TIME TRAVEL

This page shows all the types of visualisation over time that we have at present. Changing the metadata field used in the visualisation - e.g. showing how the top five broadcasters have changed instead of the top five genres, or showing how the proportion of programmes in colour has changed instead of the proportion that is digital, is very easy to do. Do you have a different type of visualisation in mind? Let us know: rordelman@beeldengeluid.nl, mwigham@beeldengeluid.nl

Deze pagina toont all types visualisatie over tijd die we nu hebben. De metadataveld in de visualisatie veranderen - bijv. de top vijf omroepen laten zien ipv de top vijf genres, of laten zien hoe de percentage kleur programma's heeft veranderd ipv de percentage digitale programmes, is heel makkelijk. Heb je een andere soort visualisatie in gedachten? Laat ons het weten: rordelman@beeldengeluid.nl, mwigham@beeldengeluid.nl

Here is the number of programmes in the archive over time. We have excluded some programmes with strange (probably erroneous) dates

This graph shows how the number of programmes ('programmes' includes photos, objects and paper documents) in the top five collections (catalogs) have changed over time. It is clear that albums (handelsplaten) come from a quite specific time range, as do the bulk of the photos.

This graph shows the top five distribution channels, and how the number of programmes in these have changed over the years. There is quite a strong correlation with the catalogs, as these are organised around the distribution channels to a certain extent.

What is digital? This is a very complex question. For example, a digibeta is digital, yet to access the information it must be physically retrieved and placed in a player. Is it then digital, or not? It depends on who is asking for the information, and why. Another question that is relevant is, what SHOULD be digital? If we have two copies of the same programme, one with captions and the other a 'clean' feed, do we need to digitise both? This information is necessary before you can decide to interpret the graph as 'how far we are in digitising the archive'. Here, we have chosen to regard digital as 'available in the media archive', and show the information for all programmes with the specified date field.

Note: The percentages are relative to the amount of material in a year. Therefore, it may appear that a particular year is 'good' for digital material, as the value is 100%. However, there may have been only one programme in that year!

This graph shows the number of programmes with a speech recognition transcript available per year (green). The yellow bars are the audio-visual programmes that are waiting for ASR, the red bars the audio-visual programmes that cannot currently be processed with speech recognition, as they have no copy in the media archive.

Here we see how the number of documents with a summary has increased greatly over time, while the number with a description has remained much lower. We could also show this graph in terms of the percentage of programmes with a summary/description

Here we see for the top five genres overall, the number of programmes with that genre per year over time.

This shows the percentage of material with a duration over time. This does not necessarily mean the duration information is what we are expecting - often '0' is filled in as a duration

This shows the average length of programmes over time. It would seem that programmes are getting longer - this should be taken with a pinch of salt, however, as programmes can also be compilations of many programmes or music clips.

The maximum length over time varies greatly, mainly due to a couple of very long programmes being entered in certain years.

This shows the change in the length of the summary text over time.
