Embodiment Construction

[0064] There may be a need to improve the robustness of the fixed bit rate scheme to information loss during transmission. The systems, methods and apparatus as described herein may be applicable to adaptive redundancy encoding of key frames of an audio signal. Such adaptive encoding may include testing multiple shared rates (eg, shared bit allocations) and frame offsets. This adaptive encoding may also include determining that the frame is a key frame.

[0065] Unless clearly limited by its context, the term "signal" is used herein to refer to any of its ordinary meanings, including the state of a memory location (or collection of memory locations) as expressed on a wire, bus, or other transmission medium . Unless clearly limited by its context, the term "generate" is used herein to refer to any of its ordinary meanings, such as operating or otherwise generating. Unless clearly limited by its context, the term "compute" is used herein to indicate any of its ordinary meanin...

Abstract

Compressibility-based reallocation of initial bit allocations for frames of an audio signal is described. Applications to redundancy-based retransmission of critical frames (e.g., for fixed-bit-rate modes of speech codec operation) are also described.
