functional self-contained modules. The database<br />
of VideoArchive is similar to the AutoPlay and<br />
NewsHouse database, therefore it is possible<br />
to upgrade to any of these systems. Hardware<br />
components of the system are the database server,<br />
media and video servers, tape or disk libraries, client<br />
workstations, VTRs.<br />
VideoArchive provides reliable data storage with<br />
built-in self-test and backup functions. The system<br />
can easily be scaled by the extension of existing or<br />
adding of new storages. The scaling of the system<br />
can be carried out without stopping the complex<br />
operations.<br />
Media Materials Storage<br />
The basic unit of materials storage is a clip consisting<br />
of audio-video file and its description - metadata.<br />
The VideoArchive system has a distributed data<br />
storage structure. All service information and<br />
metadata are located on the database server. Media<br />
materials can be stored on different types of storage<br />
devices. Depending on the access time to materials,<br />
storage devices are divided into on-line (available<br />
immediately and do not require human input), nearline<br />
(available through minor interval of time and<br />
do not require human input) and off-line (available<br />
after a considerable period of time and require<br />
human input). The on-line storage devices are video<br />
and media servers, near-line - tape or disk libraries,<br />
off-line - external computer storage devices or tapes.<br />
The VideoArchive tools provide complete freedom<br />
of media materials control within the system. Any<br />
individual or group copy and transfer of media files<br />
between the storage devices are available.<br />
One clip can simultaneously have multiple copies<br />
on different storage devices, including a copy of<br />
the video in low-resolution, which is always stored<br />
on-line and loaded first in the video window of user<br />
interface.<br />
Operation<br />
The process of adding a new material to the archive<br />
includes a new clip creation in database, text<br />
description input (to the standard fields or in any<br />
form), digital or analog video signal record to a video<br />
server disk array, ready files import from NLE system.<br />
During the import, the video files recompression<br />
with another codec and sound processing by the<br />
integrated sound processor are possible. If the<br />
material is placed only on videotape and does not<br />
have low resolution copy, the on-line access will<br />
consist only metadata stored in the database.<br />
Integrated filters provide fast and efficient search<br />
of materials by a variety of criteria. Special<br />
categories filled by user allow description and<br />
search standardizing, increasing the speed of the<br />
required materials selection. If the found materials<br />
are on the on-line storages, they can be previewed<br />
and exported to any network station, copied or<br />
transferred to other system media storages.<br />
If the found materials are on the off-line storages<br />
(or user actions require the involvement of off-line<br />
storages), an electronic application entering to<br />
the archive service is created. In this case the<br />
following actions can be performed: the transfer of<br />
material to and from tape cassettes, tapes backup,<br />
tapes handing over and taking back, the transfer<br />
of materials from the archival tapes to external,<br />
registration of new and writing-off the old tapes.<br />
The transfer of material to/from the tape is carried<br />
out using the Azimuth video servers. When video<br />
exporting, recompression with another codec is<br />
possible.<br />
User generated the application always sees its<br />
completion status. For greater convenience of work<br />
with off-line storages, the VideoArchive system<br />
supports barcode printers and scanners.<br />
All user actions are strictly regulated by the access<br />
rights.<br />
Additions<br />
VideoArchive can be useful to those television<br />
companies that already have video servers from<br />
other brands. Most of them do not have built-in tools<br />
for video describing and search and work only with<br />
files on the hard disk. In this case, VideoArchive can<br />
store large amount of data and provide quick search.<br />
When materials are required for broadcasting, they<br />
will be automatically copied to a network storage<br />
(in this case - video server array). Yet the copying<br />
process can be carried out with separate files<br />
(standard export function) and in stream mode.<br />
Thus, VideoArchive can increase productivity by<br />
optimizing business processes and eliminating<br />
unnecessary operations. The VideoArchive system is<br />
a safe investment and guarantee of profit.<br />
