Abstract
A method and apparatus for communication system buffer size and error correction coding selection. A method includes the steps of receiving a stream of data packets by a real time receiver that includes a buffer management device, a first plurality of jitter buffers, and a second plurality jitter buffers. The first and second plurality of jitter buffers are evaluated and a first and a second optimal jitter buffer is chosen. The first and the second optimal jitter buffer has an associated conditional optimal performance characteristic. The conditional characteristics are compared and a preferred buffer of the receiver is selected. The apparatus includes a receiving device including a first set of jitter buffers and a second set of jitter buffers with error coding. The first set includes a plurality of buffers and a second plurality of buffers maintained in the second set of buffers. The apparatus also includes a means for comparing the first plurality of buffers and the second plurality of buffers, a means for selecting a first optimal buffer from the first plurality of buffers, and a means for selecting a second optimal buffer from the second plurality of buffers. Either the first or the second selected optimal decoder determines the receiver buffer size and whether forward error correction is utilized.
