摘要： An audiovisual encoding system using a multipass video encoder (50) and a plurality of one-pass audio encoders (70a, 70b, 70c and 70d). The number of audio encoders used by the system is equal to the number of audio tracks to be encoded divided by the number of passes required for the video encoding rounded up to the nearest integer, if necessary. The system allows the video encoder (50) and audio encoders (70a, 70b, 70c and 70d) to be used at the same time so that the encoding of the video is completed at the same time as the encoding of all audio tracks is completed, using the minimum number of audio encoders (70a, 70b, 70c and 70d).
