Here is some original art that I have produced especially for broadcasting upon DVB-MHP channels.

The art in this collection is built around the concept of the 139 opaque colours that are specified as colours in the DVB-MHP specification, specified in the part of the specification concerning the minimum system, in relation to some circumstances stated in that part of the specification.

The art concerns a concept know by the acronym CLUT, which is defined as Colour Lookup Table. While developing the Colour Spheres picture, learning to understand which colours are needed, the acronym CLUT, perhaps to rhyme with the word shut, seemed to me rather harsh in relation to colours being used for art, so I thought that perhaps the letter u in CLUT could perhaps be pronounced as a long u, so that the acronym CLUT might perhaps rhyme with the word flute.

From this, the thought that CLUT might be Colour Flute arose, as if an imaginary type of musical instrument were being played, with notes that are represented by the available colours. From this idea I developed the imagery in the Colour Flute pictures.

I am pleased with these pictures as they combine art with scientific matters, in that the pictures are hopefully decorative in an artistic sense, yet are also useful for demonstrating, and perhaps testing, the colour capabilities of DVB-MHP televisions.

The art consists of six gif files, each of which is 768 pixels wide and 576 pixels high. Care has been taken to have a border around the edge.

The art in this collection, protected by copyright, is provided on the basis of being free to broadcast content for DVB-MHP channels.

Each item is presented here using two hyperlinks, namely a hyperlink to a web page displaying the picture at full size, and a hyperlink as a direct link for copying the gif file. Readers may find that a right button mouse click on the hyperlink for the gif file is the best way to save the gif file to local storage.

Readers might like to set their web browser at full screen view as the pictures are rather large for a web browser in normal viewing format.

Colour Spheres.
Discs in 139 colours on a black background. As one of the discs is also black, the black disc cannot be observed.

Colour Spheres Transparent.
Discs in 139 colours on a Java orange background, the background then made transparent. The Java orange colour happens to be red=255, green=200, blue=0 on the PC used to produce these pictures. The Java orange colour is not one of the 139 colours.

Totally Transparent.
A totally transparent gif at the 768 pixels wide by 576 pixels high size.
I do not presently know whether this particular file might be useful. However, it seems something worth producing for completeness as it is better to have it available and not used than not to have it available and some use be found for which a file is not available. Perhaps someone will find it very useful for some particular effect.

Do all cyberspaces have walls?
This picture is, in fact, completely black.
It is included partly because it may be useful as a spacer between pictures in a sequence. The other reason for including it is because there is a free on-line gif editor at http://www.gifworks.com and one needs a gif to edit in order to use the free on-line gif editor. So, if people who are interested in producing art for the DVB-MHP platform use the gifworks facility and need a gif to edit, then this completely black picture may be useful as a background onto which to place lettering.
When asked for the file name for a file, simply add the following to the http:// that is provided in the text box at the gifworks website.
