causes malfunction.

Non-drop-frame mode

A mode of advancing the time code in such a way that the difference in frame values between real time and the time code is neglected. Using this mode produces a difference of approximately 86 seconds per day between real time and time code, which causes problems when editing programs in units of seconds using the number of frames as a reference.

Oxide tape

Magnetic tape coated with microscopic particles of ferric oxide dispersed in a liquid binder.

R-Y signal

A chrominance signal determined by subtracting the Y (luminance) signal from the R (red) signal. One of the component signals.

Reference video signal

A video signal consisting of a sync signal or sync and burst signals, used as a reference.

SMPTE

Society of Motion Picture and Television Engineers.

S/N ratio

Abbreviation of Signal-to-Noise ratio. The higher the S/N ratio, the less noise and higher the picture quality.

Search mode

A VTR mode used when searching for specific scenes, by viewing the video output or time codes while playing back the tape at various speeds in forward or reverse direction.

Servo lock

Synchronizing the drum rotation phase and tape transport phase with a reference signal during playback and recording so that the video heads scan the tape in the same pattern during playback and recording.

Superimpose

To put a picture (or a set of characters) onto another so that both can be seen at the same time.

S-video input connector

A connector that inputs Y (luminance) and C (chrominance) signals separately to reduce interference between Y and C signals, and to help reproduce noiseless images.

Sync signal

A reference signal consisting of vertical and horizontal sync signals used for synchronizing the scanning patterns of the video camera and the monitor.

TBC

Abbreviation of Time Base Corrector. Electronic circuits to electrically stabilize the playback signals by removing color variation and roll in the playback picture caused by irregularity in drum rotation and tape movement. Time base correction reduces deterioration of picture quality when transmitting or copying playback signals.

Time code

Signals recorded on the tape to supply information on tape position such as the hour, minute, second and frame, to assist in setting edit points or searching for particular scenes. There are two types of time code: LTC and VITC.

Tracking

Electrically controlling the video head so that the playback phase matches the recording phase of the tape. Especially when playing back the tape with a VTR other than the one used for recording, adjusting the tracking prevents noise from appearing on the picture.

User bits

Sections of the time code consisting of a total of 32 bits used for recording information such as the year, month and day, tape ID number or a program ID number.

Glossary

V-blanking

The portion of the video signal that occurs between the end of one field and the beginning of the next. During this time, the electron beams in the cameras and monitors are turned off so that they can return from the bottom of the screen to the top without showing traces of movement on the screen. When the position of V-blanking is not adjusted correctly, a horizontal black bar appears on the screen.

VBS

Abbreviation of Video, Burst and Sync. A composite signal consisting of video signal, burst signal and sync signal.

VITC

Abbreviation of Vertical Interval Time Code. Time code recorded on a video signal track during V-blanking interval. It can be read correctly even during slow or still picture playback.
