1. INTEGRALITY OF THE TECHNICAL INTERVENTION

The technical intervention (preservation and conservation) of these types of archives demands the use of spaces that meet humidity, temperature, and fire protection standards, as well as technology and specialized human resources, which allow guaranteeing processes that comply with international standards in terms of digital preservation.

Phases of the Intervention

PHASE I – RECEPTION.

The technical intervention requires adequate environmental and asepsis conditions, in addition to the use of human, technical and technological resources that guarantee good quality in the digital files resulting from the digitization process.

This phase includes the execution of technical processes for receiving materials, inventory and external cleaning, processes that will be executed on all the audiovisual supports to be intervened. If necessary, it would also include the transfer of audiovisual supports to Bogotá D.C. (Colombia)

1)    Reception of materials.
2)    Inventory.
3)    Packaging and shipping.
4)    Storage with technical supervision.
5)    External Cleaning.

PHASE II – INTERNAL CLEANING.

This phase includes the digitization of the prioritized audiovisual supports that will make it possible to have information in high-quality digital formats, of the contents of the supports available for intervention.

1)    Internal cleaning (cleaning of audiovisual tapes).
Deliverables: For the internal cleaning process, a database will be delivered that accounts for the results of the process.

2)    Digitization with Automated Control.  For the analog video digitization process, two copies of the digitized materials will be delivered, which will contain the high-resolution versions for conservation purposes (ProRes 422HQ) and the low-resolution versions for consultation and cataloging purposes (H264). These materials will be delivered on LTO-8 tapes. Likewise, a hard drive will be delivered that will contain the low quality versions, which will facilitate access for consultation and a database that will relate the technical issues found during the process.


PHASE III – BASIC AND ADVANCED CATALOGING AND RESTORATION. 

Cataloging: A description of the content of each of the audiovisual documents is made. It involves the description, among others, of the production context, content attributes and physical characteristics of each unit:
The cataloging addresses the following principles:

1.    Content recovery from the creation of metadata
2.    Database interoperability
3.    Historical assessment of the material

a)    Basic cataloging.
b)    Advanced cataloging.

Selection of elements for physical restoration. In conjunction with representatives of the Television System duly authorized for this purpose, prioritization will be established for the restoration of audiovisual supports with reproducibility difficulties detected in the previous phases. In this activity, different parameters will be considered such as formats, the state of conservation of the supports, the production date, and the historical importance of the materials, among others.

The audiovisual and sound archive of the State Radio and Television System of any country is considered a Cultural Heritage of the Nation and therefore must be protected and safeguarded.
 
UNESCO has declared the heritage nature of audiovisual and sound archives for member countries, highlighting the value of the archive as a world heritage site due to the content contained in its records. This declaration was included in the Recommendation on the Safeguarding and Conservation of Moving Images, adopted by UNESCO in October 1980. Likewise, the records of cultural manifestations specific to the nation are considered Intangible Cultural Heritage, already declared or susceptible to be, in accordance with the “Convention for the Safeguarding of the Intangible Cultural Heritage”, adopted by UNESCO in 2003, as well as in the Guidelines for the Safeguarding of Documentary Heritage – Memory of the World, of 2002.
 
Below, the sections of the documents and the relevance of their adoption to ensure the preservation and conservation of the Television Systems archive are described, with the ultimate objective of promoting the safeguarding of invaluable and irreplaceable documents for the history of the countries:
 
Recommendation on the safeguarding and conservation of moving images, adopted by UNESCO in October 1980.
 
There, the member states adhere to different considerations in which audiovisual and sound archives are valued as the heritage of nations, and ensuring their safeguarding is established as the duty of member states.
 
Any damage inflicted on that heritage is irreversible, and each State has the duty to “adopt appropriate measures for the safeguarding and conservation of moving images taking into account the obligations imposed on them by international law.”
 
In addition, this document recommends a series of administrative, legal and technical measures where member states are invited to:
 
• “Take measures whereby officially recognized archives are able to acquire for safeguarding and preservation any part or all of their country’s national production.”
• “Take all the necessary measures in order to safeguard and preserve the moving image heritage, and, where possible, to enhance the technical quality; where the reproduction of moving images is involved, due regard should be given to all the rights in the images concerned”
• “The safeguarding and preservation of all moving images of national production should be regarded as the highest objective. However, until such time as developments in technology make this feasible everywhere, in those cases where it is not possible, for technical reasons of cost or space, to record all publicly broadcast moving images or to safeguard and preserve on a long-term basis all the material deposited, each Member State is invited to establish the principles for determining which images should be recorded and/or deposited for posterity, including 'ephemeral recordings' having an exceptional documentary character. Those moving images which, because of their educational, cultural, artistic, scientific and historical value, form part of a nation’s cultural heritage should be retained on a priority basis. Any system introduced to this end should foresee that selection should be based on the broadest possible consensus of informed opinion and should take particular account of the appraisal criteria established by the archival profession. Furthermore, due care should be taken to prevent the elimination of material until sufficient time has elapsed to allow for the necessary perspective. Material eliminated in this way should be returned to the depositor.”
 
General Guidelines to Safeguard Documentary Heritage - Memory of the World, UNESCO 2002 
 
The Memory of the World programme, created in 1992, is conceived with the premise that “the world’s   documentary   heritage   belongs   to   all,   should   be   fully   preserved   and   protected  for  all  and,  with  due  recognition  of  cultural  mores  and  practicalities,  should be permanently accessible to all without hindrance.”
 
Among the preservation principles set out in the guidelines, it is worth highlighting:
 
• Careful  documentation  and  collection  control  -  “good  housekeeping”  -  is  a precondition  for  preservation.  Depending  on  the  material  in  question,  the  mechanism may  be  a  catalogue,  an  inventory  or  some  other  form  of  recording  the  shape  and content  of  a  collection  down  to  the  level  of  individual  carriers.  
• Storage  environments  –  including  temperature,  humidity,  light,  air  pollutants, animals  and  insects,  physical  security  - should,  as  far  as  possible,  be  such  as will maximize  the  life  of  the  carriers  being  stored.
• Conserving  an  original  document  and  protecting  its  integrity  means  that  no information  is  lost,  and  all  future  options  for  preservation  and  access  are  kept  open. Original  documents  often  have  intrinsic  worth  that  will  never  accrue  to  a  copy.   
• Putting  long-term  preservation  at  risk  in  order  to  satisfy  short-term access demand  is  always  a  temptation,  and  sometimes  a  political  necessity,  but  it  is  a  risk that  should  be  avoided  if  possible.
 
“Convention for the Safeguarding of Intangible Heritage”, adopted by UNESCO in 2003. 
 
The importance of valuing the content of the archive of the State Radio and Television System of Panama within the definition of Intangible Heritage lies in the unique character of the contents that make it up, concerning the records of historical moments for the country recorded in audiovisual and sound supports.
 
In accordance with the 2003 convention, UNESCO defines intangible heritage as any heritage that must be safeguarded and it means “the practices, representations, expressions, knowledge, skills – as well as the instruments, objects, artefacts and cultural spaces associated therewith – that communities, groups and, in some cases, individuals recognize as part of their cultural heritage. This intangible cultural heritage, transmitted from generation to generation, is constantly recreated by communities and groups in response to their environment, their interaction with nature and their history, and provides them with a sense of identity and continuity, thus promoting respect for cultural diversity and human creativity.” 
 
In the recommendations of the Convention, states must:
 
• Article 11: 
a) Take the necessary measures to ensure the safeguarding of the intangible cultural heritage present in its territory
 
b) Identify and define the various elements of the intangible cultural heritage present in its territory, with the participation of communities, groups and relevant non-governmental organizations.. 
 
• Article 13
d) Adopt appropriate legal, technical, administrative and financial measures aimed at:
(...) iii. Establishing documentation institutions for the intangible cultural heritage and facilitating access to them. 
 
• Operational Directives 1.3.- 3
States Parties are encouraged to propose national, sub-regional or regional programs, projects and activities for safeguarding intangible cultural heritage. 
 
The archive managed by the Television systems has special conditions and no representative antecedents that are comparable to it, so, to the guidelines cited above, the obligations at the head of each channel derived from the regulations of each country must be added.
