METHOD AND APPARATUS FOR DETERMINISTIC DATE AND TIME ALIGNMENT OF MEDIA SIGNALS AND GENERATION OF TIME-RELATED LABELS |
摘要 |
There is described a method for generating a frame label for a media frame sampled at a media frame rate at a given time-of-day relative to a day-zero reference. The method comprises: obtaining a calendar day at which the media frame is sampled, the calendar day having a day origin; computing a day-origin phase offset at the day origin based on the day-zero reference and on the calendar day; subtracting the day-origin phase offset from the given time-of-day to get a media frame relative offset which is relative to a first frame of the calendar day; computing the frame label from the media frame relative offset and from the media frame rate; and assigning the frame label to the media frame for time-positioning the media frame with respect to other media frames and with respect to a timescale. |

1. A computer-implemented method for generating a frame label for a media frame sampled at a media frame rate at a given time-of-day relative to a day-zero reference, the method comprising:
obtaining a calendar day at which the media frame is sampled, the calendar day having a day origin; computing a day-origin phase offset at the day origin based on the day-zero reference and on the calendar day; subtracting the day-origin phase offset from the given time-of-day to get a media frame relative offset which is relative to a first frame of the calendar day; computing the frame label from the media frame relative offset and from the media frame rate; and assigning the frame label to the media frame for temporal-positioning the media frame with respect to other media frames and with respect to a timescale. |
