Size does matter

The amount of information in the world is rising at an enormous speed.[1]
Especially the amount of image and video data is increasing as the resolution keeps increasing.
Nowadays, the standard-definition for television, 768 by 576 pixels,
is being replaced by the HDTV which is 1920 by 1080 pixels. But there is already a new standard in the making, the UHDTV or ultra-high definition television. This standard has a size of 7680 by 4320 pixels.

Following example illustrates the increase in data size between multiple standards:
this is for a frame rate of 25 frames per second and 24 bits per pixel.

figure1 : amount of raw data per second for multiple video standards

If you compare UHDTV to standard PAL, the size increases by 75 times. Both frame rate and bits per pixel will still increase in the UHDTV standard.

Where will this increase in size end?
Will we still be able to process all this data?

    • Maybe we didn’t make it clear enough that we were talking about the raw, uncompressed data that is created while rendering the images.

      We might discuss the importance of codecs in another post.
