Connections & MainConnections

Connections

A connection connects a source to a sink to let audio data flow. The direction of the flow is always source to sink. For each connection the connectionFormat must be defined when the connection is demanded, if source or sink is not capable of supporting this format, the connection cannot be established. ConnectionFormats are product specific, also are some standard formats defined within GENIVI that can be enhanced in the product area. Examples of formats: analog, autodefined, stereo 48khz 16bit PCM, ....

Mainconnections

is visible to the HMI and consists out of one or more connections. A MainConnection shall always connect a Source and a Sink visible to the HMI. In contradiction to connections, the MainConnection does not know about connectionFormat. MainConnections are demanded by the commandInterface. This picture demonstrates the relation between MainConnections and connections:
