1. A method of digitally transmitting video images in blocks, comprising:

  • setting a focus and a coordinated frame rate to a data stream of video images on the basis of available channel capacity;

    said data stream having a plurality of successive frames, each frame having a multiplicity of blocks corresponding to blocks on the successive frames;

    sensing changes by means of structural components, beyond a given difference, in image content between corresponding blocks of successive image frames; and

    softening, by means of the components and in the absence of manual intervention, the focus in response to the changes, beyond a given difference between corresponding blocks in successive frames, occurring in a number of blocks above a first predetermined number of blocks.
