  • the computer server 34 may be connected to more than one content server 40.
  • the display device 30 is constructed so that it is able to display video signals that are supplied to the display device 30 in a number of different formats. These include a standard NTSC video signal (which is the common analog television signal in use today), high definition television (HDTV) signals, and computer generated signals. Each of these types of signals is formatted in a different manner, so the display device 30 includes novel circuitry to permit the display of all types of signals.
  • NTSC video signal which is the common analog television signal in use today

It will be apparent to those skilled in the art, however, that a different image resolution can be displayed without departing from the overall scope of the present invention. The only limitation is that the monitor should be able to display a video signal which is sufficient to display HDTV signals and Internet web pages without further signal processing.
  • the monitor 50 includes a CPU 52.
  • the function of the CPU 52 is to control the on-board functions of the monitor, including screen displays, horizontal and vertical positioning, image geometry and other similar functions.

After the odd numbered lines are scanned, then the even numbered lines are scanned and displayed. Thus, a single NTSC frame consists of two fields that are interlaced to display a single image consisting of 525 lines. (In fact, not all of these lines contain video information. In the NTSC format, some of the lines are intentionally left blank). The frames are sequentially displayed to make up the single frame.
