Abstract

A source device comprising a processor and a Wi-Fi module for communicating with a sink device to stream audio/video data. The processor is configured to one of either A) identify manufacturer and model of the sink device, retrieve input lag data for the sink device from a database indexed by manufacturer and model of the sink device, and optimize encoding of the audio/video data by adjusting transmission parameters based on the input lag data; or B) generate a signal, detect the signal reproduced at the sink device, measure the input lag between generation of the signal and reproduction thereof at the sink device, and optimize encoding of the audio/video data by adjusting transmission parameters based on the input lag data.
