Explanation
Homogeneous conferencing requires all conference participants to use the exact same codec and video format. Because no transcoding or transrating occurs, the conference bridge simply mixes streams that are already identical in format - this is simpler and less resource-intensive. In contrast, Heterogeneous conferencing allows participants using different codecs to join the same conference by performing transcoding (codec conversion) and transrating (bit-rate conversion) via DSP resources. Ad Hoc and Meet-Me conferencing are initiation methods, not codec policy types. If a participant tries to join a homogeneous conference using a different codec, they will be denied or the call will fail.
