Abstract:
1. A videoconferencing method comprising: compressing, by a first unit, audio data of a videoconferencing data stream to generate a compressed first audio stream; associating, by the first unit, time alignment information with the compressed first audio stream, the time alignment information usable for aligning the compressed first audio stream with corresponding video data of the videoconferencing data stream; receiving, by the first unit from a second unit, a communication about a second audio stream received by the second unit, the communication indicating a conflict between the compressed first audio stream and the second audio stream; delaying, by the first unit, transmission of the compressed first audio stream and time alignment information in response to said receiving the communication; and transmitting, by the first unit to the second unit, the compressed first audio stream and time alignment information after said delaying the transmission.
