Cambridge Imaging Systems’ Box of Broadcasts system (BoB) is a feature rich and highly configurable off-air recording system which has been developed over a number of years, principally for use by the MOD, BBC Monitoring, the BUFVC (British Universities Film and Video Council) and Bournemouth University’s Centre for Excellence in Media Practice.
BoB is controlled with a web browser based scheduling interface. From
a simple EPG (Electronic Programme Guide) displaying the next seven days
Freeview TV and Radio, users can select recordings at the click of a mouse
button. They can also search from a database of programmes coming up over
the next seven days by programme title or keyword and record items from
the search results.
The selected programmes are recorded at the time of broadcast and made available in the user’s personal account. More importantly, they are added to a long term archive of programmes available to everyone. Metadata records for the archived programmes are created from the EPG information and users can enrich or correct the data at any time. A long term archive of programmes is then built up which can be accessed by anyone from a google style search box. Finding a programme is simple – search for a word or phrase and choose from the available hits.
BoB also provides the opportunity to add programmes to the archive which have already been broadcast. Our customers know from experience that many requests for programmes happen after transmission. For this we provide a short term archive of the major channels – usually lasting between a couple of days to a couple of weeks depending on storage available.
Users can also make shorter clips from a full programme and also add them to the database. They can also collect records in their own playlist and make them accessible to the other users and tagging is also available which provides a ‘Folksonomy’ allowing the user to classify data themselves.
Imagen Database Client
Full management over your programme archive. Search, delete, modify
Tape Ingest Add material on tape to your BoB archive. Works with
any tape deck which supports Sony Contol Protocol.
ImagenLite Add digital material (Mpeg-2, QT, WMV, AV to your BoB
Media Plan Set up blanket record schedules and control which channels
are accessible by BoB Users. Full control over all Scheduled recordings.
Archive View Graphical view of MPEG-2 Transport streams held in your
Buffer. Archive View allows you to extract raw MPEG-2 for offline
editing, add to the database, transcode to another format or prepare
a file to burn to DVD.
Scope and sizing
Cambridge Imaging’s BoB system (Box of Broadcasts) typically utilises
RAIDs ranging in size between 1TB and 20TB, although it will happily
sit on top of much larger systems. The system is extremely scalable.
Any size RAID can be added to the system at a later date, instantly
increasing the amount of disk space available for online media.
Support for Analogue sources
Support for Satellite channels
Ordering facilities – output to DVD
Easily add Extra Transcoders and Storage
We prefer to use industry standard protocols and interfaces and
embrace the use of open-source code to speed development and to keep
costs down. We have experience of integrating our software with many
different types of administrative, commercial and industrial systems.
We use open interfaces based upon SOAP and XML for all of the modules
in our DAM systems and we use PHP and PostgreSQL for our web applications.
All our applications run on Windows 2003 Server platform.
Solid State, Ethernet attached, DVB Receivers developed for the BoB
system by Cambridge Imaging
Systems. These units tune into digital television stations and
multicast the MPEG-2 Transport streams onto the network. Broadcast
streams can then be saved to networked storage servers. Sgate can
stream a multiplex from a satellite feed. For more information on
T-gate click here
for a pdf. For more information on S-gate click
here for a pdf. If the network is fast enough and supports industry
standard multicast protocols, any number of users can also view broadcast
TV over the network.
This server runs the CIS Capture and FeedServer software. Together they write the unmodified MPEG-2 streams to the storage RAID, schedule and manage the available video sources, performs EPG management and indexed access to the recorded video.
This server accepts the MPEG-2 Transport stream and transcodes to
a variety of formats such as H.264, Flash Video, Quicktime, WMV and
MP3 and AAC.
Database and Web Server
The Database and Web Server offer universal access to the live EPG
data, scheduling controls and the long-term program archive. Administrators
also have access to usage statistics and archive management.
The RAID is used for storing the short term 48+ hours TV buffer. It also stores all the programmes in the archive in all formats created by the transcoder. RAIDS ranging in size between 3 and 20TB are typically installed as part of a BoB system.
