SYNCHRONIZATION OF AUDIO CHANNEL TIMING

摘要

Synchronization of plural outputs of data transported by a wireless network is facilitated by bandlimiting a sample clock signal controlling a rate at which data is processed by the network's devices and/or bandlimiting wall time data controlling the real time for presenting a datum.

主权项

1. An audio system comprising:
(a) a first listener including:
(i) a wall clock maintaining a wall time for occurrence of an event, said wall time updated by data transmitted by a master clock and received by said first listener;(ii) a sample clock recoverer retrieving a sample clock from data received by said first listener from a talker, said sample clock regulating a processing rate for a datum included in said data received from said talker; and(iii) a frequency filter bandlimiting said sample clock output by said sample clock recoverer; and(iv) a transmitter transmitting said bandlimited sample clock; and (b) a second listener arranged to receive said transmitted bandlimited sample clock and use said bandlimited sample clock to regulate processing data received from said talker.
