Abstract
A system and method for efficiently implementing redundancy management 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 that is used is always optimal with regard to the selected codec modes, and no re-negotiation of the codec is needed.
Claims29
A method for implementing redundant transmission in a packet switched network, comprising:
- determining available codec modes that were set from a prior negotiation with a receiving device;
- selecting a codec mode from the available codec modes;
- and
- transmitting packets with a particular frame redundancy level in accordance with the selected codec mode.
An apparatus, comprising:
- a processor;
- and a memory unit communicatively connected to the processor and including:
- computer code for determining available codec modes that were set from a prior negotiation with a receiving device;
- computer code for selecting a codec mode from the available codec modes, and
- computer code for transmitting packets with a particular frame redundancy level in accordance with the selected codec mode.
A computer program product, embodied in a computer-readable medium, for implementing redundant transmission in a packet switched network, comprising:
- computer code for determining available codec modes that were set from a prior negotiation with a receiving device;
- computer code for selecting a codec mode from the available codec modes, and
- computer code for transmitting packets with a particular frame redundancy level in accordance with the selected codec mode.
