ABSTRACT:
A signal processing system comprising a source apparatus coupled to a destination apparatus, the source apparatus being arranged for supplying the destination apparatus with a signal comprising video data, a time-stamp and synchronization data representing a time-value of an instant of said supplying, the destination apparatus being arranged for receiving the signal, synchronizing a time-value of a clock in accordance with the synchronization data, detecting when the time-value of the clock corresponds to the time-stamp and for thereupon presenting the video data at an output. The system includes a bus operable according to a time-slot allocation protocol, the source apparatus supplying the signal to the destination apparatus via the bus, the source apparatus including a first interface unit for buffering the signal until an allocated time-slot is available on the bus, the source apparatus setting the synchronization data according to an instant the signal is supplied to the first interface unit. The destination apparatus including a buffer, for buffering the signal prior to synchronizing the time-value of the clock for a predetermined interval, at least equal to a maximum wait-interval for the allocation of a time-slot on the bus, has elapsed after the instant the signal is supplied to the first interface unit.
