KODIERUNG VON AUDIOSIGNALEN |
摘要 |
A system for transmitting audio signals over a telecommunications link generates the signals as two or more alternative feeds, for example at different data rates. The two feeds are encoded using coding methods having a frame structure with different frame lengths. To facilitate switching between the two, the input signal is notionally dividing into temporal portions and each is coded by taking it, plus enough of the next portion to make up a whole number of frames, and encoding it, whereby the encoded portions overlap - at least for one of the feeds. The overlap is lost upon decoding by discarding duplicate material. <IMAGE> |
