Abstract

Embodiments for managing High-Definition Multimedia Interface (HDMI) data are provided. HDMI data is received at an HDMI connector of an HDMI device. The HDMI data received at the HDMI connector is transmitted to another HDMI connector of the HDMI device. The transmission of the HDMI data received at the HDMI connector to the other HDMI connector of the HDMI device is ceased during the receiving of the HDMI data at the HDMI connector of the HDMI device.

First claim

The invention claimed is:

1. A method, by a processor, for managing High-Definition Multimedia Interface (HDMI) data, comprising:
receiving HDMI data at a second HDMI connector of an HDMI device;
during a first mode of operation, causing the HDMI data received at the second HDMI connector to be transmitted directly to a first HDMI connector of the HDMI device by bypassing the processor, the processor not being connected to either of the first and second HDMI connectors in the first mode of operation;
during a second mode of operation, ceasing said transmission of the HDMI data received at the second HDMI connector to the first HDMI connector during the receiving of the HDMI data at the second HDMI connector of the HDMI device; wherein the processor is connected to the first HDMI connector in the second mode of operation;
during a third mode of operation, combining at least some of the HDMI data received at the second HDMI connector of the HDMI device with at least some HDMI data that is not received at any HDMI connector of the HDMI device; wherein switching between the first, second, and third modes of operation is automatically performed based on a time schedule programmed by a user notwithstanding a priority signal embedded within the HDMI data received at the second HDMI connector or the HDMI data that is not received at any HDMI connector is configured to override the time schedule to perform the switching; and
causing said combined HDMI data to be transmitted to the first HDMI connector of the HDMI device.

2. The method of claim 1 , further including, during the second mode of operation, causing HDMI data that is not received at the second HDMI connector of the HDMI device to be transmitted to the first HDMI connector of the HDMI device.

3. The method of claim 1 , wherein the HDMI device further includes a wireless receiver, and the HDMI data that is not received at any HDMI connector is received by the wireless receiver.

4. The method of claim 1 , wherein the HDMI device further includes a memory, and the HDMI data that is not received at any HDMI connector is stored in the memory.

5. The method of claim 1 , wherein the HDMI device further includes a system-on-chip (SoC).

6. The method of claim 1 , wherein the first HDMI connector is a male HDMI connector, and the second HDMI connector is a female HDMI connector.

7. A system for managing High-Definition Multimedia Interface (HDMI) data, comprising:
a processor that
receives HDMI data at a second HDMI connector of an HDMI device;
during a first mode of operation, causes the HDMI data received at the second HDMI connector to be transmitted directly to a first HDMI connector of the HDMI device by bypassing the processor, the processor disconnecting from both of the first and second HDMI connectors in the first mode of operation;
during a second mode of operation, ceases said transmission of the HDMI data received at the second HDMI connector to the first HDMI connector during the receiving of the HDMI data at the second HDMI connector of the HDMI device; wherein the processor is re-connected to the first HDMI connector in the second mode of operation;
during a third mode of operation, combines at least some of the HDMI data received at the second HDMI connector of the HDMI device with at least some HDMI data that is not received at any HDMI connector of the HDMI device; wherein switching between the first, second, and third modes of operation is automatically performed based on a time schedule programmed by a user notwithstanding a priority signal embedded within the HDMI data received at the second HDMI connector or the HDMI data that is not received at any HDMI connector is configured to override the time schedule to perform the switching; and
causes said combined HDMI data to be transmitted to the first HDMI connector of the HDMI device.

8. The system of claim 7 , wherein the processor further, during the second mode of operation, causes HDMI data that is not received at the second HDMI connector of the HDMI device to be transmitted to the first HDMI connector of the HDMI device.

9. The system of claim 7 , wherein the HDMI device further includes a wireless receiver, and the HDMI data that is not received at any HDMI connector of the HDMI device is received by the wireless receiver.

10. The system of claim 7 , wherein the HDMI device further includes a memory, and the HDMI data that is not received at any HDMI connector of the HDMI device is stored in the memory.

11. The system of claim 7 , wherein the HDMI device further includes a system-on-chip (SoC).

12. The system of claim 7 , wherein the first HDMI connector is a male HDMI connector, and the second HDMI connector is a female HDMI connector.

13. A computer program product for managing High-Definition Multimedia Interface (HDMI) data by a processor, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
an executable portion that receives HDMI data at a second HDMI connector of an HDMI device;
an executable portion that, during a first mode of operation, causes the HDMI data received at the second HDMI connector to be transmitted directly to a first HDMI connector of the HDMI device by bypassing the processor, the processor disconnecting from both of the first and second HDMI connectors in the first mode of operation;
an executable portion that, during a second mode of operation, ceases said transmission of the HDMI data received at the second HDMI connector to the first HDMI connector during the receiving of the HDMI data at the second HDMI connector of the HDMI device; wherein the processor is re-connected to the first HDMI connector in the second mode of operation;
an executable portion that, during a third mode of operation, combines at least some of the HDMI data received at the second HDMI connector of the HDMI device with at least some HDMI data that is not received at any HDMI connector of the HDMI device; wherein switching between the first, second, and third modes of operation is automatically performed based on a time schedule programmed by a user notwithstanding a priority signal embedded within the HDMI data received at the second HDMI connector or the HDMI data that is not received at any HDMI connector is configured to override the time schedule to perform the switching; and
an executable portion that causes said combined HDMI data to be transmitted to the first HDMI connector of the HDMI device.

14. The computer program product of claim 13 , wherein the computer-readable program code portions further include an executable portion that, during the second mode of operation, causes HDMI data that is not received at the second HDMI connector of the HDMI device to be transmitted to the first HDMI connector of the HDMI device.

15. The computer program product of claim 13 , wherein the HDMI device further includes a wireless receiver, and the HDMI data that is not received at any HDMI connector of the HDMI device is received by the wireless receiver.

16. The computer program product of claim 13 , wherein the HDMI device further includes a memory, and the HDMI data that is not received at any HDMI connector of the HDMI device is stored in the memory.

17. The computer program product of claim 13 , wherein the HDMI device further includes a system-on-chip (SoC).
