Volume control arrangement for compressed information signals
The arrangement of the invention allows for modifying amplitude, frequency or phase characteristics, for example, of an audio or video signal in a compressed signal system without altering the encoder or decoder employed by each conferee in communications information conferencing. A control network...

| description | The arrangement of the invention allows for modifying amplitude, frequency or phase characteristics, for example, of an audio or video signal in a compressed signal system without altering the encoder or decoder employed by each conferee in communications information conferencing. A control network inserted between the encoder and decoder permits demultiplexing the compressed bitstream signal into sensitive parameters of the signal to be controlled, as well as into those parameters whose characteristics are not of concern. The control is then effected on the parameters of concern, in a way so as to eliminate the signal degradation associated with general tandeming signal decoding and coding operations of all characteristics in establishing the scaling control desired. |
