    摘要: In a method for generating a physical layer (PHY) data unit for transmission via a communication channel, first data and second data that correspond to a unit of audio, video, and/or image information is received. The first data and the second data are encoded and modulated so that a resulting data rate of the first data is less than a resulting data rate of the second data. The first data and the second data are parsed to a plurality of spatial streams, and a single PHY data unit that includes the plurality of spatial streams is generated.
