Video transmission rate matching for multimedia communication systems

摘要

Digital video transmission rate matching techniques are disclosed. A bit stream rate matching apparatus includes a bit rate increasing device and a bit rate reducing device (107). The bit rate increasing device converts a video bit stream having a first transmission rate to a video bit stream having a second transmission rate characterized in that the first transmission rate is less than the second transmission rate. The bit rate reducing device (107) converts a video bit stream (101) having the second transmission rate to a video bit stream having the first transmission rate. The bit stream rate matching apparatus is useful in the context of a multimedia conference where a first endpoint device employs the first transmission rate and a second endpoint device employs the second transmission rate.
