Techniques for synchronizing a clock of a wired connection when transmitted over a wireless channel

摘要

An apparatus and method for synchronizing a multimedia interface clock between a multimedia source device and a multimedia sink device connected over a wireless channel. The method comprises measuring a frequency of the source clock signal generated by the multimedia source device, wherein the measurement of the frequency is performed using a first reference clock signal; generating a frequency-stamp message including in part the measured frequency; encapsulating the frequency-stamp message in at least one packet; and transmitting the at least one packet to a wireless receiver connected to the multimedia sink device over the wireless channel.

1. A method, performed by a device, for wireless communication, comprising:
measuring a frequency of a source clock signal generated by the device, wherein the measurement of the frequency is performed using a first reference clock signal; generating a frequency-stamp message based on the measured frequency, wherein the frequency-stamp message indicates the frequency of the source clock as a function of a frequency of the first reference clock signal; encapsulating the frequency-stamp message in at least one packet; and transmitting the at least one packet to another device over a wireless channel.
