Digital video

There is a single key operation that any multimedia system has to perform which makes it different from a normal PC: it has to be able to insert the video into the existing screen display, often into a special window, and still let that window be moved and changed in size as if it was a 'standard' PC window. As will be described, this can be a little tricky, especially with the more sophisticated video options that PCs now support, such as the ability to change picture resolution and colour depth on the fly.
