摘要： A mobile device having first and second RF transceivers performs a communication function in accordance with a communication protocol of the second RF transceiver. During performance of this function, the mobile device estimates the RF interference on a channel of the first RF transceiver, and stores parameters which characterize the estimated RF interference in association with an identifier corresponding to the function. These actions are repeated for a plurality of channels of the first RF transceiver, as well as for a plurality of different communication functions. When performing a communication function again, the mobile device receives an identifier corresponding to the function and retrieves stored parameters corresponding to the received identifier. The mobile device applies the retrieved parameters to the first RF transceiver for reducing the adverse effect of RF interference during reception on the channel of the first RF transceiver.

摘要： 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.
