Temporal redundancy in audio refers to repetitive patterns that can be compressed, while delay and jitter refer to variability in transmission time for voice packets over IP networks. Encoding bit-rate is the file size reduction rate during video compression, while file storage size is the actual resulting size on disk. Nyquist theorem defines the minimum sampling rate to reconstruct a signal without aliasing, while Shannon theorem establishes the maximum data rate possible over a communications channel based on its bandwidth and noise.
