Abstract
Systems, methods, apparatuses, and computer program products which generate a Precision Time Protocol (PTP) timestamp associated with a first video frame of a serial digital interface (SDI) signal and insert the PTP timestamp into at least one of a Vertical Ancillary (VANC) data space and a Horizontal Ancillary (HANC) data space of the first video frame.
Claims17
A method, comprising:
- generating, by a processor, a respective Precision Time Protocol (PTP) timestamp for each of a plurality of scanlines of a first video frame of a serial digital interface (SDI) signal, wherein each PTP timestamp is associated with a respective time of the respective scanline;
- inserting the respective PTP timestamp into a Horizontal Ancillary (HANC) data space of the respective scanline of the first video frame;
- receiving a first network message, wherein the first network message includes at least a portion of the scanlines of the first video frame and the associated PTP timestamps;
- and
- converting the scanlines of the first network message to a second video frame, wherein the second video frame includes the PTP timestamps of the first network message stored in a HANC data space of a respective scanline of the second video frame.

A non-transitory computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code executable by a processor to perform an operation comprising:
- generating, by a processor, a respective Precision Time Protocol (PTP) timestamp for each of a plurality of scanlines of a first video frame of a serial digital interface (SDI) signal, wherein each PTP timestamp is associated with a respective time of the respective scanline;
- inserting the respective PTP timestamp into a Horizontal Ancillary (HANC) data space of the respective scanline of the first video frame;
- receiving a first network message, wherein the first network message includes at least a portion of the scanlines of the first video frame and the associated PTP timestamps;
- and
- converting the scanlines of the first network message to a second video frame, wherein the second video frame includes the PTP timestamps of the first network message stored in a HANC data space of a respective scanline of the second video frame.

An apparatus, comprising:
- a processor;
- and
- a memory containing a program which when executed by the processor performs an operation comprising:
- generating a respective Precision Time Protocol (PTP) timestamp for each of a plurality of scanlines of a first video frame of a serial digital interface (SDI) signal, wherein each PTP timestamp is associated with a respective time of the respective scanline;
- inserting the respective PTP timestamp into a Horizontal Ancillary (HANC) data space of the respective scanline of the first video frame;
- receiving a first network message, wherein the first network message includes at least a portion of the scanlines of the first video frame and the associated PTP timestamps;
- and
- converting the scanlines of the first network message to a second video frame, wherein the second video frame includes the PTP timestamps of the first network message stored in a HANC data space of a respective scanline of the second video frame.
