Abstract

There is provided a device comprising a non-transitory memory storing an executable code, a hardware processor executing the executable code to receive Internet protocol (IP) packets encapsulating a video content, the IP packets including a frame having a header storing header information relating to the video content, retrieve at least one portion of the header information relating to the video content from the header, retrieve the video content from the IP packets, prepare the retrieved video content for transmission using serial digital interface (SDI) protocol, insert the at least one portion of the header information into at least one of a vertical ancillary (VANC) data space and a horizontal ancillary (HANC) data space of the prepared video content using the SDI protocol, and transmit the prepared video content using the SDI protocol, including the at least one portion of the header information in the VANC space.

First claim

What is claimed is:

1. A device comprising:
a non-transitory memory storing an executable code;
a hardware processor executing the executable code to:
receive Internet protocol (IP) packets encapsulating a video content, the IP packets including a frame having a header storing header information relating to the video content;
retrieve at least one portion of the header information relating to the video content from the header;
retrieve the video content from the IP packets;
prepare the retrieved video content for transmission using serial digital interface (SDI) protocol;
insert the at least one portion of the header information into at least one of a vertical ancillary (VANC) data space or a horizontal ancillary (HANC) data space of the prepared video content using the SDI protocol; and
transmit the prepared video content, using the SDI protocol, including the at least one portion of the header information in the at least one of the VANC data space or the HANC data space;
wherein the at least one portion of the header information relating to the video content includes a source multicast address, a timestamp, a synchronization source (SSRC) information and a contributing source (CSRC) information.

2. The device of claim 1 , wherein the prepared video content using the SDI protocol, including the at least one portion of the header information in the at least one of the VANC data space or the HANC data space, is transmitted to an IP video device.

3. The device of claim 1 , wherein the header is a real-time transport protocol (RTP) header.

4. The device of claim 1 , wherein the video content is a multicast video content.

5. The device of claim 4 , wherein the multicast video content is received from a plurality of sources.

6. A device comprising:
a non-transitory memory storing an executable code;
a hardware processor executing the executable code to:
receive a serial digital interface (SDI) signal including a video content, the SDI signal having header information relating to the video content stored in a data space of the video content;
retrieve at least one portion of the header information relating to the video content from the data space;
retrieve the video content from the SDI signal;
prepare the retrieved video content for transmission using Internet protocol (IP) packets;
insert the at least one portion of the header information into a header of the IP packets including the prepared video content using; and
transmit IP packets including the prepared video content and the at least one portion of the header information inserted into the header of the IP packets;
wherein the at least one portion of the header information relating to the video content includes a source multicast address, a timestamp, a synchronization source (SSRC) information and a contributing source (CSRC) information.

7. The device of claim 6 , wherein the IP packets including the prepared video content and the at least one portion of the header information inserted into the header, are transmitted to an SDI video device.

8. The device of claim 6 , wherein the header is a real-time transport protocol (RTP) header.

9. The device of claim 6 , wherein the video content is a multicast video content.

10. The device of claim 6 , wherein the data space of the received video content includes at least one of a horizontal ancillary (HANC) data space or a vertical ancillary (VANC) data space.

11. A method for use in a system including a first device having a non-transitory memory and a hardware processor, the method comprising:
receiving, using the hardware processor, Internet protocol (IP) packets encapsulating a video content, the IP packets including a frame having a header storing header information relating to the video content;
retrieving, using the hardware processor, at least one portion of the header information relating to the video content from the header;
retrieving, using the hardware processor, the video content from the IP packets;
preparing, using the hardware processor, the retrieved video content for transmission using serial digital interface (SDI) protocol;
inserting, using the hardware processor, the at least one portion of the header information into at least one of a vertical ancillary (VANC) data space of the prepared video content or a horizontal ancillary (HANC) data space of the prepared video using the SDI protocol; and
transmitting, using the hardware processor, the prepared video content, using the SDI protocol, including the at least one portion of the header information in the at least one of the VANC data space or the HANC data space;
wherein the at least one portion of the header information relating to the video content includes a source multicast address, a timestamp, a synchronization source (SSRC) information and a contributing source (CSRC) information.

12. The method of claim 11 , wherein the transmitting transmits the prepared video content using the SDI protocol, including the at least one portion of the header information in the at least one of the VANC data space or the HANC data space, to an IP video device.

13. The method of claim 11 , wherein the system further includes a second device having a second non-transitory memory and a second hardware processor, the method further comprising:
receiving, using the second hardware processor, the prepared video content using the SDI protocol, including the at least one portion of the header information stored in a data space of the prepared video content;
retrieving, using the second hardware processor, at least one portion of the header information relating to the video content from a data space of the prepared video content;
obtaining, using the second hardware processor, the retrieved video content from the SDI signal;
preparing, using the second hardware processor, the obtained video content for transmission using second IP packets;
inserting, using the second hardware processor, the at least one portion of the header information into a header of the obtained video content using the second IP packet; and
transmitting, using the second hardware processor, the second IP packets including the obtained video content and the at least one portion of the header information inserted into the header.

14. The method of claim 13 , wherein transmitting transmits the second IP packets including the obtained video content and the at least one portion of the header information inserted into the header, to an SDI video device.

15. The method of claim 11 , wherein the header is a real-time transport protocol (RTP) header.

16. The method of claim 11 , wherein the video content is a multicast video content.
