In a reliable multi-cast, a concealment scheme may be applied to recover or conceal lost or otherwise corrupted packets of audio information for one channel based on the audio information of other channels in the reliable multi-cast. The concealment scheme may employ correction factors for channels derived from the channel relationships.

A method, apparatus and computer program product provide a stream binding mechanism that supports stream data pulling and pushing in a distributed or cloud based streaming environment. The method, apparatus and computer program product receive a stream register message associated with a stream from a streaming entity. The stream register message includes a binding descriptor. The method, apparatus and computer program product transmit a create connection message to a stream broker. The method, apparatus and computer program product transmit an endpoint message including a set of connection parameters of an endpoint to the streaming entity. The method, apparatus and computer program product receive a query for the stream from a stream processing node. And the method, apparatus and computer program product transmit a response to the query to the stream processing node. The response includes a set of connection parameters of the stream broker.
