Abstract

An apparatus, method and computer program product, for displaying video data from at least one source computer in a multi-monitor computer system, are provided. The apparatus includes a source computer interface for receiving at least video data from at least one source computer, and a multi-monitor interface for providing video data to multiple monitors. A processing structure coordinates routing of video data received via the multi-monitor interface to the monitors based on display requests received from the at least one source computer.

Claims

1. An apparatus for displaying video data from at least one source computer in a multi-monitor computer system, comprising:

a source computer interface configured to receive at least video data from at least one source computer;

a multi-monitor interface configured to provide video data to multiple monitors; and

processing structure configured to coordinate routing of video data via the multi-monitor interface to the monitors based on display requests received from the at least one source computer, during said coordinating, said processing structure configured to;

provide the sizes and availabilities of monitors interconnected to the multi-monitor interface to the at least one source computer; and

for each display request;

check whether the display request comprises a monitor identifier identifying a specific requested monitor;

if the display request comprises a monitor identifier, check whether the specific requested monitor is available;

when the specific requested monitor is available, coordinate routing of video data to the specific requested monitor via the multi-monitor interface and when the specific requested monitor is unavailable, automatically coordinate routing of video data to a different available monitor via the multi-monitor interface;

if the display request does not comprise a monitor identifier, check whether one or more of the monitors are available; and

when one or more of the monitors are available, select one of the available monitors and coordinate routing of video data to the selected available monitor via the multi-monitor interface.

2. The apparatus of claim 1, wherein the source computer interface comprises multiple source computer interface devices, each source computer interface device configured to receive at least video data from a respective source computer.

3. The apparatus of claim 1, wherein the multi-monitor interface comprises multiple monitor interface devices, each monitor interface device configured to provide video data to a respective monitor.

4. The apparatus of claim 1, further comprising:

a storage device configured to store at least video data.

5. The apparatus of claim 1, further comprising:

a network interface configured to send and receive at least video data to and from a remote computer.

6. The apparatus of claim 1, wherein the processing structure is configured to cause the display of an administrator interface for manually granting or denying display requests.

7. A method of displaying video data from at least one source computer in a multi-monitor computer system, comprising:

receiving at least video data from at least one source computer; and

coordinating routing of the received video data to monitors of said multi-monitor computer system based on display requests received from the at least one source computer, wherein said coordinating comprises;

providing the sizes and availabilities of the monitors to the at least one source computer; and

for each display request;

checking whether the display request comprises a monitor identifier identifying a specific requested monitor;

if the display request comprises a monitor identifier, checking whether the specific requested monitor is available;

when the specific requested monitor is available, coordinating routing of video data to the specific requested monitor and when the specific requested monitor is unavailable, automatically coordinating routing of video data to a different available monitor;

if the display request does not comprise a monitor identifier, checking whether one or more of the monitors are available; and

when one or more of the monitors are available, selecting one of the available monitors and coordinating routing of video data to the selected available monitor.

8. The method of claim 7, further comprising:

creating an electronic reservation record to associate the at least one source computer with the requested monitor.

9. The method of claim 7, further comprising:

queuing display requests in the event that video data is already being routed to all of the monitors.

10. The method of claim 7, further comprising:

displaying an administrator interface for manually granting or denying display requests.

11. A non-transitory computer readable medium embodying a computer program for displaying video data from at least one source computer in a multi-monitor computer system, the computer program comprising:

program code for receiving at least video data from at least one source computer; and

program code for coordinating routing of the received video data to monitors of said multi-monitor computer system based on display requests received from the at least one source computer, wherein said program code for coordinating comprises;

program code for providing the sizes and availabilities of the monitors to the at least one source computer; and

for each display request;

program code for checking whether the display request comprises a monitor identifier identifying a specific requested monitor;

if the display request comprises a monitor identifier, program code for checking whether the specific requested monitor is available;

when the specific requested monitor is available, program code for coordinating routing of video data to the specific requested monitor and when the specific requested monitor is unavailable, program code for automatically coordinating routing of video data to a different available monitor;

if the display request does not comprise a monitor identifier, program code for checking whether one or more of the monitors are available; and

when one or more of the monitors are available, program code for selecting one of the available monitors and coordinating routing of video data to the selected available monitor.

12. A system comprising:

at least one source computer;

a plurality of monitors receiving at least video data from said at least one source computer; and

at least one computing device communicating with said at least one source computer and executing a display management procedure, the at least one computing device, during execution of said display management procedure, being configured to coordinate routing of the video data from the at least one source computer to the monitors based on display requests received from the at least one source computer, during said coordinating, said at least one computing device being configured to;

provide the sizes and availabilities of the monitors to the at least one source computer; and

for each display request;

check whether the display request comprises a monitor identifier identifying a specific requested monitor;

if the display request comprises a monitor identifier, check whether the specific requested monitor is available;

when the specific requested monitor is available, coordinate routing of video data to the specific requested monitor and when the specific requested monitor is unavailable, automatically coordinate routing of video data to a different available monitor;

if the display request does not comprise a monitor identifier, check whether one or more of the monitors are available; and

when one or more of the monitors are available, select one of the available monitors and coordinate routing of video data to the selected available monitor.

13. The system according to claim 12, wherein during execution of the display management procedure, the at least one computing device is configured to present a user interface for enabling a user to view and grant display requests received from the at least one source computer.

14. The system according to claim 12, comprising a plurality of source computers and wherein each source computer is configured to display a user-selectable icon representing each monitor.

15. The system of claim 14, wherein each source computer is configured to display an availability message for each monitor in association with its icon.

16. The system of claim 15, wherein each availability message comprises, in the event that a respective monitor is associated with a source computer, information identifying the source computer that is currently using the monitor.

17. The system of claim 12, further comprising memory configured to store at least video data from the at least one source computer.
