A system and method are developed for efficiently implementing redundancy in speech coding applications. According to various embodiments of the present invention, a sending device selects a redundant transmission level that is suitable for a current transmission channel condition while, at the same time, selecting the most suitable bit rate from the available codec mode set. With embodiments of the present invention, the redundant transmission level used is always optimal with regard to the selected codec modes, and no re-negotiation of the codec is needed. |
