Video gateway having movable screens

A display screen apparatus comprising:

• a vertical support beam having a length;
• an elongated arm;
• a display screen coupled to the elongated arm, wherein the display screen displays visual images;
• rotation means for rotatably coupling the elongated arm to the vertical support beam so that the elongated arm is rotatable about a predetermined single point at an end of the elongated arm;
• and
• sliding means for slidably coupling the elongated arm to the vertical support beam at the predetermined single point so that the elongated arm can slide along the length of the vertical support beam in a straight path.

A display screen apparatus comprising:

• a display screen coupled to the elongated arm, wherein the display screen displays visual images;
• rotation means for rotatably coupling the elongated arm to the vertical support beam so that the elongated arm is rotatable about a predetermined single point at an end of the elongated arm;
• sliding means for slidably coupling the elongated arm to the vertical support beam at the predetermined single point so that the elongated arm can slide along the length of the vertical support beam in a straight path, the sliding means comprising:
• a jack screw coupled to the vertical support beam;
• and
• a linkage slidably coupling the first end of the elongated arm to the jack screw so that when the jack screw is turned in a first rotational direction the linkage and the elongated arm move in a first vertical direction and when the jack screw is turned in a direction opposite from the first rotational direction the linkage and the elongated arm move in a direction opposite from the first vertical direction;
• the display screen apparatus further comprising:
• a cable coupled between a connection point on the elongated arm and an overhead point, wherein the overhead point is above the elongated arm so that as the elongated arm is moved in a vertical direction it swings about the pivot point as a result of the connection point's coupling to the cable;
• a motor coupled to the jack screw for turning the jack screw, wherein the motor is responsive to control signals for controlling the stopping, starting, speed and direction of the motor;
• a control system comprising:
• a memory including preprogrammed instructions;
• a processor coupled to the memory for executing the preprogrammed instructions;
• and
• an interface coupled to the processor for s ending control signals from the processor to the motor according to the preprogrammed instructions.
