ABSTRACT:
A method and system for synchronizing signals. First and second signals are sent (compressed or uncompressed) from a source to a receiving apparatus of a receiving system. The first signal has content of a first modality (e.g., audio) and the second signal has content of a second modality (e.g., video). The first and second signals are to be displayed on a display apparatus of the receiving system. The first and second signals have been time-synchronized at the source. If the first and second signals are not synchronized in time when received at the receiving apparatus, then the first and second signals may be time-synchronized at the receiving apparatus either manually or through timestamping of both signals at the source, in conjunction with use of a real-time clock at the receiving apparatus.
