A display unit that receives first data and second data and respective first and second metadata associated therewith, and is adapted to be operatively connected to a computing unit is disclosed. The display unit outputs the first data and the second data to a user on an output device as an image. When the display unit receives a representation command applied by the user to the output device, the display unit then decides which data the representation command relates to, and either modifies and displays that relevant data on the output device without involving the computing unit, or modifies that relevant data by conveying the representation command to the computing unit and then receiving and displaying that corresponding relevant data that is modified in accordance with the representation command from the computing unit, depending on the metadata associated with that respective first or second data. |

1. A method for operating a display unit, said display unit receiving first data and second data and being operatively connected to a computing unit, said display unit using an output device of the display unit to display the first data and the second data to a user on the display unit as an image, said display unit receiving a representation command from the user that effects a modification of the data output by the output device to the user, comprising:
checking whether the representation command received by display unit relates to the first data or to the second data; when the representation command received by display unit relates to the first data then, using the first metadata associated with the first data, determining whether the representation command received by display unit and the first metadata associated with the first data: 1) modifies the first data without involving the computing unit, so that the display unit modifies the first data in accordance with the representation command and outputs the correspondingly modified first data to the user using the output device, without using the computing unit to modify the first data, or 2) conveys the representation command to the computing unit and receives first data from the computing unit that is modified in accordance with the representation command received by display unit, and outputs the correspondingly modified first data to the user by way of the output device using the computing unit, depending on the first metadata associated with the first data; and when the representation command received by display unit relates to the second data then, using the second metadata associated with the second data, determining whether the representation command received by display unit and the second metadata associated with the second data: 1) modifies the second data without involving the computing unit, so that the display unit modifies the second data in accordance with the representation command and outputs the correspondingly modified second data to the user using the output device without using the computing unit, or 2) conveys the representation command to the computing unit and receives second data from the computing unit that is modified in accordance with the representation command received by display unit, and outputs the correspondingly modified second data to the user by way of the output device using the computing unit, depending on the second metadata associated with the second data. |
