Reading-in of data

Copy stations and CD/DVD/BD robot solutions are important utilities to automatically read in data carrier. Additionally, the data can be converted and tagged, before they are filed in a database

SSD-CopyingModule.jpgThe ripping of data stored on a data carrier can be automated by using a copy station (SSD, CF, Cfast, USB) or a robot system (CD, DVD, Blu-Ray). Our software framework OpenRC provides the relevant features. The interfaces allow the connection to any existing workflow and software system. Each solution consists of hardware and software and can be adapted to the requirements of the customers. Add-ons can be implemented any time.

To read-in optical media (especially CD, DVD, DVD-DL, Blu-Ray or Blu-Ray DL), we use conventional CD/DVD robot systems. As optical media often stuck together - particularly if they are older - and thereby can't be picked up easily, an effective separation is necessary.

The read-in data are stored in a database. If necessary, extracted data can be converted, tagged and synchronized.

Converting of Data

To reduce the data volume of a digital archive, a change of file formats can be reasonable. The converting of data to standard file formats is also advantageous for long-term archiving.

FestplatteWe use linux libraries and command line tools to convert files. This allows on the one hand the integration of numerous common files. On the other hand, the system can easily be extended with new formats and better encoding algorithms.


When reading-in a storage media, meta data can be registered or retrieved from corresponding data bases in the internet. We distinguish between two methods: pre-tag and post-tag.

  • pre-tag: within the method pre-tag, each media has to be inserted in the burning device of a PC before the actual reading-in process starts. This is necessary to find out the corresponding ID where the required tagging information are stored. Afterwards, the read-in process is executed by the robots. Automatically, the scanned content (files, audio, video etc.) is related to the corresponding ID in the database and added to the meta data that was saved before.
  • post-tag: at this method, the media is read-in by the robotic first and the files are saved in the database connected to an ID. Afterwards, the read-in content (files, audio, video etc.) can be complemented with additional meta data by a preview or by looking-up the IDs in the internet (audio files). If the robot systems are equipped with a camera, the content can be related by comparing the recorded pictures of the media.

Data Synchronization

To find out rapidly which files are stored on a medium, a comparison with an existing database is necessary. Thereby, the files can easily be identified and a proofing process takes place trough e.g. hash sums, which can be calculated for each file that was read in.

The process of reading-in files and comparing them to hash sum databases is especially essential in the identification of criminal content. The hash sums allow the automated recognition of illegal content.
