TEMPORAL ALIGNMENT SYSTEM AND METHOD

摘要

A temporal alignment system and method divides and transports video frames and uses average picture level in determining whether data sets within a particular frame are misaligned.

1. A system for detecting temporal misalignment in video frames that are divided for transport, the system comprising:
a signal divider for dividing a single signal S into N signal portions S1 . . . SN; each signal portion for carrying a portion of the same video frame; N transport links, each link for receiving a respective signal Sx from the signal divider and for delivering a signal Sx′ to a signal reassembler (1≦x≦N); the signal reassembler for selectively reassembling signal portions S1′ . . . SN′ corresponding to S1 . . . SN into a single signal S′; and, a misalignment monitor colocated with the signal reassembler; wherein the monitor utilizes information inherent in the signal portions S1′ . . . SN′ to detect whether temporal frame misalignment has occurred.
