Constant Field Values

exp

public int exp

The exponential scaling of the mantissa for the maximum total media bit rate value, ignoring all packet overhead.

mantissa

public int mantissa

The mantissa of the maximum total media bit rate (ignoring all packet overhead) that the sender of the REMB estimates. The BR is the estimate of the traveled path for the SSRCs reported in this message.

dest

public long[] dest

one or more SSRC entries which this feedback message applies to.
