Abstract
Methods for determining multiplex patterns are provided. More particularly, a multidimensional data structure is used to store multiplex patterns and indexes used to access individual ones of those patterns based on audio channel selection, audio frame size, and what other media channels have frames pending. For example, when using a single audio channel, a two-dimensional look-up table maybe used to store multiplex patterns wherein one index is the audio frame size and the other index is an encoded value formed from bits representing whether any frames are pending for other corresponding media channels.
