A4 Welcome to the AV-TC 300! 

Your Time Code Toolbox AV-TC 300 is a comprehensive state-of the-art product, 

which covers - according to its configuration - nearly all Time Code applications 

ever occurring in a studio. The newly designed operation structure using single 

dedicated buttons for everyday settings, and a setup menu for the rather basically 

adjustments makes the AV-TC 300 an easy-to-handle unit. Still we advise to keep 

the menu overview close to the unit. It may be a tool in itself suggesting solutions 

to very special tasks. Also make use of the note sheet (Appendix) to write down 

your basic settings, especially if the AV-TC 300 is operated by different people 

from time to time. (See M4.7 PROFILE) 

Should you wish to have a close look at the basic principles of SMPTE/EBU Time 

Codes, ask your dealer for our information brochure "Introduction to the Basic 

Principles of SMPTE/EBU Time Code“. 

Best Regards

The SDC-outputs deliver to each other an output signal, which is inverted in 

polarity. The information of both outputs is identical. According to EBU-norm 

(EBU interface for 625-line digital video signals at the 4:2:2 level of CCIR Recommendation 

601, Chapter 3, 1.2. Channel Coding, Second Edition, January 1992) 

the code is equivalent to „scrambled NRZI“. This code guarantees synchronising 

to the signal and reading the data independently from polarity.

Serial Interface RS485 

The serial interface RS485 of AV-TC 300 may control up to 250 devices via a 

common interface, e.g. a computer. For that every AV-TC 300 gets a device 

address (ID) which range between 1 and 250 (see M4.5.5). Commands, which 

are sent via bus, contain the ID and address a special device. This device 

evaluates the command and sends a return via bus (see protocol SONY+ID, 

M4.5.2). 

Connections 

RS485 is connected as a bus. Beginning and end must be properly terminated 

right. One end is terminated on the PC-card the other on the cable. The operating 

voltage is given by AV-TC 300 via 330 Ohm on pin 4. The following pin numbers 

of the PC-card relate to RS485-card #13601 of W&T.

actual choice is indicated by . A different framerate is selected using the cursor 

keys and . Press enter to confirm the selection. The menu display shows 

as receipt. 

As the AV-TC 300 automatically detects the used video standard and the resulting 

frame rates (25 frames for 625/25 frames and 30 DF for 525/30), the AUTO option 

is selected by factory. This AUTO setting is generally recommended. 

M1.2 DVITC 

The permitted range for the insertion of VITC data is limited to video lines 6 to 22 

in 625/25 (PAL/Secam) and to lines 10 to 20 in 525/30 (NTSC). These limits are 

set automatically according to the video norm. 

AV-TC 300 generates DVITC either in two single lines (2-LINES) or in a coherent 

block of maximal 16 lines (BLOCK). 

To modify the adjustments press enter to enable the 3 rd menu level. The actual 

choice of items can be checked using the keys and . Mode selections are:

Caution: 

We recommend that the two lines should not be adjacent. The last 

line should be at least two lines larger than the first. If only one line 

is adjusted, both values must be identical. According to the suggestions 

of the standard, both lines are set to "14" at the factory. 

M1.3 Jam Sync 

The adjustments of the programmable jam function are carried out in the submenu 

of this menu item, which is recalled with the enter key. The items of the submenu 

are selected with the and keys. The following items are available:

Indication of the amount to be added to the reader time. 

After selection of this menu item, an 8-digit time display 

(HOURS : MINUTES : SECONDS : FRAMES) appears in the inserted 

adjustment menu. Use the hours, minutes, 

seconds and frames buttons to select the corresponding 

block of values. The selected figures will flash. The 

and keys are used to enter the values of the desired 

offset time. Confirm the entry with enter. A minus 

offset of e.g. one second is achieved by entering 

23:59:59:00. 

Application: Time Code Regeneration, “Converter with Tolerance” 

The problem of normal Jam-Sync 

As a standard proceeding, a read Time Code is checked regarding time plausibility 

and up-counting sequence before it will be transferred to the Time Code generator. 

Such a check will not prevent frame jumps occurring in case of e.g. lack of 

synchronization between reader and generator. This special Jam-Sync mode 

improves the Time Code regeneration - at least if the recording time is limited. 

Functional description 

Only if the difference between the read Time Code and the actual generated value 

exceeds a threshold value (in this case = 3 frames), the read value will be transferred 

to the generator. Otherwise the generator will continue counting freely. This 

way the generator outputs a continuous Time Code without any frame jumps. 

A frame accurate lock after a start will be achieved by accepting all read values for 

a period of two seconds after the threshold has been exceeded. This overcomes a 

lost of synchronization during, for example “the run-up time of a VCR”. 

The generator remains in the „free-running mode“ if no more values will be read 

(infinite „flywheel“). 

With this proceeding please note: 

If the last reader value (2 seconds after exceeding the threshold) has been 

transferred while the reader Time Code is not yet phase-locked to the generator 

Time Code (e.g. if a run-up phase is delayed), it is possible that values will be 

generated continuously which constantly differ to the reader Time Code, difference 

up to 3 frames. 

In case the reader Time Code is not synchronized to the generator, a difference is 

being build up which will exceed the threshold. Then a correction will be made, i.e. 

instead of frequently generating one-frame jumps now - less frequently - 4-frames 

jumps occur. The shorter the time of processing (recording) the less will be the 

probability of frame jumps. 

Operating 

M1.3.1 

(Generator / Jam Sync / Mode) CVRT W/ TOLERANCE.


Page 18 

Application: Standard Conversion 

One application of Jam Sync is the conversion of Time Code between two standards, 

e.g. 25 Hz LTC to 525/30 D-VITC. AV-TC 300 detects this by seeing the 

different frame rates of reader and generator, and modifies the way of take-over 

the values in the jam functions. The converter modes CONVERTER and 

CVRT W/ TOLERANCE remain the same, but all other jam modes do the take-over 

of the values only once a second, in the last frame respectively. 

Particularly suitable for standard conversion is the jam mode 

CONT W/ TOLERANCE. As an example, a standard conversion from 625/25 D- 

VITC to 525/25 D-VITC will be shown, using two AV-TC 300. The first unit has a 

D-VITC reader and a LTC generator, and converts D-VITC to LTC. The second 

unit has a LTC reader and a D-VITC generator, and converts LTC to D-VITC. 

The video input of the first unit has to be fed with the 625/25 video signal. The 

units reads the D-VITC and converts it to a LTC with 25 Hz. Based on the factory 

setting (M4.7), the following setting has to be made: 

M1.3.1 GENERATOR / JAM SYNC / MODE CONVERTER 

Additionally, if required, in M1.3.3 an offset may be added. This offset is handled 

as a 625/25 Time Code. 

The video signal can be taken from the video loop output, processed by the video 

system converter, where it is converted to a 525/30 video signal. Then in the 

second AV-TC 300 the conversion of the 25 Hz LTC to a 525/30 D-VITC will be 

made. Thus, the LTC will be connected to the LTC input of the unit, and the video 

signal taken from the video system converter to the video input. Based on the 

factory setting (M4.7), the following setting has to be made: 

M1.3.1 GENERATOR / JAM SYNC / MODE CONT W/ TOLERANCE 

M3.7 INSERTION / SHOW OFF 

If required, in M1.3.3 an additional offset may be set (installed). This offset is 

handled as a 525/30 Time Code. Now at the video output of the second unit, the 

converted video signal can be taken, including a time-equal D-VITC relative to the 

source video.

2. READER 

Apart from the menu adjustment the following keys are available for the reader 


generator / reader 

time / user 

2.1 Display Selection 

With the generator / reader key the read data can be switched over to the 8-digit display. 

When the reader values are indicated, the diode on the left hand of the generator 

/ reader button is off. 

The time / user button serves to switch over between time and user values. When the 

time values are displayed, the adjacent diode lights up; when user values are 

displayed, the diode remains switched off. 

2.2 Indication of the active Reader 

The AV-TC 300 detects automatically which time-code is read out. The ltc / dvitc 

diode indicates the current time-code. If LTC is read, the diode is lit; if DVITC is 

read, it is off.

M2.4 Analysis 

The AV-TC 300 is able to show detailed information of the Time Code presently 

read. The information is inserted. Use the enter button to recall the following 

information:


Page 21 

1 Recognized video-norm from SDC. The following item 

are indicated: number of lines (625 or 525), frames per 

second (25 or 30) and word width (8 or 10 bits). 

2 Field of SDC. 

3 Framerate, which is detected from the read Time Code. 

4 DVITC, which is detected automatically. 

5,6 Data of DVITC reader. 

7,8 Data of LTC reader. 

M2.5 Framerate 

The AV-TC 300 reads the framerates 24, 25, 30 and 30dropframe. As the AV- 

TC 300 automatically detects the used video standard and the resulting frame 

rates (25 frames for 625/25 frames and 30 DF for 525/30), the AUTO option 

should be selected. This setting is generally recommended. 

The current setting is indicated by . A different framerate is selected using the 

keys and . Press enter to confirm the selection. 

M2.6 DVITC 

To increase the readout security of the DVITC, the comparator threshold used to 

differ between the "high" and "low" states of the DVITC signal may be adjusted.

DVITC is read out in two defined 

lines, the first and the last. 

If only one line is adjusted, just 

this line is read out. 

Number of the first line, in which DVITC should be read 

out. The line number refers to both fields. 

Number of the last line, in which DVITC should be read 

out. The line number refers to both fields. 

DVITC is separated from the video signal by a threshold. 

It depends on the right adjustment of the threshold 

whether an how safe the DVITC is read out. 




Select from:

Automatically detection of the 

threshold. Every DVITC value 

is read even it is not generated 

according to the standard, e.g. 

digitised analog Time Code. 

This adjustment may be disadvantageous 

during optimising: 

for the first three or four seconds 

after recognising the 

DVITC short interrupts happen. 

0 - 700MV Adjustable DVITC. The automatic

C3 Communication Protocol 

This chapter describes the communication between the AV-TC 300 and any 

computer and controlling device. In general the controlling device transmits 

messages first and receives a response in return of AV-TC 300. 

Another command may be sent, if the response to previous command has been 

received. Some commands require a back-up. For that the response may last up 

to 200ms. 

A sent data string must be coherent, i.e. no time gap >about 100 times of bit’s 

length (depends on the baud rate) resp. >10ms with baud rates >= 9600 baud is 

allowed. 

The received or sent data string looks as follows: 

Byte 1 Byte 2 Byte 3 Byte 4 Byte n+2 Byte n+3 Byte n+4
