video compression

Encoding digital video to take up less storage space and transmission bandwidth. See video codec and data compression.

video compression - Compression of sequences of images. Video compression algorithms use the fact that there are usually only small changes from one "frame" to the next so they only need to encode the starting frame and a sequence of differences between frames. This is known as "inter-frame coding" or "3D coding".

MPEG is a committee producing standards in this area and also the name of their standard algorithm. H.261 is another standard.

Hanging nearby was Arizona Landscape, 1945, a photograph in which the sun-flattened surface of the desert is punctuated by insistently vertical cactus spires, achieving a similar spatial compression in a different medium.

The shape is intended to increase the apparent volume of the undercroft, but it inevitably seems rather troglodytic (though well lit), not a bad thing in itself, for the spatial compression of the entry helps enhance the airy luminosity of the glass vaults when you approach them up the escalators.
