Abstract
Apparatus, systems and methods for generating a hybrid on screen display are described. A background image portion of a user interface is generated at a switching device. Video data representing the background image portion of the user interface is transmitted to a user station of a user console. The video data is modified at the user station as it is received using video data representing a user interface element that is specific to the user station. A customised user interface is displayed on a display device attached to the user station.
Claims39
A user station comprising:
- an input interface for receiving an input video signal;
- an output interface for outputting an output video signal to a display device;
- a video processing device in communication with the input interface and the output interface and configured to modify video data representing a background portion of a user interface to add a further user interface element which customises the user interface to be specific to the user station as the video data is received from the input interface and to transmit the modified video data to the output interface.
A switching device for selectively connecting a user station to one of a plurality of computers, the switching device comprising;
- a plurality of computer interfaces;
- a user station interface;
- a video switch operable to selectively provide a video path between a one of the computer interfaces and the user station interface;
- and
- video processing circuitry configured to form a background image for a user interface and output video data representing the background image to the video switch, wherein the video switch is further operable to selectively output the video data representing the background image to the user station interface.
A method of providing a customised user interface to a user console including a display device, the method comprising:
- generating a background image portion of a user interface at a switching device;
- transmitting video data representing the background image portion of the user interface to a user station of a user console;
- modifying the video data at the user station as the video data is received at the user station using video data representing a user interface element that is specific to the user station;
- and
- displaying the customised user interface on a display device attached to the user station.
