DtGrabber+ application icon: 5.2. DtGrabber+ Application General Layout 1 2 5 3 6 4 7 8 9 10 Application general view 1. Menu Bar: The top area of the DtGrabber+ application contains four menus: Recorder, Tools, Adapter and Help. 2.
DTC-325 5. Record Option: This area provides controls to select between Single File recording or Multiple File recording. For Single File recording, the loop recording can be selected. For multiple files, a specific number of file can be defined or unlimited number of files can be created through the setting of auto-erase rules detailed in section 4.3.3 6. Estimates View: This area displays estimates for File Duration, File Size and Total Size required for your recording configuration. 7.
DTC-325 For SDI input signals, only one LED (signal) is present. After selecting the SDI Input Mode, video input’s number of lines and signal rate are displayed. Specific settings as Huffman compression and recording method (Video Frame/Full Frame, 8bits/10bits) are available. NOTE: for 10-bit full frame SDI recording with a DTU-225 or DTU-245 it is recommended to use Huffman compression.
DTC-325 Below the File Name setting box, three sub areas: File Type, Record Option and Estimates are provided. File Type File Type selection Specify the type of Record file control: Duration (HH:MM:SS), by size (MB) or manually controlled. Record Option Record Option settings The Record Options permit you to select between Single File Recording and Multiple File Recording. For simple recording on the spot, select “Single File Recording” for the creation of a unique file.
DTC-325 Estimates View Estimates View This view provides estimation of File Duration and File Size and the overall size required for your recording depending on your settings. For instance in the case of continuous recording with 50 multiple files of 10 minutes each at a rate 31.6 Mbps, one file will requires 2263 MB and the continuous recording will requires 110.5 GB approximately. DtGrabber+ will check available space in regards with those estimates to validate the start of your recording. 5.3.4.
DTC-325 When incoming the data speed is higher than the disk capacity, this will result in Buffer overflow and data loss. When overflow occurs, the led turns to red then orange and the “overflow” message will be reported. (See section 5.3.5 for Message Bar and 5.4 for DtGrabber+ logs explanation) Control Area – Buffer Overflow If the overflow persists, the application will try periodically to restore itself by purging the buffer.
DTC-325 Note that the memory spaces displayed refer only to the actual Record done by the instance of the application and doesn’t take into account other instance of DtGrabber+ that may be running simultaneously on the same host PC. 5. Disk Available Space. This monitor displays the remaining space on the selected disk. In case the user starts a recording exceeding the available disk space, the following pop-up message will be displayed and the recording will be cancelled.
DTC-325 5.4. DtGrabber+ Messages and Logs 5.4.1. Application Messages The DtGrabber+ application generates messages in the Message Bar, in a Log File and as SNMP Trap if enabled so. Three levels of message are considered: INFO (Information), WARN (Warning) and ALAR (Alarm) for Alarm messages when recording or the quality of the recording is affected.
DTC-325 5.4.2. Message Logging All messages generated by the application are logged into the file “DtGrabberLog.txt” which is created automatically into the Record File directory. The following provides an example of logs generated by the application with a Multiple File recording with auto-erase rule for maximum 5 files. It provides details about times where file are created and deleted. In this example, a TS Sync loss is reported.
DTC-325 5.5. DtGrabber+ Tools 5.5.1. Merge tool After recording with multiple file option, one may need to rebuild the original signal from sequentially created files. For this purpose, the merge tool was created. To launch the tool, access the following menu: Tools->Merge Merge tool – Access the merge tool from the Tools menu From the Merge Files window, select first your input files from the “Select” button then click on [Merge] button to perform the merging.

Message Logging options From this window, the user can enable or disable the Message Logging, but can also specify the Log File Name.
DTC-325 DtGrabber+ Options settings – Disk Monitor CAUTION: Do note that recording will not start if the Disk Available Space is less than the specified minimum size. Unless the “Cancel start of recording if not enough overall disk space” checkbox is not checked. 5.6.3. File options Timestamping in the filename can be achieved by using a set of specific tags: %Y for year, %M for month, %D for day, %H for hour, %m for minute and %S for second.
DTC-325 DtGrabber+ Options settings – File When recording multiple files, the File index keeps incrementing each time a new file is created, BUT the index is reset to ‘1’ every time a recording is restarted. For critical and optimal disk usage, it is necessary to keep the File Index increasing each time a new file is done and independently if the server was rebooted, the application restarted or the recording task restarted. To enable this, uncheck the “File Index” checkbox.
DTC-325 DtGrabber+ Options settings – SNMP 5.6.5. Schedule options The “Auto resume of current schedule” will permit to automatically start or resume a scheduled recording whenever the current time is between a Start time and a Stop time. This permits to auto resume recording if an application or the server/PC has been reset/reboot.
DTC-325 5.6.6. Recording options If the user wants to record without notion of packets, check the “Raw Mode” option. DtGrabber+ Options settings – Recording In Raw mode, all incoming valid data bytes are stored and the Packet Size field in the main dialog is set “Raw” with orange background.
DTC-325 6. SNMP Remote Control 6.1. About SNMP Commonly used in the broadcast industry, the Simple Network Management Protocol (SNMP) is an open standard that enables management and monitoring of remotely controlled devices over TCP/IP network. SNMP is defined in RFC 1157, "A Simple Network Management Protocol (SNMP)" (*). The following link provides also a nice introduction to SNMP: http://www.cisco.com/warp/public/535/3.html (**).

DTC-325 Appendix E: DtGrabber+ deployment in broadcast environment : HE and STB Trouble-Shooting : Application Note. This Application Note details and provides concrete example about how DtGrabber+ can be deployed for troubleshooting of STB and Head-End system in real broadcast environment. When broadcast engineer or operator faces a service disturbance with low occurrence, it is difficult to identify the problem without a concrete capture of the broadcast signal at the time of the problem.
DTC-325 For his convenience, he sets up file duration to 5 minutes and the multiple file recording with autoerase rule to 12 hours. As for Multiple File recording, every file will be created with their file name stamped with the file creation time (and an index number) to help him to retrieve the proper file after a claim will be reported or an occurrence of the problem identified. As DtGrabber+ manages settings (FileName, etc.
DTC-325 In order to reproduce the problem to the satellite STB, he will use DekTec DTA-107 with DTC-300 StreamXpress to replay the recorded file and eventually set-up a specific sub-loop at the specific time of the occurrence (Check StreamXpress documentation for details). He will also be able to replay and analyze any TS problem at the time of occurrence using DekTec’s DTC-320 StreamXpert with an input adapter.
