Timecode reader software
PCTimecode v2.0 Trial and Supervisor
Internal clock function
It will continue to count seconds even if you take off the cable.

Trial mode is equipped with a basic performance necessary for decoding.
You can import the timecode directly to Excel.
*System Requirements
Windows XP SP3 or later
.NET framework 2.0 or later
Audio input Device that can be recorded in 48000Hz, 8bit, mono or 96000Hz, 8bit, mono.
MS Excel, If you want to logging.
New function
Internal clock, like JamSync.
It dose not display frames.
Accuracy of the Internal clock will less than 1 second per hour.


Installation and starting

 
PCTimecode.msi
Installation package		 Installation:
Unzip "PCTimecode.zip".
To start the installation, click "PCTimecode.msi".

There is no problem if there are warning of unknown publisher leaves during the installation.

Application folder to be created is 60KB or less.
 
PCTimecode
Shortcut		 Starting:
You can icon to the left on the desktop, double click it to start.
(or Start->Programs->PCTimecode)

If you want to logging a timecode to start the MS Excel.
Mechanism of PCTimecode:
 diaglam
You can get the text on the form of other application using the MS Excel macro function.
To do this you need to know the class name of other application.
I gave an original class name to PCTimecode.
//Form->PCTimecode//
//Timecode->Eidt//
You can get the Timecode text on PCTimecode using the "FindWindowEX" of Windows API.

If you unfamiliar with the macro.Please use a sample.xls.

*Mr.timecode moved to the next job.
When you press the decode button.
(Signal not found.)

If the signal is not coming.
1.You do not input the timecode.
2.You did not select a recording device.
3.You had turn the volume down or mute of a recording device.
4.you connect a USB device with microphone.

Can you please make sure to operate the recording device. (not output, not playback)
When you press the decode button.
(Decode succeeded.)
If decoding fails.
1.Value of the signal is low.
2.Not SMPTE LTC
3.Not 23.98～60fps
(Supervisor mode)
or reverse.

If displayis distorted.
1.Graphics performance　is not enough.

There is a case to beresolved by uncheck "Smooth edges of screen fonts" in "Performance Options"

 Caution Crystal of the computer is not a high accuracy, it does not completely synchronized. Slip of 2~3frames per hour will occur.


Analysis

Bit 10, 11, 27, 43, 58, 59 Value of the flag bits.
Frame Rate Frame rate of the received LTC.
Sampling Rate Sampling rate of decoding.
Threshold Threshold to distinguish between 0 and 1.
TC1second Milliseconds in real time for 1second of TC. (999, 1000 or 1001ms)
Increment Time resolution of the computer.
(It is desirable 35ms or less to use the internal clock.)


Product key

It operates in "Trial mode" when you download and install.

How to input a timecode to the computer

The timecode signal is input to Line-in of the computer.
Important:
Level of the timecode signal must not exceed absolute maximum input of the computer.

/*Please input at your own risk of the user.*/
/*Author of this application is not responsible.*/
 Circuit diagram for DIY
Circuit diagram for DIY
BNC-J to 3.5mm stereo mini plug (without attenuator) cable.
/*Input max 2Vp-p*/
Input the line-in of computer the timecode signal.
Microphone input uses absolutely should not.
If more than 2Vp-p, please always use an attenuator.(-12.5dB ~ -30dB)
