CARRIAGE OF PTP TIME REFERENCE DATA IN A REAL-TIME VIDEO SIGNAL

Systems, methods, apparatuses, andcomputer 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.

BRIEF DESCRIPTION OF THE DRAWINGS

So that the manner in which the above recited aspects are attained and can be understood in detail, a more particular description of embodiments of the disclosure, briefly summarized above, may be had by reference to the appended drawings.

It is to be noted, however, that the appended drawings illustrate only typical embodiments of this disclosure and are therefore not to be considered limitingof its scope, for the disclosure may admit to other equally effective embodiments.
