Synchronization of a split audio, video, or other data stream with separate sinks

摘要

Methods, systems, and apparatuses for synchronizing one or more output/sink devices (104a,104b) are described. In each sink device (104a,104b), a communication packet is received from a source device (102). The communication packet includes data and a source clock timestamp. A local clock signal is generated that is synchronized with a source clock signal of the source device. The data is decoded using a codec. At least one delay and the source clock timestamp are subtracted from a current value of the local clock signal to generate a local latency value. A difference between a desired latency value and the local latency value is determined (502a,502b). A rate of a clock signal of the codec is adjusted according to the determined difference. Because each sink device adjusts its latency to a common desired latency value, the sink devices are thereby synchronized.
