ABSTRACT:
A convolutional encoder (112) comprises a controller (201), having a transmission rate (e.g. frame rate) as an input. The controller (201) initializes the encoder (112) to an initial state based on a transmission rate currently being utilized. When decoding, a decoder (300) utilizes a Trellis diagram having an initial and final state based upon the frame rate.
