-8- A conferencing bridging technique for compressed information signals which monitors the signal energy transmitted by each conferee. When there is only one conferee speaking, the summing circuit in the bridge unit is bypassed along with the speech decoding/coding apparatus and the talking conferee's signal is broadcast to all conferees. If there is more than one conferee speaking at any given time, then only the speaking conferee's signals are routed to an associated speech decoder wherein those conferees' compressed signals are decompressed. These decompressed signals are then combined by the summing circuit and the sum is recompressed and broadcast to all conferees. Advantageously, the above-describedtechnique eliminates the signal degradation associated with tandeming of signal decoding and coding operations and permits the sharing of a smaller number of signal decoders among a larger number of conferees.

Technique de pont de conférence pour les signaux compressés d'information qui surveille l'énergie des signaux transmise par chaque participant. Si seulement un participant parle, le circuit de sommation du pont est contourné ainsi que l'appareil de codage/décodage des signaux vocaux et le signal du participant qui parle est diffusé à tous les participants. S'il y a plus d'un participant qui parle à un moment donné, alors seulement les signaux vocaux d'un des participants sont acheminés vers un décodeur correspondant de signaux vocaux où les signaux compressés du participant sont décompressés. Ces signaux compressés sont ensuite combinés par le circuit de sommation et la somme est compressée de nouveau et diffusée à tous les participants. Avantageusement, la technique décrite ci-dessus élimine la dégradation de signaux correspondant à la mise en tandem d'opérations de codage et de décodage de signaux et permet le partage d'un plus petit nombre de décodeurs entre un plus grand nombre de participants.
