| titleOfInvention | Method and apparatus for pyramid vector quantization indexing and de-indexing of audio/video sample vectors |
| abstract | A method for pyramid vector quantization indexing of audio/video signals comprises obtaining (402) of an integer input vector representing the audio/video signal samples. A leading sign is extracted(404) from the integer input vector. The leading sign is a sign of a terminal non-zero coefficient in the integer input vector. The terminal non-zero coefficient is one of a first non-zero coefficient and a last non-zero coefficient in the integer input vector. The integer input vector is indexed (406) with a pyramid vector quantization enumeration scheme into an output index representing the audio/video signal samples. The pyramid vector quantization enumeration scheme is designed for neglecting the sign of the terminal non-zero coefficient. The output index and the leading sign are outputted (408). A corresponding method for de-indexing, an encoder, a decoder, and computer programs therefore are also disclosed. |
