Abstract
A system and method of delivering synchronized audio and audio/video signals in the form of analog signals and streamed data over networks such a hybrid power line communications network is described. Signal magnitude matching by monitoring directly feed audio outputs is also provided.
Claims2
A system for an audio/video source, first directly fed audio outputs, and second networked audio outputs, the system comprising:
- a control;
- a packetizer;
- a network interface configured to operate with the control and packetizer to send an audio signal received from the audio/video source to the second networked audio outputs with a first delay adjustment;
- and
- a delay module configured to send the audio signal to the first directly fed audio outputs with a second delay adjustment, the delay module configured to send a video signal received from the audio/video source to the video output with a third delay adjustment, the first delay adjustment, second delay adjustment, and third delay adjustment provided whereby synchronization discrepancy between audio presentation by the first audio output and audio presentation by the second audio output is less than a first second time and synchronization discrepancy between video presentation by the video output and audio presentations by the first audio outputs and the second audio outputs is less than a second time period, the first time period being less than the second time period.
2 more elements
A method for a comprising:
- adjusting delivery of an audio signal to a networked audio output and to a directly fed audio output;
- adjusting delivery of a video signal to a video output whereby synchronization discrepancy between audio presentation by the networked audio output and audio presentation by the directly fed audio output is less than a first second time and synchronization discrepancy between video presentation by the video output and audio presentations by the networked audio output and the directly fed audio output is less than a second time period, the first time period being less than the second time period.
