noise in the soundtrack is higher than the defined
noise level.
In the last step the reconstructed soundtrack and
image are connected into one avi file. The last step is
to save the avi file in the database, then it could be
viewed by other users. The owner of the file has also
an opportunity to perform the reconstruction process
on the original file as many times as he/she wants
setting various values of the threshold. In the
database however only the newest version of the
reconstructed file is saved, therefore only this
version of the file is present in the web service.
4.4.2 Scenario 2 – avi/wav File Upload
The second scenario describes the situation when a
movie is saved in the avi file or only the wav file
with audio signal is uploaded to the service. In this
situation only audio distortions are assessed. The
reconstruction is conducted in the same way as in
the Scenario 1. The reconstructed recordings are
saved in the database and the owner of the
file has
the same possibilities of its processing as in the
Scenario 1.
5 CONCLUSIONS
As a result of the carried out research, a solution for
automatic audio-video reconstruction and archiving
system has been proposed and is now under
development. The proposed quality control
mechanism ensures that high quality recordings are
stored in the database. The system, currently being
implemented as a web application, enables users to
access the audio-video restoration services. The
Internet service allows users for uploading their own
recordings and, in exchange, the system reconstructs
them and allows downloading the restored
recordings.
