Abstract: Content determination, in an online collaboration environment, moved from each client to a server, where the server reviews signal characteristics to determine the content in the data stream, may be provided. First, an online collaboration server receives a data stream associated with an online collaboration session. A traffic analyzer at the frontend of the server analyzes the data stream to determine a signal characteristic. Based on the signal characteristic, the traffic analyzer generates a classification of a type of content in the data stream. This classification is sent to an online collaboration application at the client. The client can then adjust the encoding of the data based on the type of content in the data stream.
