A method for evaluation of parasitic frequency modulation (wow) in archival audio is presented. The proposed approach utilizes sinusoidal components as their variations are highly correlated with the distortion variations. The sinusoidal components are extracted from audio signal by means of sinusoidal modeling procedures being often severely distorted and in case of wow also signficantly modulated.../...

In this paper an algorithmic approach to the wow defect characteristic evaluation is presented. The approach is based
on a sinusoidal analysis comprising both amplitude and phase spectra processing. The frequency trajectories
depicting the distortion are built on a basis of amplitude, frequency and phase dependencies and are further used for
wow characteristic evaluation. Additionally the experiments concerning the neural-network-based prediction applied
to the characteristic are performed. The obtained results are compared to linear-prediction.../...

The aim of this study was to investigate the emission of volatile organic compounds (VOCs) in magnetic tapes after several decades of natural ageing at room temperature. Headspace solid-phase microextraction was used as a sample preparation technique and gas chromatography-mass spectrometry was used to characterise the VOCs. Eight samples of polyester-based magnetic tapes having a magnetic coating made of a poly(urethane-ester) polymeric binder, various additives and magnetic particles were investigated. The compounds identified in the samples were fatty acid ester lubricants, compounds from antioxidants such as 2,6-bis(1,1-dimethylethyl)-4-methyl-phenol, manufacturing by-products
such as cyclic polyester oligomers, and deterioration compounds from the magnetic coating. Homologous series of carboxylic acids, furanones and aldehydes have also been identified. The latter compounds were exclusively present in the magnetic coating and could be related to the odour intensity by odour sensory ranking testing. These compounds are most likely to be the source of the often reported characteristic smell.

Archives documentation based on content analysis
The developments of computer systems in terms of memory and capacity in the last years, as well as the overwhelming phenomena of wide band networks, have revived in the international scientific community the drive to investigate and test novel audiovisual content analysis tools and algorithms. The principal aim of these techniques is to provide users with powerful automatic classification and description tools allowing for considerable cost savings and efficiency in a wide range of content search and retrieval processes. Quite obviously, broadcasters and content providers represent a prime target for the results of these efforts due to their relevant investments and interests in audiovisual archives. This paper proposes a critical review of the state of the art in content analysis from the point of view of the
applicability in real contexts and operating environments. In addition it presents some results carried on at RAI in the field of automatic documentation and classification of archive content based on these tools.

Archiving digital content can occur at different points in the broadcast
chain. Generally these can be classified as either "pre-transmission" or
"as-transmitted". In both cases the archiving of traditional linear content,
e.g. video and audio, is reasonably well catered for, though often relying on
solutions developed for analogue broadcasting. However, at present there is
little technology available to archive interactive content due to the
diversity and nature of the deployed technologies.
This paper describes ongoing research into the archiving of as-transmitted
interactive content.

Blotch Detection for Digital Archives Restoration based on the Fusion of Spatial and Temporal Detectors,
This paper proposes a method based on the Dempster-Shafer evidence theory for the detection of blotches in digitized archive film sequences. The detection scheme relies on the fusion of two uncorrelated fast, no motion compensated, spatio-temporal blotch detectors. The imprecision and uncertainty of botch detectors are modeled using Dempster-Shafer evidence theory, which improves the decision, by taking into acoount the ignorance and the conflict between detectors. We found that this combination scheme improves the global performance, and compares favorably to the motion compensated, complex and time consuming blotch detection methods, for reat archive film sequences.

Creating rich Metadata in the TV Broadcast Archives Environment: the PrestoSpace project
This paper describes the part of the PrestoSpace project dedicated to the study and development of the Metadata Access and Delivery (MAD) system. The mission of the MAD system, inside the wider perspective of the PrestoSpace factory, is to generate, validate and deliver to the archive users metadata created through the employment of both automatic and manual information extraction tools. Automatic tools include audiovisual content analysis and semantic analysis of text extracted by automatic speech recognition (ASR). The MAD publication platform provides access and search facilities to the imported and newly produced metadata in a synergic and easy-to-use interface.

Detection and Tracking Scheme for Line Scratch Removal in an Image Sequence
A detection and tracking approach is proposed for line scratch removal in a digital film restoration process. Unlike random impulsive distortions such as dirt spots, line scratch artifacts persist across several frames. Hence, motion compensated methods will fail, as well as single-frame methods if scratches are unsteady or fragmented .../...

Author of this paper participated in the development of several algorithms for wow and flutter characteristic determination. The algorithms were found useful in some real-life restoration procedures, however, there was no study of their capabilities in terms of the maximal determined modulation frequency. This paper presents such a study for three algorithms, i.e. the power-line hum tracker, high frequency bias tracker, and the centre of gravity tracker. In the paper a short description of the algorithms is followed by a theoretical study of the maximal modulation frequency determined by the algorithms. Next, the experimental part is given with simulations which confirm the findings from the theoretical part. The paper ends with conclusions.

This paper presents a method for wow defect evaluation. The method is based on tonal components detection in STFT frames. Extracted harmonic elements are joined together to form tracks. The pitch variation curve pvc is created from the selected tracks. Pvc course is considered to depict the wow defect, therefore it can be used for parasite modulation removal.

Film Grain Synthesis and its Application to Re-graining
Digital film restoration and special effects compositing require more and more automatic procedures for movie regraining.
Missing or inhomogeneous grain decreases perceived quality. For the purpose of grain synthesis an existing

which is perceptually similar to a given grain template, which has high spatial and temporal variation and which can be
applied to multi-spectral images.../...

The proposed deinterlacing scheme is aimed towards high-quality progressive image output, typically for a videotape-to-film blow-up operation. This operation consists in increasing the resolution of video images, recording these images on 16mm or 35mm film and reducing the typical video artefacts (due to interlaced scanning, electronic noise), eventually adding some film-look features (color correction, motion blur,...) .../...

Integrating Domain and Paradigmatic Similarity for Unsupervised Sense Tagging,
|
Two algorithms for movie sound tracks restoration are discussed in the paper. The first algorithm is the unpredictability measure computation applied to the psychoacoustic model-based broadband noise attenuation. A learning decision algorithm, based on a neural network, is employed for determining useful audio signal components acting as maskers of the noisy spectral parts. An application of the rough set decision system to this task is also considered. An iterative method for calculating the sound masking pattern is presented. The second of presented algorithms is the routine for precise evaluation of parasite frequency modulations (wow) utilizing sinusoidal components extracted from the sound spectrum. The results obtained employing proposed intelligent signal processing algorithms, as well as the relationship between both routines, will be presented and discussed in the paper.

New algorithm for detection of the wow distortion characteristic basing on the MTS pilot tracking is introduced. By observing a variation of the pilot frequency, the depth of the parasitic modulation can be estimated. MTS is an audio coding system used in an NTSC television standard, thus the algorithm is applicable only in that type of recordings. It is based on a high-frequency bias tracking algorithm and further modified to minimize the influence of an acoustic-band audio signals which may interfere with the 15.734 kHz MTS pilot tone.

Making tree kernels practical for natural language learning.
In recent years tree kernels have been proposed for the automatic learning of natural language applications. Unfortunately, they show (a) an inherent super linear complexity and (b) a lower accuracy than traditional attribute/value methods.
In this paper, we show that tree kernels are very helpful in the processing of natural language as (a) we provide a simple
algorithm to compute tree kernels in linear average running time and (b) our study on the classification properties of diverse tree kernels show that kernel combinations always improve the traditional methods.../...

Several methods devoted to wow defect evaluation and compensation are discussed in the paper. The presented algorithms utilize time- and spectrally-based audio processing routines. The newly proposed time-domain algorithm takes an advantage of an autocorrelation analysis of short-term pitch variations. The spectrally based methods employ: spectral peak picking techniques, analysis of spectral center of gravity, and some routines for tracking high-frequency bias in magnetic recordings.../...

The knowledge of material specific film grain characteristics can significantly improve the performance of digital film processing algorithms. This paper proposes a rapid and reliable detector for film grain properties. First, homogeneous blocks concerning intensity and texture are determined by a novel measure calculated in the frequency domain. Second, based on these blocks the signal-dependent grain noise level is estimated and an image region of pure film grain is detected.

A novel segmentation-assisted method for film dirt detection is proposed. Since dirt manifests as a cluster of pixels whose intensity differs from that of its neighbourhood, we employ segmentation and assume that each small region as a dirt candidate.

This paper is a resource for those who are making a policy case
for digital archives, for digitisation programmes or for projects designed to
exploit the corresponding digital content. It sets out, in a schematic way,
arguments that have been rehearsed in recent years to support the case for
more investment in these areas, covering the nature of the case to be made,
the concepts of market failure, contingent valuation, public value and the
internal business case. Summaries are given of the main policy developments in
the area at an EU level and of some prominent case studies. A core theme
throughout the paper is the need to articulate a more specific (and preferably
quantitative) justification for investment in Digital Archives.

MPEG-7 is an excellent choice for the description of audiovisual content due to its flexibility and comprehensiveness. The drawback is that these properties also increase the complexity of descriptions and cause ambiguities which hinder interoperability. In order to partly solve these problems, profiles and levels have been proposed, but the definitions of the adopted profiles lack semantic constraints which are necessary for interoperability. We propose a profile for detailed description of audiovisual content that can be used in a broad range of applications.../...

A light-hearted scenario on a serious subject. A damsel in distress (or 'audioviusal archivist in agony and anxiety') would be in peril of losing her audiovisual content owing to deterioration (of the media, not the damsel) or obsolescence (of the formats, not the damsel). In addition, much of the content was too fragile to be handed directly to the public - and so the collection had poor access. In fact, there was a crisis - get the collection known, used and preserved - or get out of town!

The motivation for the factory approach to preservation is to minimise loss. In most situations the resources are inadequate to the task. There is a shortage of time, money, training and equipment. This necessitates deciding on the most effective means for dealing with the overall content of collections, rather than prceeding item-by-item. The factory approach is about increasing throughput by taking a systematic approach to the whole problem, and putting resources where they give the best return.

A preservation strategy is simply a schedule of actions. The plan adds the specifics. The strategy may say "conserve another 10 years and then review", or it may say "make new master copy". The strategy may even say "make new digital master copy". But it is the plan that says exactly what the conservation method will be - and the real complication comes in saying what the exact method will be for making a new master.
|
A preservation strategy is about sequence and timescale. All the elements in the preservation map that need attention are put in a priority sequence - and time information is added according to how long you want the work to last, or how long the funding lasts, or how long the material itself will last.

Preservation is a strategic issue. Consider the long-term purpose of the preservation work - Collection Strategy: Long-term purpose; Access; Required changes; What preservation contributes. Preservation Strategy: Selection; Conservation; Restoration; Digitisation; Documentation

Start your preservation journey by finding out where you are: what's on the shelves. This information gives you a map of your audiovisual collection.

For audiovisual materials, preservation is maintenance. Using the word maintenance promotes the idea that preservation activity must be performed, funded and included in the standing maintenance functions of any organisation responsible for audiovisual material. Organisations that don't maintain their assets - that don't preserve their audiovisual content - are simply not being responsible.

Assets are the individual programs or recordings which are held by the archive.
|
Most broadcasters now handle a large proportion of their production and broadcast activities in digital media. Often these activities are managed by an asset management system, which uses a short term file store to manage programes through the post production stage and out to broadcast. Usually these systems require additional systems to be integrated in order to provide loger term storage. It may be important for a long term archive to maintain a good functional interface with an asset managment system.

The data that represents a video or audio signal can be squeezed up to take up less storage space, and use less bandwidth in transmission, by the use of compression. There are an array of techniques and standards for compression, and they can be based on pattern repetition, the human ear's limits of audio detail recognition, simple numerical techniques or any combination of these. Encoding <g> generally includes a degree of compression
|
Data is digital information that can be interpreted to reproduce the stored assets
|
A circular piece of material designed to store digital data - access is achieved by spinning the disc at a high rate past read or write heads.
|
Storage solution in which each individual asset is stored on a dedicated specific individual piece of media. In other words, each program has it's own tape.
|
The process of taking a raw audio, video or composite signal, and turning it into a digitised file. Encoding can include the process of compressing the data.
|
Fibre optics are capable of moving very large amounts of data, but they're also quite expensive compared to other forms of computer networking. Fibre Channel architecture in storage systems uses fibre optics in limited areas of the system, typically just in the Back Plane<g>, to get maximum advantage from the technology for the lowest cost. Fibre channel can be extended beyond this area though, to support an entire SAN<g>.
|
A file is a 'chunk' of digital data that contains all the necessary information to represent a stored asset.
|
A disk drive where the media is removable from the read/write device is typically called a floppy drive, as it can (but sometimes doesn't) have a flexible cover. Floppy drives are limited in their capacity because fo the mechanical contrainsts impose by being removable. This makes their capacity too small for most realistic archiving purposes.
|
A typical hard disk drive design consists of a central axis or spindle upon which the platters spin at a constant speed. Moving along and between the platters on a common armature are the read-write heads, with one head for each platter face. The armature moves the heads radially across the platters as they spin, allowing each head access to the entirety of the platter.
|
Tape in which the data tracks are written in stripes diagonally across the tape by use of a spinning head unit set at an angle to the tape. The tape itself is not in the form of a big helix or spiral.
|
The ability to automatically access one piece of media stored with others was introduced in vinyl juke boxes many years ago. Similar devices are still produced for dealing with discrete digital media (CDs for instance) and for managing Mass Storage. A juke box can mean either a virtual device on a computer system that behaves like a juke box, or can refer to a closed box-like storage device with many physical storage elemtents within it. The two meanings are not mutually exclusive.
|
Many archives use some computer systems for their cataloguing and/or stock management which they have run and maintained for many years. Though often very reliable, and frequently well integrated into operational processes which have evolved alongside them, it can be difficult to integrate such systems into newer systems without loosing some functioanilty or even some data. Such systems are called Legacy Systems.
|
This term is used to refer to i.t systems, or other components, which are inherited from earlier projects within an organisation, and which have to be integrated with the system being introduced. Legacy systems can be very difficult to work with, but may also be a crucial source of data, and their operation and the organisational behavior may be very closely linked.
|
Tape in which the data tracks are written along the tape.
|
Compression is said to be lossy if the process of copresing the dta looses some of it irrecoverably. This is often bearly audible or visible the first time it's done, but succesive generations of lossy compression encoding usually lead to a serious deterioration in the quality of the essence.
|
The Motion Picture Experts Group have defined and published a series of standards for encoding video and audio assets. These standards are sometimes based on patented technology, and implementations of the standards frequently require the use of licesned software. The different MPEG standards are listed below.
|
Magnetic storage relies upon changes in the magnetic fields found on a tape or disc to hold data. Magnetic media come in a wide variety of physical forms with several varieties of tape and disc available. Discs typically have built in read and write devices, tapes usually need to be inserted into a record or playbeck device to be accessed.
|
Storage solution in which all the assets (programs, recordings etc.) are kept on common media (disks, tapes etc.) and access is managed through a file management system
|
In the context of the storage of an archive, the media are the physical tapes disks or other objects on which the data is stored.
|
Metadata is information about the assets, or about the data that the assets are soted in, or about the media that the data is held on. Metadata is used to manage the assets, data and media in the archive, and it is of crucial importance in the functioning of the archive.
|
A type of software that fits in between the 'layers' of a complex system and allows the different components to reliably communicate.
|
Gordon Moore was a researcher at IBM who first recognised and neatly encapsulated the fact that IT development procedes in a roughly logarithmic fashion, doubling speed, capacity or affrdability every three years.
|
Network Attached Storage s the use of mass storage devices attatched directly to the geeral IT network without a great deal of intervening tehnology.
|
Open source is a term used to describe a way of designing, developing and distributing software. All software has a 'source code', written in a programming language, and an 'executable' in machine code. This source code is openly available to the public in open source software, allowing users to modify and recompile the executable to their own ends. Typically such software is distributed under a common or public licence.
|
In order to simplify the integration of complex IT systems, many developers use open standards. These are defined in a way that makes it easier for two seperately written pieces of software to communicate, even if they have been built by developers working completely independantly. Open Standards also tend not to depend on expensive intellectual property, such as patents and copright, which is beneficial in maintaining good techncal communication and keeping development and licensing costs low.
|
Open systems have published specifications. This eases the development of integrated systems that include open systems components.
|
Optical storage refers to media such as CDs, DVDs and other devices where lasers are used to write to and read from the discs. Optical media tends to be the same size and shape as a commecially available audio CD, but there are many standards currently available, and more on the way, and compatability between them must be carefully managed.
|
Some suppliers of database or A/V asset management systems provide systems that are based largely on standards that are the intellectualy property of that company only, or which are used under limited license. Whilst the use of
|
In computing, a redundant array of independent disks (more commonly known as a RAID array) is a system of using multiple hard drives for sharing or replicating data among the drives. The benefit of RAID is increased data integrity, fault-tolerance and/or performance, over using drives singularly. In its original implementations (in which it was an abbreviation for ""Redundant Array of Inexpensive Disks""), its key advantage was the ability to combine multiple low-cost devices using older technology into an array that together offered greater capacity, reliability, and/or speed than was affordably available in singular devices using the newest technology.
|
Robots are frequently used in tape based storage solution (either mass storage or discrete storage) in order to move the tapes between the storage space and the record and replay devices.
|
A Storage Area Network is a dedicated high speed network devoted to handling the storage needs of an organisation, separate to, but connected with the general IT network.
|
"SCSI stands for ""Small Computer System Interface""
|
The largest change in ATA happened with the introduction of Serial ATA. This interface uses 7-pin cables for the data connection, and transmits the data serially rather than in parallel. In addition, Serial ATA should give users the ability to hot swap hard drives.
|
Solid state storage is based on a range technologies that allow the storage of data permanently in chips. Flash ROM chipsand computer memory are the most common current applications due to the high costs at the moment, but technological advances are swift in this area, and solid state may become a viable solution for high volume long term storage within the next five to ten years.
|
Tape storage media for digital data is typically produced in a cassette. The data can be written in either a linear or helical format- linear tapes are simpler and more reliable, helical tapes have, on average, a higher data density.
|
Media that can be written on only once, but read many times with confidence, is of great interest to archivists. In the analogue domain, vinyl and film both have this facility. In digital media, only optical media have this property, but re-writable media can be used as if they were Write Once, Read Many through the use of sophisticated encoding. Probably.
|
The storage of information by the modulation of resistance or magnetic flux or some other physical property of a storage medium in proportion to some measured aspect of the information to be recorded.
|
A database is a structured file containing data, with associated functions for searching and sorting that data.
|
The storage of information by converting it into a series of numerical values from which the original asset can be restored. The numerical values are tyically represented in a binary form, using only ones and zeros. Discrete Digital Storage Media hold digital signals that contain the essence of a programme or segment.

An international metadata conference in association with The Bridgeman Art Library, BAPLA and MDA. Hosted by The MILE Project, this conference workshops and showcases the latest cataloguing standards for image archiving, with key speakers including Murtha Baca, Head of Vocabulary Program and Digital Resource Management at The Getty Institute and author of Cataloguing Cultural Objects, and Monika Hagedorn-Saupe, Deputy Director of Stiftung Preussischer Kulturbesitz. The basis of this event is the need to address the key issues associated with the global harmonisation of metadata, and to tackle these via a combination of focussed debate and workshops on key standards such as CDWA Lite, museumdat XML and OAI. We believe it is especially important that with the current increasing interest in metadata we should focus attention on metadata for opening access to the major cultural resources represented by national collections.
